I wonder which Miata donated its transmission to keep mine alive? That one is probably long gone, I’d assume. However, BUY FROM THIS MAN. I’ve made a few purchases from him and all were as advertised. A year later and my 5 speed is still going strong. He’ll be my first stop as long as I have my Miata.
Every time you chuck a water pump in the scrap bin, for some reason I want someone to pop up out of the box and be like, “Oww, dammit Eric!” Thanks for the mid-week bonus video!
You are getting popular among airline pilots. We talk in the cockpit up at altitude to alleviate the boredom, and I've had more than one guy mention your videos, which I watch all of. Airline pilots always have "toys". Cars, boats, farms/farm tractors, cows, horses, wood working shops, rental properties....You name it, we all do volunteer work and we all have our toy. Mine is my '14 Cayman S, the replacement for my previous Porsche 928S2 5 speed. [Hint...] So we are naturally technical people and most of us do all our own maintenance work. As a result your videos are a big hit in our world. Next time you fly somewhere poke your head into the cockpit and shake their hands; More than likely they will know who you are. Great video!
As long as your own maintenance doesn't include the planes you fly. Or maybe you should. I'm kidding. I got my A&P after getting out of the Navy as a structural mechanic, and went to work for McDonnell-Douglas in Tulsa until the massive layoffs in the early '80s. I was doing upgrades to the F-4, among other projects.
You should grab a Miata in the shop one day and do a walk around of what to look for when buying one. Common rust points, common failures, common fixes. I want to buy one in the future and that would be great from someone that knows them as good as you.
Sold my B6 equipped Miata yesterday after 18 years of ownership and sitting here today feeling miserable about it and now this pops up and I'm even sadder... But it was still a great video, thanks Eric
I bought a 1986 model Holden VL Commodore in 2002 over here in Australia which ran the Nissan RB30E engine which was a smoker,it also stalled if you idled it for 5 minutes because the rear main oil seal was chewed out so it had a crankcase air leak. It had done 300,000 Kilometres & I bought it to replace another VL Commodore which I crashed about 430,000 kilometres & the engine wasn't smoking as bad as the one in the VL Commodore which I bought which had done 300,000 kilometres but the engine was slowly on its way out. I swapped engines but it started smoking like a chimney in 2003,I did pull that engine down & the cylinders were worn out & would need to be rebored but I stripped down the 300,000 kilometre engine prior to that to build a DOHC 3 litre engine using parts from a 1995 model Nissan R33 Skyline GTS RB25DE engine, anyhow the RB30E engine had stuck oil control rings & a chewed out rear main oil seal journal which I just sleeved it to repair the scoring & groove, I used an metallised epoxy based metal filler underneath the sleeve as well. I used the Nissan RB25DE pistons to raise the compression ratio & I fitted aftermarket 0.040" oversized Mitsubishi 4G63 piston rings since they were different (thinner) than the RB30E piston rings. That fixed the oil burning except on startup sometimes due to perished valve stem oil seals which I cheaped out on,it would blow a bit of smoke after sitting for a while because it was a bare bones budget engine build but it went heaps better than the RB30E engine !
As someone who has a short nose that broke, I was actually excited you might have a crankshaft for sale, until you said you were going to use it! My search continues, but this was still fun to watch, regardless.
Any Miata teardown is a good teardown (even if it's 1.6)! I've had my NB1 since 1999 and it's survived every bit of my "abuse". So seeing a beloved B6 or BP being torn down is like a trip down memory lane.
Ive fixed oil burners with water. Get the engine up to operating temp then spray in water at 2500 rpm. You will see steam and slowly the engine will start to run better.
My great grandfather was one of the first auto mechanics and he would do the same thing, except he would also do this on EVERY engine that he was going to have to do a tear down on. So this has been done for around 100 years!!

Once upon a time I drove a Toyota Tercel with a 3E-E. It pretty much fogged the neighborhood for mosquitoes, it burned so much oil. It went through a set of plugs every 4 tanks of gas or so. Right up until it burned a valve from the oil burning, that is. When I re-ringed it and replaced the cylinder head, the carbon was WAY worse than this engine. The only place the carbon wasn't thick was on the piston skirts lol. This one might have smoked, but it probably had a dozen or so thousand miles before it became an issue, other than fouling plugs.
2003 Subaru Forester. Using 1qt of oil at around 1000 miles. ~217,000 miles on it. I pulled it down for the sole purpose of putting new rings in it. The oil return holds behind the stuck oil rings were plugged with hard brown carbon! I literally had to clean the holes with a drill! Haven't driven it enough to know if my mission was successful.
I had a 1993 model for 22 years. Replaced it 2 years ago. In that time I replaced the clutch (didn't really need a new one) , had the rectifier fail (replaced) , two leaking clutch slave cylinders , three cam belts, a water pump and a radiator. It had 77,000km when I bought it and over 400,000 when I sold it. It used a little more oil towards the end and needed valve guide oil seals. My engine was really clean inside. I used HDEO in it (DELO 15w40 multifleet)
In this video you mentioned a design element that you would have done differently... it got me thinking that someone with your experience would have some great insights into what works and what doesn't with regard to reliability. So I'm asking.... what about a series where you tear down and/or go over some of your favorite engines and why you like them so much. I'd watch that!
I still miss my 93 1.6. It taught me so much about working on cars. I swapped out the original tired engine for a less tired JDM engine, did timing belt and water pump, gearbox, a couple of 1.6 diffs that I killed before upgrading to a rare 4.3 torsen. In the end I was sad to sell, but it had nearly 300 thousand km and I didn't have the money to maintain it properly. Geez that little B6 is a gem of an engine though, it got driven hard to redline every single day and just kept going and going. Made me a Mazda fanboy. I still have the original 1.6 big nose sitting under my house though, must dig that out and sell it one day, would be a good rebuild prospect.
Never owned a Miata (sigh), but this tear down did remind me of my childhood, when my Dad would swap grimy, grungy old engines in a series of 1950s Nashes, also an occasional Renault Dauphine, aka the French tin can. Oily grime caked all over everything that was exposed to the elements. Your parts washer would have been busy all day!

Nick from what I seen of the crankshaft if you are planning on getting it polished you need to get the oil ports chamfered for better oil flow as well.
Speaking of short nose cranks, I discovered on my current Miata, which has an escort BP from 92, it has a short nose in it. Really made my front seal replacement a massive PIA
Soooo you're saying you have a couple of Miatas?? Nice! The B6 and BP remind me of the simplicity of Toyota's 4AGE. Simple stout little engines that are a doddle to work on and can make modest power with simple engine apart mods... Great video Eric.
I’m also a BP lover, I have a couple Ford Escorts with the 1.8 BP engine. One is a 94’ Gt and the other is a 91’ Lx with the Gt/5 speed swap except for the body plastics and took me 6 years to restore the car. A local machine shop did a bad polishing on my small nose crank and it wiped out the rod bearings in about 600 miles before i heard a slight knocking noise before i pulled the engine out. Had the crank re-polished by another shop but haven’t put the engine back together yet. I have a temporary 1,8 BP that burns oil like a 2 stroke inn the car currently just to keep it drivable. I have to push the car out of the shop before starting the engine as it smokes like crazy. Lol My 94’ Gt runs great, i just recently pulled the engine and transmission to reseal/gasket them and clean up the old oil/grease, been daily driving that car for 6 months so far without any issue, and installed new headlights yesterday. It’s an auto but still a pleasure to drive.
The 'Mazda' Escort GTs were fantastic. I had the teal green, about a 92, and before that a regular 'Ford' Escort GT of 89 vintage. Actually also a very good car but the later version was superior. I know someone who put over 400k trouble-free miles on another 89 GT, though, so pretty stout cars.
Anyone know where i can find parts for my Miata? Kidding aside, this is truly one of those cars where a lot of the beauty lies in their simplicity. I built up a wrecked one for a Gambler rally a few years back and to date it is still one of the most reliable things i own.
I worked for a Mazda dealership for over 30 years (1977 to 2011), and I went to the Mazda school for these cars. I was guessing stuck rings from the beginning. This vintage Mazda had "low drag rings" in an effort to improve fuel economy. While it did accomplish the intended purpose, this was the the down side. They also were a little slower to warm up on a cold morning. One of our guys made a pretty good side business out of re-ringing B2000 trucks for a local currier company that used a fleet of them. They could get 300,000 miles out of them, but they needed rings because they would be stuck, never worn out. There was also no cylinder wear to speak of, due I am sure to the low tension on the rings.
Hey Eric, I used to have a fantasy about asking you for a job. I live in Colorado. Anyway until recently I was a mechanic at a mom and pop shop for three years. I was also a volunteer radio DJ at the community radio station. I got hired as Music Director so I quit wrenching. I'll still watch every video you make and think of what might have been!😂🤣✌❤
The late '80s and early '90s was a good time to work on cars. EFI allowed them to get rid of a lot of the weird vacuum emissions accoutrements from the carburetor era that had just ended. You often didn't need a lot of special tools to diagnose things.
I sometimes wonder if I should have stuck with port injection instead of going direct with my Lemans transplant. More compression for power and effiecency but another layer of complexity.
It's interesting to see you tear down an engine that you are VERY familiar with. It's obvious you have a totally different attitude and approach. Cool.
Back in the day I bought a 1.6 for 20$ off Craigslist and rebuilt it to replace the perfectly good engine already in my 90’ Miata. 😎Thanks for the memories 😎
I'm so excited to see my car's exact engine on this stand. The abuse these powerplants will tolerate both stock and boosted is incredible. It's no beast by any means, but it fits the character of the the NA Miatas perfectly.
"I'm not saying Ford is bad, but the mix wasn't great." Volvo shipping with Ford was also a less than ideal pairing. I'm not saying Ford is bad, but I'm sensing a theme here.
I want to know why ford did so much R&D on how to make paint stick to aluminum all through the 2000s in preparation for the aluminum f150, when they could have just copied Mazdas homework since a) they owned Mazda and b) miata hoods are aluminum and aren’t known for peeling/corroding
I have an nb1 with a 1600 engine. Travelled only 35,000km. I pamper the engine with regular servicing and the best oil available. In return I get a great ride !
There is an old trick to try if you believe that you have stuck piston rings and it (can work) but nothing is guaranteed and that is to pour WD-40 into the spark plug holes to where the piston tops are covered in fluid and let it sit and soak for a day and then turn the engine back and forth slowly (not with the starter if the plugs are installed) and let it sit for another 2-3 days checking to make sure the piston tops are covered in fluid and (each day turning the engine back and forth slowly a few times) and after about 3 -4 days suck out the WD-40 if there is any left. WD-40 will dissolve and break up the carbon crusties locking the rings to the pistons and go through into the crankcase and WD-40 mixes well with oil. I would advise doing an oil and filter change after doing this before running the engine for any long period of time like when you plan to drive it.
Apparently, you use carb cleaner first, then the WD-40 which will absorb into the carbon and make it easy to brush off. I have to do a piston soak on my Nissan 3.5, and from what I've heard/read, Chemtool B12 is the bee's knees for that.
Ha, this is what happened to my old Suzuki Swift gti when I bought it years ago. Pulled it apart, oil control rings were stuck to the pistons, after removing them had to clean the holes behind them on the piston were full with carbon deposits. After some further cleaning I slapped it back together (with new rings) and it ran amazing for another 100,00km before selling it for double the price I paid. Early 90’s Japanese engines are amazing
If you have any videos of full engine removal from an actual chassis; it would've been so useful for me months ago. But this is also incredibly fun-- I just did this entire job on my miata last week. You make it look easy!
Back in the late 1960s, my uncle(who liked to buy and sell cars) had a Corvair that burned oil so bad that you could not see if you followed it. A person bought it and was going to drive from Oklahoma to California in it He went 20 miles before the engine blew up. Also, we had a 1992 Ford Escort with a 1.8 Liter Mazda engine that went 240,000 miles before we got a new car. We did the recommended oil changes, timing belt changes, etc.
Ahh yes - the infamous LWSC (light weight sport crank) as the short-nose 1.6 was dubbed on the mailing list back in the 90s. As I recall, most failures would happen after timing belt replacement, and suspect that the biggest cause was improper torquing of the crank bolt - too loose and things are obviously gonna move, but if you crank it down too much to make things 'tighter', it can stretch and ultimately make them looser, also ending in a chewed up crank. I’d like to someday get my ‘96 back on the road, but it has terminal cancer from the liquid car dissolver used on the roads in winter here in CT.
I recently got a heap of a NA 1.6 with a long nose crank that I'm going to rebuild into a nice weekend driver. I will be watching this video as I open up the engine to see what I suspect might be rod knock. We will see! I bet I'll need parts soon...
I may be biased since I’m an 80s kid, but this is the golden age of automotive engines. Older stuff is too antiquated and sacrifices too much due to old technology (old metallurgy, single camshafts, pushrods, carburetors, etc), new stuff is over complicated to try and get inherently dirty engines to be “clean.” If you were to look at a list of top 10 best engines of all time, most of them would be from the 1990s and very early 2000s.
Can confirm when I bought my 1994 Miata it had the oil dipstick loop handle broken off. Somehow one of the easiest dipstick tubes to uninstall/reinstall but one of the worst dipsticks to actually use when it's attached to the engine due to the bends in it. Though my Miata had been messed with in so many weird ways by previous owners I can't be entirely sure they bent it to try to get another 0.3 HP or something dumb 🤷 I tell ya the combination of removed exhaust manifold heatshield and a cold air cone filter without anything to separate it from the hot engine was not the performance bonus the previous owner would've guessed 🙄
When you talked about using cheap motor oil it reminded me when different shops would sell reconditioned motor oil. I had an old Chevy Vega that burnt more oil than gas. I'd buy that reconditioned oil for less than a quarter a quart!
I just love this channel. Such a great attitude and approach to business, and even local to me. Just wish I liked working on foreign cars more, then id probably be a customer weekly, always amazingly blown up things come through my shop.
My 1989 323GTX 1.6T had the loose crank bolt and then the damaged keyway issue. The Loctite fix cured that for another 100K miles. Currently my GTX has the 1.8 BPT so no more crank nose worries.
Man that water neck on my old Mazda 323 with the BP05 engine. It got a leak in it and sprayed coolant violently. I sealed it with high temp chemi weld putty and it never leaked again
This video is relevant to my interests! Currently working on a 1990 Miata engine to swap in my ‘73 Triumph Spitfire. Picked up the engine and transmission for $250. It was allegedly an oil burner as well. I’m still working on getting it mounted so no idea how bad it will be! Hope it’s just valve seals or something easy, but it’s probably oil control rings…
This was good. Would love to also see the 16V FSDE 2.0 4 pot motors from the P5 wagons on here if possible. I drive one still that I bought used in 2012 with 110K+, and now has 198K+ and still going. Yes, despite what some say, they ARE non interference. Ask me how I know... Mine is a tad battered due to living on the streets as one, for many years, I lived in an apartment, now own my house and it does not have a driveway. Despite it blowing a tad of bluish/grayish smoke for a second or 2 if I've not started it in a day or two, it's fine otherwise. The ONLY issue is the peaky torque/power curve.
Eric is the "Bob Ross" of engines.

I’m also a BP lover, I have a couple Ford Escorts with the 1.8 BP engine. One is a 94’ Gt and the other is a 91’ Lx with the Gt/5 speed swap except for the body plastics and took me 6 years to restore the car.
A local machine shop did a bad polishing on my small nose crank and it wiped out the rod bearings in about 600 miles before i heard a slight knocking noise before i pulled the engine out.
Had the crank re-polished by another shop but haven’t put the engine back together yet.
I have a temporary 1,8 BP that burns oil like a 2 stroke inn the car currently just to keep it drivable.
I have to push the car out of the shop before starting the engine as it smokes like crazy. Lol
My 94’ Gt runs great, i just recently pulled the engine and transmission to reseal/gasket them and clean up the old oil/grease, been daily driving that car for 6 months so far without any issue, and installed new headlights yesterday. It’s an auto but still a pleasure to drive.
The 'Mazda' Escort GTs were fantastic. I had the teal green, about a 92, and before that a regular 'Ford' Escort GT of 89 vintage. Actually also a very good car but the later version was superior. I know someone who put over 400k trouble-free miles on another 89 GT, though, so pretty stout cars.
Anyone know where i can find parts for my Miata? Kidding aside, this is truly one of those cars where a lot of the beauty lies in their simplicity. I built up a wrecked one for a Gambler rally a few years back and to date it is still one of the most reliable things i own.
I worked for a Mazda dealership for over 30 years (1977 to 2011), and I went to the Mazda school for these cars. I was guessing stuck rings from the beginning. This vintage Mazda had "low drag rings" in an effort to improve fuel economy. While it did accomplish the intended purpose, this was the the down side. They also were a little slower to warm up on a cold morning. One of our guys made a pretty good side business out of re-ringing B2000 trucks for a local currier company that used a fleet of them. They could get 300,000 miles out of them, but they needed rings because they would be stuck, never worn out. There was also no cylinder wear to speak of, due I am sure to the low tension on the rings.
Thanks, your ending semantically satiated me on the word "Miata".
Thanks for the midweek teardown!
Hey Eric, I used to have a fantasy about asking you for a job. I live in Colorado. Anyway until recently I was a mechanic at a mom and pop shop for three years. I was also a volunteer radio DJ at the community radio station. I got hired as Music Director so I quit wrenching. I'll still watch every video you make and think of what might have been!😂🤣✌❤
That was a simple basic engine. Too bad I didn't get a chance to work on one. Thanks.
The late '80s and early '90s was a good time to work on cars. EFI allowed them to get rid of a lot of the weird vacuum emissions accoutrements from the carburetor era that had just ended. You often didn't need a lot of special tools to diagnose things.
I sometimes wonder if I should have stuck with port injection instead of going direct with my Lemans transplant.
More compression for power and effiecency but another layer of complexity.
It's interesting to see you tear down an engine that you are VERY familiar with. It's obvious you have a totally different attitude and approach. Cool.
Back in the day I bought a 1.6 for 20$ off Craigslist and rebuilt it to replace the perfectly good engine already in my 90’ Miata. 😎Thanks for the memories 😎
I turned "Miata" into a drinking game. I'm lit.
I'm so excited to see my car's exact engine on this stand. The abuse these powerplants will tolerate both stock and boosted is incredible. It's no beast by any means, but it fits the character of the the NA Miatas perfectly.
"I'm not saying Ford is bad, but the mix wasn't great." Volvo shipping with Ford was also a less than ideal pairing. I'm not saying Ford is bad, but I'm sensing a theme here.
The ford/Volvo crossover b525 with all the kung fu noises is maybe the best thing to come from the unholy alliance.
I want to know why ford did so much R&D on how to make paint stick to aluminum all through the 2000s in preparation for the aluminum f150, when they could have just copied Mazdas homework since a) they owned Mazda and b) miata hoods are aluminum and aren’t known for peeling/corroding
@@timothybayliss6680 I have a B5234T and it makes a lot of delightful choo-choo noises
Yes! A Wednesday teardown and I am off work today. Love the mid week teardowns. Thank you Eric!
I have an nb1 with a 1600 engine. Travelled only 35,000km. I pamper the engine with regular servicing and the best oil available. In return I get a great ride !
There is an old trick to try if you believe that you have stuck piston rings and it (can work) but nothing is guaranteed and that is to pour WD-40 into the spark plug holes to where the piston tops are covered in fluid and let it sit and soak for a day and then turn the engine back and forth slowly (not with the starter if the plugs are installed) and let it sit for another 2-3 days checking to make sure the piston tops are covered in fluid and (each day turning the engine back and forth slowly a few times) and after about 3 -4 days suck out the WD-40 if there is any left. WD-40 will dissolve and break up the carbon crusties locking the rings to the pistons and go through into the crankcase and WD-40 mixes well with oil. I would advise doing an oil and filter change after doing this before running the engine for any long period of time like when you plan to drive it.
Apparently, you use carb cleaner first, then the WD-40 which will absorb into the carbon and make it easy to brush off.
I have to do a piston soak on my Nissan 3.5, and from what I've heard/read, Chemtool B12 is the bee's knees for that.
You sure do love Miatas Eric
Ha, this is what happened to my old Suzuki Swift gti when I bought it years ago. Pulled it apart, oil control rings were stuck to the pistons, after removing them had to clean the holes behind them on the piston were full with carbon deposits.
After some further cleaning I slapped it back together (with new rings) and it ran amazing for another 100,00km before selling it for double the price I paid. Early 90’s Japanese engines are amazing
My friend, you are a sick, sick man. And I admire and love you!
If you have any videos of full engine removal from an actual chassis; it would've been so useful for me months ago. But this is also incredibly fun-- I just did this entire job on my miata last week. You make it look easy!
I love me a midweek teardown! Thanks Eric!!
They’re so darn small though . My 92 rx-7 was as small as I could go. Fun car but too tiny for me .
his own engine and we still get to play the "Is is drained?" game!
I had a '91 Ford Probe. It was the best car I ever had. I bought it used in 2003 or so.
I like seeing the non destroyed ones maybe you could do another old cast iron V-8 they never get boring.
I was just thinking about my old job. I think you would really enjoy pulling apart an aircraft piston engine.
Eric's got a lotta broken miatas... (That could be a country tune, lol...)
That sure looks like a simple engine that would be fun to work on. In my opinion, the fun is inversely proportional to the complexity.
Back in the late 1960s, my uncle(who liked to buy and sell cars) had a Corvair that burned oil so bad that you could not see if you followed it. A person bought it and was going to drive from Oklahoma to California in it He went 20 miles before the engine blew up. Also, we had a 1992 Ford Escort with a 1.8 Liter Mazda engine that went 240,000 miles before we got a new car. We did the recommended oil changes, timing belt changes, etc.
Ahh yes - the infamous LWSC (light weight sport crank) as the short-nose 1.6 was dubbed on the mailing list back in the 90s. As I recall, most failures would happen after timing belt replacement, and suspect that the biggest cause was improper torquing of the crank bolt - too loose and things are obviously gonna move, but if you crank it down too much to make things 'tighter', it can stretch and ultimately make them looser, also ending in a chewed up crank.
I’d like to someday get my ‘96 back on the road, but it has terminal cancer from the liquid car dissolver used on the roads in winter here in CT.
Really enjoyed my 95
I recently got a heap of a NA 1.6 with a long nose crank that I'm going to rebuild into a nice weekend driver. I will be watching this video as I open up the engine to see what I suspect might be rod knock. We will see! I bet I'll need parts soon...
Whoa...a midweek teardown special...thanks Eric!
Pretty tough little engine. Another Great Video, Thanks.
Thank you Eric!👍
Having worked on a FWD B6T in a Ford from Australia...uhh I'm glad I haven't had to work on it again.
D: The top loop of the dipstick is still there! I thought they were all broken off!
I may be biased since I’m an 80s kid, but this is the golden age of automotive engines. Older stuff is too antiquated and sacrifices too much due to old technology (old metallurgy, single camshafts, pushrods, carburetors, etc), new stuff is over complicated to try and get inherently dirty engines to be “clean.” If you were to look at a list of top 10 best engines of all time, most of them would be from the 1990s and very early 2000s.
Can confirm when I bought my 1994 Miata it had the oil dipstick loop handle broken off. Somehow one of the easiest dipstick tubes to uninstall/reinstall but one of the worst dipsticks to actually use when it's attached to the engine due to the bends in it. Though my Miata had been messed with in so many weird ways by previous owners I can't be entirely sure they bent it to try to get another 0.3 HP or something dumb 🤷 I tell ya the combination of removed exhaust manifold heatshield and a cold air cone filter without anything to separate it from the hot engine was not the performance bonus the previous owner would've guessed 🙄
It is such a treat to get a 2nd weekly teardown 🙂
Eric, the Miata Guru.
Well done, keep it up! Another nice teardown, glad it went well with good parts to re-use.
When you talked about using cheap motor oil it reminded me when different shops would sell reconditioned motor oil. I had an old Chevy Vega that burnt more oil than gas. I'd buy that reconditioned oil for less than a quarter a quart!
I just love this channel. Such a great attitude and approach to business, and even local to me. Just wish I liked working on foreign cars more, then id probably be a customer weekly, always amazingly blown up things come through my shop.
Sweet! A mid-week bonus - thank you, Eric!
My 1989 323GTX 1.6T had the loose crank bolt and then the damaged keyway issue. The Loctite fix cured that for another 100K miles. Currently my GTX has the 1.8 BPT so no more crank nose worries.
Wait, a mid-week video? Holy crap!
Quite enjoyed the end of this one, especially the S2000 mixed in. Pity those went away
Made my Wednesday complete!
Man that water neck on my old Mazda 323 with the BP05 engine. It got a leak in it and sprayed coolant violently. I sealed it with high temp chemi weld putty and it never leaked again
Watching this made me regret having recently sold my 1992 Eunos (400,000 km and not burning oil)😪to buy an ND.But I love my ND😎
This video is relevant to my interests! Currently working on a 1990 Miata engine to swap in my ‘73 Triumph Spitfire. Picked up the engine and transmission for $250. It was allegedly an oil burner as well. I’m still working on getting it mounted so no idea how bad it will be! Hope it’s just valve seals or something easy, but it’s probably oil control rings…
great vid but also nice recommendations in the description! That Audi v10 really accidentalied the whole thing
Thank you for the mid week teardown. But this engine did not have any carnage.
You definitely have a Miata obsession
Thanks for this teardown! Love your content! Please keep it up!
This was good.
Would love to also see the 16V FSDE 2.0 4 pot motors from the P5 wagons on here if possible.
I drive one still that I bought used in 2012 with 110K+, and now has 198K+ and still going. Yes, despite what some say, they ARE non interference. Ask me how I know... Mine is a tad battered due to living on the streets as one, for many years, I lived in an apartment, now own my house and it does not have a driveway.
Despite it blowing a tad of bluish/grayish smoke for a second or 2 if I've not started it in a day or two, it's fine otherwise. The ONLY issue is the peaky torque/power curve.
That exhaust mani is cool (when the engines not running) 👍
Appreciate the mid-week drop. Nice surprise to see it after a meh day.
Called that one. I figured it was the rings from the moment you said it was an oil burner.
