So... I bought a 2000 Jeep Cherokee 4.0 and the next day I found it had a crack cylinder head.
I had the cylinder head replaced and I am worry about the oil pressure reading
Cold start it's 40+ psi
Warm idle after 30 minutes just at 10 psi
Cruising at 45-60 at 1500-2000 rpms around 20psi.
PSI does increase with acceleration but nevers seems to go above 30-35 psi.
I had the mechanic check it with a mechanical gauge today and he read 14psi at warm idle and 35-40psi at cold start. He is telling me it's lower then he would like but to add 40 weight oil and keep an eye on it.
Thougths on my readings? Acceptable? dangerously low??
Keep or sell it? I bought it for $3600 and already spent $2000 it 3 weeks on this Jeep.
If Keep? Add 40 weight? Drop oil pan at some time to replace oil pump?
