    Pre cat hell !!!

    Hi all,

    Had a brain wave.. Thought I'd buy a regal precat replacement for my coupe.. So get my local garage to fit it but where the clamp meets the manifold n precat it just keeps blowing he has spent 5 hours trying to get it to stop and no joy.. Has anyone had this issue if so what did you do to resolve it?

    Thanks

    i have seen a few posts on this....
    are you using a gasket??
    if you are discard it and dont use one.
    if you are not just make sure the joints are clean and are aligned correctly

    Yeah took that off.. Poor bloke he tried everything it just won't sit as soon as he thought it was done he tried it and it was blowing.. I looked at the join on the original precat and the new 1 and the new 1 looks slightly thicker??

    Bedford.. Been there again and the conclusion is that the precat join which butts up against the manifold is too think that the clamp does joint properly..
