time for new door and hatch seals. lots of fumes get sucked into a hatch that wont seal well.

Check shifter and e brake seals as well.

Got cats?

With the complaint about heat plus the exhaust fumes, I guarantee you the inner boot for the shifter is either missing or hugely torn.

i have no cats and how do i check for the boot i was thinking of washing the motor and trany firewall headers anywere were oil can touch realy hot things and smell i mean i cnt drive the car like this when i get out i smell like a mechanic

to check for the lower shift boot you can remove the plastic frame around the shifter by just pulling up on it, and then removing your shift knob and take off the upper shift boot. There should be a rubber boot and a metal frame on top of that. like this:

The lack of cats is why your car smells. The probable lack of the shifter boot is more than likely why you smell.

+1

That was part of the reason I put cats back on my Mustang. Even with good door, hatch, shifter seals...i still smelled like raw fuel from time to time. Got old quick.

the car smelled like this even before i took the cats off im thinking its prob going to be the boot seal plus i dnt mine the smell of gas or fumes i just dont want them in the cab i been in a couple of stangs before and yeah some of them do smell but its aceptable but this is realy bad

 

[wythors]

Do you have tail pipes or dumps?

 

[rudy herrera]

i have tail pipe the motor seams to have a little oil on it do you guys think i should have the motor presure washed the trany looks a bit dirty tooo the boot seal is in the seals seams to be a little torn but the smell does not seem to be coming from there do you thing i should replace it still or no

 

[ID89GT]

I would replace it.

 

[stykthyn]

Replace any worn seals before you start messing with anything else. Fwiw I don't buy the no cats issue. Cars ran for decades without cats and didn't reek of gas. My car runs without cats and it doesn't smell.

But fuel-injected 5.0's don't. They REEK. It's in the tune.

Do you have any exhaust leaks under the car ?

Since fumes are coming in, you prob do.
