2 years ago I bought a crate motor through summit racing it is a atk hp74 and it was running fine untill about 3 weeks ago when I was coming home from work and I lost oil pressure. I got it towed home and into the shop and checked the pressure with a mechanical gauge where I still had 0 pressure so I removed the oil pan to see what was happening. When the pan was removed I found the oil pump and one of the main bearing caps hanging loose from my motor which explains why I had no oil pressure. Looked at all the connecting rod and main cap bearings which were tapered so I replaced all of them and repolished the crank and put a new high volume oil pump in. The problem is that now that I have it running again it’s throwing a p1345 code which I assume because the timing is a little off. But the main problem is it’s showing hardly any oil pressure at all so I hooked up my mechanical gauge again. All I have is 12 psi at idle at 700 rpms and when it is Reving its 20 psi higher if you follow the 10 psi per 1000 rpm rule. I’m just wondering if anyone has had a similar problem or if it’s fine to run it with that pressure. Thx for reading everything ik it’s long.
