As many of you know, Kerry Tandy's 502 powered Ken Rose coach ingested
something two years ago and he swapped in a new one. I finally got
around to doing a post-mortem on the motor. He left it for me at the
Dyno Shop in San Diego where the swap was accomplished. Kerry uses
Swepco Oil exclusively and is a dealer. He is religious about oil
changes and I have to say, that this is most likely the best looking
180,000 mile engine I have ever taken apart The crank mikes out
perfect and will require a polish only. The cyl bores are still
within spec and the rod bearings have the most even wear on them I've
ever seen. #1 piston got the hell beat out of it when someone dropped
something down the intake, (left impressions on the piston that
indicate it was round like a 1/4"ball bearing and that would account
for the broken compression ring. The inside of
I guess it goes to show that these things need to be driven and
nothing beats a comprehensive maintenance schedule.
