Path1, that is some excellent information, thanks very much for writing that up. I did a bunch of research on the 5.9 cummins before I purchased the RV. I knew what I was getting myself into. No, it's not a 330 CAT, but it's been a great engine so far.
I do have a 53 block, and I have checked for cracks where they would normally appear. No cracks anywhere visible, and it does not use any coolant or run hot.
The VP44 injection pump replacement scares the hell out of me. Not because of the work to put it in, but because of the cost if it does decide to fail.
I did some google'ing lastnight and found that the stock lift pump is a weak link. Sounds like they used to be mechanical cam driven until '98 or so. Then, they switched to electric. Not sure which one I have yet, haven't even popped the hood to see.
I was looking into either a FASS or Airdog filter/pump setup. I know from reading about them and talking to people who have them(family members) that they are bullet proof. Looks like the 100-150 GPH style frame rail mounted pumps are between $500-700, depending on where you buy from. The Raptor FRRP (direct replacement) is about $300.
I don't just want to start replacing parts, I want to make sure a part is either on it's way out or completely failed before I throw money at it. I have researched the killer dowel pin as well. I don't know when they stopped having that problem from the factory.
