@Diseazd Guy do you know of a place for us to shop for Total seal rings? I haven't found a source for them yet.

Fuel recommendation for a '73 240z with rebuilt engine and SU carbs?
How many turns down are the mixture nuts? Are you sure its rich? Is the float fuel level correct?

Engine rebuild smoking
The fact that it didn't smoke at first but smokes more and more as it runs, makes me think they have self destructed

1971 HLS30-14938 "Lily" build
I was going to use a spring for the 180d bend in the tank vent line but I can't figure out the right search terms. Does anyone have a link to a proper spring for this purpose?

Of course!! I wanted to be sure you had documentation for reassembly

Engine rebuild smoking
So I don't want to get ahead of Ernest but I'll post up some info from today. I went and helped him get the engine out. We tore it down to the long block The intake valve stems were really clean looking. The exhaust ports looked really wet! It's a little hard to see in this picture. That is actually a puddle of oil in the exhaust port! This is actually liquid like oil that was seeping down under the gasket. Pretty much all of the ports had the same situation. The PCV hose was nice and clean. I would say all of this is coming from the bottom end and it's not isolated to one cylinder. To me that rules out a broken ring or bad ring indexing or something isolated like that. This is an issue across all the cylinders. I also don't believe the engine builder is going to be the issue. He's apparently been building races engines for probably 40+ years. If I had to guess, I would suspect the oil rings destroyed themselves. Possibly poor quality rings... Will be interesting to see what he finds when he tears it down

L20b Cody's Goon
I also took his spare tire mount apart last weekend and replated and painted everything. The chain was tough to plate! I really should have done it in the barrel plater and I don't have enough amperage for a part that big. So I had to do it in sections and that made it sort of inconsistent. But like Cody said it will be up under the car I also started on the door sill tin at Ernest's

On another note we have a matchbox dizzy for his car. It looked pretty pathetic, so I decided I would go through it and clean it up and make sure everything was free inside it... So I was trying to get the reluctor(?) off but was afraid to try to pry hard enough to make it move. So I came up with this. I use the center off another puller and a couple of paint can openers. Didn't need a wrench. Threaded off by hand Continued on with disassembly Pretty nasty inside So after I helped Ernest pull his motor, I made use of his Vapor honing cabinet The main body has a lot of pitting but not much I can do about that. It does look a lot better though and once it's reassembled, it aught to be reasonably presentable

L20b Cody's Goon
Machine shop didn't seem concerned about the indexing. Just suggested we run it. I don't know that I have a lot of other options. They're not going to do anything about it. So I guess we'll run it and see. The only other option would be to tear it all down and find someone else to check the balance on it. Disappointing but not surprising...

Nice clean looking install!

Z Restoration Progam
Yeah, you're gonna have to want it. It is a pretty car though. I would have to have a lot of money to be comfortable driving that car around. I know many high end cars really don't get driven much but cars typically like to be driven at least some...

That looks pretty blue!

Engine rebuild smoking
I guess another problem could be at the head gasket and maybe oil is getting introduced into the combustion chamber that way but that would tend to only affect certain cylinders and typically the water jackets are the ones to leak not the oil ports
-
Engine rebuild smoking
This was my line of thinking. That maybe it would seal up if you could load the engine some. Heavy engine braking tends to seat the rings better than just revving with no load. I figure, at this point it's "broke" so you can't break it

Engine rebuild smoking
It'll be hard to get them to make it right if they dont believe there is a problem... Is it possible to get a good video of the smoke and post it up? It's not an absolute that a good compression motor wont smoke. It could be oil rings or the ring gaps might be too closely aligned. Another option would be to keep moving forward. Get it painted and put some road miles on it and see if you can get the rings to seal better. You could also get a wide band and check the exhaust. Get the mixture dialed in. If it still smokes it's not fuel at that point

I think they make a special set of pliers to do it... I couldn't paste in an image... Google "safety wire pliers aviation"

75 280Z - Water Ingress From Hatch / Hinge Area?
The hinge seals are sandwiched between the hinges and the chassis with a small metal frame as a washer. They are custom made now and can be pricey. I don't think you will be able to see anything from the interior side. Might help to have the panel out though and try to pinpoint the leak with a garden hose

Parts Wanted: Lower Fan Shroud for 73 240z
That also appears to be what carpartsmanual shows too
-
Datsun-240z Vs Fairlady-z432
Yes, typically they are wired to each other Sometimes they are all wired in series. I don't know if the bolts are available already drilled. I know many times racers will drill them themselves to make safety wiring possible. I don't know historically but many modern racing classes require some level of safety wiring

Parts Wanted: LD28 Crank Wanted
I have one, not sure what they're worth in todays market...

You would think oil in the exhaust would taper off as it burns out, not increase with run time. Does the head have new valve seals?
-
Impossible Oil Leak?
Does your crankcase/ pcv system work correctly? The oil caps are supposed to have an O ring. At different times they were integral to the cap and then the valve cover
