Heard a slight pop then had smoke coming out of my turbo. There was oil burning in my turbine side. Only happens at higher boost levels, 12 PSI or higher. I bought a rebuild kit. Didn’t help. Any ideas? Had the turbo for like 2 years 7k miles.

 

do you have a catch can? can you post up the routing of it?

 

simple system with a check valve. Going to run a dual open setup. Waiting for my valve covers to come back.

 

Well. If that's a sealed catch can, under boost the check valve closes and the line off the valve cover is going to a sealed can with no vacuum. You might as well remove the line off the valve cover and plug it is that's the case.

On the flip side, if the catch can has a breather cap on it, there's zero reason to have a line from the manifold to the can, because it will just be pulling air from the breather cap and not from the valve cover.

Either way it's wrong, and the only situation I see it being right is if the can is sealed and the manifold never sees positive pressure and the check valve never closes, which isn't the case here.

 

got the catch can from trick turbo. It’s one of their kits.

 

I used to have issues with my Elite Engineering sealed can above 12psi on my Trick Turbo setup. After a pull, I would smell burning oil and the dipstick would be pushed out a little. Best thing to do is run a Mighty Mouse PCV type can and drill out the driver's side valve cover orifice for better venting.

 

Thanks for the input guys, I appreciate it. Will turn down the boost until I can do some more research and save some dollars.
