Captain Obvious

Oh no! I guess when it rains, huh? I'm sorry to hear about the multiple calamities. I don't know how to estimate what the change will be to chamber volume with a .015 shave. Are you going to measure the volume, or just guess a reduction amount?

You sure are "lucky"! Hope that's the last issue!!

Wow. Down to the tendons pulling a valve cover!! Glad you got it all stitched up! You didn't have to drive yourself to the ER did you? I'm assuming you got a bunch of dirty "You idiot, not again!!??" looks at home, didn't you? I know I would.

Based on some prior super-secret discussions with @wheee!, I'm running a Denso 150-2066. I've switched pretty much everything over to Denso now.

I think that timing cover is fine. Those little lines are just imperfections from the original casting. I see you already sanded them off. Good... Non-problem. As for the hex plugs in the intake manifold... As mentioned above, they cast a cavity that runs the length of the manifold to distribute the recirculated gasses from the exhaust (EGR). But that cavity does not have any connection up to the intake runners because it was impossible to cast that way. So those plugged holes are the access holes they used to add in the holes between the shared EGR log and the individual intake runners. I haven't pulled those plugs or sectioned a manifold to see for sure, but I wouldn't be surprised if the holes they drilled up into the runners are different lengths depending on how far they are from the EGR valve. Just a guess on my part. In any event, they drilled small access holes up into the runners and then tapped and plugged the access holes below. And they thread-locked the steel hex plugs in place. I tried to take one out as well and couldn't get it out. I suspect a bunch of heat would make them easier to get out, but I was doing this on the car. Next to the fuel rail.

In fact, most of the compressed "air" dust cleaners are not air at all, but are usually compressed refrigerants such as R134 and R152.

Agreed. I love the dichotomy of the one old style braided jacket hose still in there with all that new stuff. Highlights the "resto-mod" style of the build.

Haha! Yeah, that could go either way! And you might not want to know which way. I wonder if you had welding beads flying all around enough that you got one stuck to a valve guide... Who knows where else they landed??

Haha! Yes, black with yellow. not white. Sorry. That's what I get for relying on memory. Glad I got the starter location correct at least. Pull that small black with the yellow stripe off and then turn your key to START. You should hear the fuel pump run.

I'm not far from Strafford. And that's not too far from Devo either. LOL!

Disconnect the small black wire with a white stripe. Should be a spade connector, and it should just pull off. No tools required. Don't let the dangling B/W wire short to anything. Put a piece of tape over it if you aren't confident.

Uhhhhh... That's not the starter. The starter is the other big electric thing behind you below the battery.

Absolutely. If you travel to the Northeast, make sure I know about it!

No, I haven't taken any measurements off mine. I know I popped two of them out enough that they could have spun 180 degrees. I don't know for sure if they really did spin or not. And the two that popped out far enough that they could have spun were not on the same piston. So I know with certainty that both bolts are in their original positions on four pistons and at least one of the two bolts are correct on the other two pistons. That's all I got right now. I ain't skeeered. Haha!!

Sweet. Looking forward to the first test drive. Good thing you remembered to tighten up the oil pan bolts!!

The ITM gear does have the marks. Reptoid Overlords confirmed that earlier. Here's my current list. Yes Timing Marks: TRW S462 - pic from ebay has the marks Beck Arnley 025-0266 Pic from ebay has the marks ITM 053-90400 has the marks (note this is a full kit) (Confirmed by Reptoid Overlords) No Timing Marks: Melling - Pic from rockauto shows no marks on back OSK does not have the timing marks - (Confirmed by Dave WM) Federal Mogul (Sealed power) - pic from ebay shows no marks on back One of the brands I haven't yet determined is Cloyes. Anyone seen a pic of the back of that one?

LOL!!

The restarting procedure sounds good to me. I made up a little remote starter button that I use. Push button switch with two pigtail wires. One of the pigtails has a female spade that plugs onto the starter solenoid (after disconnecting the original B/W wire) and the other pigtail has a clip that attaches to the battery terminal. Cranking that way (with the rest of the car completely off) produces motion without any of the other ancillary functions like spark or fuel. Fuel pump doesn't run, and the ignition and FI systems don't get power so they sleep through the process. Make sure the car is not in gear. And as for the thing about the OSK timing marks, my mistake. I thought you had said that the OSK did have the marks, but I guess that was the voices in my head. Make sure the car is not in gear. Oh, and make sure the car is not in gear.

Carp. Well at least you caught it before it did something unrecoverable. You must have pretty good ears to have heard that issue so early! Clean room... That's what I need.

Right, it doesn't care. And probably neither will anyone else. I've been in to multi-thousand mile engines recently and the timing marks still looked good. That said, if I get the option, I'd like to have the marks. @Dave WM, I thought you had said earlier that the OSK had the timing marks. Is what you got different than a pic you were shown prior?

Yuck. No fun. I don't get the weld spatter. Anything else you think of that it could be? I mean, I gotta admit that nugget on your valve guide sure looks like a weld spatter bead, but honestly.... How? Really? Still hot enough to stick there down inside on a valve guide? Are you sure it's metal? Is it magnetic? I'm going to build myself a clean room when it comes assembly time.

The Canadian Tool Exchange visited last night!! Thanks @240260280!! And even though I'm jumping the gun, I just had to try out the ring pliers. Seem to work just fine: And speaking of such things... The Ring Fairy made a recent visit as well:

I thought it was "M sub f".

I've been into two later model ZX motors in recent past and they did not have gaskets on the tensioner. I don't know about earlier years. As you mentioned, it could be something they dropped somewhere along the way. So I took a good look at the tensioner and guides from my 83 motor... There were no markings that I could find on the tensioner, but I did find some markings on the guides. tight side side (left). Had a KR inside a circle. Did a little web searching and came up empty: The slack side (left) has a marking from Tsubaki. They are an old Japanese chain company which makes perfect sense: I cannot prove it, but I believe these parts are original from the factory.

I'm no expert on the finer points, but I do not think there was a gasket behind the tensioner when that motor left the factory. I believe the gasket behind the tensioner is an indication that someone had replaced all that stuff in the past. Do you see any manufacturer marks on any of the parts? I'll look the factory stuff over from my F54 tensioner. If anything, I would expect to see either a Nissan mark, or a Hitachi mark on my original stuff. I'll check.
