So I replaced the headers and pre-cats on my '01 XJ about 1 year back... and have had a very slight (now much bigger) leak where the end of the pre-cats meet the crossover pipe under the transmission. There is a flat flange gasket that has 3 bolt holes... and apparently the connection point isn't flat where the pre-cat pipe meets the OE crossover pipe. So my gasket is leaking there.
I'm in need of some suggestions. Are there any thick gaskets for this connection point? Can I double/triple gaskets or will that cause a leak? Any suggestions or help is appreciated as this area where the exhaust leaks is REALLY loud and annoying since it's right under the drivers seat and I'm also pretty sure it's allowing a LOT of heat to be pointed right at my transmission were the exhaust leak is.
It might come down to me loosening up the 2 connectors where the pre-cat's connect to the header and then snugging the collector and crossover pipe before re-tightening the pre-cat to header connection. I'd hate to have to go that route as it's quite hard to get to those 4 collector bolts to loosen/tighten... if you can picture that area.
I appreciate any tips or ideas that I could try.
