Bad oil leak after turbo install
So I installed a turbo last week sometime and have noticed a pretty bad oil leak. Obviously the first things I checked were the oil feed and drain on the turbo and the fitting on my oil pan and the leak is not coming from there. It appears to be coming from behind my damper and somewhere on the back of the engine. It also will not happen at idle but only after I have driven the car. It has gotten pretty consistent and is a fair amount every time so I was wondering what gaskets it could be, if anybody has had an issue like this before, and what I should do about it?

pics or it never happen. check the lines from the engine to turbo where oil is under presure

Front of the engine is cam seals, valve cover gasket, and front main seal. Rear is CAS, valve cover gasket, and rear main seal. Oil leaks down, do not replace anything lower than visible leaks until the higher ones are taken care of and brake cleaned off.
Beyond maintenance, you can have your oil pan and oil pump leak. Did you remove the AC? Did you replace the bracket bolt? |
Blowby that causes any real measurable crankcase pressure can cause literally every seal to leak.

A built bottom end means boost if it's a miata, and that means more ring gap and more blowby. That's why you are seeing built engines with oversized cam cover vents, more flow/less resistance and so less pressure.
