how do you stop the fumes from getting inside the cab
does anyone have a hint.

we turned the tailpipe out and sealed the pan ??? help

 

sometimes the taillight gaskets are the problem & or the ventlines for the gas tank. pull that back panel off of the taillights & check those out.


do it Munkystyle !

 

Most old z's you'll drive have pretty bad exhaust fume problems. These problems stem from: the tailight gaskets being shot as munkyjuce mentioned, holes in the firewall allowing exhaust fumes leaking from the headers to come in during operation, and the MAIN problem is the rear hatch seals being shot also. Due to Z aerodynamics, exhaust tends to tumble around in a pocket of "dead air" behind the z, seeping in through the bad gaskets. In the mean time, try leaving all your windows up with the vent on. This will create a positive pressure inside the car, helping to keep those fumes from leaking in as bad.-Taylor

 

I had horrible fumes in my 260z 2+2. I found that it was the exhaust tip not being welded on properly and because the car was in an accident before there were leaks everywhere. I had an idea and that was to turn the exhaust on an angle so that the fumes go out towards the side of the car. Also the fatter the tip the more fumes will hang around the back.
Good Luck!!!

Hey Thanks for the info I will change the tail lamps gaskets and seal the fire wall

The aerodynamics on a old Z are funny.I found that if I leave only one window open its a little fumey but both windows down isnt bad at all. I resealed my tailights recently and leaned my carbs a bit..made a heck of a difference!
