Hey, I turboed my other car (85 nissan 200sx), and there's oil everywhere

I ran it for maybe 20 minutes with no blow off valve, only boosting a little (like 2-3psi). I was blowing off intake pipes. I noticed at that time (since the intercooler pipe was off), a couple teaspoons of oil in the intake pipes before the intercooler.

At that point, I tightened all the clamps and installed the blow off valve.

I drove the car not more than 1/2 a mile when smoke started pouring out. There is oil on the outside of the turbine/hot side of the turbo.

I tried shortening my oil drain line and making sure it didn't have any traps (aparently that is bad).

I took it for another drive with the same results, lots of oil in the exhaust, and more on the outside of the turbine side.

Did running without the BOV cause this? Is the turbo bad, or what do I look for in my setup that would make it leak oil this bad?

 

Oil on the outside of your turbine?

Sounds like an oil supply leak.

 

bad turbo?

 

I checked that first, there's no oil near the oil line fittings or lines themselves.

It's coming out of where the manifold mates to the turbo, and out of the exhaust.

Some nissan heads indicated a fault in my valve cover plumbing, hopefully that's all it is.

 

How can anything come out there? It's supposed to be a sealed interface.

This Nissan seems like a POS.

 

Hmm is this a new or used turbo? Check your shaft end play. I think the internal seals in the turbo might be bad happens to older/high mileage turbos but not uncommon on low mileage hard ran turbos ; ). Simple rebuild on turbo could fix it.

 

how much oil psi is the turbo seeing? what size oil line do you have for supply, what size for return, how restricted is the return, return above/below oil level in oil pan. ---- and same issue with new turbo but fixed it rather easy.......

 

Rebuilt turbo... turns out it's a bad idea to let boost get in to the valve cover. Oops.
