Heat exchanger/exhaust connection

[matt-me]

Have noticed a bit of leakage around this connection. Haven't had time to dismantle to see if it is a rusty pipe connection on the exchanger itself but on first look it seems to be a poor seal. From the manuals and parts catalogues it seems the exchanger pipe simply slides inside the exhaust pipe and this is then clamped. Am I correct?? and is the exhaust pipe split to allow it to tighten up??

Will this leakage affect the performance much? I have four into one but i don't think this affects the principle although it may not be split like the original, if that is on fact the case.

Any ideas to seal it if it is siimply a poor seal?

Thanks

Its exactly as you describe, the J tube inside the heat exchanger (the exhaust stub you see coming out of the heat exchanger) litterally sits inside of the header, then you have a ring and a donut and two u shaped clamp parts that bolt together to hold it. There is no split in the pipe to tighten one pipe down onto the other.

On first inspection when fitting, the clamp doesn't actually seem to hold the heat exchanger side at all. The trick is to generously apply exhaust paste to either side of the donut seal, and upon clamping it will provide a good seal once warmed up.

Its usually best to get a new fitting kit, as old parts tend to break when removed.

Performance shouldn't be greatly affected by a small leak, but you could get a back fire in some conditions.

Hope this helps

Thanks Gareth. Have been experiencing the backfire as suggested. I wanted to know this could bsimply be the problem in case i needed to buy some parts before i dismantled. Seems to be the case
