What causes crank case pressure?
Powerful spikes in crankcase pressure are a classic sign of a blown head gasket, or a cracked engine block. Leaking exhaust valve seals will also contribute to spikes in crankcase pressure, which are particularly noticeable because the valves are just below the oil filler cap.
What does it mean if smoke is coming out of my oil cap?
The Culprit: Exhaust Leakage Like smoke coming out of your tailpipe, you can attribute smoke coming out of the oil cap to exhaust. The valve stem seals and piston rings degrade over time. If you see smoke coming out of the oil filler cap, it means that the intake valve stem seals or piston rings are bad.
What causes white smoke from crank case breather?
Re: White smoke and oil emissions form crank case breather on diesel engine. 02/23/2015 4:15 AM. If oil is coming out of the breather and there is a shortage of oil in the crankcase, then these things are most probably related. The cause is insufficient maintenance activity.
