Engine switch out.
Did a leak down test on all cylinders today. most around 12%, one at 18% and one at 20%. Hooked up air line direct to each cylinder and rolled the engine over with 160 psi and "blew" any debris out of each cylinder, after that, all "leaked" around 12%. Then I started in on my version of a remote filter. I gathered up the necessary parts at my local "pull-n-save", then modified it to take -10 AN fittings and Teflon lined, steel braided hose. Hopefully will drop it in tomorrow.
Where are you getting your fittings from ? Haven't seen them in that color yet...natural lol.
The Teflon hose and fittings are from Aeroquip. I pulled everything off a 1998 F150 and then cut the tubing off the "manifolds". Then a machinist friend of mine milled them off flush and bored them to accept 18X1.5 fittings. He actually had to lathe each fitting to accept the o-ring and counter bored a small lip on the manifold to accept the o-ring. He did this as he didn't feel there was enough material around the bored hole to accept a pipe thread fitting without the risk of splitting or cracking the manifold. When I received them back, I spent some time with a Dremel tool and some sanding drums smoothing out the oil passage as the milling left a noticeable step that I felt might impede oil flow. One thing I'm puzzled about is the hole in the front of the "adapter". It is threaded as if to accept a sender, but not drilled to actually intersect with the oil passage. The manifold is threaded and drilled into the oil passage. You can see the "hole" in question in the photograph I posted.
It's not drilled through, that's strange. I fortunately do have the factory remote oil filter set up but will have the hoses replaced at a local hydraulic store (rather than buying Dorman) that does them for Fords, Chevys, anyone and made also out of better quality hose to.

Yea, that empty port is for a alternate sender sensor. No thru hole on those, they do the ciphering much like the CHT sensor (temp of block vs fluid). You don't have the HVAC fluid cooling block, most do w/remotes. Otherwise the coolant block (oil cooler) would ported in such a way that antifreeze coolant flowed thru the block as well... to assist in cooling. A neet little feature that some of our trucks had originally...tow package and stuff.
But yea, there should be another sender port on the back of the block. Set up the same way. Anyway, that's what's up with that empty port front side...unless of course you have it on backwards. I'm not sure that's possible?
Yea, the tough part is clearing frame rail with your fittings. Not tough really, - some forget to consider that lol.

BTW fluid stream sensors were completely phased out for the 5fours in 99, except for that one which your referring too. Came standared from 97. No more sender leaks.
The 4sixes weren't phased out until 01..completely anyway.
