Since I purchased my car it has had a rough idle and lack of power... just one of many issues that needed addressing. I found the carburetor base and spacer plate gaskets leaking so replaced them. Still ran rough so tossed new points and condenser at her... no change. Performed a compression check, sure enough #4 cylinder zero compression. Oiled cylinder, no change. Yesterday I pulled the head on the right bank. Sure enough a burnt exhaust valve. What I was not expecting was every push rod was also slightly bent.... found same with the push rods on the left bank. I am guessing this motor hand sat for a very long time as you could see ring marks where they had stuck to the cylinders! Oddly there was not a tick to be heard from the motor. The cylinder walls were smooth, she does not burn a drop of oil, all other cylinders the compression was 175 to 180 psi. Lifters all were ok and so was the cam... only 47,000 miles on the car. So heads are at the machine shop for new hardened seats. Hope to have her running correctly by next week!
