Re: New Exhaust manifold - bad fit

A note to anyone considering buying a manifold from SNGB.......... They don't fit! I sent mine back to them along with the original for their technical dept to compare and they agree that they have been machined at a significantly different angle. If bought as a pair then they will align together, b...

Re: New Exhaust manifold - bad fit

I’m having a job sourcing a non-SNGB manifold. The last 2 places I’ve tried have both sent me SNGB ones. Neither are better than the one I’ve posted a picture of. My conclusion is that their casting is not as per the original and needs modification. In the meantime SNGB have taken their one back alo...

Re: Air conditioning experiences

Hi Ole, Thanks and sorry for my misunderstanding as I didn’t read your post properly and thought you’d used an ally compressor. Glad your original one works well! :bigrin: Will post up my impressions of my lightweight one when I finally get the funds to get the system rebuilt. Til then, thanks for a...

Re: Vacuum Pipes on series 3

Hi Simon, It's been so useful for me to hear everyone's advice. Just on this one small detail, I've learned such a lot about things that up to now have seemed like a 'black art'! Perhaps for me, a little knowledge may be a dangerous thing, but I believe that now I can try things out with an understa...

Re: Air conditioning experiences

Hi Ole.
Thanks for the reply.
My update is actually exactly along the lines of what you’ve said:
I’ve just bought an aluminium compressor as it was cheaper than getting my original one rebuilt.
Do you notice any benefits other than the obvious weight saving over the original?
Thanks again,
Hilton.

Re: New Exhaust manifold - bad fit

Good advice Mark, thanks.
I’ve checked the ones I’ve got and they look like the premium one you’re talking about.
Let’s hope I can find a manifold that’s fit for purpose, then I can get them fitted on the engine.
Cheers, Hilton

Re: Vacuum Pipes on series 3

Good thinking Colin. I stuck a new filter in a couple of weeks ago just in case. Still got the random weird power loss..... Once I’ve found a place that sells an exhaust manifold that actually fits properly, I’ll get the car running and test out all the above advice and see where I get. Thanks again...

Re: Vacuum Pipes on series 3

Thanks Mark, It was my understanding that the SNGB ignition was a direct replacement for the original ie. retard so left the vacuum pipes as they were. I shall remove the vacuum pipe that currently runs to the inlet manifold and blank everything off. Can’t think why it should have been connected to ...

Re: New Exhaust manifold - bad fit

Thanks Mark. I see exactly what you mean. I did manage to get the suds through with enough thread for the nuts. I haven’t got the facility to mill them unfortunately and don’t want to have to remove the other manifold to get it paired. Though I suppose I can judge how much the new one needs milling ...

Re: Vacuum Pipes on series 3

Just checked under the LH rear carb and the tapping has been blanked off.
So I should disconnect the vacuum feed the the distributor vacuum retard then, right?
Thanks,
Hilton.

Re: Vacuum Pipes on series 3

Hi Simon/Colin. Thanks for all your attention. This is all very interesting. Since reading the latest 3 posts I haven’t been able to look under the LH rear carb to check for the retard feed to the distributor (and check whether capped) but shall do so ASAP. So, in summary, if my distributor has the ...

New Exhaust manifold - bad fit

Another in my catalogue of woes- sorry. I’m replacing my RH rear exhaust manifold as part of it has cracked and a chunk has come away. Anyway, I bought a new replacement from SNGB and fitted it today, only to find it doesn’t align with the front one where they link to the down pipe. What’s more, if ...

Re: Vacuum Pipes on series 3

Hi Colin & Simon. I’m afraid I’m hopelessly undereducated as far as retard/advance pros and cons go, so can’t comment. All I can say is that my ignition is the original set up with the vacuum retard and understand the compromises of this. The vacuum feed for the distributor comes from the rear of th...

Hi Simon. Here you go. (And sorry for the rubbish annotations - I’m on my mobile!) LH & RH rear inlet manifolds showing the vacuum tappings we’ve been talking about. The other two feeds are for the distributor vacuum and the servo feed. See what you think. Oh, my carbs are Strombergs. Cheers, Hilton...

Re: Vacuum Pipes on series 3

Hi Simon.
There are other tappings for other uses but whilst everything’s apart, I’ll take some photos as my explanations aren’t always so good!
Will be back later this morning.

Re: Vacuum Pipes on series 3

Thanks Simon. All this really helps. I found the small tappings which are hidden under the larger balance feeds that have the rubber ‘T’ vacuum pipe between the two manifolds. Veery hard to spot if no pipe connected to them. On mine they are only on one manifold per side of the engine. One side had ...

Re: Vacuum Pipes on series 3

Hi Simon, Thanks very much for the enhanced explanation - really appreciate your edit. It's de-mystified what those parts are actually for. I've had a look at at the various parts on mine as I've got them all dissembled at the moment. The flap mechanism seems to work under vacuum(it opens/shuts by s...

Re: Vacuum Pipes on series 3

Hi vee12eman You mention that "air is taken from trappings on the manifolds, difficult to access and that goes into the temp sensors". Can you describe which part of the manifold it the trappings would be(presume exhaust manifold?) - I've got the manifold all exposed at the moment and can't see wher...

Re: Air conditioning experiences

Well, bit of a disappointing day today. Turns out that the clowns who did some restoration work under. the bonnet just disconnected the system and left it all open whilst they were working on it. Consequently, the hoses have all sorts of cr*p inside them. The Compressor is seized and the condenser h...
