1939 Packard Twelve valve noise

Posted by rhanna On 2016/8/9 6:55:26

Just purchased a 39 Formal Sedan. Engine runs but has 2 issues. One head has been welded in the past and is leaking. I plan to replace both heads with new manufactured heads from Empire. The valves seem to make more noise than I would expect. My plan of attack here is to remove the oil pan and then remove the oil pump clean the metering valve. If anyone has experience with the V12, I would certainly appreciate some insight here. Are there any O-rings or seals on the metering valve? Is there any adjustment on the valve silencers or tappets? Should I try the metering valve and see what happens or go ahead and remove the intake/exhaust and valve cover to inspect the Silencers? Car has 44,000 original miles in very good condition been in the same family since 1960 with good care. Also the shop manual is ok but would really like a better "how to" book on the engine. Is there anything available? Anything to watch out for during this work?
