[QUOTE="stutaeng, post: 26512, member: 6175"] Confirmed. No fractured connecting rods caps on my 99 4.3. Some photos. All my bearings were shot. Looks like on the cam bearing, the upper portion of the bearing wasn't even touching the camshaft journal... Engine had about 5 psi at hot idle...and everyone kept telling me, "change the oil pump, that's your problem!" I knew better. Actually, the ONLY thing that I could have used WAS the oil pump, LOL. I didn't check the cam bearing clearances because my dial bore guage didn't go that small, but the rod bearings were close to 5 thousands on the clearances.
