Rear main seal??

OK, my truck started leaking oil.. it is a 2000 f-250 with a 7.3.. I have a chip in it also..on lowest setting..

I am getting a huge puddle of oil when the truck sits.. I crawled under to take a look and all around my starter and the transmision is covered with oil.. No part of the motor has oil on it..

the oil filter is not loose and is clean...the oil cooler line seems tight...

Drips of oil is comming out of the dust cover where the flywheel is located..

anyone have this problem? Does this sound like a rear main seal? any help would be apreciated.. Thanks JIM..

Use a flash light ang look on top of the engine under the turbo. I'll bet you have oil in the valley back there. It is probably a HPOP line leaking or turbo pedestal seal. Almost never the rear main.

I believe that I am having the same issue on my 99; however, there's quite some build up under the engine...have to wash it up and look again. About how long is the repair, a few hours or a few minutes? I'm not a mechanic by any means, but have worked with the 6.5L HMMWV motor before.

Are there any links for the replacement of the HPOP Seal? I am very mechanical, but don't want to tear down any more than needed. I may remove everything from the top of the engive and degrease it all. Thanks for any assistance.

it doesnt take that long , i can do em in about 20 minutes , but i do it everyday , u still should be able to do them in an hour very few things need to come loose to do it, all i ever take loose is the lines going into the pump and then remove the fittings , replace o-ring , reinstall fittings snap lines back in

I remember seeing instructions somewhere on this site for replacing the o-rings on the HPOP. Does anyone know where the link is or where I could find links to these repairs? This is a pretty common problem for PSDs', the parts should be available at the dealer, correct?

Any special tools required to disconnect the oil lines. I have the same issue on my 2003, leaking bad all of a sudden, puddles under the turbo and I see the trail leading from the oil lines at the connections to the HPOP. My manual says you need special tools to disconnect the lines. Are these readily available o-rings or are they dealer only? I to wrench on my truck all the time but this will be a first for me, would love to see a link to this repair.
