under the hood on the passenger side is a white plastic bottle (vacuum tank) check the screws on the clamps that hold the 2 nipples that connect to the vacuum lines. Mine were loose and had the exact symptoms you are describing. Good luck.

I recently did a full brake job on my 76 280Z and also put on those braided stainless steel brake lines from MSA. The brakes seem to work just fine but when the car is on an incline the brake light comes on and remains on for 5 or 10 miles then goes off. I've definately ruled out the switch on the emergency brake handle as being the cause. No leaks and the fluid in the reservoir is topped off. I see there is a brake light warning light switch with 4 brake lines running from it under the hood but Nissan doesn't carry them any longer. Is that switch interchangable with other year Z's.Any ideas on how to tell if that switch has gone bad and how to check a used switch I may have to get from a junkyard.Any comments would be greatly appreciated.

My heater valve was leaking under the dashboard and was dripping right on that connection on the passenger side up near the firewall. Replaced the bad connectors and the flashers work perfectly.

One thing I learned along the way is when you get the new drivers seat mech cover, make sure when tightening the 4 seat mounting bolts that your seat is pushed to the center or the car. That way when the seat is slid all the way back it won't rub on the seat belt lower cover and damage it.

I've replaced my map light a few times on my 76 Z and was wondering if any one knew a better way to fix it. The bulb is fine just seems like a bad design the way you push down to turn it on. Also any one have any experience in putting a bigger watt bulb in the dome light? Thanks

Thanks, I'll check that area out.One place I did find that was leaking was where the right hatchback hinge is bolted on the roof of the car there is some factory sealer painted around this joint. Well in the almost thirty years I've had this car it looks like the sealer developed small cracks,leaked through the plastic rivet hole for the overhead trim and drips on the carpet! I just never saw any water on the hatch rubber and this is where it was coming from!!! I'm new to this help from fellow Z owners but it has sure helped when I run out of places to look for leaks. Thanks.

My 76 280Z's carpet was getting soaked after a long rain.I got the quarter panel all new rubber from motorsport and water is still getting in somewhere. The only thing bad about it is you can spray it with a water hose all day and it won't leak! Only when it rains. Any ideas? Also did the new rubber on the doors, body and windows. :sick:
