Blocking heat from exhaust manifold to engine

jimmythenose · Aug 22, 2009

Hi All,
Thanks to your advice my landy is almost running like a dream!! I have one last problem... whilst driving the heat from the exhaust is heating up the carb above causing a less than smooth drive!!! Any ideas as to how I can block the heat from getting between the two???
Thanks
Jim :doh:

I bet they invent some sort of Heatshield material soon just for this purpose

the other option would be to make a heat shield out of metal but it would be less effective, the exhaust wrap isn't cheap but its used in everything from kitcars to race cars and contains stuff like kevlar and ceramic

edit:i cocked up there that one is stainless steel and ceramic thread rather than kevlar

Heared nothing but good reports about ceramic coating the internals of the exhaust. not as expensive as you think neither but its not as cheap as the wrap thats for sure. Might even get some more Bhp especially if you do the piston tops also

There should be an insulating block uder the base of the carb, expressly for the purpose you mention, also some spec had a fibrous heatshield assy.
I would not think that you need to wrap the exhaust on a 2.5 petrol, as this was never required on any of the four cylinder engines , even in tropical conditions . You need to be looking if you are getting a air leak on the carb when hot . or vapourisation due to heating of the lift pump . HTSH
