What's the difference between them? Is the '72 head a lot better? I'm asking this because I have a 70/71 240z and a '72 cylinder head sitting in my garage. I might have the engine rebuilt and I'm wondering if I should put on the '72 head.

Hey Guys, Im getting ready to replace the differential insulator mount, to hopefully get rid of my rear end clunk, and was wondering what the leased painfull way to go about it is. Is there any way to replace it without dropping the whole diff and drive shaft? Any suggestions would be greatly appreciated. Thanks

I've just joined the forum and already have a question. I'm working on a 73 240z that was put in the inlaws garage since 1985 and hasn't run since. I did get the motor running after putting in a battery and hooking up a gas line to the pump from a gas can. I removed the flat top carbs last night to rebuild them. While they were off I decided to clean up the engine compartment. When cleaning off the line that supplies hot water to the rear carb I noticed it was plugged. I tried to pick out the crud that was inside and it was bright yellow and soft like paint. Eventually after picking at the mess I realized that there was some wood also in the line. So I screwed a sheet…

Hi all, I just got a 76 280Z that's been sitting awhile and the clutch goes right to the floor. I tried bleeding to no avail and then changed the slave cylinder again with no improvement. I am going to be changing the master tonight and hopefully that's it, but I'm wondering if I am missing something I should have checked before throwing the new parts at it. There aren't any leaks, and I topped of the fluid. Any Ideas? Thanks!

So I'm thinking ahead now that the weather is starting to change and my Z will likely be spending much of the next seveal months in the garage. It's a 78Z, 4 speed manual (original stock set up). This summer I bought a 5 speed (and the 3.90 diffy) from an 83ZX and plan on installing it in the next few months. And I thought that this would be an excellent time to go ahead and replace the clutch. I've read alot of stories on this and other forums about the importance of matching up the t/o bearing, fork, pressure plate and disc from either the original set up or from the donor car. Here's my questions: 1. When buying the new clutch, should I buy one for an 83ZX (since th…

Ok so I'm running a '76 280z and the engine is all factory. The only things I have done is I've replaced the distributor cap/rotors, spark plugs and wires. Im looking to do some engine work to beef this thing up..I guess I would just like to know where to start. Any help would be greatly appreciated. Thanks a lot. Peace, John

Hi all, So I'm looking at my rear axle again, figuring out how to tighten it up. (It gets a bit bucky and jiggly sometimes.) I had previously noted that my passenger side half-shaft had a lot of play in it, so I knew I had some work to do there. Today I jacked up one wheel, left the other on the ground, put the transmission in gear, and turned the lifted wheel back and forth to figure out where I had play. The outer U-joint on the passenger side is pretty well shot, as I can see it rocking and wobbling around. The rest of the half-shaft joints, both left and right, look OK. They might be worn, but they're not a major source of play. Unfortunately the wobbly U-join…

So the rust monster has claimed another part of my datsun 260Z. I have rebuilt the engine completly minus one crucial part, the oil pan is shot! I was wondering if anyone knew where to get a good new/used one for fairly cheap. Ive put a lot of money into the engine so Im kinda looking for a less expensive oil pan. Thanks!

Can anyone out there point me to a supplier of the R-180 Quaife? It's time to pony up for a second/backup. Motorsport Auto doesn't offer them any more. Do I have to go to the factory to get one? Thanks. PS See what I can afford when I don't crash the car!

Where can i find info on the pressure valve and how to adjust it properly, and the person who put this car together put the vacc/boost gauge feed to the intake and all it reads is vaccum and does not go over the 0 mark

I am the new owner of a 78 280z....ok..ok it's a 2+2, but I had to get back into a Zcar. It's not perfect but it's got a solid frame and rails - which is rare in Missouri. My problem is that the accelerator sticks. I am able to pull the pedal back and it's fine. I have lubed everything but I think it might be the spring at the end of the rod (i think it's actually called something else). I haven't picked up a book on it yet, but I thought I would check with the experts first.

Hello all This past monday I took my tank in to get fixed as it has a crack. Before doing any welding the place cleans the tank thoroughly to get all the crap out. (as one would figure gasoline + fire = boom). So I though cool I'll get the thing back Tuesday throw it back in my car and be done with it. Today around noon i get a phone call from the guy that works there saying that with the amount of crud and gunk in my tank, it will take him longer to get it cleaned then expected. I agreed and told him to let me know when it was done. When I was taking the thing off the tank did seem like it was pretty filthy inside but didn't think it was that bad. So two questions for yo…
