Q: Oil is geting into intake manifold and into all intake vavles.
All my spark plugs are soaked with oil. believe i have a bad valve seal or blown head gasket cause #1 cylinder has 20lbs compression,#5 has 120lbs. So i was pulling my intake manifold when i found oil coming out of the intake and straight onto the intake valves. I could hear it sloshing around inside and i poored about half a quart of oil out of the intake manifold. My vehicle has 162,000 miles. I have no idea how this much oil could get into the intake manifold and then into the intake valves. Pls help
