You’re absolutely right, if replacing the relief valve doesn’t give me consistent, good pressure, then that’s what I’m planning to do. I already have a fresh cover sitting around somewhere, just wanted to give the reasonable and easier solution a go before the bigger job.That pump is Sooooo awful. replace the front cover with an early ‘97 disco (IIRC) that had both distributor and crank driven oil pump And convert to SERP belt. Yeah, you have to change ancillaries too, so what. 100% Worth it imho to have better oil pressure. I hate distributor oil pumps— I went through all this before Too.
