Hello!
I recently did a compression test on my buick 300. I got a decent 120# on all cylinders except the number 1 cylinder which read only 60# and it did not drop after sitting for 30 minutes.
Spark plug doesn't show any signs of mechanical damage nor any gas or oil on it.
I took the valve cover off and marked the pushrods and turned the engine over a few times and noticed one of the two pushrods wasn't spinning like it should.
Im thinking about pulling the pushrod to see if it is bent, and if it is, just replacing that to see where that gets me.
If I remove the whole rocker shaft.
Are those 4 bolts through holes where coolant could come out of???
Any other info yall might have would be greatly appreciated.
