Wanted to close this out with a final pic of the results. Taken in pretty much full sun so has a little reflection on it but I'm super happy with results. Even took the opportunity to get the right push rivets (realized after the initial install the PO had used interior ones) and I refreshed the metal clips on the bottom.

Love your license plate. I bought my 240 from my son when it was no longer able to provide him with reliable transport. From there I restored it. The license plate I got was DADSON.

Richard that's awesome. For the license plate when I first showed it to my wife she jokes around and says most people will think it's farty not forty

Sending you a PM about the tach. ☺️

Not to sound ignorant, but isn't that a seatbelt mounted to the side rail...?

Jarnved is in Denmark, In europe we had the 240z with original 5 speed gearbox! (Fs5C71 A or later B ) I once had a 240z original Dutch car (Netherlands) and it had the orig 5 speed standard. (Fs5C71B) That gearbox (and diff! 3,9:1 ) is now under my usa spec 240z. (got the orig parts as spares on the attic)

I want my car to be original.

That looks to be a great combo you have of 3.54 and 5 speed. I have a 5 speed and both 3.9 and 4.11 R180's. I am thinking of going the route of a 3.54 myself. I am running too many RPM's on the highway for my liking.

Not that glossy.

New treasure! 3 Mikuni 44 PHHs. I bought these on Yahoo! Japan back in December. Jesse Streeter helped me get them Stateside and I had them rebuilt by Taka at Kyushu House, who moved to Houston in the middle of the rebuild, hence the delay. They look fantastic. The manifold also looks pretty good considering it was pretty beet up when I bought it. It had no linkage and needed to be vapor blasted, but there are very few imperfections. Just some putting on the surface that mates to the header gasket. Can’t wait to get them running.

p.s. we used to build vent filters for our vacuum pumps that were about 8 inch lengths of two inch pipe packed with stainless steel wool. The steel wool collected the suspended oil and let it drain back in to the vacuum pump case, while the "cleaned" evacuated gases could exit. The same basic concept as the steel wool in the block side port in the Datsun blocks, I think. If I was going to run a vented valve cover I'd build something like that, concept-wise, to keep the area cleaner. It would probably be ugly, but might be effective.

If you want to avoid the fumes you'll have to run a closed system, like a PCV. So any vents under the hood won't work. Or you could run the vents to an area that is clear of the cabin, maybe all the way back the rear of the car. If you run a closed system it needs to be properly balanced so that you don't have high air flow through the crankcase pulling suspended oil out before it can settle. I've been hanging out on a Ford truck site and people get on there all the time talking about how they're pulling like a pint of oil a week in to their catch cans. Maintaining their catch cans turns in to a full time job. I think that the catch can system designers might be designing their system to pull a lot of oil. The people that have them want to see stuff in the can. If it's empty they'll think the can is not working. Even Ford has jumped in to the "upgrade" game but their system has to meet the PCV needs. It's more complex than the typical shiny metal can aftermarket systems. Interesting to study.
