Default Oil leak but dont know where! ej20g

have an ej20g swap and i seem to be burning oil somewhere, cause i can smell it when my car sits after running and at red lights. There is no smoke coming out the exhaust or in the engine bay. I am down about 1/2-3/4 quart for every 30-50 miles. I had the timing belt and oil pump seals done about 10K ago, but not totaly ruleing that out. When I had that problem before you could see and hear oil hit the exhaust manifold and thats not happening this time. Motor has about 75k on it and I just got a tune and turned up the boost for 12.5psi to 16.5.

I am going to see if it might be the rear main seal today but anyone have any other suggestion?

put a peice of carboard under it overnight, in the morning you will see where the splatter marks, if any are, and be able to tell where to look.
Good luck.

Is the turbo whining??? My turbo started whining last summer and then my oil consumption went up. I had no apparent shaft play but there was oil in the intake tract. I'd say turn the boost down a bit until you figure it out.

That's a LOT of oil to be using every 30-50 miles.

GL sorting it out.

With that kind of consumption, it sounds like bad crank bearings, but no tailpipe smokes makes that seem unlikely. However, when I had bad bearings a few months ago, I didn't have very much tail pipe smoke once the car warmed up. But my oil consumption was about the same. When I got the block out and torn down, I had 3 spun bearings and most of the crank and rod bearings were scorched.

I doubt it is the rear main if you aren't seeing oil drip between the tranny and the engine. If it is leaking that bad, you will be pooling. Personally, from what you have said, I think you are burning it off internally. Do you have an oil pressure gauge? That is a key instrument on a turbo car...
