Going to Interstate to pick up a new battery today. Am I a victim of all the drugs I did in college or are the poles reversed on the battery to keep the positive pole away from the metal fender? Did I dream it or does the Z take a reversed pole battery? Thanks, Eric

I'm rebuilding my brake master cylinder - Tokiko off a '71. I have all the fittings removed as well as the set screws. My manual doesn't say how to get the pistons out. There's no place to get a grip on it. The only exposed end is a concave cup. Anyone have any suggestions? Should I try to use air like you do for caliper pistons? Thanks, Rick

My heat is broken on my 78 280z. I thought it was the valve on the outlet from the heater core at the water pump. I pulled the vacuum line and antifreeze poured out of the line. This doesn't seem right to me. Should I replace the valve? If not, does anyone have any thought as to what I should do next? what could be causing the vacuum line to be sucking up the coolant?

I've got a 1978 280z 2+2. Can anyone suggest a place for me to get a second set of keys? Do Nissan dealerships make duplicates of Datsun keys? I just want to have a second set for backup.

Valve Adjustment L28

I've got loud valve noise, and have set about adjusting them, but have run into a slight problem. This is a N42 head, and the intake is supposed to be .025 and exhaust .030 when set hot, .020 and .025 when cold. I'm setting hot. Was able to set cylinder 1 ok, but moving to cylinder 5, I can't get adequate clearance even with the adjuster as low as it can go. Do I wait for the engine to cool and then try or what? Thanks in advance for the help!

I stumbled across a car shop near my area that is selling a 280zx turbo engine with auto tranny? I already have a 5spd from a 78 z. The owner said it is running and is ready to go inside my z. He is selling it for 300 dollars... Could i take off my stock su's and place them onto that engine? or will I have to go triple mikunis? Since its an automatic. The owner will give me a plate from a 280zx tranny to fit my z. I was wondering on your inputs and suggestions? Thanks Andy:knockedou
