#1 Cylinder seems dead.
Hi. Been a long time since I've been on. Having a bit of a problem with my 340. #1 Cylinder is staying cold. I used the water on the header trick. Definitely cold. I then checked valve adjustment. It is a Crane solid roller cam 509". The rockers were a little loose by a few thousandths, but not so much that any damage should've happened. They are pro comp heads and rockers. After readjustment on the rockers, I then proceeded to do a compression check. Here's where I am lost. #1 is showing 170 but not doing anything. #2 is only showing close to 160. 158 after sitting a minute or two. However #2 fires just fine. My fuel pressure from the Jegs Holley knock electric pump off keeps climbing no matter how much I adjust the regulator out. I have tried three different regulators to no avail. I cleaned the #1 spark plug and fired it out of the cylinder. Great spark. So I have cylinder pressure and spark but a cold cylinder. Car runs like crap.
