Re-furb'ing heater valves.

Alan @ CanfordClassics · Wed Apr 04, 2007 9:15 pm

Hi,

I needed a few heater valves (the item which your heater cable is attached to) and when I tried to get some it proved difficult. You can buy aftermarket ones but the new Porsche ones are different than the ones used on pre 73 cars.

So I restored some….. I know it looks like I have too much time and need to get out more

Before

After plating and powder coating

Back together and now very useable

Thanks

Alan

Doing this means you can drive it in winter, as well!

Hi Alan. Nice work - really fectory-looking result. Love it

I recently crawled under the car to look at mine. The rotating cover plate is as rusty as the heat exchangers were, and I managed to punch a hole in one whilst I was getting them to rotate again. Whilst I was down there, I put new springs on them, although the control cable snapped (v rusty, and sharp, and easy to stuff into your finger

), so I ordered a new one of those.

The boxes themselves are OK, so can you just buy the rotating cover plate bit on its own. I'd also like to try not to take them off the car as I know about the studs snapping...

Also, what's the black spongey, shiny gunk that's everywhere under my car, and I can see in your first picture?

I don't think it is - mine is crispy foam, a bit like that oasis stuff florists use.

sounds more like some sort of insulation ?

Alan do you own a powder coaters/platers firm? either that or you are keeping the local ones very happy and busy.

Good work fella.

jamie

yes you can buy the rotating discs seperately

I got mine in my last order fom Mittelmotor, but Porsche will sell them too

I'll post some pictures soon as I have just re-built mine

Hey Alan - nice work as usual - painfully thorough! I recently painted my valves while the engine was out and they wer ereally close to Koni orange/red. Is this a SWB vs LWB difference?

Alan @ CanfordClassics · Sat Apr 07, 2007 7:57 am

Hi,

Thanks for your kind word - Nige - I am at the platers/blasters/powder coaters... quite alot

. They are all very good at their work but some still like to tell me the old story "of how a Porsche is basically a VW".. If I had a £ for every time I heard that!

Hi Bob- I hope you are well? I think you might be right as I have recently seen the heater valves on a 66 & 67 car and both were the red as you described.

Yes - my car's a 68 swb and the heater valves are red - mine are Ford Signal Red actually now, believe it or not, I took them to my paint supplier to photomatch the colour and it was a 96% match
(And you think you need to get out more..............)

These are the flapper boxes from my car

I had the originals blast cleaned and ordered new rotating discs (from Mittelmotor as it happens)

the old boxes were not too bad, although the original yellow zinc plating was lost (except internally) and the red paint (not powder coating) was very flaky, however as you can see in the picture the rotating discs were too rusty to be saved

I have painted them with 2 coats of POR-15 and also painted the new discs the same as they came with just a black primer

I realised after painting them I had been given 2 right hand side discs.....

, so as I now have a new one (they are around £7 from Porsche) on order if anyone want a single right side then let me know

sorry
after looking at Alan 's photos i think I have tried to put mine together the wrong way, so in fact I have a spare left side
