Seafoam?

[87-250]

Apparently my 351 has a failing lifter and some blowbye. I know what I should do but would Seafoam, Marvel Mystery Oil, or Restore do any real good? Money is tight so replacing lifters, etc. is too much $$$$ right now.

Seafoam is great stuff but it wont do any thing for this problem, its more for sludge/carbon build up removal..

blowby is probably rings, and the lifter is probably oil pressure, use some stp with 20w 50 for now, a rebuild is in your future, and there is no magic fix

Yeah, that's what I'm thinking. The STP 20w-50 is a good tip. I'll do a leak-down test in awhile which will tell me more.
