That's probably exactly what happened Neal. How long had this car been sitting? Had a similar problem with a slant 6 that had been sitting for a few years and I didn't even use the Marvel Mystery oil. Fresh detergent oil was enough to loosen up the sludge and I spun number 1 bearing.
Btw I always used to use Fram filters but after reading an oil filter test and report I'll never use them again. Turns out they're one of the worst filters on the market. I was having a problem with the 440 in my 63 Fury. Sometimes when I'd start it the oil pressure was slow coming up and the lifters would clack. Since I changed over to NAPA Gold oil filters (made by Wix) I've never had the problem again.

Last year my friend changed the oil on his Buick Grand National. He used a Fram filter. Long story short, that filter didn't let any oil past it. It was somehow defective, and I've never seen an oil filter do that before. In your friend's case, this would never have allowed him to go 100 miles without him hearing knocking, but perhaps the filter is to blame? I'm only guessing, but I'd put a new, quality oil filter on it and start it briefly, making sure the filter has time to fill. I'd then remove the new filter and take a look. neal zimmerman wrote:any chance marvel mystery oil in a crankcase could make a motor blow up??? A guy here i know bought an old Ford with a 289, it ran good enough. Upon getting it home he changed oil and filter, adding a pint of Marvel mystery oil into crankcase and the other half of botttle into gas tank. The motor made it about 100 miles and then blew( sounds like a rod-knock to me). In that 100 miles though it ran like a top and sounded awesome, no noises of any sort, made good power too. I took off the oil filter and it was not only cold, it only had a little oil in it. This sounds like a plugged sump pickup to me and made me wonder if the Marvel had "Cleaned" the engine too well, loosening up tons of sludge and plugging the pickup?
