When it runs out of all fluids...... Mine is a bunch better but I don't think I will ever be able to park it on a white showroom floor and not make a mess lol.

 

I was told years ago that a 7.3 leaked, and when it stopped leaking it just meant it was out of fluids! I guess that's the price you pay for having a 20 year old truck that still runs like a scalded dog!

 

That's why I'm glad my new house has a small paved driveway to the garage door and the rest is dirt and rocks. This way I don't make stains where I park

I don't mind the seeping or a few drops every now and then but I gather a few puddles (not counting the A/C condenser drain) if I park anywhere more than 10 minutes.

I got the fitting repaired and fired it up to test it out...tight seal and no leaks. Success but not victory. While the truck was idling oil drops were coming off the rear still. It's better than the steady stream so I'd say I fixed 85% of the issue. I won the battle but am still fighting the war.

I poked around with a flashlight and could not see any obvious signs of another leak on top. Granted it's pretty crowded up there with everything installed so I can only rule out a few things like the rail plugs and my HPOP fittings. I don't have an EBPV any more so that's not it. I lost my small inspection mirror during my injector job so my larger one only fits in so many places.

The valley still has a decent amount of oil in there from the spewing outlet fitting and hopefully it's just some residual oil that was pooled up finally draining when the engine is vibrating (doubtful but I can dream).

I topped everything off and drove to work today and made it. At least I can keep up with the makeup rate so my wife can have her Jeep back. I will go out and check the puddles under the truck in a bit to see what systems are still ailing.

If nothing presents itself I'll clean up the valley this weekend and camp out up there to see if oil comes out. I'm due for an oil change soon and I might add some dye this time to see if I can follow the trail. I think Sous did that awhile back and I'll have to dig up that thread. The other two possibilities are the passenger's side rear oil plug and, dare I say, my rear main seal.

 

Have you replaced the o-ring on all 6 of the plugs in the heads where the 8 holes are? 2 are where the hpop hoses go into the heads. One of those was my big leak. Under the glow plug relay where I could not see it. The o-ring is harder than a normal one. IIRC 90 instead of 70. I only did where it was wet but need to go back and change the others. I got a package of 25 o-rings for it.

 

I don't think it ever leaked unless the hpop pressure was high. Never saw it at idle.

 

When I went to the T500 I replaced all the fittings (HPOP and heads) and got the new "updated" OEM lines. The passenger's side head fitting was a leaker back then. The drops are happening at idle so I should be able to see the leak without building any pressure.

I'm pretty sure it's oil and so far I've ruled out the fuel bowl (although I can't quite see under the fuel pressure fitting for my sensor), all 4 HPO fittings, HPO head plugs, EBPV (), and most of the HPOP-to-reservoir gasket. I can't see under the HPOP so I can only rule out the backplate and the fitting above the IPR (can't remember if that's the serviceable or non-serviceable plug). I can't rule out the IPR or anything under the HPOP (other plug and the bottome of the HPOP-to-reservoir gasket.

I will say that as much as I like the FRx it makes things very difficult to root around in there.

Even though there's oil in the forward portion of the valley from the HPOP fitting leak I didn't see any ripples from drops and it didn't look like it was flowing to the aft drain hole but this wouldn't be the first time I was wrong.

One interesting thing I did notice is that on the pasenger's side rear there were some wet drop-sized spots on the downpipe, hoodliner and a couple of other things in that area. Would that point to anything I should look at?

 

I was wondering if someone was ever going to answer the question!
