TO-30 Z129 engine.
Attempting to identify the cause of low oil pressure, I pulled the bearing caps to check clearance and also opened up the oil pump. Clearances were well within range, pump gears were quite sloppy. A pump rebuild is on the list now. I put it back together to use until I get the rebuilt kit ordered.
My problem. I now have a leak around the rear main seal that I did not have before. In reading the archives and also re-reading my manual (I-T shop manual) I suspect that I messed up the seal itself or more likely the packing along the rear bearing cap.
Confession. I never fully removed that cap. It was loose but didn't want to drop; I couldn't figure out what else was holding it in place. By then I know the pump was sloppy and that all other bearings were near perfect. Figuring I'd let it as is to avoid causing problems, I just retorqued it and quit. So what did I do?
Does someone have pictures or at least a better description of how this all goes together? Not knowing what I did I'm not sure how to correct it. It's certainly useable, but it didn't leak a drop before.
