Just wondering what weight of oil you guys and gals are using on your cars.
I have oil leak that I just cannot get to stop. Its leaking around oil pump and oil pan on timing belt side. replaced all oil pump seals and the pump was brand new when i installed it and leaks around oil pan. I have replaced that gasket 3 times already. Im using 5w 30 mobil 1. Any help would be appreciated.

Thanks

 

Alos any ideas on how to remove some pressure from the crank case. I think thats a mjor factor in my oil leak.

Thanks

 

hahahaha i'm having the exact same problem on my boosted h23. can't pinpoint where the leak is coming from, but i also put a new oil pump on 2 months ago but i'm pretty sure its not leaking from there.
there is oil all around the oil pan gasket tho, despite being a BRAND NEW gasket and using black silicon. i didn't wanna tighten the bolts too much or too little, cuz my torque wrench doesn't go down to 7ft-lbs

i have a FEELING its coming from my turbo cuz i just found some decently loose bolts on the bottom of the turbo and there is oil sprayed ALLL over the front of my block, directly under the manifold.

 

as for the crankcase pressure, the hose that runs from the VC to the intake/IC piping, mine is open right now cuz the piping doesn't have a nipple on it, idk if thats a good or bad thing or what
