i have a very small oil leak from one of the bolts that you loosen to clock the hot side of the turbo, the turbo is brand new, however when i first installed it the oil drain line was pretty shitty and oil backed up into the turbo. Now i only drove about 5 miles with it like this, and thats all, the car was smoking pretty good. So now i changed the drain line, and the car doesnt smoke, but there is still a small oil leak from that location, pic below. I did tighten the bolt that its leaking from and the 2 on either side.

I've ran into the same problem.. get a oil restrictor 1/16th, it helps but doesn't fix the problem completely.. I bought my garrett used for 120 bucks, so I justify it that way

I do have an oil restrictor in there, its a -4 line.

Its a brand new turbo, what could be wrong...?

i have a similar problem with my brand new GT series turbo, but on the compressor side the the turbo... very few drops of oil after driving a few miles with boost.

When i drive without boost, it's completely gone.

i also didn't find anything to stop it... if soemeone finds something i'am also glad to hear some ideas.

ya it seems very minimal, i dont mind it really, but as long as its ok....or is this a sign of problems to come?

My garrett one leaked around the same area and I paniced at the beggining, was like very little and hard to notice. It eventually stopped after couple of starts.

Give it some time, both of my new turbos did it then stopped after they got hot a couple times and cooled down.

The seals are actually piston rings. Once they go, you're usally SoL. Its a mechnical seal that covers 99% of the space, which about 10-30psi worth of oil pushing on it. Any damage to them and they will leak. Fixing it isn't that bad, you need a good rebuild kit, remove everthing (marking the spot the wheel/nut/shaft all fit each other) and put the new rings on. Usually though only the seasoned or professionals should do it.

it seems like the leak has stopped, i put a clean piece of cardboard under the car overnight, and not a drop.

You said 10-30 psi of oil pushing on it? I get 87 psi at idle on cold, and 80+ at WOT....

Once warmed up, your oil pressure will drop. Depending on your setup, engine and oil pump you should see between 10 and 30 psi when idle and about 60-80 psi when over 3000RPM. Many here state that oil pressure increases every 1000RPM by a certain number, can't remember but if you search it you'll find it on one of the posts.

You might want to fit an oil pressure gauge, also the reading from where the OEM pressure switch fits seems to be lower than from where the oil filter is as I found my self when I fixed the gauge to a sandwich plate instead of T'd into the pressure switch place.

I just finished clocking my turbo so it angles straight down.. so in a few minutes i'll know if that was the problem with mine.

also something else to consider is crank case pressure.. if it's too high (no ventilation) it will cause pressure in the oil pan.. which in turn pressurizes the drain line and results in backing up oil in the turbo

jDMJeRk

excessive crank case pressure can cause a turbo to leak like that as well

Your drain looks decent but is it above the oil level?

srmofo

did you clean the oil out of the turbo after you fixed the drain tube issue? that could just be residual oil

Sorry to raise the dead but did anyone find a fix? Or did it go away after more startups like for the others?
