JR,

Haven't we discussed this before?

Just curious why ( can't remember) you are a opponent of running Marvel
all the time.

It most certainly will keep the crud inside the engine, from starting in
the first place.

Pontiacs (372's, 389's, 421's,428's 455's) had this problem at start up
for years, and the engines ran like a raped apes. ( Old's and Caddy's
had the same start up clack)

And in my youth, always ran Marvel in my "Tin Indian's" and never had
the start up clack.

A collapsed lifter, will cause zero catistrophic damage to any valve
train, unless the rocker is so totally out of adjustment, the push rod
jumps out of the lifter.

Then you have problems.

Hey, How bout Jeff Gordan and Chevy, winning the Brickyard 400?
