exhaust pipe fixing

[tonygoodall]

Hi Guys Maybe it's just my car, but I just cannot get a decent seal where the front pipe meets the manifold, I've tried twice with new gaskets but no go and resorting to "goo" is imminent. It seems to me that the detail is flawed; a gasket covers the base of the manifold which is then borne upon by a steel ring which then has to seal against the exhaust pipe. The sales brochures from the suppliers show this detail as being the same for TA and TC, but I don't remember my old TA as being like this, I'm sure a more direct bearing surface was employed and no steel ring. Anyway, is there a trick I'm missing here? or has the ring distorted? or does everybody else use "goo"? Regards Tony TC9825

There was a thread on this last winter. When I put on a new system last winter (yes, G. wheatley doesn't even know what the correct exhaust setup is on a TC - a very simple thing), I went to Midas Muffler with the head pipe and manifold. We went through their bin and found a modern donut gasket that fit pretty close to the 2 flanges. I eliminated the copper gasket then carefully and evenly tightened up the 3 nuts holding the head pipe flange. The result was a better seal at that joint than anything I've seen. An inexpensive and good solution. The donut, while harder than the ones you eat, is still "squishy" enough to compress to match the joint. While everyone loves to chrome the outside of everything, I instead polished the stainless steel exhaust to make it shiny and pretty. Looked great - then I studied the old pictures and specs and it seems that exhausts were painted black with the chassis. Think I could take some pictures and become an eccentric? I was even thinking of putting a TR3 heater in the TC for the winter.

Tony, Some exhaust systems that come as a kit do not have the correct angle if you fix the down pipe to the bellhousing with that tab. Fitting it forces the down pipe at an impossible angle to the manifold. It is minor, but enough to make it leak every time. If you get a good seal and then force the pipe over so you can fix it to the bell housing it will destroy the seal. I had to re-do the bellhousing tab after the seal was good.

This somewhat related, who makes the best exhaust header for a TC that will connect to a stock muffler or straight pipe? Bob TC4956

Bob: The "Derrington " Extractor header is the best. It is being produced and sold by Brown & Gammons in the UK. I have been running one on my car since 1961. Skip Kelsey...................................... At 08:20 PM 8/24/01 -0400, Want1937hd@aol.com wrote:

Bob, Skip, et al - the Derrington extractor is actually made by "Mike the Pipe" in Wallington, South of London (Tel: +44 20 8669 1719, Fax: +44 20 8773 4096), and obviously cheaper direct from him. Mike actually made the jig at Derringtons many years ago, when they were still in business in Kingston on Thames, and I can also vouch that it is a perfect fit! ocTagonally TCRoger

On my exhaust manifold to tail pipe the assemly sequence placed the triangular copper and fiber gasket against the maifold flange followed by the tapered metal cup into which the taperad exhaust pipe fitted. The flange on the ehhaust pipe is the bolted up to the exhaust manifold as tightly as possible. This detail allows the exhaust pipe to move around, I suppose without leaking. Hope this helps some.

Tony I had a similar problem some years ago, what I did was buy some muffler/silencer patch, (it is like a gasket sealer) and put it on the donut before you put it in place, it does work. Cheers Dean Illinois

Roger, Then you will probably remember old Bill Thompson in Wimbledon. His advert appears in early editions of "Blower". I remember always calling in at Vic Derrington's shop in Kingston on my way to Thompsons in the early/middle sixties. There was another MG firm just down two blocks and over the road from Thompsons (whose name escapes me). Rich pickings back then! Happy days! All the best, David Lodge, TC 1704 (same car!)
