I have a hard to find coolant leak, losing a gallon every 50 miles. my observations. only happens while operating. only visible liquid is down wind (while driving) of the overflow tube. coating the right axle and leaf springs. no other trace above that. system holds pressure. After...

I'd love to see some pix. I have a navy m38a1 myself this is mine, USS Independence

I read up a bit on Tcase gear oil. The info from mobil and a few other sources isn't what I was expecting to hear, or what I have been doing, so here it is. I have been using 75-140 in tcases, figuring thicker is better for things that get hot. Jeep specifies 90w, for climates above 32f. I...

Any comments on the Tcase temps I took a few posts back?

I almost missed the deadline. I had my eye on the event months ago, and registered in March, but it was pure chance that I didn't put it off and miss the deadline. I appreciate the organizer's difficulty with something like this, planning hotel capacity, stopover capacity would be a nightmare...

I ran a test on Sat on 2 trucks, an m38a1 and an m715, hot day so a good day for a test. Ran the trucks for 30 min at 40-45 mph. ambient was 95 deg. M715 Block-163 deg, 4 speed- 168, tcase-189 M38a1 Block- 160, 3speed- 165, Tcase 169 I can see where the Tcase on the 715 could go over...

I think its about as ready as I know how to make it. Took it on a shake down of 35 miles, I'll do a stress test in hot weather this weekend. I looked at the tcase, didn't seem unworkably hot. I do have locking hubs on the front wheels, which takes some of the load off the tcase. For...

I am going to roll my M715 for a part of a leg of the cross country convoy in September. I am picking up the group in Charlotte and rolling with them to GA. Making a truck ready for long day road miles has been an interesting exercise. You look at things differently. I replaced the single...

nice work...... well Oli, your in up to your neck now.....

I couldn't let it go. I studied the carb that doesn't work. I looked at the carb manual to see what could possibly make it run rich at idle. I came up with a theory- what if the vacuum passage for the accel pump that passes near the idle passage was drawing fuel from the idle passage into...

Very Nice. Doing whatever it takes!

so here is the conclusion to what turned into a nice discussion The problem that prompted all of this- The truck was running fine, and then developed a rough idle, not seemingly corresponding to anything, but came on rather suddenly. At speed and under load, it seemed about like normal...

OK, some progress, but now questions. Mounted an m16 rack, the TM shows it behind the seats, but I like it better in front. Back to the gas in the oil problem. I have run the engine for about 30 minutes, a dozen or so times of turning it on, shutting it down. There is a...

John, email them to dougimes@yahoo.com Ill post some of them here

Ill trust you bcowanwheels, that line looks like a bugger to get off. Any tips, there is only about an inch between the top fitting and the fire wall. I cant even touch it.

Whats everyones favorite source for parts? I need an exhaust manifold gasket.

PB Blaster actually. you can get it in the autoparts store. amazing stuff, not quite as good as Kroil, but easier to come by.

beautiful day to work on trucks . Sunny and 60. Took the fuel pump off and checked the integrity of the diaphragm, Its not leaking, and definitely not leaking gas into the oil, so at this point, I have good explanation. It will happen again I suppose, I'll be watching for it . While...

Update- Checked transfer and 4 speed, levels good Checked propeller shafts and ujoints, lubed Checked oil , level good and looked clean, but something not quite right. Drained it- It was the consistency of the stuff you drain off from a can of kidney beans. It was hard to tell, but I...

Hey John (poof). Here is one of my favorite shots from farm days. I give my dad grief missing the driveway whenever I can. (John did the paint and markings last summer). Do you have photos of your work on the vehicle last summer? I am putting together the MV show signage. History the...
