got a ford f150 use to haul our mini stock with, when it's sitting idling (after 2 to 3 minutes) oil presure starts dropping. has a gage but without numbers. If not careful light will be on in about 3 minutes. any ideas on what the problem might be would be appreciated oh it has a 4.2 v6 with about 80,000 miles on the engine.any help is appreciated thanks

Pull oil pan and clean out sludge and replace pump while inside. You can do this without removing motor if you pull fan and shroud. unbolt mounts and cherry pick engine up till it rest on firewall. Its dirty and tedious but can be done. I would pull it enuf to replace mains if it were mine and worth the truoble

A cheap oil can caua=se this problem.
When my car had only 12,000 miles on it oil pressure was to low after an oil change, then put penzoil in with the same 10w30 and the pressure was up by 20lbs.

(the oil that caused the problem was havoline)

A guy that I work with had one that would drop pressure going down the road, would drop to nothing. He wound up changing the oil and filter and no more prob. Come to find out there was some sort of problem with the filter and it would start by-passing causing it to lose pressure.

make sure there is no water in the oil they are known to have some timing cover leaks contaminating the oil depending on the year it is.The oil pump is on the front cover and has 2 gallies going in to the block.if you do the timing cover plug them 2 holes so you don't get old gasket in them.Old gasket in them holes = fryed bearings later.You might check oil pressure with a mechanical guage to make sure its not an electrical problem.Also check plugged screen,plugged drain holes in the heads,and how often do you change it and what kind of oil do you use?????????????
