Inlet manifold adaptor?

[Adrian]

Before I crumple into a gibbering wreck I got a contact number for Ian from Angie at HQ.  I believe he is quite difficult to get hold of.  Has anyone had any contact with him recently - I can't see any reason why the details should be wrong as his wife is a member but it just rings out, no answerphone or anything !

Old engineers are quite often technophobs, you may have to send a carrier pidgeon.

Hi Chaps

 

I am most definitely out of my depth here with both confidence and skill - I hit rocks with hammers not manifolds, my 'O' Level metal work 35 years ago didn't cover this! I have to find someone to do it for me - if I fail to get Ian on the job are there are any willing volunteers? I can bring the biscuits!

 

I've had a bit of a dig around - non-destructive of course. I can see a coarse thread standing slightly proud of the manifold at the sheared banjo end - is this the banjo bolt thread or is there a sleeve? It may be clear if I had a replacement but haven't got one yet.

 

Secondly does anyone have a spec / part number for the inlet hose connector - it seems the mk1 and 2 had a sensible nut included in it. Pt 138810 at canleys. But there doesn't seem to be any info in the usual places for the mk3.

 

I got a leaflet from a local restoration garage who said they'd have a look - but I don't think you can beat the confidence you get from a recommended engineer.

 

Cheers

I had a similar situation a while ago (I think "while" could be 10 years ago) with a 2000 manifold.  Chris Witor sorted it out for a very reasonable price and it came back better than new.  I seem to remember he worked in conjunction with a machine shop.  If you are struggling it is worth giving him a call.  He does answer the phone.

Theres a mk2 manifold and carbs up on ebay starts at £50

 

have you tried used from places like TRGB they are now mainly TR but have a load used small chassis up in the store

Adrian, 138810 is for mk1 & 2. Mk3 has a fixed pipe so you just push the hose on and clamp it up. In the words of the Hitchhikers guide "Don't Panic!" All will become clear once you get the new bits.

Hi Adrian - Ive got a spare manifold for a Mk2 Vitesse , would this fit , heres a pic

Hi Doug

 

Yes am aware it is but the Vitesse has the same part. I can't find a part number. Does anyone know the thread?

 

Cheers

[Pete Lewis]

they are all 6 cly  are  the same thread , some of the adaptors may vary as time evolved 

 

take up Pauls offer

[Adrian]

OK - by way of update and hopefully conclusion.

 

1. Thanks for all of the advice - much appreciated.

2. Paul -Thanks for the offer of the manifold, hopefully won't need it but at least I know you have it.

3. Same with Colins offer.

4. I have spoken with Chris Witor. He said I had a rarer manifold with a cast inlet tube and to get it drilled out and install a 3/8 BSP thread to accommodate one of his stainless steel adaptors (I think it is the same as Pt 138810).

 

Hopefully it will be a straight install once the seized parts are out!

 

Thanks as always

Hello Adrian.

 

Well that sounds like good news.

 

Re: I have spoken with Chris Witor. He said I had a rarer manifold with a cast inlet tube  

 

​​Am I right in thinking that the manifold you currently have may not be the correct item for your 1972 GT6, or was it an option to fit one of these instead etc. ????

 

Just out of curiosity really.

 

Thanks.

 

Richard.

My manifold is the same, the inlet tube does not come out. I did say this earlier, but nobody listens.  The Canley diagrams show a screw in for the Mk1 & 2 but none for the Mk3. So, not so rare me thinks.

[Pete Lewis]

I hoid you, I hoid you

 

Rare..... does that put the price up

[dougbgt6]

Oh yes! Do you want to buy it? 

[Pete Lewis]

does the antiques road show have a forum  then   ???

I am here!

 

Ian Gittings is a top bloke. Proper engineer, makes (or made) the hub pullers and other such stuff sold by the club, also manifolds etc. 

 

Probably a lot less grief to let him sort it out, and it will be a proper job.

Could this be the same Ian who was an ace Manx Grand Prix motorcycle racer.on Ducati's ,if my memory serves me correctly

[Adrian]

Richard, Doug

 

The reference to rarer was Chris's words. Irrespective the fix is simple which is a great relief. Doug perhaps one too many pangalacticgargleblasters but couldn't find a direct replacement, now obvious as it was intergalactic to the casting.

 

Richard the manifold certainly looks like the mk3 one on canleys website. Seems silly having an integral part susceptible to corrosion, but I suppose the didn't envisage them lasting this long.

The Vitesse 1600, Mk1 2 Litre Vitesse and Mk1 GT6 inlet manifold has longer pipes, due to the shorter head on the earlier engine, than the Mk2 and Mk3 inlet manifolds. The Vitesse accelerator cable bracket tapped hole is not present on the GT6 inlet manifold. If you are after GT6 Mk3 inlet manifold ensure it has the central tapped holes to take the accelerator cable mechanism.

I found Ian Gittings. Went over to see him and dropped it off. His garage was an Aladdins cave of engineering, not to mention manifolds of all sorts. I'll post a picture when I get it back.

[Adrian]

Hello Chaps

 

I did say I'd update you on the refurbished manifold once I got it back from Ian. Attached are the pic of the full refurb.

 

Including - drill out old steel tube and replace with SS 

                 Remove old banjo bolt and retap (Chris Witor SS bolt bought 

                 Bead blasted and blasted through

                 All faces ground flat - slight warp, particularly notable on block face

                 Moulding flash removed

                 all threads cleaned and re-tapped

                 New brass banjo

 

Now only got to sort the engine - famous last words!

 

Cheers

That's too pretty to put on an engine, it should be on the mantelpiece!
