any ideas on how to keep the exhaust fumes out of my 72 squareback. im hoping its something as simple as the rear door seal. if it is, where can i get a good quality one?

my guess it is crappy seals of the exhaust on to the heater boxes

Any movement where #1 and 3 join the exhaust?
Can you feel air??

The take off for the heater is near there and it sucks the fumes in

A flange kit is the best answer

Yeah, most VWs tend to develop exhaust leaks. If you wrap a rag around your hand (or wear a glove) and block off the exhaust with your hand whilst the engine is idling, you should be able to hear it chuffing out of the leaks. You'll need to take your hand off every couple of seconds so it doesn't stall, and get your head right under there so you can hear where it's leaking from.

I'd say a flange kit is a bit extreme, but it's probably worth it. If you go through the exhaust system and replace all the gaskets and make sure all the clamps are clamping nice and tight then it shouldn't leak.

yES IT COULD BE THE REAR DOOR SEAL SUCKING IN THE FUMES....

tape up around the rear door with masking tape..

and then see if you can still smell them...

You could also try putting an extra piece of exhaust pipe so it goes past the rear bumper...

but a rear seal will do it.,...

I can't see how any leaks in the exhaust would get into the car....

taped up the rear door. problem solved! Looks like the cheap seals dont work.

try adjusting the latch so that the door latches a bit firmer.
