Hey guys ill try to explain this as easy as I can... I was driving home and just lost oil pressure. Like gauge dropped! Started to here a chatter and I thought the oil pump went out so I parked it. A week later I started it. Still no oil pressure and has a very small tick? It runs fine! I guess im confused because if the oil pump or oil shaft went out or broke the car wouldnt run and the motor would lock up! Please help me!!

Weird. My 5.0 sort of did the same thing in augest. I had just done the timeing cover so isummed that some stray gasket material fell into the pan. My aftermarket jegs gauge still reads 20psi and I assume the sending unit is broken. My cluster gauge is normal, and never leaves the normal zone but occasionally takes a dip when the motors hot and it idels for a while. My engine developed a Tick on the passenger side rear cylinder that's pretty loud. It almost sounds like a exhaust leak. I try not to worry about it. The 302 pushrod 5.0 is a workhorse and can take some high mileage and abuse, they also like to consume oil with its low friction rings. I just keep it fed and happy, and it runs fine and pulls hard. I'd hook a manual oil Pressure gauge up to the motor on to of where the oil filter is Theres a factory sending unit. Back it out, screw in a mechanical gauge (may require adapeter fittings I belive quarter inch) and see what readings you get. Good luck!

My does that also, check your oil pressure hose make sure it's not clogged, also make sure the bolts at both ends are screwed in tight. Are you leaking oil at all or is the gauge just dropping? Sometimes it's the simplest things that'll get you

The stock "oil pressure gauge" is not even an oil pressure gauge, it's a simple on or off switch, hence why it's always "normal" or completely zero. Get an aftermarket gauge if you want any sort of reading on your oil pressure. Never cheap out on measurement instrumentation or count on a stock gauge. Autometer or bust.


I don't always reply but when I do, it's helpful

Get an oil pump priming shaft and pull the distrubtor and try an turn the pump. If u can rotate it with ur fingers the shaft is broke or u need a new pump. If u need a drill to turn it that's good. It could be the sender, factory gauge. My sender went out and it scared me so I have all new gauges Click image for larger version

I figured if the shaft was broke It wouldnt start?? And no its not leaking any oil at all... but does have a small tick but its not very loud. The block has 130k miles and the heads are gt40p and idk how many miles they have!
