"I decided I would perform a compression test before sinking any money into manifolds and risers on my pair of 440s. All going OK until I got a 30psi reading on one of the cylinders. I ran the motor up to temp and up to 2500rpm to break any crud free if it was just a sticky valve. I also put oil into cylinder to see if that would temporarily seal a bad ring. Only got up to 45psi with oil, then back to 30psi after running motor. Lots of blow by from rocker cover also. Engine runs OK but a bit smokey from exhaust and rocker cover. Any words of encouragement would be appreciated.
