i bought a motor off a member here that was supposed to be fresh ready to go... put it in the car and had heavy blowby.did a leakdown just on one bank and 3cylinders where over 50%!!!!had to pull the motor rering it and fix the heads.i spoke with the owner and asked to just cover the cost of the heads to get repaired which was $300(cost me $1200 for everything)he said sure chq is in the mail and never got a thing......supposed to be a reputable guy in the mopar community turned out to be BS.i wouldnt trust MM after reading these posts but im sure there are alot of places that somebody out there has sour feelings for they just never mention it.
