[DeTomaso] 302 diagnosis

[JDeRyke at aol.com]

Dennis, run a leak-down test. This is NOT the same as a compression test and 
will give much more info about engine condition when run by a competent 
diagnostician. Yes, it sounds like a valve-seaing problem- or a timing chain. 
Smallblocks have the same timing chain issues that Clevelands do, including the 
sheared or partially sheared drive-gear roll pin. But due to the shorter chain and 
smaller lighter valves, it takes longer for the chain to wear out. How many 
miles on this engine? Good luck- J DeRyke
