Rod Bearing Help (Page 1/1) David Bartlett MAR 21, 08:47 PM Hi all, 86 V6Gt, Connector Rod Bearings to replace say GMM400 18007586., bottom says 114p632 Any info on these? Not sure if these are stock or standard. I ordered a set of standard size BB285jstd, but clearly different. No knock or spun bearings, but since I was in the pan, time to replace. Thanks for the help? olejoedad MAR 22, 08:07 AM How many miles on the engine, and what kind of oil pressure whet at operating temperature? 15 psi at idle and 10 psi per thousand rpm is just fine, no need to replace.
