Exhaust smell

[gtxdude]

I get exhaust smell in car with the top up (64 Valiant) trying to track it down. I don't believe there are flange gaskets were the exhaust manifold bolts to pipes. I'm running 1964 exhaust manifolds off of 273 does anyone know what size exhaust flanges I would need? 2 1/4 of 2 1/2 maybe? Better yet do you have a part number that I could use?

Do you have tail pipes?

 

[gtxdude]

Yes, full exhaust all the way back

It could be a bad rubber trunk seal. You can see how the exhaust follows up the rear trunk lid when it is cool outside.

I'll have to take a closer look at the trunk seal, very possible that could be it.

Could be coming in the top, too. I remember a friend, now gone, had about a 59-60 Buick 'vert. You could NOT run around with the windows up, that thing would gas ya right in the back/ rear sides? of the leaky ragtop

I will lay oddssss on the trunk seal,now this goes way back to the worst body job ever thread for me,why well when the body man installed my trunk lid back on he did not have it adjusted right now with the stripe I am stuck.I had exhaust coming in the trunk via the seal.I went inside the trunk shut the lid down and lots of sunlight in the 2 lower back corners.Until ,and i don't want to but maybe install some thicker foam along those areas,for now I shove rags in to help real bummer:wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack::wack:
