Hello all So I've owned my Z for about three months now. In complete love with it but I'm having a bit of an issue with it. When I try to put the car into second gear I *sometimes* get a weird buzzing sound. Sounds really like something spinning or something. I also get this noise sometimes when I revv the engine with the clutch in all the way and the car in any gear (but 1st and 2nd as I'm slowing down). I've been told it could be the throw out bearing but a friend of mine that owns a Z. Not sure if the bad tranny mount has anything to do with it. Any advise is appreciated. Jan. P.S Forgot to mention what occurred on thursday. I usually don't do this but I happen to hol…

I am about to install a new thermostat housing in my '76 280z. I thought it would be a good idea to check here and see if there is anything else I should be doing while I'm at it. I am going to replace the current thermostat with a 180 degree thermostat from thezstore.com. So I guess Im just curious to know if there is any thing to be done in addition with this small project? Thanks everyone! John

I notice when I pull out of 5th gear I tend to grind a little because I slightly tap reverse before I get into the neutral position and have realized this is because the shift lever won't return to center when I pull out of 5th and let go of it. It doesn't return to center from other gears either. Looking at the Haynes manual there is a return spring plug and return spring to the left and forward of the shift lever looking down through the shift lever hole from the driver's seat with the shift boots removed. I can see that the return plug itself is actually there. I remember reading another thread that indicates there are at least two different 5 speed transmissions th…

Okay I was starting to warm up the engine today to get a baseline readings on my original set of SU' before I remove the intake and install my new Ztherapy carbs. However, their was a prolonged screaming that was audible above the engine. I got out my 3 foot screwdriver and listened to every thing that rotates. Sure enough it was the tensioner for the AC right in front of the valve cover (you can see it in between the front of the valve cover and fan, sorry for the old picture). I removed the belt and the noise stopped. When I spin it, its very rough sounding as I think its bearing has given up the ghost so to speak. Now as we all know the AC units on our cars were …

How can I tell if my car has factory A/C or some aftermarket system? Car is a 1970 Z. Looks like a York compressor, positioned lower left under the distributor. There is a small dial for the A/C attached to the bottom of the dash to the right of the steering column. Does not work at present. Thanks, Mike

Can I use an E48 balance tube on an E88 intake? If so, is it a direct bolt on or does it need an adapter.

Gentlemen I am a recent member to the club and have purchased a 72 240 with a engine rebuilt (L28) by "Sumo Engine Co. (Canada 1992) Ltd They were located in Vancouver BC I have the warranty and service papers but nothing more than that. The work was done in 1995. The felllow I purchased it from said it had a performance can in it (very apparent) Anyone heard of this company?? - I know little about performance builders for Z cars and would appreciate any info out there. Personally - the motor seems a little over the top for a street car (as I wish to use it for) and I am considering bringing it back to a stock L28 any info or comment that would help? regards Dave

Hi all, I've FINALLY launched into troubleshooting my emissions equipment. Everything in the EGR system checks OK, except for one item I'm not sure about -- the thermal vacuum valve. It's the device with engine coolant running through it that supplies vacuum to the EGR system after the engine warms up. In the EGR INSPECTION section of my FSM (p. EC-13), it says: *Disconnect one end (BPT valve side) of vacuum hose connecting thermal vacuum valve to BPT valve. *increase engine speed from idling to 3000 - 3500 RPM *Make sure that thermal vacuum valve is close and that throttle chamber vacuum does not exist at end of vacuum hose. If a vacuum is present, replace thermal vac…

I've been trying to find a Crankshaft Pulley for this 280ZX (NT) I'm rebuilding. So far, haven't been able to find anything reasonably priced. Anyone know a place that might have one? (or if someone has a spare?)

I am thinking of changing my tranny from an automatic to a manual. Does anyone have a set of instructions or some special advice that I can read?
