Re: Oil pressure is really low
30 is normal when cold and running over 1500 RPM. 15 is not bad at idle. This assumes your gauge is accurate. Constant low means worn oil pump OR old main and rod bearings. Have you ever ran the compression on the engine? That is where I would start as a general indication of the age/condition. Also, since it has set for awhile I would get a few miles on it before tearing into any thing so things can tighten up. My 64 Chevelle had sat for years with occasional use. When I started driving it daily, especially at higher RPM, it smoked and leaked like crazy. After about two weeks the seals, rings and valves tightened up and it went strong for another 60K. What weight oil are us using?
