It cooled down a bit here in Phoenix, so time to start to put the M38A1 back together. I just had a quick question. I had the machine shop install Hardened exhaust valve seats and valves. The new valves don't use rotors on them it is just the keepers and retainers. When I install the valve...

Got the motor tore apart. Already got the head at the machine shop Things are looking good. Today I pulled the transfer case and transmission out. They are going to get tore down and new seals and gaskets and anything else they need. I still need to pull the block out and load it into the truck...

I think I am going to start calling around to machine shops this week and start getting a price on machine work. Then I can build it in my garage as money permits. Rings, bearings, seals and gaskets, valve parts and timing chain. Price wise it should not be to bad. Big cost is going to be the...

So I did a wet compression check on the A1 and I got a good 119 PSI in all 4 cylinders. That is 9 more PSI than dry..... From what my vacuum gauge says that I have a sticking valve and worn valve guide. I like to condemn things to quick sometimes. What do you guys think? Rebuild? Anymore ideas?

So today I got a chance to work on the M38A1 for a bit. I hooked up a vacuum gauge to the full pump and it held 20 lbs of vacuum so I don't think it is leaking. I ran the engine to operating temp and hooked the vacuum gauge and the needle was jumping back and fourth between 14 and 20 looks like...

I have new lines installed on the jeep but no fuel pick up So right now i just blocked off the hole for it and ran a rubber fuel line from the bottom of the tank to the fuel pump with a filter. I ran out of patience waiting for the fuel pick up. So I know the fuel lines are good lol. As for the...

There is allot of good info here Thank you for you help makes it easier to trouble shoot. When I bought the Jeep I replaced the air filter element and oil. As for the carb I rebuilt it and I made a little cardboard tinplate for the float so I am about 99% sure that it is at 9/64 I double checked...

I changed the oil using 30W oil like the technical manual says installed the cab and drove it around. By the end it was not smoking as bad but still smoking...... I'm going to check and see if the oil has any gas in it tomorrow. And if it still acts flooded when I try to start it. Has anyone...

So tonight I pulled the carb off and looked down into the intake and I can see gas pooled up in the intake were gas is leaking out of the carb. I took the carb apart and cleaned it. Tomorrow I am going to change the oil and install the carb and see what happens.

The fuel pump is a rebuilt that i just got back form kaiserwillys.com about a week ago. And I have only ran it twice with it installed. The one before it was a brand new CJ5 pump. Is there anyways to test to see if the pump could be leaking fuel into the engine? I am going to change the oil but...

Here is something I have not dealt with before, I checked my dip stick and noticed my oil was level was high. So I drained some oil out. When I drained the oil it was thin and smells like gas..... Now that has me thinking. Every time I start, it it acts flooded (takes fore ever to start and...

Well that gives me a reason to rebuild it. I am waiting for my cylinder leak down tester to come in the mail and then i can see if it is valves, rings or it still could be a leaking head gasket that is letting oil by when returning to the block. Thanks for ideas.

So I started it up this morning and looked it over more. I did not see any bubbles in the water. Oil Psi at idle is about 12 psi when i rev it up the pressure hits about 30 psi. I TQ the head down to 65 FT LB adjusted the intake valves while I was there. The engine runs about 185 190 degrees. At...

I can smell gas on them but they are oil soaked also. Running temp was about 190... and maybe 40 50 psi while driving. I will look again tonight. I seam to have good oil pressure so makes me think the bearings are good. I will re torque the head right now and we will see if they were off at all.

Blue smoke, oil in exhaust, oil on #1 plug other 3 plugs had burnt oil. It is defiantly burning oil..I do have a bunch of the manuals I downloaded them when I first got it. As for the bubbles I went to go look and I popped the hood and noticed my oil pressure line to the oil filter was rubbing...

So I got the M38A1 put together enough to drive around the parking lot. Took it out for a spin and the thing smokes like a chimney. Well I guess I am going to rebuild the engine. But my question is, are the military F-134 engines the same as the CJ5 F-134 as far as the internals go? I would...

Thanks that is just what I needed. Someone before me cut the frame off right were it raises up were the bumper mounts so they could mount some channel iron as a bumper. :evil: every time I take something off I find something more messed up.

Could someone post up some pics of a M38A1 frame with the front bumper removed. I am trying to rebuild my frame ends up front. Someone cut them all up it looks like. Thanks Aaron

The ones I see on eBay go for a arm and a leg for shipping. I have a number to a guy that sells Willy's jeep parts here. I just need to find it and see what he has. Is there any info out there on repairing the mechanical regulator? Thanks for the help.

I am watching a used mechanical regulator on Ebay but I don't want to spend 60 bucks with shipping and get it and it not work. Is there anyway to bench test them? I am collecting all the parts to convert it back over to 24 volts. I don't see as point to have a M38A1 with a 12v system I might as...
