I managed to get the engine to pop a couple times, and it was about that time that I realized that I had not yet hooked up the oil pressure gauge. So the positive is that the engine makes oil pressure, the negative, is I squirted some oil out the side of the engine. I have an oil pressure test kit that I need to hook up before trying that again.
Taking a break from the engine (I had actually forgotten that I owned the oil pressure test kit) I decided to start into the dash itself. I finished running the hand throttle and choke controls. Found the nut that holds the steering wheel on, and mounted all the gauges in the dash panel. That was pretty uneventful, but did require a trip to Princess Auto for some terminal connectors. Not that I need much excuse to zip on down to Princess Auto.Tuesday, 28 June 2022
Progress is progress.

Jeep m38 proving that things don't always go as planned.
If you've been around a while, you may have read my last update from April. (Right here)
I wound up purchasing a stud remover, and asking the stuck stud to come out nicely with it. Which it did, so that's a win, and I did get the head removed. Much to my surprise, the pistons looks great, the block had no surprises, and everything was generally in order. Well, except when I drained the oil.
The drain opened and started with green, followed by milkshake brown, then some actual oil, and then sludge. Lots of sludge. As much as I didn't want to, the oil pan was coming off. In it, I found a 1/4" of goo. It took a bit of time and some brake cleaner to get it to come out. Followed by cleaning up the pan and getting it spotless.I had to order in some more gaskets (note to future shade tree engine rebuilders, order the full gasket set at the start).
Ultimately, the oil pan went back on, the valve cover got a new gasket, and the head went back on with it new copper coated Fel-Pro gasket.I have a set of new spark plugs, and we're just about down with that easy head gasket replacement. Next I need some high-zinc oil, some engine flush, and that should be it. Hopefully.
The tunnel is a long one, but I can see some light twinkling at the end.

The Best Laid Plans...
Everything arrived over the past week, and I found a local source (NAPA) for copper head gasket spray.
Knowing that it's supposed to be pretty easy to swap out a head gasket on these Go-Devils, I dove in. Surprisingly, it went smooth through removing accessories and head nuts/studs (some studs came out, as expected).

Make sure it's in neutral
I had a few minutes out in the garage this weekend. My son was hanging around with me on Saturday, and he enjoys playing in the Jeep. Anyone with a kid will understand that keeping them occupied is the secret to getting things done.
The agenda item was pulling the fuel pump and replacing it with a new unit to see if I can fix my fuel issues that I encountered during my attempt to start the Jeep.

Yeah. Not good. |

So Pretty. |
Evidently Nate decided that while playing army man, it would be wise to play with the gear shift and ended up leaving in gear. I didn't think to check. Totally my fault, and not a mistake I'll make again.
So there you go, some freebie advice for the day, always make sure it's in neutral before bumping the starter.

Test firing the m38 Go-Devil engine
Why was it 2022 before I learned about how great these are? |
I started by finishing off the carb build, and plumbing in enough fuel line to get a small tank hooked up to the pump, through a filter, and into the carb. Sadly, the pump seems to be shot, but I have a new in box one to go in.
The carb took a bit of work, being 70 years old and all. The metering valve and needle did not want to come out. It involved a lot more drilling than a carb rebuild should require.
I put a bit of two stroke fuel into the carb, and used some starting fluid to get it to pop off once. It was enough to convince me that we have a viable engine. It needs some work to button it up, and probably a head gasket (coolant in the oil), but it turns over, has spark, and enough compression to pop.
And without further ado, a VERY short video of me pulling the trigger... so to speak.

Slow and steady Jeep m38 Progress
The longest journey begins with the smallest step. In my case, several small steps. Each one getting closer to a the goal.
The m38 has been getting some work here and there over the past few months, as I have time, and as parts arrive. I have confirmed that it has been converted to 12v from 24v, the Canadian Tire Motomaster 12v distributor helped confirm that.
The work has been minor, meaning, I haven't been too inclined to update here. So here's an update with a lot of small things.
Parking Brake
I knew the existing parking brake needed to be replaced. The backing plate was bent, and it was no doubt worn right out. In the very least the cable was cut. Using the brake off the spare transfer case, I tried out some evapo-rust. Colour me impressed. The drum, backing plate, and salvageable parts, came out looking like they just came off the shelf.Battery Cables
With a rebuild of the electricals required, the ancient, rotted, battery cables just wouldn't cut it. Using some 1/0 welding cable, lugs, and marine style clamps, I build a fresh set of cables. Fully soldered together at both ends. Along with building the cables, I stripped out all the wiring on the passenger side of the engine, as it was a mix of old, brittle, and corroded. It's ready for a new wiring harness. I've also installed some brand new spark plug cables in preparation for first fire up.
