Tim_H Posted March 13, 2005 Share Posted March 13, 2005 I've just replaced my rear exit exhaust with a 4-2-1, side exit. I managed to leave the primaries in place, and just change the collector, and silencer. I've now developed a blow at the manifold. Question is., I appreciate that I need to re-gasket, but is there a trick to lining all the exhaust up before connectijng it all up? btw, i'm on the bottom (lower) hole of the bracket by the passenger seat. - is this the one you used? thanks Tim Link to comment Share on other sites More sharing options...
Burt1969 Posted March 14, 2005 Share Posted March 14, 2005 Yep I used the lower one. I recently replaced my rear exit with a competion exhaust and still having problems with the gasket on the middle two primaries. I think at some pint I will take it to a machine shop and see if they can level the bracket off. Our Kitty! Link to comment Share on other sites More sharing options...
Midnight Posted March 14, 2005 Share Posted March 14, 2005 Tim are you K series, Vauxhall or Xflow?. if its a Xflow then the centre manifold joint is usually suspect due to the fact that you have just two bolts holding the exhaust to the head with nothing to keep the centre of the gasket tight against the head. so this is where they usually let go. There are special thicker gaskets available. see ad in low flying. or for a permanent fix you can get a thicker flange for the centre siamesed pipes that does not bow like the standard flange when it gets hot.

Terry Field Posted March 14, 2005 Share Posted March 14, 2005 You need to get a set of copper manifold gaskets from Chris Wheeler at the 7 workshop (www.7workshop.com). It is worth checking that the flangefaces and block face are undamaged and smooth, but the copper gaskets should do the job Terry Q783 OOR. Team Lotus colours with flares.
