As we all know 67-69 Camaros used putty? in the Rivits that retain the tag to the Firewall, but I have looked at a lot of Documented 1970,s lately and have noticed quite a few original cars with just the open Rivits.
My Question is this- Did 1970 and up not use the filler in the Cowl Tag Rivits?
What was the reasoning behind sealing 67-69 Cowl Tag Rivits? To stop water from the cowl entering the engine bay or vice versa?

good question, the 73 we have here has no putty!! never thought about that before...

I Know, nor have I until the other day.
I was looking at a Friends 25,000 mile documented 1970 Z28 Survivour and it has no putty. He also has a Documented with the Pontiac Historical Society -1970 Firebird 20,000 mile Ram Air 4 and it also has no putty.
Wonder if it is a 1970 up deal?

70-73 deal to be exact, somebody correct me if i'm wrong but sometime mid 73 they started with the screws. Bill will you provide the tt build date for that 73.

Is there a hood to firewall seal that would prevent engine gases from getting to the tag on 1970 and up cars? It is most likely where the tag is positioned compared to the first gens. The first gens were IN the engine compartment and all holes were sealed to keep engine gases out of the cabin.

When I did my firewall resto I didn't know any better and ended up wire brushing all the putty off...Oh well..

My 10C 69 Norwood car did not have any putty in the rivets at all. Maybe it shows up on late production cars, because I almost bought a 10D car,and it did not have the putty either. Seems too coincidental.

50's cars used similar 'rivits', and did not use putty in them....

I think the putty was there to keep engine heat/fumes from getting into the cowl, then inside the car through the cowl then the kick panels.

On a 2nd gen, the cowl tag is on top of the fireall, and outside of the hood-cowl seal effectively seperating it from the engine compartment and the cowl (hood) vents. Maybe they didnt see the need to seal the rivets?

I have no idea if that's why or not, just an idea.

Dave & Dave have it right - it is to prevent the engine fumes from going into the cowl / interior.

Haha... I completely missed the other Dave's post. Hell, I was just going on something I thought I had read before, and maybe a little bit of logic... throwing something to see if it would stick :D

I'm still about 5000 from the end but yeah it's cool. When I bought this in the mid eighties I wondered how far from being titled as a 70 I was.:D Thanks to the CRG and the internet we know now;)
