Okay pick up a 1991 3.1 v6 had a bad vaccum leak. Looks like some one replaced the heads. painted blue and a new plug cap on one of the back heads.

Pulled compression test on engine was good betweeen 130-150 PSI before doing intake gasket and timing chain.

Just put it back together.

Now here is the problem. No Compression in number 4 cylinder. Have tried adjusting the valves a number of times and still no compression.

Have done both ways that I read about on the boards to no avail and have use my 1992 factory sevice manual.

The push rods do move the valves just dont know if they are opening the valves. Since no compression. Is there something I am missing. If the intake gasket was cocked or moved during insulation. Would that casue a no comression issue.

I dont think so but I have to ask. Have done intake on 3.1 before and have never had this problem.

 

Got iot figured out
