Thanks everyone for the help...got back up and running yesterday.
When I do things like this...I tend to snowball into doing more.
I went ahead and did the full HPOP reseal kit from Guzzle, no more leaks. The "non" serviceable plug has/had me a little worried. I used an oxy/act torch to heat the area up to the 4-500 degree to get the loctite to give up. It came out easily and the threads looked fine inside. The new plug didn't go in the easiest (i.e. by hand). It was pegging past the 75 in-lbs on my bar torque wrench just going in (but nothing that felt like I would be stripping threads at all). So I used a 3/8" drive, and light hand tightened it up until the shoulder hit the base like it should.
Other things I did while I had it apart:
- Full Fuel Bowl Reseal and filter from Guzzle (good thing I got to do this, my fuel filter was dark grey with crap :lookaround
- New HPOP lines from Guzzle (gat damn lines are expensive, and none of my local hydraulic shop could get me anything without going to JIC fittings)
- New glow plugs (been needing to do these a while)
- Foil delete: not because I want more sound, but since the foil was dirty and had seen some better days. That stuff was a b*tch to remove. Sanded it with some 500 grit after.
- RiffRaff FRx and HPx (had them sitting around waiting)
- CCV mod
- 50 cent mod
- Cleaned the EBPV sensor and tube out real well. At first I couldn't even get a weed whacker wire through it, it was that gummed up. So hopefully have a cleared up tube and sensor should help a little.
- Cleaned the ever living HELL out of everything. Everything that came off/out got a thorough cleaning and scrub down until it looked damn near new. I'm OCD about this kind of stuff.
I've still got to actually drive it around to purge the air out of the oil system. But other than that I should be good to go! I'll still check like a hawk to make sure all seals are still holding. I'm a LOT more knowledgeable about the truck now which is nice (i'm a Mech Eng).
Thanks again everyone!
