<VV> Diagnose engine "knock" ? pushrod tubes

[Charles Lee]

JR,

Correct - the pushrod tubes are stuck tight, and I don't want to crush them,
so I "liquid wrenched" them yesterday to loosen them.

There were no rockers that exhibited any abnormal behavior (that I could
see) and none were loose, so we see today, I hope ...

Thanks again
Charlie
