low pressure

[stagg65]

my 1.9 diesel is running at 20 psi when hot and 24 psi when cold.
I think i may have sticky lifters, going to give it an engine flush then new oil.
kill or cure wish me luck

good luck but that very low cold pressure says mains are shot or oil pump is worn out I think

Hello,

what revs are these readings at? It's possible too that you either have the wrong pickup pipe, or the oil pressure relief valve is stuck open a bit.
