Captain Obvious Posted February 1, 2020 Share #109 Posted February 1, 2020 Yeah, I'm not sure now. I took a quick look at some old pics when I took my 83 apart and the TVV is up in the thermostat housing, so my pic with the notes on it is wrong (in at least one area). I'll take a deeper look into my old pics when I get a chance. I do think the long snout sensor is for the EFI though. It fits into the dry thermowell near the back of the head. The beveled nose is supposed to bottom out in the hole for good thermal contact. Link to comment Share on other sites More sharing options...
Av8ferg Posted February 1, 2020 Author Share #110 Posted February 1, 2020 Okay, we’ll I just removed it from the thermostat housing. I guess the PO had stuff in the wrong place. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
siteunseen Posted February 1, 2020 Share #111 Posted February 1, 2020 What goes in here? Maybe the vacuum switch? Link to comment Share on other sites More sharing options...
Av8ferg Posted February 1, 2020 Author Share #112 Posted February 1, 2020 What goes in here? Maybe the vacuum switch? It appears to have a hex plug in thereSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Reptoid Overlords Posted February 1, 2020 Share #113 Posted February 1, 2020 My '82 housing had the TVV in it. 1 hour ago, siteunseen said: What goes in here? Maybe the vacuum switch? I wish i took pictures from before I removed that engine from the car. I probably am totally wrong, but I want to say that the valve cover breather goes into a fitting attached to that, as opposed to the earlier valve cover breather to throttle body.

Reptoid Overlords Posted February 1, 2020 Share #114 Posted February 1, 2020 eh nevermind, maybe from one of the coolant lines from the water jacket on the other side of the block? Link to comment Share on other sites More sharing options...
Av8ferg Posted February 1, 2020 Author Share #115 Posted February 1, 2020 I think this might be the accurate configuration. BTW, the large one is the thermo time switch because I won’t fit in the head location. This set-up looks to match the publications.

Av8ferg Posted February 2, 2020 Author Share #116 Posted February 2, 2020 So after some research in the 1982 FSM (same year as my engine). The thermostat housing has an extra sensor. I’ve circled it in the photo below. This sensor is connected to the blower fan that goes over the valve cover which attempts to cool the intake to prevent the hot start problems these motors have due to exhaust manifold proximity. I think I’ might just get a 280z housing and sell this one online or just leave it disconnected because I don’t intent to use the blower.

siteunseen Posted February 2, 2020 Share #117 Posted February 2, 2020 This is off a '79. Very different it looks like? This one didn't have injector fan over the valve cover. Link to comment Share on other sites More sharing options...
Av8ferg Posted February 3, 2020 Author Share #118 Posted February 3, 2020 This is off a '79. Very different it looks like? This one didn't have injector fan over the valve cover. Interesting that there were so many minor changes. I discovered while researching this that ZX series cars had many more small changes than the 280Z series. I’m going to my yard with the three 280z’s and a the 240 this week. I’m going to grab a housing out of there. If anyone has a request, please let me know. These 4 cars are mostly untouched so it makes for a great place to get hard to find or expensive parts. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Av8ferg Posted February 10, 2020 Author Share #119 Posted February 10, 2020 So today was the plan was to get my oil pan cleaned up, painted and installed on the engine. Many thanks to Wayne on the forum who graciously donated an oil pan to my cause. He told me he donated oil pan from a 1977. I need a new pan because mine has some serous dents and what I thought might be a small penetration, from the yard banging it around. So when I was out cleaning these oil pans this morning I noticed that the ZX will is significantly different than the Z pan. I was wondering are there any serious compatibility issues that would forgo me being able to use this Z will pan on a 82’ F54 block if anybody knows please let me know before I sand, prime and paint this 77 pan. thank you. See pics. 77 on left 82 on right. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
