Been working on 216 engine for my Patter 12 C60L original engine still needs work so I’m going with a `52 216 cu.in. but prior putting the engine in the truck where it is so convenient to work on decided to do some extensive debugging on test stand. I’ve added a test stand page (still building page) to my web site
http://www.canadianmilitarypattern.c...ineTesting.htm what I thought you might enjoy is some really dull video of the engine running I’m trying to identify one sound that seems to come from the bell housing. Engine has about 2 hours on it at this time point so I haven’t read adjusted the valves yet. The sound doesn’t sound like the normal valve clatter. Any thoughts on the noise or diagnostic test suggestions will be appreciated,
