Not much of an update right now, finally got the temps down, 100+ degree days takes a toll and work has been crazy lately, catching up after the covid slowdown.
My son and I got some maintenance time in today. We greased up all the zerk fittings on the car, there are 23 of them. Showed him how to check tie rods, kingpins, sway bar mounts, etc for play and looseness. Only iffy thing we found was the driver's side upper shock bushing had a bit of play. Since relocating that mount is on the list to do and that requires different shocks it will be addressed. Taught him how to remove the hubcaps, check tire pressures and reinstall hubcaps. I know it seems basic to us but hey when was the last time you saw a new car with hubcaps anymore? We also played around with my IR gun and discussed how the cooling system functions. We also went over camber, caster and toe as well as bumpsteer. These jobs tend to run long since almost everything is a learning opportunity for him so we go into the why things work alot.
I know the project is going somewhat slow, but I only get him one weekend a month and we squeeze in what time we can on it.
This worked out better than I had hoped, he's been enjoying it so much he signed up for collision repair class this year at school.

Spent some time with my son on tearing down the 230, had to drag him away from Band of Brothers to do it though.
Got all the studs but two out of the manifold mounting area, going to leave those two for the machine shop as I already broke off an easy out in each and managed to remove the broken parts, which if you've ever had to remove a broken easy out you know how fun that can be. So my son learned some valuable information with that, first don't break an easy out, second how much fun it can be removing the broken one.
Pulled all the external stuff off of the distributor side, except the oil fill and dipstick tubes. No real issues there.
Got the plugs out, some of them really did not want to come out, used Kroil on them but even so number three was a bear. All of them had gaps in excess of .045" some well in excess. Wonder how well it ran? Number six looked a bit rich but the rest looked ok colorwise. This kind of thing will tell you how well it ran aforehand.
Pulled the head off, most of the head bolts came out ok, one or two were a bit reluctant but came out. Solid copper head gasket on it, no copper coat or sealant that I could determine, head popped off with no issues whatsoever, one moderate whack with a plastic headed hammer and the head moved. No idea what brand that head gasket was, couldn't see any name on it. Not planning to reuse it so it doesn't matter, might turn it into wall art for the garage. Some of the coolant holes in the deck were a bit goobery. It was interesting to see where, in the chamber, the carbon build up was. Tells a bit about the thermodynamic characteristics.
Cylinder walls barely had a ridge, just enough to barely catch a finger nail. Might have just been carbon build up, haven't looked close at it yet. Might bust out the KaBar to see if I can scrape off the carbon or if it's a ridge. Both the KaBar and I have found other uses for ourselves these days, lol.
In the tappet picture above you can see some of the valves are stuck. I put some penetrating oil in through the ports three or four times since last weekend. Once we got the head off we squirted some more penetrating oil in thru the opening between the deck and the open valve. Then hosed down the valve stems as well. the objective being to loosen up the carbon and rust. I got all but two loose with nothing more than some penetrating oil and a plastic faced hammer. I will work on the other two some more tomorrow, they are soaking in penetrating oil right now.
More as it happens.

More progress today, of a sort. Started taking out the valve train. Had a couple sticky valves that repeated applications of many different penetrating oils didn't affect. Started at the front of the block, working aft. Got to valve 7, of 12, when I dropped a valve keeper. Heard it hit sheet metal, didn't see it. I do have a sheet metal drip pan under the engine, no it didn't land there. So, I drop the oil pan, which was on the list of things to do, but not right now. Such is fate. Keeper is in the pan. I see some minor sludge in the pan and run my fingers through to see what there is to see. I found Blackbeard's treasure. Number 6 cylinder skirt in the pan.
