I've posted a few times here and haven't really said thanks for all the help- I really appreciate it. Hopefull soon I'll get more involved but at the moment my 73 is still in pretty embarrasing shape. Well here's my question: The spark plugs in my 1,2, and 3 cylinders are black and in 4, 5, and 6 they're almost new looking. Since replacing the plugs I've only driven the car approx 50 miles so almost new looking plugs isn't surprising but given the different conditions I assume the carbs aren't tuned correctly. Would the black plugs indicate a rich condition? I've gone through the basics on the carbs. Cleaned them, set the mixture nuts to 2 1/2 turns, and balanced them by…

I followed the FSM for installing the distributor/oil pump shaft and it matches the position and picture in the manual. when i put the distributor in and put the rotor on it seems to be in between two spark plug wires. the engine is set at TDC and i just want to make sure that this is where the rotor is supposed to be pointed at TDC. also, should the #1 spark plug wire be the one on top of the rotor in this position or just below it? Thank you much.

The injectors I ordered from Ebay came today. They were shipped FAST, packaged with great care, vacuum packed and look just as it does in the photo. I havent gotten around to installing them yet but they look fantastic. Everything was included to swap them out, even solder for the connectors and an allen wrench for the holder screws. The only parts I dont like are the connectors, they are of the cheaper variety, I may order the quick release type from MSA. For the price, they appear to be the way to go, matched to 2% of each other and a computer printout included with the sale. Here is a link for anyone interested, $143.30 total with shipping (I had a 10% off Ebay coup…

Does it matter which way the connector part of the injector is facing? I cant remember for sure which way mine were all facing when I removed them 10 days ago. I made a mental note but it seems my photographic memory isnt what it used to be I could swear that 1-2-3 were facing towards the rear of the car, 4-5 the front and six towards the rear again. Honestly, I am not sure if it even matters. I tried to look at some photos and have seen them turned all one way and other photos where they are going in opposite directions. I carefully marked the wires while removing them and when I soldered new wires, I made sure that I didnt cross anything up. Any help is appreciated…

I know it's an engine bay fastener, but specifically what is it used to fasten? One of the fasteners in the photo was attached to the battery-starter cable. The other one was laying on the right frame rail. I'm thinkin' they are vacuum hose fasteners, but that's just a guess. Also, since these are broken, where can I buy some replacements? Thanks in advance.

Ok so here I go again. The tranny is out of a 10/71, It has bad play in the shifter. Before I put it in the car I am replacing the shims and bushings. But I don't know witch kit to buy. I looked all over the trans for a part # and cannot find one. The only letter/number I can find is an L-2 casted into the side of the trans. What type trans is this?

I'm replacing all the vacuum hoses in my '78Z. The FSM is very helpful for showing what components attach to the ends of all the the hoses, but I'm having a litttle trouble trying to figure out how to route the hoses in the engine compartment. Two of the vacuum hoses attach to the intake manifold and run aft then along the top of the firewall (with 3 plastic clips) over to the passenger side where they (and a third hose coming out of the firewall) then run forward to the magnetic valve assembly and vacuum tank. This last part of the run is where I'm not too sure of the routing. In the FSM there is a diagram that shows these 3 hoses running forward and attaching to the e…

I've searched far and wide for this answer- including the motorcycle forums- where the question has popped up a few times. What is the proper orientation to install a new copper crush washer during an oil change? The washer is shaped like a cup, flat on one side with a small flange on the other. Rather than guess- can anybody tell me for certain? It's not addressed in the Clymer's either. I've also noticed that the stock oil pan plug does not have any magnetic properties. Does anybody have a supplier of magnetic plugs they can recommend? Rather than start another thread- another question for you all- Should there be ANY oil at all showing at the bottom of the cup where t…

hey guys, i got an offer on a 90-'96 z32 vlsd's w/ axles. 408 gear. for around 500 shipped to CA. I was wondering if 1) This will even fit in my 73 240z 2) If the price is worth it 3) What i will need to make it work. I have been doing some reading, and haven't found a 90-96 z32 diff with a 408 gear ratio? Was wondering if this is correct or not. I have read the forums and couldn't find anything. Please do help.

Let me start by saying that if you are thinking of saving some money and going with the Summit Racing aluminum radiator, dont. I have already spent enough that I could have purchased the one from arizona z car, and I still dont have it done. If you want the details of what has been involved so far, send me a PM, but trust me when I say it is not worth it. The latest issue is that the water inlet neck is right next to the mass airflow meter. By removing the mounting plate, I can make enough room to get the hose on the inlet neck. In order to mount it back onto fenderwell, I will have to make some major modifications to the bracket. I would prefer not to destroy the m…
