Oil leaks 850

I am leaking oil from everywhere, including coming out of the dipstick. I think I have a problem with the crankcase ventilation to have this many leaks, I would appreciate any help someone can give. Thanks!

Oil leaks 850


Hey Rand, first if there is a oiling problem "leaks" things wear out. If the car is leaking as you state every where. Even the dip stick, that is proof of a crankcase vent problem, I'm not aware of any valve that vents the pressure to the atmosphere or regulates it back to the cumbution chamber. It goes directly back to the intake to burn the crankcase fumes. The pressure gets built up from combustion pressure getting past the piston rings, thats the only way the pressure gets so high, that it vents itself, as in your case the dipstick, maybe the front crank seal and the rear main. Those are the only places that it will finds its own vent. In other words where ever there is engine oil pressure it shouldn't leak.example- Oil pressure, turbo seal as well. In racing when the crank case pressure sky rockets the engine is not far from giving up the ghost. Remember they build the most power right before they blow so have fun! Just kidding, Drift

Is there a flame trap for turbo 850?

No flame traps in turbos 850

No flame traps and the car runs good, so no piston problems either.
