Thx for the knowledge share. I just watched another dudes video where hes doing a rebuild. While the spray paint job is excellent, he failed to inspect the piston rings and during a zoom in of the turbo, the shaft in that turbo was rounded.
A lot of good info in the video. Thanks. Have you ever heard of a turbo failing due to poor drain even after the drain was fixed? I think this has happened to me, even after fixing the drain issue ( ran it like that for a cpl thousand miles ) the turbo is now still smoking. cheers
Great vid, I like when you zoom in on parts and not just explain! I've one question, is it possible for the drain to partialy block on a high km diesel?
I never thought that adding a exhaust brake would push oil out of the turbo and into the intake. Not much in the intercooler tubes but oil is on the intake temp sensor and Manifold Air Pressure sensor. 🤷♂️ Would could new seals improve the situation. 2001 Dodge Cummins H O. Stock truck except for exhaust brake.
I have a turbo there is so much clearance on the shaft when I shake it from the left to the right, and is making the generator short oil, the generator was just overhaul Q. Can clearance on the shaft affects the shortage of oil and no trace of oil from the intake
My 335i smokes when holding a steady rpm say 1500 to 2000 smokes when driving too not always usually on decel. If I rev the engine in neutral it will also smoke. replaced valve cover, flapper valve, rb pcv, does have a little bit of siren noise I am fbo minus intercooler running stage 2 mhd.
The compressed air can leak into the crank case through the seals but it’s hard to test that, because a boost leak test pressurizes the system but the air can leak fast the valves, front piston ring, or the crank case vent. The gap between the piston ring and wall of the piston ring groove should be .0025”, if larger than the seal or groove is worn.
Hello. Am a fun mechanic and really interested in your vids. I have this VNT turbo off my 520d. Its a garret GT1752V [.46] . Is there some way to get more pumping from it by upgrading?
What's your opinion on turbo size for a 4.6 2v Ford, only looking to run 10psi, and it needs to be a small single turbo, not looking for high rpm numbers but wanted best sound and low end
I opened my intake on 2014 ram cummins and it was a mixture of soot and oil alike, while previous times it was just dry soot... Is this leaking oil turbo? And Intercooler pipes are oily from inside. Thank you for very informative videos
Brand New 0 miles Bank 1 F21BI Franken Turbo leaks right out the V-Band Clamp....being told this is a crankcase pressure issue by Doug because Turbos don't leak like that....I had no crankcase pressure issues before installing these and have an upgraded pcv valve and low side OCC.....also I noticed the blades was kinda stuck and wouldn't spin freely when pulled out the box....after a lil pressure from my finger it became free. I don't understand why. Any input would be greatly appreciated.
Great info. I've got a 2016 Deutz TD 2.9 with only 1033 hrs. The turbo is passing oil until the engine has run for about 2 minutes. No oil blowby and drain is stock. Is it possible the seal are bad already?
What about if you had over 100 pounds oil pressure journal bearing tubro and you didn’t catch it in time shall you rebuild the tubro j think my tubros smoke when I start the car when it warms up the smoke goes away but the smoke comes back after 10 pounds of boost I got -10 oil drain going to timing chain cover for ea turbo and I change the oil pump to regular pump from a high volume higher pressure my question is do you think I waited too long to fix the oil problem and I were out the seals ?
Oil in the intercooler is caused by oil leaking past the turbo front piston ring or from the crack case vent valve being bad (commonly called ccv or pcv). Sometimes people block off the crank case vent which is a huge mistake, this causes the crank case to pressurize which won’t allow oil to drain properly from the turbo, which forces it out the front and rear seal of the turbo. If the ccv goes bad, the turbo can suck oil out of the engine into the intercooler, often people use an oil catch can which will avoid this issue. Its very common that people use a -10an fitting that is too small (10-12mm) which will not drain fast enough, as a result oil is backed up into the cartridge and forced out the front and rear seals of the turbo. I machine the -10an fittings to 5/8 or about 15.8 mm to fix this problem.
I have a Vauxhall astra 1.4 turbo 2011. My turbo was completely shot so I bought a reconditioned unit with like 30days warranty (im an idiot I know) and it has since started smoking from the exhaust but not wailing like my previous turbo did. have changed the pcv system, the solenoid, tested the wastegate actuator, and everything in between, litterally everything in between. Getting code Po299 turbo underboost, it only smokes when I accelerate hard but only around 3k revs and around 60mph and above or going up hills. Does not smoke at low speeds. I have changed the catalyic converter aswell and still have the issue. You reckon my turbo seals are failing? :(
Sounds like you may have a boost leak. If that causes vacuum in the intake at times it’ll suck oil out the turbo. Turbo air intakes need to be at atmospheric or boost pressure, vacuum conditions cause leaks.
@@Nemesis-yn5wv Thanks man for responding. It turned out that my PCV valve had gone missing, causing a shit ton of carbon buildup. Had it all cleaned and the underboost vanished.
Hey trubolab am having a issue with my 2009 335xi am getting smoke from my right exhaust when the car is under boost do you have and ideas as the what causes that issue?
i have had 2 s400 borg warner turbos wear the trust bearing .the first one blew oil out the intake side and the 2nd one blew oil out the exhaust side. the 2nd one only had about 45 miles on it. ive put new feed line and discharge oil lines on . new air filters and checked all the piping.i also have made sure the engines vent tube is ciaer and clean. both turbos had the 270 thrust bearing in . i have just rebuilt the 2nd turbo with a 360 thrust bearing and am going to try it. i did see waer on the exhaust side oil piston ring. mine runs 2 of them. any idea what is causing this? i am beginning to think it is bad thrust bearings from borg warner.
Many thing can make a turbo leak. In your case excessive oil pressure or excess blow by could cause that. Also is the oil return line a large enough diameter for the oil flow rate?
@@turbolabamerica I replaced the passenger side head gasket with a nice felpro on 6.0 vortech (Chevy) with a Borg Warner S475 and I noticed a little crank case pressure out of the catch can before. Now it puts out so much it’s like a coal powered locomotive. Thinking I might have bad seals in my turbo? 🤔
Hi I think my turbo has blown, i live in the uk do you have WhatsApp or a email address so i can send you pics thank you here in the uk it is 8:03pm thanks

Q. Can clearance on the shaft affects the shortage of oil and no trace of oil from the intake
You got my vote of confidence. Thanks
your the man, thanks for the tips!
Brilliant detail. Thankyou.
thanks for the turbo class!
I thank you for this education--- I am now going to remove my KKK from 924 Turbo to see why its smoking ALL the time...
Great video. Thank you.
Thanks man
See I got the same issue, but I can’t fucking find a replacement anywhere😂 I have an 18 focus st and all I can find is for a 6.0
Thanks.

Turbos my friend
And get yourself a Intercooler ASAP
Will you always see visible signs of a leaking turbo? That is can sometimes it leak internally, without any oil on the outer housings
The compressed air can leak into the crank case through the seals but it’s hard to test that, because a boost leak test pressurizes the system but the air can leak fast the valves, front piston ring, or the crank case vent. The gap between the piston ring and wall of the piston ring groove should be .0025”, if larger than the seal or groove is worn.
You couldn't turn down a bushing or insert
How do I send in my turbos for rebuild and upgrade.
Hello. Am a fun mechanic and really interested in your vids. I have this VNT turbo off my 520d. Its a garret GT1752V [.46] . Is there some way to get more pumping from it by upgrading?
Awesome :) Thanks for your efforts :)
Can you give me a price on a used VF36 TiAl shaft?
Or TD05 TiAl shaft, forward and reverse rotation :)
Schalk Jansen that’s something I don’t have
awesome video
What's your opinion on turbo size for a 4.6 2v Ford, only looking to run 10psi, and it needs to be a small single turbo, not looking for high rpm numbers but wanted best sound and low end
Oversize the seals or make duplex setups no need to buy a new shaft.
I opened my intake on 2014 ram cummins and it was a mixture of soot and oil alike, while previous times it was just dry soot... Is this leaking oil turbo? And Intercooler pipes are oily from inside.

They are not a true seal in the sense people think .
Where can I contact you to get a price on rebuilding n54 turbos ?
Hi, you already have through facebook, thanks.
Also, Where can I find a rebuild kit for a Deutz 4134936 turbo
Great info. I've got a 2016 Deutz TD 2.9 with only 1033 hrs. The turbo is passing oil until the engine has run for about 2 minutes. No oil blowby and drain is stock. Is it possible the seal are bad already?
How high do the turbo temps usually get on a road racing car? I’m worried my seals went bad from excessive heat.
Price to upgrade an he341?
What about if you had over 100 pounds oil pressure journal bearing tubro and you didn’t catch it in time shall you rebuild the tubro j think my tubros smoke when I start the car when it warms up the smoke goes away but the smoke comes back after 10 pounds of boost I got -10 oil drain going to timing chain cover for ea turbo and I change the oil pump to regular pump from a high volume higher pressure my question is do you think I waited too long to fix the oil problem and I were out the seals ?
Excess oil pressure will cause leaks.
I'm trying to match the hot side of a turbo to a 6 liter ls Chevrolet engine. I don't know what I need, can you explain to me how to get that right.
Hey I need an oem MHI TD04L shaft. Could I request one with the purchase of a rebuild kit for a wrx on the TurboLabsofAmerica website?
Quick question what would cause oil in the intercooler? I will really appreciate if you can help me out with that.
Thanks

help! My turbo is smoking, not from the tailpipe, the turbo itself emitting smoke,
what is most likely the issue, i threw a p0011 a week prior

Hey trubolab am having a issue with my 2009 335xi am getting smoke from my right exhaust when the car is under boost do you have and ideas as the what causes that issue?
And got oil on the intake
whats your adress so i can ship you my turbo
My triton diesel smokes at idle but when i drive it its fine is my turbo bad
Check if the intake is under vacuum at idle. Vacuum sucks oil out the turbo.

The piston rings can wear out from the movement of the rotating assembly when the thrust bearing goes bad.
