I've got tranny fluid leaking from the area where the front of the driveshaft slides into the rear of the tranny. Anyone have a solution to this problem or know of any previous posts dealing with this? I assume it's probably a seal of some sort. Thanks Guy

I have just realized I don't have a hole for the fuel pump (boss is there) on my N47 head. I will pull the head and take out the cast aluminum, is there anything particular I need to do or look out for? Thanks, Leonard

Well i work with guy who is a certified machinist/car lover and he used to work with all these high temp materials. And he was tellin me about a throttle body and plenum spacer he made for Chevy big block with this crank and that differential and this shifter u kno everything muscle guys like to name. He said those spacers got him about 2 tenths off his quarter mile because the engine air was much cooler with these high temp seals....well blah blah i asked him what would he need to make me one for the 280....he said get me gasket and ill make you one for 15 bucks. I said you got it. i mean fifteen bucks thats it. He told me when gets it done and he'll bring it to me at wo…

Hey guys. This past weekend I installed a new timing chain kit on my Z. As I'm going to run the valves this weekend and have the valve cover off I would like to reassure myself I did it right. First off I used the #2 hole in the cam gear to set the chain. This was the way it was when I took the old one off. Is that OK to do. Timing at the moment is 12@1000 RPM (idle). Secondly I have two manuals that have two different torque readings on the cam gear. The FSM says 90-100 ft lbs while the Haynes manual says 40 ft lbs. Which one is right? I set it to 40 ft lbs as the 100 just didn't seem like the right number to me. Thank guys Jan

I believe my distributor is off a gear. I adjusted my timing and had to go all the way past the adjustment hole to get it timed right. There are two timing adjustments and they are both adjusted as far advanced as they can go. I removed the distributor and found that it has a key way and cannot skip a gear. Any ideas? Is there a gear below that may be off a gear? If so, Is it a problem? the Z runs great now that I adjusted it. If its a problem, How do I fix it? Help Please. Chris

This is going to be fun... I just got this rolled '94 Pathfinder as a donor to make my parts car a four-wheel drive 240Z. My parts car is a 1971 but let me assure you that I am not destroying a perfect 240Z. It is a RUST BUCKET. The Pathfinder has a 3.0L V6 with EFI and 106,000 miles on it. I read that it has the same engine as the 300ZX (non-turbo) but it is a less "sportier" version and more aimed for low-end torque due to the cam. Is this true? I am not going to pay attention to much detail on this project as it is going to be a beater 4x4 that I can have some fun in. If anyone else has done something like this I would love your advice/input. Any other comment…

Hi All: Hoping for a little advice here. My 1978 280Z runs fine but when driving it if I allow the RPMs to get too high the car starts to hesitate and almost feels like it is bucking. Even when parked if the RPMs are allowed to get about 2,500-3,000 it hesitates and the RPMs drop despite my foot still being on the gas and there is a clear hesitation. Here is what I have done so far: Fuel injector cleaner in the gas tank, new wires, rotor, distributor cap, and checked spark plugs. Anyone experience this before or have any suggestions? Thanks!

Does anyone by any chance have one of these? Its for a 75 280 & the part number is 14055-N4200. Its a water by-pass hose that goes from the thermostat housing and to a pipe and then to a water inlet right in front of the head. Its an L shape and has 2 different size ends. Its the one on the right facing the engine. Bryan

Ok, after getting the suspension redone (fabulous) I am noticing a thin bluish-white smoke coming from the exhaust when accelerating (friend was driving with me following). Also when decelerating there is a small backfire/fart sound. The tailpipe also looks oily/sooty. It runs/idles well. What's going on?

I have an oil leak that I have pinned down to the side seals on rear bearing cap (L24). The engine was recently professional rebuilt. I pulled the pan off a couple of weeks ago and pulled the side seals out. They slid right out they where slightly smaller than the new nissan parts I had. I used CRC brake cleaner and pipe cleaners to clean the oil out of the slots. Then inserted the new seals with RTV silicone sealant, then put the pan back with a new Felpro gasket and spot of slicone at each of the bearing cap/block joints Let it sit for day. Then put the oil in and took it for a drive and I discovered the leak was reduced I would guess by 70%. Just few drops on t…
