Mobile 1 oil?

[stevesnj]

Valve stem seals maybe?

[Detroiter]

When installing the turbo kit did you prime the turbo? (pull the fuel pump relay and turn it over a few times to get oil flowing through the turbo) I'm not sure if there are any instructions that state this but you should ALWAYS prime any new turbo before running the motor.

If you did not prime it. My bet is that it could be one of two things. 1 it's just the new exhaust piping on the car, it will smoke a bit some times. 2 it's the seals on the turbo are toast because of not properly priming it. Hopefully it's the 1st one.

Took to a pro tuner and they did compression check, leak down test, checked the valve seals. Everything is good on the motor side. As a last resort they ask what oil I'm running and they say a lot of Subi motors have problems with mobile 1. Fill with motul race oil and no smoke.



Just wondering if anyone else has cone across this problem?

You should look beyond the numbers on the bottle when comparing oil. The high kinematic viscosity and HTHS of Motul 300V has more in common with Mobil 1 0W40 than Mobil 1 5W30.

i always use mobile 1 full synthetic. never trusted any other oil in my car honestly for whatever reason. always wanted to give royal purple a try but that purple scares the heck out of me

What turbo do you run? Ball or journal bearing?
If ball bearing, do you use an oil restrictor in the oil feed line?
Could be the problem.

That's what I meant by valve seals in the original post. They are good.

I followed the works instructions and properly primed it. Pulled the fuel pump fuse, turned over 4 times for about 5-7 seconds each. Something like that. Can't remember exactly. But I've driven it enough by now I would think all the manufacturing crap would have burned off by now.

That's whatI used when it was stock and never had issues.

You'd still be able to smell it right? I could smell it BAD before. Now no oil smell at all.

It's a journal. Garrett gt28. I think there is still a restrictor in the line.

lol, I'm sorry. I was totally trolling.

Just a question did you go all out when you installed the turbo or slowly broke in the car?
It could also be a pinched gasket.

For the oil part I highly dought it as I use to run 10w30 in my 06 wrx. I went to full syn Mobil 1 after my break in period. No problem ever.

I think you have an excellent point. I'm going to tell a little story that, at first, will read totally off topic but hang with me.

A while back, I replaced my original transmission with a salvage one. The first test drive seemed fine but it was only for a couple minutes. The next day on my way to work it leaked and sprayed oil all over the underside of the car. Looked like a disaster but ended up being only about a cup.

I had bought a rear seal ahead of time for the used trans but, after noting the good condition of the one it already had, I opted to skip it. As I gently drove my car home in the right lane, I thought to myself "Big mistake, you moron." Hard to believe though, because I've done this kind of work my whole damn life.

It turned out to be a tiny fleck of sawdust I had originally missed when I first inspected the oil seal. I flicked it out with the end of a zip tie and put everything back together. It has been perfect ever since.

Moral of the story is that I learned how little it takes to destroy the integrity of a shaft seal. Maybe it was the same for the turbo. @drz400dude, maybe you were unlucky enough to get the one in 500 with some shit stuck in a seal but this time it worked itself loose.

And I feel a little bad because of my joke but you gotta admit that was a pretty good troll. *high five* *bro hug*

Lol no worries. For as much as it cost it should be smokfree! But there is smokeLESS 2 stroke oil. So I figured hey, anything is possible.

Yea I'm not sure. But if I get any more problems works said they'd warranty the turbo no problem since I already proved it's not my engine.

No, the first time I started it up it was still on all 4 jack stands. I slowly let the temps come up. But it started smoking almost immediately. I thought what some others have said, it's just the new pipes, turbo, etc. So I took it for an easy drive for a few miles and it got way worse.

What gasket are you referring to? From what I understand (I've never taken a turbo apart) but the oil seals are a hard carbon substance, not like a rubber o-ring. I don't think you could pinch them.

Both works and the tuner have said it's kinda hit or miss with mobile 1 and subi's. Sometimes it works, simetimes it doesn't.
