Hi all, Following advice I read elsewhere (common Z problems), I checked my vacuum advance. It's frozen up. (You would think I would have found that out when I checked the timing with my timing light, but my light only worked long enough for me to confirm it was 10 deg BTDC, and not long enough to goose the engine. I guess that's something else I have to fix/replace. :disappoin) The breaker plate does move a little bit, but not as much or as freely as it should -- not by a long shot. I also checked the play in the distributor shaft. I get a wobble of approx. 0.010" from side to side. Is that OK? It's not TIGHT, but I wouldn't think that little wobble would create…

Hi all, My mostly uncorrupted '78 Z has a factory A/C. The high idle dashpot does actuate when the compressor clicks in, and it will hold a high idle when I let off of the throttle. However, if the engine is idling, and THEN the compressor clicks in, the dashpot is not quite strong enough to increment the idle. I've already disassembled, cleaned, lubed, adjusted, and reassembled the throttle linkages, and they're working very freely. Any thoughts as to how I can solve the problem with the dashpot? It's not a hugely big deal, but I'd still like it to work right.

Hi! My dad and I have been putting a ton of work into this engine and transmission, and it's finally ready! Except that I have to wait for my transmission mount I ordered and it's taking forever! But if I've waited this long I can wait a little longer I guess So I just wanted to know what you guys thought of it. Any pointers on putting it in? I have a cherry picker that I'm planning on using to drop it in. I'm also going to take off the carbs and valve cover so I don't risk hitting them. I'm going to put in an electronic fuel pump instead of the mechanical one so that's why there is a homemade plate where the old fuel pump should go. I'm going to put it back nea…

Hey I've got a 72' 240z. I bought i about a month ago,and i'm currently fixing the engine. It has been siting in a garage for the past two years, and was running before it was put into the garage. Just from sitting, the engine has seized up. Are there easy ways to fix it or should i just take off the head and do some more major work. Any help would be great. -chris

I checked the ignition timing on my car yesterday (finally) and the mark (marks) are off the end of the timing indicatior. BTW- which mark to use; the one on the pulley or the balancer? Maybe one was filed in by a PO? Anyway, the engine runs, but I had the distributor turned all the way to get the timing mark to about 20 degrees (at 800 rpm, without any vacuum advance.) If it was a V8 engine, I'd say the dizzy was installed with the drive gear a tooth off, but the L28 dizzy only goes in one way or the other (180 degrees different.) I think a visit to the Nissan dealer to have the S30 guy look at the dizzy will be worthwhile. Maybe have him rebuild it? Just getting …

I got an electronic ignition and coil from Summit Racing. From what I understand they are basically Mallory bits re-branded for Summit. So, it should install exactly the same as a Mallory Hyfire 6. After sitting on the parts for a bit, I decided to take it to an expert since I have very little confidence when it comes to wiring. The guy that I took it to came very highly recommended, but he deals mostly with the carbureted Zs. He said he has spark, but is having trouble getting the fuel injection to fire. I had a tach adapter with it, which is also installed. Does anyone have any experience with wiring an aftermarket ignition with a fuel injected Z? Any help would…

OK I'm about to go take a closer look and find out where the noise is coming from but what I know so far is it only comes on after I put the key in the ignition and power is sent to the car. The hissing sounds like air or gas or something is being leaked out or pushed out as it is fairly audible. It's coming from somewhere close tot the center of the engine. Anyway I'm going to go have a look at it with a flash light so I can actually see where it's coming from. The car is idling hard and almost always dies after being left to it's self for more than 20 seconds if that. It gets down to about a .5 rpm and just struggles and then shuts down. But does anyone know what this m…

I have a 1975 280z project that I've been working on and there so many things that I need to do. But I guess I should prioritize things and do them in the sequence of most urgent. My radiator is leaking and I am considering upgrading to an Aluminum radiator. My question is, should I go this route or stick with the OEM style radiators? Also where should I consider buying an Aluminum radiator from? I can't seem too many vendors out there selling the aluminum radiator for a decent price. Thanks in advance.

Hey Guys, My heater core blew and, as a temporary fix, I decided to bypass it entirely. It was an easy fix, just some new hose and clamps. After it was done, however, I took it for a spin to test it out and now the temp gauge doesn't work. I have no idea how the bypass could have caused this. I'm kind of grasping at straws but the only thing I could think of is either I got air in the cooling system and it messed with the sensor, or the rad full of coolant that emptied into my passenger side footwell shorted something. Any ideas? A little back story - I bought my 73 240 last year. It was in decent shape, definitely neglected for years but entirely complete and solid. Sin…

Has anyone checked out this Earl's pro-lite 350 stuff for use in place of the stock cloth tubing? From some of the pics, the braid looks similar to the original. In a bit of a bind here with half of my hoses braided (40 years old) and half not. It looks off. They need to be one or the other. http://www.earls.co.uk/earls/hose/prolite.html

Hi all, I have a transmission I pulled from a customers 72 240z that I have not seen before. Can anyone identify the one on the right? (The overhauled one on the left is going back in the car). Is it from a truck? Roadster? Thanks in advance. Anthony Q A&C Imports
