1937 Posted December 29, 2006 Posted December 29, 2006 Hi everybody from Bill Glenn in WV. I have 2 pre-war beauties, a restored 1937 Century and my latest project, an almost restored 1940 Century.I am cleaning up my 40's engine and checked the compression. It registered 110 in 7 cylinders and 105 in one. Are those good numbers or should it be higher? Or have I forgotten something that every Buick man should know?
Matt Harwood Posted December 29, 2006 Posted December 29, 2006 The actual numbers are less important than all of them being about the same, and 110 seems to be about right for these lower compression motors. Since the numbers are all in the same neighborhood, there isn't any indication that there is one failing and it's likely that your '40 has good compression and is probably within spec.Hope this helps.
1937 Posted December 29, 2006 Author Posted December 29, 2006 Thanks for your response. I thought it was OK but I am more of a body man than a mechanic, so I wasn't sure.Bill GlennBCA#42476
