So I ran seafoam treatment (1/3 in crank, 1/3 in gas tank, 1/3 through vacuum line) and afterwards car was difficult to start, but I was able to start it each time. After I would get it started it ran very strong after 2500 RPM, but sputtered below. I've since changed oil (as part of sea foam treatment), spark plugs, wires, rotor, distributor cap. I've also cleaned off contacts for the distributor and ignitor. The last few nights the car wouldn't start at all. Today when I went to start it I heard a POP (backfire?) and some smoke (very little) was coming out of the air cleaner box. I noticed one of the carbs was low on fluid so I topped it off with ATF. I may have damaged…

I recently got my 72 240Z and i replaced the old slave cylinder and cleaned the master. Even how hard i try to bleed it, it wont move a bit. Is the master cylinder pushrod too short or could plain air cause this? I've got another smaller Datsun but it never had problems in there

I have a 77 280z that is fuel injected. When the car starts (sometime it doesn't) it will idle up to around 1200, and run well until the throttle is advanced. As soon as that happens the rpm's bottom out and the car dies. Occasionally, the car will start, but will only idle at about 600 and then dies quickly. Here is what I have done so far: New fuel pump, good pressure. New EGR valve. New air regulator. Cannot find any vacuum leak. When the car runs, the exhaust feels fine and there is no visible damage to the exhaust system. Cannot find any obstruction in the air intake... I am running out of ideas, can anyone help? Thanks very much.

Valve Keeper

I have a 1978 Datsun 280z w/L28 motor. First heard a ticking sound then it starting running bad like one cylinder. Checked the little stuff, all looked fine. Pulled the Valve cover and found that a valve keeper had come off the first piston (closest to radiator) on top of the 2nd spring. How can this be replaced and is it likely that a valve may be bent? It does still start but runs very rough still....no longer starting in fear to damage more (like the piston).

Hello guys. So recently I'm having a problem with my 1976 280z. The weather here in Tucson has been in the low 60's in the morning and when I come to start my Z it doesn't idle correctly. What I mean is, all other cars I have ever owned would idle high (around 1500RMP) until the motor was warm and then would come down. My Z does not do this. I have looked in the FSM for information about it but am having a hard time locating anything about it. Do you guys have any ideas? is there a way to adjust this? In the mornings it idles around 800 and when it warms it increases to roughly 1000. I am cleaning all the connections tomorrow to see if this will help but input would be n…

The all stock 72 240z (automatic) was running rough. So I replaced the spark plugs, sparkplug wires, rotor, cap, points (2-sets), and point lead wires (really rough shape) and condensors. Set the timing, no problems. I actually had it running well for one day. Then I drove to Zfest in denver. 50 miles each way. As soon as be got there, it started acting up. Started running really rough, backfired once, barely held an idle at stoplights. Got it home, checked the timing and it is about 20' retarded. If I attempt to adjust within the scale, the Z dies. It will not turn within the scale. I have checked the gap on the points, replaced the rotor and cap again, check…

Hello guys Did a search on this but didn't find my exact problem. Yesterday afternoon I was replacing my alternator belt. While removing the carbon canister I happened to hit it against the fender wall and knocked off the little nipple that holds the vac line that goes to the distributor. I tried gluing it back on but it hasn't really worked. 1. Does anyone know where I can get just the top piece. In the manual its called the diaphram cover. 2. Someplace I've read that the Carbon Canister from a Geo could be used is this true? 3. The carbon canister I have seems very odd as there is a large tube coming from the bottom. Is this normal? Thanks all Jan P.S Please don't adv…
