I mentioned this in my HMMWV rebuild thread but don't think anyone noticed, so putting it out here. I've noticed what appears to be a new tiny bit of weeping between the head and block at the front left corner of the motor. Tiny, tiny bubbles when it's running. I don't think it's using up...

Yep Varibulls Betsy Bell, purebred champion bloodlines; seen here in attack mode

Got more work done this long weekend. Removed the mechanical oil gauge, after becoming confident in the accuracy of the new OEM replacements. Tightened lots of fittings. Notice my valve cover gaskets were leaking, perhaps because the bolts were quite loose. Also had to tighten scads of...

Pulled the mechanical oil gauge Friday, after gaining confidence in the new electric sensor and gauge. Finished the steering pump RnR yesterday late, was a two day job working off and on. Took a while to clear the air from the lines, but she's steering well now. Have a few more things to deal...

Got the alternator and steering pump off. Will r and r the pump tomorrow morning and get the reservoir put on the new pump. Thanks to TheCaptain and AnotherAhab who came and helped. Bulldogger

Well folks, dilvoy wins the award! The bypass hose between the top of the water pump and the bottom of the thermostat housing had a failed hose clamp!!! I discovered it when replacing the hoses as he suggested. I cleaned the body and dried it, then sprayed the pump body down w talc based...

Color matching, finally! At the risk of disappointing AnotherAhab, I painted my tan soft doors to better match the rest of the vehicle. It is the Rapco CARC substitute spray paint. Took a lot to cover up the tan. Had to order more and wait to do the last door! Bulldogger

It doesn't seem to be the hoses but that is a cheap and easy thing to try. I'd meant to replace them anyway. I already did the larger coolant hoses. Ill try that and report back later this week. If it doesn't work, my weekend has planned itself, I guess. Bulldogger

Thanks for the comments gents. I took some pictures in case they help. The wetness is around roughly the top half of the pump. I can't see anything much down below the shaft. Couldn't spot the weep hole. It is starting to sound like an RandR. Bulldogger

Now a leaking water pump gasket? I'm starting to lose coolant and now seeing a seepage puddle beneath the HMMWV that's just come to be in the past two weeks. Based on wetness on the engine block, it looks like the gasket between my water pump and the adapter plate is leaking. Is this common...

I rode that ten years ago on my shovelhead going out to visit relatives south of Chincoteague. The bumps of the bridge weren't too bad but it was 30mph crosswinds the whole way back and I HAD to be at work on Monday and dog sitter was leaving Sunday day afternoon. It took 8 hours to do what is...

Installed new oil pressure gauge and sending unit, courtesy of Erik. Working well. Still have the mechanical gauge plumbed. Will run it a few more days before going back to stock. So far so good. Bulldogger

Well gents. The problem seems much more clear now. I plumbed a manual pressure gauge and did some driving. Took a little more time as I gathered fittings so's I could have both the factory electric gauge and new manual gauge connected at once. After some highway driving, the dash gauge would...

I haven't made time to install the mechanical gauge, but just changing the oil to rotella 15w40 and a new filter has doubled the idling hot oil pressure. Funny what the right (or better) components will do. I will still put a new gauge in but so far things are definitely improving. I'm glad for...

orgnal, the trans doesn't drop down a gear when I floor the pedal or when hill climbing, etc. The kickdown switch "clicks", but I haven't had time to test it for continuity. I have verified the kick down solenoid is in place at the transmission and is connected to the other end of the wiring...

There is nothing wrong with painting your truck how you want it, and I think anything that is pro-military in nature is sorely needed in our society right now. PLEASE PAINT YOUR TRUCK IN MILITARY COLORS! Paint your car, your house, your kids in military colors! (OK, maybe use something...

On the suspicion that my HMMWV has less than perfect grounding, I went ahead and put on my homemade grounding harness last night. First thing I noticed digging around is that the ground lug above the fuel filter was loose. This is the ground lug that on the inside of the dash happens to...

Installed my homemade grounding harness last night. It seemed to positively affect the accuracy of my oil pressure gauge, at least in the amount of time I had to test drive. Time will tell. Have to get the gumption up to replace the weeping steering pump next, and fix the transmission kick...

DatGuyC, the fan is locked when the motor is off. It only seems to kick on high speed when the vehicle is moving though. I installed my grounding harness last night, and that included a ground to the EESS, so I will see how/if her behavior changes as I drive her. I took a 15m test drive...

Thanks gents, I appreciate the feedback. I can easily hook up a mechanical gauge, and happen to have more than half the setup handy from a motorcycle diagnosis project earlier this year. I am happy to change to 15W-40 RWH, especially considering the advice comes from you. I bought it by...
