Heater Pipes

[Orlando St.R]

My dad clearly used some plumbing copper pipe to replace the bulkhead heater pipes at some point.

The restorers clearly decided these pipes were beyond redemption and replaced them with a mish-mash of parts off various Jags, which worked well enough. I hadn't really looked too closely at them until I tried to fit the scuttle vent pipe BD10370 and found it wouldn't fit.

I decided to tidy things up by fitting stainless steel pipes from SNGB, part number HTP7SS. These fit well behind the engine, but the heater-valve-to-heater-box section of the lower/front pipe is too long and I had to lop about 2in off the horizontal aspect. The upper/rear pipe is also too long and finishes at the wrong angle compared to the heater hose elbow. Rather than rip it all out, I sourced a suitably shaped elbow from a Vauxhall. But, if I'd known it was wrong beforehand, I could have taken a trip to a friendly plumber to reshape the heater box end.

However, the result looks quite neat and has allowed me to fit the scuttle vent tube and route it correctly.

Great job Orlando. I also used the stainless pipes from Barratts ~ we fortunately had no fitment problems. (maybe they got a piece from another kit muddled into yours). Old steel pipes rusted through. Good to see you have your scuttle drain in. Looking very neat & tidy.

Hi Glyn. Yes, yours do look a better fit. I'm about 90% certain it's the right pipe; just not bent properly.

Yes, the scuttle drain is in, thanks to your guidance!

Always a pleasure. What threw me was you having to cut the pipe. I don't remember us doing that. But hey that might just be my tired old brain. On reflection I do remember us having to reprofile a bend slightly on the carb side of the engine. I'm battling with a slightly sticky throttle without having to run a stronger than standard rear spring ~ always something. I'm trying to learn SU constant depression carburettors 101 in a hurry. I'm a twin sidedraught Weber & Dellorto man. SU's are a mystery to me.

Hi Glyn - There's not much to SUs once you get the hang of them. And the settings do seem to last for ages. There's lots online and several books.

I should have put a link in, which is: https://www.sngbarratt.com/uk/#!/Englis ... a0d690df4e

I do not think the drain hose is routed correctly as shown in the picture.

In my car, the original deteriorated hose was behind the cam cover, inside the bulkhead / firewall "cutout" where the transmission joins the engine, at a 90 degree angle downwards from the pipe to the ground.

the way you have it, it is outside the firewall cutout towards the heater valve at an angle that defeats draining somewhat.

I have not been able to get a picture of mine because the car is in a dark storage. I tried but all I got was a black picture.

Hi Glyn. Perhaps when you get your car in the sunlight next, you could try again for me with a pic of how yours is routed. Unless you have any old pix from before restoration. I have no body tabs within the gearbox tunnel and it is pretty chock full of BW DG autobox! No urgency; I won't be using it much over the next few months; they have started gritting here, though I can't really complain. We've had a much-extended salt-free season.

I would like to install those in my car but if you say they don't really fit, I think I'll just send mine to get them blasted clean since they are not rusted.

[Orlando St.R]

If yours are in good condition and not too furred up inside, yes, you might as well keep them. Mine were just cobbled together, so they had to go really. I think having the SNGB ones corrected would be pretty easy if you lived near a friendly plumber or exhaust shop. They're not far out. I've also provided feedback to Peter Stant at SNGB, so hopefully future sets will be more accurate. He must dread it when an email arrives from me!
