1997 7.3 oil leak

my truck is leaking oil bad! i know for a fact the rear main is leaking. but it is also leaking from the front too and its not the crank seal. i already checked the HPOP reservoir and not that either. can anyone tell me some more places it can leak from?

Mine was leaking from one of the "Blank" plugs on the HP oil galley. I replaced it and put an HPX line in, but you could just tighten/ replace O-ring (I think they're O-ringed)

just another place to look... good luck

Also check the big bolts o-ringed at the end (front and back) of the galleys or the valve cover gasket

Check your turbo pedistal and under the HPOP. The plugs on the HPOP have been known to leak, I've been there and done that. Good luck.

Robb, they are O ringed but it doesn't sound like 1a2a3a's problem.

Ah, I guess the oil would run into the valley and to the back of the engine... he said the issue was the front. Thanks for catching that

Oh, no no. Just step back and take a break. Get the PSD running and you'll be a lot happier with it then a 351. Of course, I should just mind my own business!! LOL

mine looks like its leaking on the passenger side somewhere. the driver side of the motor is pretty much dry buy the passenger side is soaked. and yes i do have a crap load of oil dripping off the crossmember but the oil cooler is dry. do you know of anything on the passenger side? the valley on top is completely dry and same with HPOP lines and plugs.

It might be coming out of where the oil dipstick goes thru the oil pan. That's always a common leak area.
