I'm sure it is a thing but your average garage mechanic isn't going to do it they will order a new one and R&R it heck even today they may just do a straight engine swap because a reman engine has a warranty like said cost effective.
Well, I can get a new roller for my magnum for almost 400, or I can get one from the bone yard, send it out for a weld regrind for quite a bit less.... cost effective...
My point is, all of this crap on this thread is based on someone (not saying who, they know who they are) are jealous as f*** he's getting attention and the petty jealous types aren't... They would rather scream from the rooftops how much of an idiot UT is.
It's way easier to knock someone else down than to elevate ones self, and that is almost always how these threads begin.....
Reminds me of the kid from the Simpsons with the annoying laugh..
