I have a 1996 Dodge Grand caravan that has a 3.3 liter v6. It spun a rod bearing. After inspection a discussing with area mechanics, they said I could put a standard bearing in place of the spun one as long as I didnt see any brass on the bearings. So I replace the bad one (#6) and tested it out, it only made a knocing noise for 5 seconds then ran very quietly, compared to LOUD KNOCKING. I took a test drive at 34 mph just to bread it in. Only momentarily went to 60 and it sounded like valves clattering, but not rod bearing sounds. Anyway, I pulled the oil pan to go ahead and change the other 5 bearings and the #6 had spun again. NOW I hear that the cam shaft gets egg shaped when a rod bearing is spun and its best to replace it or put a used motor. My price range only inclueds changing the motor with a used one. Is there a file that I can download with step by step instruction on removal and installation of the engine, and how much would it cost

dang, I am not sure if my comment got back to ya. SO I am reposting. I did mic the crank. My first measurements were, on the good shaft .0680 and on the bad, .0675 inches. Then this guy that mentioned EGG SHAPED crank after spun rod bearing, I remeasured and took 3 measurements as I turned the crank, those measurements were .06735, .06745, and .06755. Is there ANY OVERSIZED BEARING that can overcome this egg shape and perform normally. I mean like, paying $15-$25 for a special bearing beats the heck outta having to swap out the entire motor, even if the motor was FREE. and GOD knows, they aren't free. P.S. I am a member at autozone and have browsed for the engine replacement guide, perhaps I will have to call the store and have them guide me to that section. Any. . .what about the oversized bearing working on egg shape?? Thanks, Mark dang, I am not sure if my comment got back to ya. SO I am reposting. I did mic the crank.

Crankshafts can be "reground" and then the oversize bearings will perform fine. I have purchased "crank kits" that include a ground crankshaft and bearings. If the journal is not round, then NO bearing will perform properly. Crankshafts can be "reground" and then the oversize bearings will perform fine.
