While I was swapping a bell housings off a transmission (Datsun720(1981-83 720 Truck) to 280ZX type, I happend to lose a metal sim at front counter bearing. It is located at front cover. I called Courtesy Nissan, they said that there are 4 different thickness, and are national back order(comes from Japan in 4 months!) Now my question is, do I really need it? Sim size could be different depending upon how far I press in the bearing into counter shaft..... A transmission shop I know told me to use gasket maker rather than thick original gasket to compensate the thickiness......... I am looking for metal sim OD 6.2mm ID 5.4mm. (240Z-280Z ones are smaller in diameter) New …

Ok.. My car is stuck since 3 weeks because I cannot find the right gasket for my E88 head and I need a special gasket since I have flat top pistons.. I have a 72 240Z I'm in Mtl, someone told me that a 280ZX Turbo may be working... Can someone can confirm that?

Hey gang, this is my first post in this forum, (long time member of the other Zcar site). My car is a '73 240Z, mostly original, overhauled suspension, pertronix ignition, 3-screw SU's, nothing exotic. Anyway, doesn't seem I can do any major project without one good "learning experience" involved. This winter I did the timing chain set, water pump, intake gasket, clean polish, paint etc. Was considering the on-head valve seal job, using compressed air to hold up the valve. I was playing around with adapters to get the air into the cylinder, and it turned over, and and stopped with a thunk. Unfortunately, I had the timing chain off, so that thunk was the #3 piston hitting …

Here's a newb question for everyone. I am running a Crane mild street cam in my L24. I found my cam card yesterday and the valve lash specs that are on the card are not the same as the factory hot settings. Which specs are the correct ones to use?

Good 4 speed tranny in a 1970 Z (4095), ran without oil. After 40 miles, she seized. Can it be rebuilt or is it history. Before the 'incident', it shifted smoothly, synchros were strong, all was well. Any thoughts? Mike

I have VIN 8215 which has A/C. The A/C compressor is on the driver's side of the engine in the front (of course, so a belt can reach it) mounted down low (under the carb and exhaust). On another 1970 engine I just picked up, which as I was told was from a car in the 300s, there is no A/C compressor. Though in it's place is another item that has a hose which connects to the piece just above and connected to the exhaust manifold (the long tube that runs the length of the head and has smaller tubes connecting it to each port of the exhaust manifold)...I'm thinking maybe a smog pump. ??? I didn't think that the Z got a smog pump until '73 though. Anyone know what this is…

I know we have discussed determining what car an engine came from and how it is impossible based upon many many factors. I'm just wondering if anyone can tell me ROUGHLY where this engine may have come from? The number on it is 2776. Story is that the guy sold the car it came out of a 2-3 years ago, the person who bought the car was supposed to come back and get the engine and tranny yet never did. Fast forward to last weekend, I went and bought it from the guy who was tired of tripping over it in his garage. He told me that the VIN on the car it came from (the one he sold 2-3 years ago) was in the 300s. Not that it matters, I'm just curious.

Is it possible to use the input shaft from an early 4 speed to replace the input shaft on a '82/83 5 speed? The 5 speed input shat is scored where the seal sets. I would like to rebuild the 5 speed so it can be reinstalled in place of the 4 speed, which has a bad 3rd gear synchro and bearings a getting a little loud also.

Has anyone here run XADO oil in their Z? A buddy of mine just got some and after doing some reading I'm not too sure what I think about it. I'd just go ahead and give it a try, but its pretty expensive and I am kinda weary of putting in something like this. Apparently it will help reduce engine noise and other internal problems. I've come to realize that if there is an opinion I can trust about things like this, I can find it here. Let me know what you think. http://www.xado-us.com http://www.atomicoil.com/

I am about to swap from my stock cam to a performance cam and I have a question. In order to pull the cam, I need to move the fuel rail out of the way as it wraps around the head and blocks the cam from sliding out the front of the towers. Since the injector hoses are so short and they are clamped on, I don't see an easy way to get the rail out of the way without disturbing the injectors. Anybody have a trick that will save me time?

Hi guys, Finally got my carbs balanced (72 240 with SU's) but I can't seem to get a smooth idle. Trying for 750-800 rpm and get a rough labored idle, runs perfectly at 950-1000. Have fire to all the plugs, timing doesn't seem to affect it (as in cure the rough idle part). So, any recommendations on what to do? The intake water passages have been bypassed on this (wasn't me), would this cause my condition? I plan on hooking all that back up soon. Thanks, Justin
