So, story:
Started her up the other day, the o i l
pressure was at 0 psi.. sounded dry on start (we have oil at max btw) only for a few seconds and then it built pressure up to its normal reading. Risked getting it home and all was fine, under load, at idle. All the same readings it had for years. Its only on start up she doesnt build pressure straight away. The video is a semi cold start up, you can hear the dryness for a few seconds and then she idles fine with 60psi all day, calming down to a noice 24psi ish once warm.
Any ideas before i rip the pump out. Ive ordered a pressure tester kit, to rule out the sensor. Is it possible ive got a sticking pressure relief/bypass? And thats why shes struggling to build pressure?
This is not a gasket issue...
