engine and drivetrain Heat shield in engine bay

[NYNick]

What is that stuff underneath the distributor on the firewall? It's kind of crumbly, has to be some kind of heat shield. It's not asbestos is it? It's gotta go, but what do I replace it with? I saw somebody put in some EZ Cool on the whole firewall, but I'm not sure how to proceed.

 

Thanks

Hey, Nick,

 

I believe the firewall insulation pad is still available from BMW, and possibly from others such as Walloth & Nesch.  And it wasn't crazy expensive when I replaced the pad on my '76 3 years ago: somewhere between $100 and $200.

 

I doubt there's any asbestos in it, but I still wouldn't eat it or smoke it!

 

Best regards,

 

Steve

Part No: 51487450110

 

Shows as back ordered some places, but should be available.

1975 and 1976 use a smaller foam part, since the RH side has the aluminum heat shield.  Part number is 51481836651.  It's also cheaper. ($26 vs. $96 a year ago).

I used that EZ Cool stuff after reading about it from billpaterson... I like it so far but the car is not assemble, billpaterson could probably provide more insight than I when it comes to durability.

 

I added the aluminum on top, after installation:

 

I still plan on doing the floor pan with it as well.

I am bringing up this topic because want to replace firewall insulation on 1976 with RH side aluminum heat shield as harold indicated. I really don't want to mess with aluminum heat shield if all possible. So here are my questions;

1. Does anyone have pictures of part No. 51481836651?  Did not find it on internet. This one really interested to see pictures.
2. Other part number is 51487450110 (current price $223) and I know it is not available at this time, but internet search reveals 2 variants of 51487450110. Is this correct?
3.

Here is a picture of 51481836651 installed.  It consists of just the brownish foam part to the right of the shiny aluminum shield material.  Again, this is unique to 75/76 because of that aforementioned aluminum heat shield.

I had some crumbling on my 73. Directly adjacent my exhaust manifold.  I found Thermo-tec aftermarket sticky-back high-heat-reflective  corrugated aluminum sheets and cut 2 pcs to cover the same original areas.  I cleaned the area aggressively and applied the heat shield.  One year later and it's still stuck and pretty.

There is a guy in Germany that make reproductions of these.

I'll have a look later for a link. I think I bookmarked it somewhere

yes, my car is 1976 and that is exactly what I was looking for. Thanks again!

Here is the repro firewall I mentioned.

Not sure I like that reproduction all that much.

 

 

.....and a little bird told me that there is a state-side reproduction that will be available in 2-3 weeks.  Full closed-cell urethane, Fire retardant, etc.  Much better than the original even.  I saw the first pre-production test pictures and was very impressed.

AceAndrews - coming out of ATL?

I’ve seen it in person and it’s very well done!
