Fatboy Posted December 30, 2012 Share Posted December 30, 2012 Evening all!, I'm Megasquirting a V8 so it's going to have a Lambda sensor in the exhaust.. I'm fitting tubular manifolds and have seen posts suggesting that sealant is a good alternative to the tin or fibre gaskets. I've also seen posts advising that lambda sensors don't like silicon. I've bought a tube of Hylomar EAP5 which says its good for assembly and has a picture of a flange assembly on the front.... I've also got Tiger Seal but can't find a temp rating.... Has anybody got any thoughts or opinions, or suggest a more suitable alternative? Thanks, Donald Quote Link to comment Share on other sites More sharing options...
elbekko Posted December 30, 2012 Share Posted December 30, 2012 What's wrong with the standard gaskets? I wouldn't use silicone sealant on an exhaust, I don't think that'll last. Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted December 30, 2012 Share Posted December 30, 2012 Just bare gaskets on the exhaust ports.. They get a tad hot.... Further down the exhaust use exhaust paste. Don't use silicon in any part of the engine air intake system. It will cause issues with your lambda sensor. There are lots of good silicon free gasket alternatives for plenum etc. Neil Quote Link to comment Share on other sites More sharing options...
mmgemini Posted December 31, 2012 Share Posted December 31, 2012 I've not ever used any sealants on the exhaust Quote Link to comment Share on other sites More sharing options...
Fatboy Posted December 31, 2012 Author Share Posted December 31, 2012 Thanks for the thoughts, standard fibre gaskets it is then! Happy New Year (in 14hrs!) Donald Quote Link to comment Share on other sites More sharing options...
