bill_gj Posted April 21, 2010 Share Posted April 21, 2010 I've tried to find a mention in the forum but.......What's the right clamp for the joint between the turbo outlet elbow and the exhaust downpipe on a '91 Discovery 200Tdi? I can't get the joint to seal and the way the downpipe mates to the elbow just doesn't look right. In summary - the clamp doesn't impresss me and the joint is never going to seal properly - has someone else fitted the wrong bits? Quote Link to comment Share on other sites More sharing options...
ches Posted April 21, 2010 Share Posted April 21, 2010 is this the clamp? http://www.lrseries.com/shop/product/listing/9260/3681/3/NTC4881-EXHAUST-CLAMP.html?sort=za Quote Link to comment Share on other sites More sharing options...
Les Henson Posted April 22, 2010 Share Posted April 22, 2010 You should put a thin layer of Fire Gum inside the downpipe, and a small amount on the outside of the turbo outlet, then put them together and tighten the clamp. Les. Quote Link to comment Share on other sites More sharing options...
redneck Posted April 22, 2010 Share Posted April 22, 2010 If it's the clamp that ches posted, I had problems with it as well, ended up putting a regular exhaust clamp on with a bit of exhaust paste, and not had a problem since. Quote Link to comment Share on other sites More sharing options...

bill_gj Posted April 22, 2010 Author Share Posted April 22, 2010 Ches - yep, that was the original clamp, but it had seen much better days and was closing up before it could clamp up the pipe properly, so it was replaced by a much heavier 'U' type - the sort of thing that you would normally see on, say, the joint between a silencer and a tailpipe. Les - yep, did that, just like you say, but just couldn't get the elbow and the downpipe clamped well enough to stop leakage. Someone else has said that there are two downpipes with differing lengths. If that's right, then this must be the 'short' one which is possibly why it won't clamp up correctly. Having worked on quite a few vehicles over the years and this being the first LR, I have to say what a useless design it is - I can't see the point of the "double-skinning". To cap it all, the next joint along (downpipe to silencer) is two flanges with a spherical sealing face - just the job for the manifold to downpipe. Why couldn't they have used that design??
