Bottom of lifter worn thru
You gonna send me the money so I can afford to do that?
Lessee here....(Breaks out adding machine)
YOUR time, YOUR replacement gaskets, YOUR metal-filled motor (cam, lifters, oil pumps, bearings, etc. etc.) YOU paying someone else for machine work, YOUR coolant, YOUR oil, YOUR oil filter, possibly a tow...
Yeah, you're right, it's way cheaper to run a flat tappet-cam, especially with the oil additives and break-in springs and blah blah blah. ;-)
