So first off, why is there not a specific motor section in the forums? Hopefully I'm putting this in the right section, but I can't find a motor/ motor builds/ motor issues thread.

Well I posted a thread a while back on an issue that I thought was caused by my oil pump nut backing off. I pulled the motor to change the pump and found the nut was rather tight and took a 2ft. breaker bar plus a little umph to get it off. After dropping my oil pan I found some large chunks of metal, that look like a bearing went. So I'm now wondering if a crank bearing went and the debris plugged up the oil pick-up tube causing my non-existent/low oil pressures. I never heard any odd noises til my gauge stoped to 0psi oil pressure, and I'd think I would have heard noise of the bearing going bad. Does this make sense

Now comes the tough part of deciding how to fix the problem. To have a new bearing installed and the crank balanced is going to cost a bit. Plus while the motor is apart I don't know if it's worth trying to do lbz rods and cut pistons or not. I don't have a lot of money to throw at this truck and I don't need a built motor. I'm looking for a reliable 5-600 horse that will be a daily driver. Should I fork out the money for motor work, or try to find a good bottom end (lly or lbz)? Also would you upgrade while it's apart or would it be a waste of money?

Haven't got that far yet. I wasn't sure if it's worth tearing into if I'm just going to buy a used bottom end.

Motor is already out. I knew it would have to to do th pump. I just don't know what my better route is. I guess I'll start looking for a solid bottom end to swap my parts on to.

Thats what i would do and you will wind up with fresh head gaskets and throw in a set of ARPs and you will be good to go.

Already did arp studs and head gaskets to this motor less than 5k ago, along with all my other mods. Had George "big dipper" do my trans less than 500 miles before this happened. Kinda sucks that now I've gotta shell out another 2-3k.

Does anybody know if any damage would have been done to my top end with that metal iny oil? I'd like to use my top end if I can.
