Hey, My z has lately been running rich. It smells okay but when I pull the plugs they have a decent amount of carbon buildup. I have gone through every component check in the EFI manual and can assure that all EFI components are working as they should. So I leaned out the car by tensioning the spring in the AFM, a lot. And it did get leaner but the plugs are still sooty. So I leaned it out more, and the car wants to die at idle. I then turned the AFM idle control screw clockwise to richen up the idle and it does nothing. It seems that the fix of my problems would be to just richen the idle but I can't seem to control that via the idle screw on the AFM. Any id…

I have my engine apart to replace the head gasket and timing cover gasket and I noticed today a small pin on the bench. I'm not positive it is from the engine but I have never seen it before. On the bench I have had the oil pump, head, timing cover, thermostat housing and the chain tensioner. It doesn't appear to have an oily film on it but It could have been cleaned while I have been cleaning parts and scraping gaskets. It has a black coating on it and has one small area that shows wear. Any thoughts?

Hi fellow Z enthusiasts, I’ll start off by listing my specs: 1973 240z L24 w/ Triple Webers *all smog pertinent items have been removed/blocked* I had SU’s that crapped out on me about 9-10 months ago so I decided to grab some triple webers as a nice upgrade. The car ran fine when first installed and tuned up. However, after that it sat for a about 4-5 months while I was in another state for work. Current problem: Once started, it does one of two things: 1. Revs high mid 2’s to 3’s 2. Idles fine On throttle Full quick throttle presses: 1. It has an absence where it doesn’t rev at all, almost like there’s a popping. 2. It drops a little Slow throttle presses: …

Hello everyone, My son and I purchased a 1976 Datsun 280z 2+2 for his first car last month and it will be our father/son project car. With that said, we have been trying very hard to get his car ready for Pennsylvania State inspection on the 8th of May 2019. We have been working hard and have been reading many of the z car forums, watching youtube videos, and reading as much material as we can find. Thanks to all the information out there we have successfully fixed numerous issues, but we still have a few things to go. My son has big dreams for this car but we are trying to make it road worthy right now as all the rubber is old and falling apart. …

I am having a difficult time in removing the rheostat that controls the dash lights in a '78 280Z. I have followed the instructions outlined in the FSM and can't get to it. There must be a better way. The PO had installed a dash cap and I had to remove it and tons of silicone just to remove the tach. Has anyone done this from beneath the dash? Randy

Hi guys, So I was driving today and somewhere in the rear I started to get a clicking/ratchet type sound when I was coasting out of gear. The sound speeds up and slows down in a 1:1 ratio with the car's speed. It is most evident when I'm going slower and seems to not click as loudly when I am in gear compared to coasting in neutral (but I could be wrong). The sound is not super loud but is very noticeable. I have attached an MP3 of the sound but if that doesn't work, you can hear it here: https://vocaroo.com/i/s0pvF7JKlewZ Any ideas? -chase EDIT: I got it up on stands and spun the rear tires. The clicking seems to be coming from …

Vents PCV Crankcase Valve Cover.pdfVents PCV Crankcase Valve Cover.pdfVents PCV Crankcase Valve Cover.pdfCurrently I have the crankcase vent tube disconnected, the valve cover vent has a small filter, and the PCV valve has a rubber cap secured with a clamp. After doing some reading on each, I realized that I should make some changes to ensure that gases are not building up under the hood, foreign material not going into the vents (either ccase or vcover) and that i should protect both from backfire pressures if I connect them to the airfilter and/or to the PCV valve. It seems that having the PCV valve connected to the Crankcase vent is beneficial beacause it has sl…

After last top off gas leak from hose #7 here: https://zcarsource.com/gas-diag. Currently this hose make a big loop down before heading back up, I'm questioning that is correct. I'm replacing the hose tonight and am wondering if it were installed wrong in the past, diagram looks like a fairly level shot. In our case filling up to the point the filler neck has gas in it must also fill this vent line, it started seeping out. I'm thinking of redoing with a more level hose. Wondering what is "correct". BTW, anyone know the ID of this hose?

Leaking water pump, possibly the original pump. Searched all the forums, Googled & YouTubed. Used pen oil, heat cycles, shocked the bolts, still 3 of 5 fasteners sheared during gentle removal including both M8 (one at the head and one at the threads) and the long skinny M6 (at the threads). sigh. Looks like to deal with extracting the sheared bolts, need to remove the timing chain cover. Sounds like draining the oil, removing the oil pump. Then can remove the distributor then the timing chain cover. Timing (points ignition) is good right now, want to remove the distributor w/o screwing up the timing. What's the pro method for setting up the engine before remo…

Need some help on what to do next, here's the story so far. 1976 280z California edition (manf. date Sept.1975). Bought the car in late Jan. 2019, car passed emissions test and it started and drove fine until 2 weeks ago when problem first occurred.

Try to start again and engine cranks but will not start. Let it sit for …
