I am still dealing with exhasut odor inside my vehcile at idle. I cant figure it out.

WHat would allow exhaust to come in the vehicle? I have even used expanding spray foam where my heater core comes thru the firewall. Still getting the odor.

would a slight header gasket leak cause it? How would it get inside the car anyway even if it did leak?

if it's only at idle, maybe your collector gaskets are blown out a bit??

 

I did have leaks there, but I just installed Dead Soft aluminum gaskets on the collectors. Still having the same issue.

Maybe my header gaskets are leaking worse than I thought?

I am running copper gaskets and they have been on the car for about 4 years.

might wanna check those gaskets, I just changed my headers gaskets about two weeks ago and the driver side already developed a small leak

 

WHats the best gasket to use? I get confused doing on a search on the subject.... everyone "Hates copper, loves copper, loves aluminum, loves falpro 1406's "..... AHHHHH

to be honest i don't think it will make all that much of a difference...just make sure ya clean up the header flanges and the ports on the heads...I'm using grade 8 locking bolts right now, but think i'm gonna try the ARP's next time...that 8mm head makes getting a box wrench on them childsplay....

 

i think you answered your own question of which gasket is best... you went 4 years without blowing header gasket, your lucky to get a year out of a set of paper gaskets.
