As a young adult, I would always get up on Saturday mornings, pour myself a bowl of cereal, and sit down for Powerblock TV. Two hours of mechanics going ham. That's why I adore this channel. It brings back the same feeling that I had as a young adult watching that on Saturday morning. Thanks for giving me that blast of nostalgia, Throtl. Very much appreciate it! \m/
I was the same way. So many good shows . My favorite of all time was trucks with Stacey David
Powerblock TV was the move on saturday mornings!
The only difference is, Throtl actually shows all the steps of tearing down and rebuilding the engines.
If you have direct tv there is still new episodes of some of the shows like trucks and two girls garage etc on 281 motor trend. I remember way back when it was the speed channel or network.. and then before that it was something else but I can't remember what it was called .. it's been like over 20 yrs
They should finish my '79 C10 w/ 454 and 4L80e and it'd be just like Powerblock TV 😂
Jedi engine master Quin should get the opportunity to rebuild the S55.
The throttle body has a water jacket for cold climates. Make sure to check those oil squirters, especially on #6 which could be the cause of starvation.
A water jacket for the throttle body? Wow.
@@joeyjoejums Yea i have it as well on my 1993 e36 throttle body for M50 engine- so they been doing it for a while
@@defkon99i was just thinking about this because I’ve done some of the older e30-36s-46s
A lot of F chassis. And man i remember BMW running water in everything. Like the first time i found out they ran coolant thru the computers 🤯
@@kevintejera8478 srs computers wow
Just had a idea: throw this engine in a E46 M3 with the DCT.......
plus Bigger TURBOS BABY!!
@@asmahanumer #MOPWAHBABY
You read a lot of people's mind bro.
E46 M3 with a S55 Swap. That's gonna be a sick of a build
Quinn , I really appreciate the way your explain the parts. I’m novice with car knowledge . You explain it in an easily accessible way .
Quinn's love for all things BMW is infectious (minus the DTM squatted suspension😉). Seeing him building an S55 and making a little drift missile with it would be awesome content for the channel and a chance for the crew to test their fabrication skills on new kind of project
I'm with Ricky "BMW's, don't buy 'em" lmao 🤣
So don't buy the new Supra either then right?🙄
@@eppyzcorrect
@eppyz its a joke big guy
Fkin right. BMW's are made of chinese plastic.
@@eppyz100% because it truly isn’t even a Supra, it’s basically a new Z4. All of the parts throughout the car have the BMW logo on them, nothing Toyota and Supra about the MK5 other than the Toyota and Supra badge.
It should really be called a Zupra.
I still think it is a very slightly bent valve stem on cyl 6. That caused the valve guide to wear and also wore out the valve stem seal letting oil in there causing that weird misfire. Very likely happened when the stock intercooler failed and it ate coolant.
I’d check all the valves and guides when you guys rebuild that thing🍺
Let us know that car drove me and Mike crazy😂
this has to be the only answer.
I think when it went low on oil, the heat built up and dried out those stem Seals. But the lobe on the crankshaft being so bad makes me think that the oil starvation was so bad that it was microwelding when the car stopped. I didn't see him pull the valve stems though.
Such a cool episode! Just when I thought that Quinn couldn't impress me more than I am already, he does this! What a guy! Kudos, man!!!
A 2002 restomod with this motor in it would be special guys. Converted to one large single turbo.
Or a CSL Batmobile would be an awesome build.
I’m not a BMW fan, but I’d love to see this come to fruition.
Thanks Throtl, always fun and educational to watch.
Tricky from England.🏴
Love the 2002 idea!
Rebuild it please. I've learned so much watching this episode. I would love to break down an engine find what's wrong and fix. This is so interesting to me. I'm having to do that now with my wife's 2.4l gdi motor. Timing chain broke so I need to yank it out the car so trust me this is so informative to me. Thanks crew 🫡
I would LOVE to see the rebuild happen. Especially with Quinn's master builder hands on it.
I think the pitting on the internal parts came from sitting for a few months. The engine failed in hands of the previous owner and the repair bill being for probably, replacing the engine long block, the owner left the car sitting until he figured something out. That exhaust valve stayed open when the engine shut off and the moisture creep from there to the internals. Then he just gave it as trade in, hoping for the dealer to not find out about the problem. Then you bought it.
This is the exact scenario I was thinking 💯
As a tech, this sounds about right
Good find, I believe the reason why you are only seeing the issue on part throttle is the vanos timing of the cams. BMW STEP tech here.
Quinn did a great job explaining his thought process while taking the engine apart and diagnosing it! I’m excited to watch you guys build this engine and see what you put it in
Mike essa (with DDE) had oil starvation on similar designed block for the f30 340 motor on cylinder 6. It seems to be a common issue with high revving use, but he did make a fix for it after new cams
water defantly played a part in that pitting rust formed you guys drove it cleaning the lob but damage to the materal was already done from sitting.
@15:21 jegs sells an oil pan taht straddles an engine stand. or you can weld 2 flat bars to the lower beam alllowing you to set a pan across the flat surface of the 2 welded bars.
9:51 1000% agree with Ricky 😂😂😂
nice job taking it apart and getting to the conclusion boyz! Such a shame it was oil starved, now it had to come out and be disassembled etc, just because someone did not check oil lvl enough.
E46 M3 GTR with an S55 would be 🔥🔥🔥🔥
Impressed with the diagnostics and level of detail on this teardown
I would say it was a bad turbo actuator. It was causing excessive turbo lag , under heavy load. When your reduce exhaust flow engine can't push exhaust out fast enough.
Shoutout from Cape Town 🇿🇦, awesome content👌🏻 As a BMW owner it’s amazing to see you guys work in a straight 6🤝🏻
Quinn is awesome. The network should sponsor him for his choice of cable TV show and RUclips channel. Raw talent at its best. I'll always be a student in that class room .
I'm sure the misfires are coming from coolant. There is a leak somewhere. Those air to water intercoolers are notorious for leaking, all brands related.
Seriously, you all could have just passed on this engine and not said a thing. Absolutely trustworthy dudes. Love this channel.
Manley H beam rods , cp pistons and port injection you'll get 1k whp.
9:49 BASED!!!
A good condition S55 with just studs is capable of pretty decent HP. I think since the B58 and S58 have come out, the S55 has taken a back seat in most people's minds because of how easy they make power. With rods and pistons, this S55 is going to be a monster. I'm excited to see what they put this in.
Yeah i also agree with you too yall should rebild the whole engen with more poweron it
Not surprising that the camshaft is bad. I bought a brand new Chevy years ago, it spent 92 days in the shop out of 6 months. Thankfully Texas had a lemon law. The camshaft was bad in it also.
Yes, please rebuild! Love to see it drop into a cool rebuild down the line.
BTW Carbon Buildup is a common issue for S55, where fuel is sprayed directly into the combustion chamber instead of the intake manifold.
These deposits can reduce airflow, performance, and fuel efficiency, and cause rough idle, misfires, and cold start issues.
I wonder if you could use a strong magent to hold the oil catch pan to the engine stand while you drain it. Yeah, Magnets, baby!
Quinn, you got all the tools and shop necessary to fab an engine stand to your standards. Viper casters and a hellcat catch pan. Get to it Brother!!!!!!💯💯💯💯💯
I absolutely the videos of engines I just love how quint explains everything and the videos are so entertaining keep up the good work guys
I really enjoy Quinns enthusiasm. Keep up the great work. Can't wait for the S55 rebuild.
The stick crank hub is the weakness of the s55. I would suggest to get an upgraded hub. They tend to slip once more power is added to the engine.
That’s crazy because I want to buy an F80 and I’m a tech at BMW usually they’re solid motors when left alone…
just going thru replacement of engine on my 115000Km n55 335i spun a bearing and put metal through all the rotating assembly. was all stock so was a surprise is costing me a heap.
Do a big HP DI fuel only build, would love to see that.
rebuild for all the boost and put it in an awd chassis cart thing.
See if cylinder #6 compression piston rings are stuck! #3 on mine got stuck and threw check engine light! Had to replace B30 motor! M->
Did I spy a widebody S15 in the background? New build? Have hopes! Glad you figured out what was wrong with the S55 though. Good to know for those who have that engine!
Not too knowledgeable on BMW's, but if it were me, the possible starvation issue would lead me to at least replace the oil pump or clean/rebuild (I don't know if some are modular or whatever) just to be safe.
You know they make oil pan especially for engine stands right? It goes right over the center & has a channel for the beam so it doesn't move or fall over. Sunex Tools 8300DP so you don't even have to look it up $40.
To me, it seems most likely that it was low on oil or had old oil that wasn't lubricating properly that caused the lifter to wear first and the worn out lifter caused the cam to wear unevenly. From my experience, it's usually the lifters that fail first
Not sure the miles I saw the other video and commented it was the valve shaft worn. It is a wear item and kits are sold. its like 2k for the kit. And 8 hrs labor.
JEGS makes an amazing engine stand tray that fits perfectly!! would recommend
If you rebuild it, change out the OEM crankhub to a 4-pin or 2-pin keyed crankhub! Since, you're already taking it apart and get an upgraded valve cover! Those are the main concerns for the S55 platform
SINGLE TURBO THIS!!
19:55 in Ricky & Quinn Got Beef 🤣 Let Quinn show what the S55 can do plz!
Send it to Daves Auto Center. Theyll figure it out in a half hour, and itll be a cool collab.
Definitely build the motor. I like when you guys mod the motors more heavily over body stuff. Maybe swap that built motor into a base 3 series and make it a sleeper, that would be cool.
Maintenance on ///M Products is so crucial. I loved my e46 M3 back in the day but that performance comes with additional rigor with maintenance. Very unforgiving. Such amazing machines to drive, but do not mess around when it comes to maintenance!
Every time I watch a teardown on a BMW inline 6 I love my 2JZ more and more.
You should find a nice modern classic chassis and slap in a Quinn build S55 weapon. Drift car spec. Bosh ❤
YOU CAN DO IT!!!! REBUILD IT!!!! VROOM VROOM! I agree with Quinn. 🥳🥳🥳
M33 is a fantastic machine, yes rebuild
I say after y’all build the motor you should drop it in Quinn M3. The Ultimate Sleeper and keeping it in house. That what I’ll do 👍🏼
It’s amazing how such a small thing can cause all this mess. Great video!!
Glad the 3 likes was surpassed can’t wait to see it make 1000 to the crank. Don’t know how dependability will be but can’t wait to find out.
Quinn they do make engine stand drain pans
Definitely do a rebuild! haha love how Rickey is a genuine bmw hater lol but i love a Quinn engine teardown/rebuild episode. So much knowledge to be shared!
You guys should really rebuild the s55 engine straight facts 💯
QUINN!!! They do make engine stands with a built in tray holder on the bottom now.
Definitely rebuild it and we'll drop it in my 16 340i. That'd be straight 🔥 👌🏽 💯 🎉
hmm cracked head is possible. if you want to place a pan under engine on engine stand do like i did i built a removable plate up top of the center leg to hold pans onto stand while i am rolling engine over.
Quin needs to rebuild the S55 for big power, then it can be dropped in the Prowler as a straight six is ideal for the narrow chassis.
7.3K as of my LIKE. Let's go boys and girls, WE CAN DO THIS!!!!
I would like to see an in depth “how to” engine rebuild video. Something outside the box for once
2:30 before I get to the end of the video, it's the OEM intercooler. How BMW managed to make that thing so unreliable for a simple function is beyond me. If I'm wrong I'll edit this comment but I'm pretty sure that's exactly the issue.
Edit: 13:00 Dang, I was half right. BMW failed this car with the intercooler but it had already been replaced but the owner(s) really failed this car and ran it low on infrequently changed oil and beat the hell out of it. In retrospect it was a great idea to swap in a motor and send the winner on his way.
Rebuild it into single turbo setup and you'll have something unique and 2jz sounding
Smoked cam lobes on the exhaust also explain all the carbon build up in the head.
Need to put this into a JZA70, for an old school version of the New supra.
Rebuilt it but not stupid power just like400-600 hp and put it in a small car like a Miata or a c5 just some crazy build it will be fun to see
They make engine stand drip trays, very useful
Throtl VIP squad good afternoon Evan Quinn, Mickey Rickie Rick Victor Shawn will Nate Tim big Jeff and the rest of Throtl team awesome tearing down the S54 ❤👍🏽😊
Rebuild it and make as much power as possible!! Let's go!!!
Rebuild it! Then put it in my 2016 F30!!!! Love you guys!!!
Of course you should rebuild it, great content and the final result will be whatever you want it to be a MONSTER
Definitely do it guys!! With love from Tampa FL ❤
This would make a great swap for a restomod project
There is a known issue with the S55 where the exhaust cam isn’t torqued down correctly from factory and it “floats”. It’s usually most notable by a rattling sound on a cold start that goes away.
Could the exhaust cam have just become “loose” towards cylinder 6 which caused it to wear more? A previous fault that has just got worse over time?
My M2 Comp (S55) had it and BMW replaced the cam and carrier under warranty.
That's what I was thinking. Same happened to my f80 but when I inspected the cam lobes they all looked good so I just bought new bolts and reinstalled making sure to torque to the correct spec and it solved it.
Bad rocker with the variable valves not getting enough oil pressure causing the cam to get eaten. Seen in mopar all the time.
I don't even like BMW's but I'll always say yesterday a throtl engine rebuild😅
But BMW says 10k oil changes are fine🙄(People obviously don't check their oil levels in between either)
How many miles are on this engine anyway?
Gottta rebuild it but stick it in a older BMW, E46, E36. 2002, 7 series.
Can we get some info on that silver s15 yall have in the back ground? That would be awesome to see get built
You should build that beautiful engine and again, like what I said before, paint the floor. The floor of the shop. Paint it. It will look cleaner and beautiful. Red or green floor color is good.
I was happy when we were doing the Evo.This is sad.:(
The best channel, love the humbleness and awesome content. ❤ from Australia
You guys should swap the S55 into an E36 chassis!
Yes you guys should rebuild the engine it's been awhile since you guys done an episode like that
Heck yeah! I want to see turbo upgrades and everything
Les gooo!! Rebuild the s55 and show Ricky 🤙😂😂😂😂
instantly i knew it must be something with the tarburator
All Throttle bodies had coolant running through them. I don't remember what year they made it mandatory for manufacturers
I’ll like to see if y’all can put that in an old 1970’s BMW 3.0 CSL😉
It would be awesome to see it with bigger turbos and more horsepower all around
