I must say, Peter is the happiest person I have ever seen. The man always has a smile. Cannot picture him angry or upset.
Stay that way Peter. People like that are rare these days❤️
I think the oil leak around the pan is warpage caused by welding that oil port onto it.
full agree thats my thought too!
I don't.
I think the welded corner is warped and pressing on the block/gasket so it seals properly. The rest will not seat, there a slight gap or less pressure, hence the leak.
That's just a guess but it matches the symptoms.
I wonder if that location is also an issue, the turbo might be backing up with oil. He should have it enter the side of the oil pan.
Flatten it on a piece of granite or glass
Peter just needs to tap the oil pan with his hammer a few times, should be leak free afterwards
We need merch with a hammer on it.
Hammers don't work for everything, man!😮🤯🤔🤯🤯😱😱🤯😮
*while driving - obviously won't work unless in motion, that's on page 2 of the directions
@@craigmorgan4676 you are obviously a man who doesn't own the right hammer. 😀
Pete'll Fix It! 🔨👷
Peter is a great addition to the channel. As always, well done.
couldn't agree more
Love how this channel actually talks and explains things about all of the cars he works on, amazing channel, great job Alex, and Peter seems like a stand up dude you guys work great together! Keep it up legit street cars! And deffinaly the Trans Am is bad ass! Throw the t-56 back in it and record it for us!
That's because this is a car guy making RUclips videos and not a RUclipsr making car videos.
Been subed since way before he quit his "real" job, and it's still the same great content!
Alex you are easily the most entreating automotive youtuber out there, its always a pleasure watching your videos
Just an all around great guy. Easy going, smart, industrious . . . mechanical, hard worker, personable, . . . am I gushing?
@@leonarddaneman810 you forgot handsome
@@byron1dagg80 I was 'gushing' without being 'gay' . . . okay? Alex is just a great guy, was probably a great boss, even though very young for his position . . . Peter is also great.
@@byron1dagg80 I knew you were gay from the first comment.
Now pull apart the rest of the cold side and hot side and check the intercooler and charge pipes for extra oil inside. It will tell you if there was any extra oil blowing past the turbo when hot. Also make sure you have enough crank case ventilation. Too much crank case pressure could blow oil back into the intake side of the intake system.
This!
The aluminum pan may have warped when you welded the bung. Do you have a spare block? Get a new pan and weld a new bung but bolt the pan to a block with no gasket before you do. Also, stitch weld the bung so you don't put a bunch of heat into the pan.
The puff of smoke could be the turbo oil drain backing up. When you shut the car off, the oil doesn't drain fast enough and a small amount backs up and since there's no positive pressure on the compressor side of the seal, it leaks into the compressor housing. It doesn't smoke when it's running because there's positive pressure in the compressor housing. I know you said the drain only needs to be lower than the turbo, but I've seen issues with oil backing up due to the feed being pressurized. It's possible for oil to feed into the turbo faster than gravity can drain it. Whatever it is... It's in the turbo, not the engine.
Of course, I could be completely wrong on both, but just spit-balling based on my own personal experience.
once the engine shuts off, there is no longer oil coming from the feed, so the drain just drains into the pan. i don't see how it would back up and overflow into the compressor housing. there was no evidence of oil on the compressor side. he never showed the piping, but i highly doubt that's it. that turbo looked pretty healthy.
Agree. The 15-20 minute is MAX temp as it heat-soaks, then after an hour, cools and gravity drains.
I absolutely love this car. I'm a Camaro guy, but I love the birds too. I absolutely love the way you built it and kept it looking original inside and out and you didn't hack it or do anything to ruin it. This car is a perfectly built street car that has working ac and a stereo and ttops. Just awesome man. Never get rid of it no matter what.
I'm a Ford guy and I think it's cool too. My car also looks almost factory stock from the outside and the interior changes are all hidden. The only clue is the larger exhaust tips...
@@nicholasvinen what car do you have? I'd love to get a mental image of your Ford. (I almost said hotrod instead of Ford.....I'm so glad I didn't!!)
I think the trans am is hideous. Way to busy. And a turbo ls is so played out.
But back when Alex built it it was new stuff and he was pioneering on a budget which is very admirable.
Also just so i don't sound like a total hater the wheels the white with black leather... all his mods are very tasteful and make the car look much better.
Its definitely a legit street car.
But its butt ugly lol
@@kylemcweeny878 OK, fair enough. 👍🏻
Peters reaction literally made my day watching this, pure enjoyment!
I'm with you on the oil puff being the turbo leaking. My Audi TT did the same thing and would only do it when it was warmed up. The clearances open up when the turbo warms up. Plus theres no oil in the turbo on a cold start. It all drains back into the oil pan. If it was a manual it would probably do it when you shifted gears. For the oil leak take the pan off and throw the gasket away and use RTV on it. Hey if it good enough for Mercedes. On that note, WHY HAVENT YOU CHANGED THE RADIO YET?? lol You cant be a legit street car without having bluetooth.
Let it get to temp with the turbo off and the turbo feed capped. Let it sit and see if it does it after the 15 minute window. Will let you know internal or turbo problem. Also let me know if you need DSM parts. I am located in CT and have quite a lot of stuff.
Good call. That would confirm turbo issue
Eliminate possibilities.
Great suggestion
Are you running a catch can? New build with high pressure could be recycling oil through the pcv and buning it once cycled through.
It sounds PCV related to me. Hot spot in the engine causes some vapors to condense? Although most boosted guys remove PCV and vent to atmosphere. Interesting car.
Awesome, the TA was one of main reasons I began following you, hopefully one day I can bring my 2000 Arctic White Ws6 m6 out that way from Iowa. Can’t wait to see the rebuild.
This video resonates so deeply with me! Not only was the WS6 also my high school dream car, but I also have your same "LSC" philosophy with my with my ATS-V. A 10-second daily driver (winter too!). Hopefully our cars will find each other on the Kennedy, Addams or the Edens some day soon!
Love the passion for a car you’ve had so long. My rally car is something similar in that I bought it new 22 years ago as my wife’s daily car. There isn’t a original bit in it today with 3 times the horse power etc. you really get to know the car. I know every nut and bolt. Loving the videos.
Great job as always. You have quickly become one of my favorites to watch with fun cars, entertaining personality from you and guests, and sharing tons of knowledge. Keep it up!
You can’t fake that kind of joy! Love the laughter and giant grins. Very cool car, sir. If you’d like, I’m only 3 hours away and promise to drive it for you if you store it here.
My friend had a black on black WS6 in high school and it's always been my dream car. It's the reason I got a Grand Am GT in high school so I could pretend I was driving a "real Pontiac", which it was not, but it did have those cool orange dash lights. 😆One day I hope I can get into a WS6, in the meantime I'll live through Alex 🤣
I would say the oil seal on the turbo is most likely. Have them look carefully at the seals if you send it in. If they are double lipped seals I would guess the inner lip is cut. Can’t wait for the update on the new turbo!
Turbochargers don't use lip seals, they wouldn't last five minutes with the heat and RPM. Instead they use labyrinth seals.
20 likes (as of this post) on the "rubber seals" in a turbo... c'mon, people! most oil burning issues in a turbo system come from inadequate drains, not "seals" which are actually like piston rings...
I think it could be the thrust bearing + oil seal (probably looks a bit like a mini piston ring) on the turbo axel in the bearing block of the turbo. That's where the exhaust gasses might pull some hot thin oil into the turbine housing and out the exhaust.
expanding on that, the "sweet spot" temperature thing could be because of different thermal expansion rates. When "cold" it holds due to thick oil and non-expanded casing/seals/etc. When "hot", you have fully expanded shaft/seals/casing. The in-between may be when the turbine housing is outpacing the shaft /oil seal + the already running temp oil viscosity.
I agree. Also didn't see a restrictor in the oil feed line, that would overpressure the seal and make the problem worse.
Hmm. Well this is my troubleshooting brain thinking about this blue smoke issue. A few questions. What is the block made of, cast iron, aluminum, or billet? If there a sleeved cylinder? Are they all sleeved and if so what is the sleeve made of compared to the block? What material are the piston rings made of? What was the clearance between cylinder wall and piston rings? Could there be an anomaly in one cylinder of oil getting past a ring only after it heats up and the oil gets less viscous from a full heat cycle? Maybe the cylinder wall expands just enough to let oil get past a ring during these conditions only? Definitely curious to figure this one out. I might be completely off track but I remember my uncle who used to race sprint cars not liking the idea of using sleeved blocks, but that was before the LS engines came out and sleeving in drag applications was common.
@@chevyracerzx6 What you're suggesting would be if it smoked while running. It's odd for blowby to induce oil burn on start -up - hence why valve seals were already ruled out. Blow by would also host a lot of other notable problems with a boosted/ 1000hp application - such as noticeable pressure out of the valve covers as well as oil washing/dilution with gas pushing through the rings.
The only other way of oil getting in the top end on startup would be through the turbo. Either by it seeping into the compressor housing, burning in turbine housing as suggested by the OP comment, or by oil return problems.
God DAYUM y'alls a bunch of real thinkers!! Hat's off to ya!!
Your trans am is super clean.. my trans am also has a bit of play on the steering wheel.
best part of the video, looking at how you have your equilizer set up on the stereo. Exactly how I had mine back in the day. Made me smile.
Loved this video bro, especially Peter's big smile on his face when he got to ride in it! LOL
Good to see the car back on the channel! I'm sure you'll get it dialed in
You can tell how much you love the car by how you were able to notice such a small plume of smoke that happens so infrequently. I can relate, I can instantly tell a difference or feel a difference in my cars
Sweet car I remember seeing it around the neighborhood. I went to Ebinger with Ornella. So great to see local people successful and happy. Awesome channel I just subscribed.
I sold my IROC-Z several years ago but this makes me want to get something to work on again.
All the best,
Kent Davies
The Trans Am Is so beautiful, great video as always!
Glad to see some T/A content again Alex. That turbo and torque convertor combo builds torque like a locomotive..LOL.
Stoked for the TA update! Also love T-tops!
Currently in the slow restoration phase with my 94 Lightning. Got it when I was 16 in '04 and had it ever since. I have similar goals in mind as you have with your Trans Am, gives me a bad itch to scratch!
Ok people why is it puffing blue smoke? What do you think about the oil leak too?
Turbo seal
Do you have a oil catch can? Time for new turbo seals
@@rajeshcharan2803 agree. Oil control rings, stem seals or turbo seal. Possible odd egr issue or catch can reflux. added....oil control ring gap directly open to compression ring gap possible. I would run it as is and deal later if it gets worse.
Oil leak is due to warped oil pan when you welded that bung.
Leave turbo off, remove y pipe to headers, start engine and let it warm up, than let it sit like you said for 10-15 mins, than watch the exhaust come out of both banks and see which side the smoke comes from. It will narrow it down for you if its just one side. If no smoke than it was the turbo.
I’m thinking that the puff of smoke could be happening because when the oil completely warms up, it gets thinner and it can leak through more places… maybe once it’s warm it takes 15-20 minutes to leak into a certain spot and then when you start it back up in that time frame it will burn it but if you don’t start it up In That time frame (start too soon) it will not have leaked yet or (start too long after) it’s not as easy to burn the oil because it’s not all clumped up in one spot or the engine isn’t still hot enough to burn the oil as easily… only thing I can think of!
I have no idea on the puff of smoke, but I love your TA. I've owned fourth gen Firebirds for 20 years and absolutely love them. Always a great day when you post a new video on this car.
I know what you mean when you say , " you cant punch it on a turn , only a strait away ". Scary shit . I have a 2002 4th gen camaro. It came with an ls6 block and a ls6 intake. Love your Trans AM. Wish my car sounded just like it. Wow Wee.
Detroit Speed offers a sick upgraded rack for these cars now. I plan on going that route.
Hi! I have owned a 1999 Trans Am WS6. Nice car👍😍
Greetings from Sweden🇸🇪
Love 4th Gen TAs. Want to get a 30th Anniversary when I retire. Has to be a 6 speed manual. Would settle for a Trans Am Firehawk. On your car I think the issue is the turbocharger seals.
I'd replace the oil pan to start. Especially since you welded that bung on there and all the heat the motor is generating could cause a slight warping of the pan! Also as for the RTV they make a high temp which I'm guessing you used but they also make a oil resistant one as well thats better oil pans! Just food for thought bro! Keep up the great work🔥
By 4:39 I'm putting my money on one question: After welding on that pan, did you straightedge all mounting points on it?
As to the smoke... where in the intake/combustion/exhaust cycle could a source of oil drain in after being heated because the oil was now thin enough to reach that area whereupon gravity takes over and pulls it into the cycle?
I think your on to something 🤔
A cracked oil ring, crushed valve seal or excessive valve guide wear or crack. Turbo oil seals do weird things too. My son and I had a couple of GN's I used to race.
@@aphil4581 Nope, oil isn’t properly draining
Absolutely LOVED the return of the TA! Keep it coming!!
I love the return of the Trans Am I am slowly working on my 01 Firebird and it great to see someone with as much love as I have for the Old Birds.
Love your content Alex, and I don't fix cars, nor do i want to, but your content and delivery is very entertaining, something I look forward to on a Sunday morning here in Australia. Pete is a great addition.
I've been waiting for this content and I love it! Awesome video and I'm looking forward to more trans am videos!
i know its not the usual video for you but a video on the history of your trans am would be awesome! keep up the good work man, love the videos.
I'm agreeing with a couple of the replies about the turbo. But also double check your PVC valve system too. I'm sure you've upgraded it when added the turbo. Years ago my stock 02 Yukon XL Denali 6.0 had that problem, found a bulletin on that issue. I put a new pvc valve in & that cured it. BTW Love your content, I've been watching your channel for a few years now & really enjoy your videos. I'm a Chicago area automotive nut too all GM!! Keep up the great work.
I feel like I know so little about this car. Maybe from before I found your channel. Excited to learn about it.
Loved this video. I miss my 2002 Camaro SS 6 speed. I hope you keep publishing these refresh videos of the TA. About the TA oil smoke…could it be some kind of Turbo blow by? Maybe install a catch can? Keep up the great work!!
Love this car and the trim this was one of my teenage dream car thanks for bring it back on the channel
Glad to see the T/A return! Still love those cars. I remember always getting smoked in my fox body by the WS6's
and SS Camaro's.
AP, congratulations on 750k subs. Your 3/4 there. C’mon people, a million is doable. Can’t wait to see it happen. Keep up the good work AP

I'm right there with ya on 20+ years of ownership. I've had my 87 Cutlass Ciera S coupe since March 17, 1998. Bought her when I was 16. I know her in and out. She still looks great too. Only one like it in NW OH, hell, maybe all of OH, lol.
That’s a good one Alex. I look forward to seeing what you find! Great that your film time now Keep the content coming!!
A friend of mine sent me one of your videos recently and since then I've been binge watching your content. Awesome channel man it's quickly becoming my favorite. Thanks for the amazing videos. Keep em coming!
(Also I noticed in the beginning of the video you smoked an srt4 at the drag strip....that's what I drive.......I love all cars (literally) but they came out when I was I high school and ive always wanted one I finally can afford a nice clean one....quick cars! I'm sure I'll get roasted in the comments now but whatever! 😆 Cool to see one in your video).
The Trans Am is so awesome! Glad it’s back on the channel. (And I’d vote for the CTS-V wagon, hands down.)
I’ve been waiting for this car to come back for quite some time Alex. As a 4th gen owner, this is the car that made me subscribe.
My money is the front main seal (oil leak) They need to be centered with the HB before they’re tightened down to 18ft#. I used amazons cheap dye kit when I put too much positive pressure in my crankcase 🫠. Rear main was a PITA on 4 jack stands.
👍 on the oil less. Heard good things. Looking at two CTR3081E-5858. Good luck with the build y’all!
I am a Trans Am guy myself. I kind of wish mine was turbo'd. Mine is just an LS1/6 speed with a cam and heads. It does however induce similar smiles on the faces of everyone in the seats. These are what modern classics should do. Produce smiles, memories, and conversations almost everywhere it goes. I bought mine to be fun on Friday and to startle people in the parking lot. I went for the 6 speed as it is a dying breed of us out there that can row through the gears. Awesome Video, Thanks for the reminder. I am going to start it up when i get home, just to scare the neighbors and rattle some windows. 😉
I love my Trans Am. Glad to see you driving and fixing yours again.
Love all your videos. I am inspired to try to make my 07 accord faster that factory. I know little about it but want to get into it as things break or wear out. Always been my goal to do my own work on my car to save me money for the fun stuff
Alex (FYI) RE: time mark 21:10 - I put in an aftermarket solid mount (replacing my Bird's "rag joint") after replacing my steering rack too. Like yours, my car's rag joint looked perfect, but WOW (!) that solid mount made a big difference. It is worth considering if you still are unhappy after you replace the steering rack and it was very cost effective. : )
I think you need to send your WS6 to me to diagnose your oil leak. I should have it figured out for you in a couple of months!! You don't drive the car very much anyway so you wont miss it!! Great channel Alex and your wing man Peter!! Very enjoyable!!! Cheers from Canada!
Hi Alex
My focus ST 5 pot used to do the same. Nothing from cold and only certain times when warmed up and left. It was valve seals after all
Alex. You are legendary, no more no less (actually I lied you are more my guy but don't tell anybody) engaging doesn't even justify your content. Keep going fella!
Sick TA! Really looking forward to more of that fox body as well! Can't believe im saying that because im such a third gen camaro guy but I really wanna see that fox get all cleaned up and detailed.
The look on Peters face while you pound on the pedal- priceless! Or is it that Peter knows where the real leak is? Hmmmmm Great show and sorry I missed you at the car show on Sunday in Eddison Park, dam VID got me. Any plans on a video covering that?
Great content. Love seeing content on the Trans Am.
The Phoenix returns..👌👍👏 Hope the issue gets sorted & the car becomes as close to 100% fixed as possible...
Fantastic video. Great work on these beautiful cars.
My turbo civic did the oil thing, turned out to be a seized ring in the ringland. After it warmed up and after a bit of a cool down before a more warm start would let enough heat in the piston to expand the ringland enough to release the ring. Then no more smoke. But I rebuilt in with new pistons and permanently fixed it.
I just bought my first TA!!! It's almost impossible to beat the looks!
The oil smoke is most likely the turbo or the PCV system when it cools the oil puddles up, and then gets sucked up when the engine spins up.
as for the oil leak sounds like your getting positive pressure in the crankcase , due to weak rings ,hopefully its just a warped pan, or maybe an anomaly with the turbo giving excessive boast at start up
Looking forward to seeing what the issue is with the TA. While I love my BMWs, I am also a big GM fan, and a Pontiac fan in particular. I still want an 04-06 GTO someday.
hell yeah, trans am is back. the first reason i subbed to this channel. pump for the merch too!
I'm a car guy, but not a mechanic guy (I tried, but I failed), so I'd love to be able to give you an idea about the issue, but I can't. That said, I can say I love your T/A and love the idea of modding it, while keeping it street worthy.
breakup when coming into boost can also be spark blowout. i know a lot of higher hp cars use brisk silver plugs which are frequently changed every 3k miles or so the gap starts to widen and you start experiencing blowout. some bigger turbo builds will use stage 2 cooler plugs with a 0.025 gap to or pro mods using down to a .015 gap which is really incredible!
I have worked in my driveway on my back for decades working vehicles.
But I have slowly started to take care just work on my own vehicles if I can & if not it goes to a local shop now. Be safe
I can't remember an episode solely about the TA , very nice to see you giving love to your OG legit streetcar 😊👍🏻
Re puff of smoke I would start with engine breather system coz quick enough to do. Failing that it could be turbo seals, looking forward to hearing the diagnosis. Love the channel, what ever happened to the F150?
Same thought here: something to do with the engine crankcase vent system.
I've had my trans am for 17 years and it's been turbo for 13 year's. Watching your video made me feel like i was watching a video of me 🤣
It's probably been mentioned already, but if you're not running a Turbo Timer on this system that could be where that smoke is coming from. The oil, blah blah blah, you probably already know lol. Love this these videos!!
Woaw, this car is LegitStreetCar of LegitStreetcar, the channel, meanwhile the teammascot.
It deserves only the best of the best for sure!
How did a rearwheel drive ever get 9 second times with full interior? 😅
I can only say, bravo! 😄
Disconnect the PCV and see if resolves the smoke issue. You can also measure your crankcase preesure/vacuum under boost as well to see how much blowby is building up in the crankcase as well. There are a lot of articles of people installing crankcase vacuum pumps to scavenge the excessive gasses and add horsepower as well.
Peters joyful face under boost...
Priceless.
Alex this is my fav car of yours! Thanks for finally doing a video on it!!!
Wondering if the turbo is good, you may need to look at your valley cover. Thats assuming you pull pcv from that? The LS6 covers is what I always used with newer valve covers.
Alex, LOVE all of your vehicles and V8 content!!! Long live the burbling V8!!👍
Gm oil pan gaskets never work. At the dealership we always always used tribond or grey rtv engine sealer for any oil pan or diff cover. Did u make sure the front engine cover is actually flush with the engine block? Gm has a special tool to center it front seal and keep the engine block and front cover in alignment so the front cover is level with the block sealing surface.
Alex most likely is a slow closing valve witch might be ore mature valve spring ware or some stiction issue on that particular valve an inspection of the valve steem would ultimately tell you what you want to know little cfoam might clear it up since its most likely not heavy soot in there
Go back and watch the part right b4 you did the burnout and you will see a slight bit of smoke when you get into boost. Check and see if you are getting a bit of blow by. It could be crankcase pressure building up under boost. This is why you always run a catch can on boosted applications. It help prevent that from happening.
I love how thorough Alex can be with his cars! There are times he picks up on things that often go unnoticed, and it really shows with the quality of his cars!
Also Alex if you ever want to take in an inexperienced deck hand, give me a call! Hahah
Finally a fucking Trans Am video! Also finally Trans am merch! I was shocked that you didn’t make not a single piece of merch with the Trans am at the start. Now I’ll be buying! That car is the main reason I followed a longgg time ago! This is the CONTENT I’ve been waiting for! Instantly thumbs up from my ass! From my WS6 to yours my friend
Great content!! The best my bud Alex
If you have forged Pistons normally they seal up once warm . If cold oil could slip thru until pistons heat up
Found this channel after looking for idea videos for the 98 Camaro I just picked up. Crazy you’re in Illinois as well. Any recommendations on shops to rebuild a T56? 5th gear hasn’t been happy since I picked it up
if not v.s.seals and not rings...i would have to go with residual oil in the ring lands. something that will come to light when a thinner oil is used in a high performance engine. to add...make sure the cc ventilation system is up to par with it's ability to purge the engine.
I had a similar issue, only known to me because i know my car so well. My issues where with the rings, heating and cooling causing a small amount of gap and causing a tiny amount of blow -by under the right ( or wrong ) conditions, depending which way you look at it. When i rebuilt the ls years later used a bigger ring gap and never had the issue again ( also boosted Ls) I don't think it's anything to worry about personally. Just my experience
