Bill h , if you could send me a tracing of the right side for my 1986 Barth that would be great . thanks , Bob Tomko 952 turkey hill rd Wampum pa 16157

Bill I didn't mean to get you another round of this! If you send me the pattern I can forward it to the others, I know you've done this before.

Doesn't need to be fancy, trace it on a newspaper!

I've asked Bill to send me a tracing too - Once I get it, I'll attach it as a PDF for our files.

I don't have a P-32 Chassis so I never needed it... now I feel compelled to get it up on our site for the members to have too.

great idea! (who was that masked man? he jumped in, helped us all and vanished into cyberspace. our hero bill ny)

Bill, would it help if I also photographed the pattern on our 3 inch tile counter?

BTW, the pattern is about 16 1/4 X 33 1/2", laid flat.

A photo on the 3x3 grid would be enough for me. I could scale it from that.

I presently have the driver side heat shield out of my 1987 in order to better access the spark plugs and wires. Anyone want pictures?

You've Got Mail.

Here are a coupla pictures











I have a photo of the pattern laid out on my kitchen counter tiled with 3" square tiles (set with 1/8" spacers, but it does not come out well on Photobucket. Any supporting member can PM me with E mail address to have a decent jpg image sent.

I will still send Bill NY the poster board pattern this week so he can .pdf it. A .pdf image can be sent to a blueprint company and printed exactly in real size, if that is important to anyone.

In this application, close is probably good enough. I don't think GM did a lot of wind tunnel testing to get this absolutely at its best. Anything is better than what they had. Which was nothing.

Maybe a tracing on butcher paper would be handy for the site archives. Who knows, maybe several members are missing theirs. Maybe they don't know, even.

After cooking and replacing several starters and disassembling my coach I found out about these things,here, and found one attached to the drivers side of the front wheel well area; none on the curb side. Who knows, if I would have found this site a year earlier I might still be driving "the Blue Bus" oh well! .... c'est le Barth!

If heat is your enemy and you want a better solution than pieces of sheet metal (they are better than nothing) see this site:http://www.atpwrap.com/. They supplied the heat protection for our diesel pushers and they will make them for any application. For a 454 you will spend less than a couple of starters, fuel pumps and overheated intake air to your engine.

Nice site, Tom.

I see they picture an exhaust manifold wrapped in their product. Looks way nicer than the asbestos wrap.

I would love to do that, but Thorley's lifetime guarantee is void if they are wrapped.

As for starters, I suspect most problems are more heat soak than air flow. This is evidenced by the failure occurring after it sits hot for a while, rather than right after shut down.

Do they sell their insulation by the roll or square foot, or what? I would like to try it for starter and oil line shielding. All Chevy owners need to be paranoid about starter heat, and my left bank Thorley is a little too close to my fat -12 oil cooler lines for comfort.

I think the sheet metal we are talking about here is more useful for getting rid of air, particularly directing it over the right rear plug wire and exhaust manifold than actually protecting anything from heat like a heat shield does. With proper air flow, things work pretty well under there.

The purpose of the blanket is to keep the exhaust heat in the pipes and away from the engine and exterior components. I suspect they will sell their insulation in any configuration however you should not wrap starters and pumps because you do not want to seal in heat, but get it out as quickly as possible. A properly timed and coolant supplied engine will rarely get above the temperature of the coolant. I can run my diesel generator for hours completely sealed and then wrap my hand around on any part (including the outer surface of the blanket) and the 200 degree fan actuation sensor will not come on. I think the soak problem is way over blown and I can't explain why Thorley won't honor a warranty. We have built stainless headers for our Cobras for ten years and recommended the wrap tape to keep the compartment cooler. We have never had a failure. It may have to do with the gauge of steel and the type they use. We use 16ga, not 18 and we TIG weld.
