LeonV Posted January 22, 2020 Share #98 Posted January 22, 2020 You can also take this time to measure piston deck height. Put a straight edge on the deck, turn the crank until the piston rests on the straight edge, zero the indicator and go all the way up. Place the indicator along the wrist pin and the straight edge intersecting the wrist pin. 1 Link to comment Share on other sites More sharing options...
Av8ferg Posted January 24, 2020 Author Share #99 Posted January 24, 2020 Thanks for the previous advice guys. Made progress this week despite a few minor setbacks. I’ve installed the head, timing chain, timing chain cover and water pump. Here are pics from today. Sent from my iPhone using Tapatalk 1 Link to comment Share on other sites More sharing options...
heyitsrama Posted January 24, 2020 Share #100 Posted January 24, 2020 Looks great! is the block painted? Link to comment Share on other sites More sharing options...
Av8ferg Posted January 24, 2020 Author Share #101 Posted January 24, 2020 Yes, the block is painted. DE1651 Cast Coat Iron from Duplicolor. I didn’t really like the look of the Datsun turquoise blue, I thought it clashed with the red engine compartment. Blasphemy to some of the Datsun hardliners but it’s a 77, not a series 1 collector car. I really like the look of this block color. I have a red powder coated valve cover and I think the colors go well together. Sent from my iPhone using Tapatalk 4 Link to comment Share on other sites More sharing options...
SteveE Posted January 24, 2020 Share #102 Posted January 24, 2020 I agree! Looks good 1 Link to comment Share on other sites More sharing options...
Captain Obvious Posted January 25, 2020 Share #103 Posted January 25, 2020 Agreed Looks great! Now that you have the timing chain on, you can turn the motor over all the way. Did you spin it a couple times just to watch the valves open and close? Link to comment Share on other sites More sharing options...
240260280 Posted January 25, 2020 Share #104 Posted January 25, 2020 Basically a Mercedes Engine so their block colours are reasonable. 1 Link to comment Share on other sites More sharing options...
Av8ferg Posted February 1, 2020 Author Share #105 Posted February 1, 2020 Hey guys a couple questions. I’ve disassembled the thermostat housing assemblies for cleaning (probably going to put them it in a media agitator / tumbler because it has a lot of corrosion, oil and coolant residue. It was really hard to remove those sensors. So there are several sensors in this thing. 1. Thermotime switch2. Water temperature sensing switch 3. Thermal Transmitter4. Water Temp Sensor. 5. Thermal Vacuum ValveSeems like a lot of redundant sensors but I plan on replacing all of them. Actually will clean and test the Thermotime switch first because that one is pretty expensive. So there is another sensor that that goes on on a block just above the Thermostat housing. It has two wire coming out. Reading online it’s another Water temp switch and is used as part of the EFI?. I was reading the EFI bible and it seems to be written for a 280z not the ZX. I realize the concepts are the same but it seems these sensors and switch might be in slightly different locations because the pics in the Bible of the sensor housing are different than what came on my 82 L28. Can anyone clear this up. See my picsMy initial impression is that the TVV and the Water Temp Sensor were put in the wrong place. The TVV isn’t supposed to be on to the Thermostat housing but on the other component. Thoughts? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Captain Obvious Posted February 1, 2020 Share #106 Posted February 1, 2020 (edited) Took the pic out because I think they DID move the TVV into the thermostat housing. Edited February 1, 2020 by Captain Obvious Link to comment Share on other sites More sharing options...
Captain Obvious Posted February 1, 2020 Share #107 Posted February 1, 2020 At least that's the 280-ish version of things. They may have started mounting the TVV up in the thermostat housing for the ZX's. When I get a chance, I'll look through other pics. Unless a ZX guy can come in and answer first.

Av8ferg Posted February 1, 2020 Author Share #108 Posted February 1, 2020 Off the top of my head.....I think the big one is the Thermotime switch, not the one going into the block. You think there is enough temp sensors on this thing...OMG! Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
