Yes, just the one. Be sure to check the front vent hose as well if you have a 4x4.

 

Roger that.

Transfer case trans fluid change and front differential gear oil change are on my list of to-do's. I'll add that front vent and extend it, too.

That differential...no filter in it, just drain and refill with Mercon V, right? Wasn't there some special Ford fluid for that to keep it from exploding?

 

No filter, but use gear oil of the proper weight. I would have to look it up, but it is not Mercon V. Unless you are thinking of the transfer case, but that changed fluids too.

 

Front diff is same as rear? If so that is Mobil One 75w-140w

The transfer case calls out transmission fluid, but I'm remembering some thread about a special fluid in there for the heat so it doesn't blow apart...can't find the details.

 

Front differential: 75W90

Welcome to guzzle's Front Differential Maintenance Web Page


Transfer case: XL-12 now (not Mercon V ATF)

So the front differential is a bunch lighter than the rear differential gear oil?

XL-12, that's it

Thanks!

 

I added 4 quarts of XL-12 to my order.

The transfer case takes 3.8 pints, so that should give me enough to change the fluid, run it a bit, drain and fill again. That should make a simple flush

Just under $8/quart.

Hopefully be able to fit it in tomorrow's schedule, too.

 

Yep. Takes almost 3 quarts to fill to the bottom of the hole.

 

I was having thoughts about whether you had a mechanical gauge or electrical...you might want to run it out of that IAH hole.

 

See what I see?



Apparently when it was laying flat against the alternator housing, it must've rubbed- possibly when I leaned on it

There is actually a bit of wire barely showing. I couldn't quite pick that up on my cell phone camera.

Well, it has some black tape on it until I can pick up some liquid electrical tape.

Hopefully that is the only problem with the charging

 

Well, after all this, I STILL have a substantial oil leak

I worked from the bottom with towels and brake cleaner to clean up old oil and junk on the motor and oil pan and stuff. I found a fair amount of wet oil on the FRONT of the motor

So I began climbing, crawling, stretching all over to narrow it down.

It seems to be rolling out of the front of the valley. To test this, I worked from the top with rags and towels to clean out the valley. I used a long screwdriver to put blue shop rags into the valley and move then around, then a piece of wire with a coiled end and pointed tip on it to stick and retrieve the rags.

Then I put a fresh rage just in front of the spider to separate the turbo oil area from the HPOP oil area.

That rag stayed dry through a start and short drive, but oil began to build up in the front part of the valley.

I had tried to clean the HPOP "non-serviceable plug" before the test but it was very difficult to reach. If it is leaking, it is a weep (or on the bottom 1/3 that I can't see?)

The hoses and new fittings are dry. I wiped them before and they were still bone dry.

So now I'm thinking:

1. IPR
2. Non-serviceable plug
3. HPOP gasket
4. Tear in the fabric of time and space

In that order.

So tomorrow after I pick up the fuel pressure regulator rebuild kit and other parts, I will move the AIH relay, unplug multiple sensors, disconnect fuel lines, move fuel bowl out of the way or remove it completely to rebuild the FPR and make room to get to the HPOP and inspect it with lights and mirror and maybe even my little inspection camera.

I *hope* it is the IPR (orings). If so I can pull than and go to Allied Seal and back in under 2 hrs and get it back together rather painlessly.

If it is the non-serviceable plug, then I'm into pulling the HPOP, waiting for both HPOP gasket and the non-serviceable plug parts before I can fix it.

Here's a before pic of the HPOP, when I had it torn down to replace the fittings and hoses. See anything of concern/interest?

 

...over to this new HPOP/leak thread

If I put it in here, nobody will ever find it

 

I no Ford spec's a different oil now but BTS & JW still use Shaeffer trans fluid.

 

I have 4 qts of XL-12 on the shelf waiting now

Thanks
