22R Intake manifold failure?
« on: Mar 24, 2018, 12:10:00 PM »
My question is in regards to the intake manifold gasket on a 1981 22R California edition engine. The engine has 165K miles on it and runs strong, no lag in power or hesitations of any kind. The coolant is always full and no leaks have been detected on either the block, timing cover or head gasket. The oil is clean and free of any coolant.  The cylinder compression was tested and they were all reading at 160psi, +/- 2psi. The other morning, I noticed a cloud of white smoke coming from the exhaust during the engine warm up and initial drive. My initial though was that the head gasket was going bad. Though with the above observations mentioned I was wondering how possible is it for the intake manifold gasket to fail resulting in coolant to enter the combustion chamber? I pulled the plugs and only cylinder, number two show signs of being clean, i.e. steam cleaning from the coolant. Is this possible or should I concede that my head gasket is blown? I'm sorry I can not post a picture of the plugs yet since I have just joined. I did already post this in the engine section, but since I'm new,  might as well give it a shot here.

I would say you have a hg failure,  BUT  did you run a compression test after this happened?
