Instant oil leak 91 4.0l

[AKMark]

I was stopped at a light and watched my oil gauge move from right on mid range to nothing. I put the truck in neutral and reved and the oil pressure came back up for a moment.

Drove the two miles home and found that I was leaving an oil trail all over the road.

From underneath the whole bottom of the motor is covered. Started the truck and it looks like the oil is just streaming out of the oil pressure sending unit.

Please pardon my ignorance, but what should I look for besides the sending unit?

Thanks.

Unfortunately, they sometimes fail that way !

P.S. Reving your engine with zero oil prrssure is a good way to make it go BOOM !

I would suggest looking to see where it might be coming from (hose it down and wipe it clean)....might be your front or rear seal.....also check the valve covers as this is very vulnerable if you don't have the good fel pro steel gaskets....obviously the oil temp unit might be bad and that is where you are getting sporatic readings on your gauge
