more tvr 3000m blues-manifold advice

[stockpie]

Hi two weeks after picking up my six months at the garage 'bought as project' white/ brown 300M 1978 (and a hefty bill) took noisy car to an exhaust centre today and they reckoned exhaust ok but manifold knackered (drivers side) but no idea how to get such parts. Can anyone advise please where and approx cost. Can they be removed and re - gasketed so to speak the exhaust place thought unlikely ? Project inc cost is already pushing £6.5 k & have the pleasure of driving for about 15 miles in total !!
(On the bright side the bodyshell has polished up a treat twenty yrs after last clean and know spider crazing anywhere will load up before& after a pic when i work out how

Whats a 'noisy car' ? The appreciation of noise is different to all.......

They 'reckoned' the manifold is buggered ? So they don't know for sure ? top work....

The manifolds (pluriel) and gaskets are available from Exactly TVR, Coventry (400ish IIRC)

Depends what the problem is. If it's blowing from the gasket joints then it's pretty easy (assuming the bolts come out) to clean up and replace the gaskets.

If the manifold is cracked then you need to find someone that can sort that or you need to replace it.

Stainless manifolds are available from usual suspects or direct from ACT/JP Exhausts. ACT Link

Sounds like a bargain that's our overspend on the Taimar LOL

Thanks Gadge for helpful comments i think that was what the guy at the exhaust centre was trying to establish & its definitely drivers side noise he said so its gone straight back to original garage who did mention changing gaskets if the manifold did not break coming off- hence my request for sources and maybe be prices

Btw have driven 2 of these motors before settling on the project and have an mgbgt where the manifold leaked/ split last year so think I can I can differentiate between a V6 roar and exhaust related problems. The chap at the exhaust local centre was just doing his job not seen such an aged car for some time & not all places are as enthusiastic or knowledgeable about old cars as some people on this site are !

...and safe in the knowledge that overspend is relative given above post ! I feel better for the friday pints about to consume down the pub (walking of course) now. Cheers chaps

Where are you based stockpie,
I have some manifolds that are doing nothing if you want to collect?

Boroughbridge in North Yorkshire.

Thanks TVRMs have had a couple of offers today re manifold parts what a nice bunch the TVR forumsters are.....I will see how garage get on Mon & Tues and then get back to you, another kind TVR owner has e mailed me re manifolds too. I live in Nottingham btw

Hi guys and thanks for the offer of advice/ manifolds...which garage i use has told me now isn't the problem (of noise especially). having taken drivers side manifold off and reseated it today..instead seemingly its where exhaust & manifold meet they will have another go at it tmrw...i was happy to have a new exhaust put on but conventional tyre / exhaust place took too initially to make up and fit me a stainless job hvg phoned them and discussed earlier said that wasn't the problem either..... so declined my offer of a potential sale to be fair

Very confusing.... with my limited mechanical ability so any more advice would be welcome. The exhaust does look well worn inc a couple of bandages on it. Its a TVR 3000M, year 1978

[GadgeS3C]

Manifold to exhaust is just a standard exhaust sleeve join which any exhaust place shouldn't have any problem with - so seems a bit odd as it doesn't sound like a "TVR" problem, just a normal exhaust problem.

I'm puzzled.

Happy to pop over a have a look at it if only to compare notes with our system or discuss local places to try. Drop me a PM

My previous post might have been perceived as negative, but this is exactly what I meant; No one sofar has been able to pinpoint the problem. All in all taking the manifolds and exhaust off isn't a giant job (providing a lift at hand, and manifold bolts willing to co-operate......), and will tell you what is wrong. You can then decide on what to change/renew

(for the record I've done just that in the last month, including new manifolds)


The thing about the sleeves puzzles me a bit too, please report on that one !

I'd ask the garage to have a very good look where the three pipes join into one?

I suspected one of mine of leaking, took it off and blanked off the three flanges them poured water in.... Niagara falls!!!!

OK, slight exaggeration, but it did show up two or three hairline cracks which were "fun" to weld up, because of the condition of the metal as it heated up with the welding another crack would appear

Thanks guys all comments are taken positively i can assure....that and the three pipes join suggestion certainly i will put to garage ... will let you know how i get on.

If its the 3 into 1,its usually in the side facing the engine (just for fun.....) and as Mike says difficult to rectify. Tho understandable, as new manifolds are hefty in price, think you'd better go for new ones (pref; stainless). As stated Adrian does em to exact fit ....
