Those wheel cylinders look like our PVC valve!!! That is going to be one nice M43 when you get finished.. Awesome work Zout!!

I have been tempted to go to our parts trucks to see if I can rob one there. My guess is anything we have on hand would likely be in the same shape. The test on those is if they rattle when you shake them. Most folks miss that there is a PVC valve in all that plumbing as it sort of looks like a...

Yes. And they would have, except that we are dealing with a 12 year old rebuild that never got installed. In the ensuing time frame, the shop owner managed to roll one of his super high performance engines in one of his super fast vehicles off a rural dirt road and into an irrigation lake. It...

Dad has been banging it on the work bench when GD was not looking. She is right, not effective. We are making some progress with getting the crud out. We have one end unthreaded and we have picked our way down to the inner works as well as cleaned out the tubing in the rest of the PCV set up. So...

Another possibility is the rotor gap between the distributor cap electrodes and the rotor. If that gets to large, it gets hard for the spark to jump from the rotor to the plug wires. An improvement in spark might have overcome that for a bit. Worn distributor shaft bearings will usually cause...

To be really kind to a battery pack, one should charge each cell independently of the rest, but who really wants to do that. The very difficulties described in charging an imbalanced 2x12 volt series battery pack can be found between cells in a 12 volt battery. A parallel battery pack follows...

GD found the tube bracket and got it attached to the manifold and the tubes installed when she worked on it yesterday evening. Thanks on the heads up on the other locations. We discovered the PCV valve was stuck, so we have an additional take apart and clean project with a bit of the plumbing...

The 5 ton air pack rebuild kit has all the seals necessary to rebuild the M211/M135 Air-Pak EXCEPT for two small cups. We could not find any M211 series rebuild kits even aver a couple months of searching. The 5 Ton kits are available on eBay and we got ours for less than $50.

July 26 progress with engine reassemble. Carb and vent lines. Ghostdriver got a visit from her brother who just had to twist a couple of bolts on the thermostat by-pass. She had a near disaster that wound up only bruising her shirt. Discovered more cracked brass fittings that had to be replaced...

Hard to send pictures of something I have not picked up yet. As soon as the EUC's clear I will get them and post pictures.

Just submitted EUC's on a couple of M105a1's Colorado.

Yes, usually there is some indication of an attempt to fire. Backfire through the carb or popping out the exhaust. Still, you have gas at the carb, have drained gas at the carb and have put ether and perhaps gas in the throat of the carb. Given the air flow you have determined through the engine...

Wow, I have never seen a Pertronix setup, but I have heard about them. Neat!! If the distributor shaft tang is symmetrical, then someone has modified it with a civilian lower shaft. ~~~ You are getting a spark and it sounds like sufficient spark to fire a fuel charge. You have introduced...

True about the civilian oil pump. I don't know what his aftermarket distribnutor uses for a block attachment. There are a couple of pins along the distributor shaft and oil pump drive in the military set up. I don't know what the aftermarket distributor looks like, but if any of those pins...

m3751 I understand you are not rotating the distributor, but the distributor shaft. What I am talking about is the bottom end of that shaft. It has a tang that looks like an ordinary screwdriver that fits into the oil pump. That tang is not centered, but it is off set to one side. Even...

Ghostdirver is using pliers to hold the studs while she runs a die to clean the threads.

Todays photos. Manifold bolted on late in the day while it was cooler. Ghostdriver had to rob a few parts (manifold stud and some manifold locking nuts) off of some of our parts stuff. We left part of one of the studs in the old engine block.

m3751 You have pretty well gone over the things to check. I am puzzled by your ability to rotate the distributor 180 degrees. The military distributor has an offset tang on the end that can only fit into the oil pump one way. ~~~ One other simple thing to check would be to take off the top...
