Hello all,

I posted this in one of my old Threads, but thought I'd start a new one with the correct title. Can someone please assist me with this.


I finally got a compression tool and checked compression on the cylinders. Hopefully I did it right. I hooked it up and turn engine over and the readings I got are below.

1st Cylinder: 60psi
2nd Cylinder: maybe around 20
3rd Cylinder: maybe around 20
4th Cylinder: maybe less than 20

After letting the key go, they pressure immediately went to zero.

What does this mean?
