1994 Chevy lumina mini van head gasket
I have a 1994 chevy lumina mini-van which I think has a bad head gasket. The head that is near the fire wall it is the 3.1 engine. The check engine light came on I got a 14 coolant sensor and 44 oxygen sensor. What had happened was the water pump went coming home on the thruway by the time I could slower her down and pull over I think the damage was done. I replaced the water pump drove her home what she does is idle rough real rough but there is no water in the oil or none in the exhaust. The pcv is going crazy it won't even stay in the grommet so I think the pressure is real high down below. Anyway the back head gasket looks like a joke to change. What I would like to know has anyone done one of these and found it to be hard or easy and any tricks. I would also like to know if anyone has any other ideas what it could be as it has plenty of power on the highway it's just idling it sounds like a 1969 Z28 with the 302 and two 4bbl. Any suggestion's would really help. Thank you!
