just when i think i'm done with all the car expenses...

It's probably easier to get dry ice so might do that, just a buck of water with dry ice and then go around looking for leaks but my guess is i'm going have a lot. When I wash my car I get so much water coming in from everywhere...

I think I'm going to have to order a full weatherstrip kit

Yeah it started happening after i closed the air intake chimney. There was nothing attached but I'm guessing there must have been something attached. But my mechanic removed the old fan/heater and installed an AC system and I'm guessing he left it open. If I unseal the vent things would go back to how they were, air coming in from the outside and no exhaust fume smell. Problem is its like 120+ degrees here right now so having hot air coming in through that vent isn't an option.

Ah that's interesting information, thanks

I think I'm gonna try that, make the tip stick out beyond the bumper although looking at a side shot of my car it seems the tips already are passed my bumper. Need to go down to my car and take closer look

can someone help me understand where the exhaust could be coming in from? For example could it be a hole in my exhaust pipe or is it coming in from the rear of my car? The reason I'm asking is that it's coming in as I'm driving, shouldn't the wind be sending the fumes away and behind my car as I drive instead of inside the cabin?

Hey guys, I recently had an AC system installed in my 240z, it's a second generation 280z AC unit and I had an issue with it since I kept feeling hot air coming into the car at high speeds. So after a bit of checking I noticed two leaks from the firewall which i sealed off and one more larger hole on the passenger side, under the dash that brings in air from outside (picture attached). I ended up sealing that large hole as well with insulation foam and it solved my hot air coming in issue BUT, now I have another issue. I can now smell exhaust fumes in my car. My theory is when I sealed that large hole the air pressure in the car changed and it is now sucking or letting air in. Does that make sense?
