[Healeys] Heater query

[m.g.sharp at sympatico.ca]

I agree with Kees; over here it is called plumber’s grease and I have used it for years on both the brass taps on British cars and the fuel taps on my old bikes, which are or identical design.  As Kees says, it works a treat.  It is available at most hardware outlets that sell plumbing fittings.

One should use what is in Europe known as "Hahn Fett" which literally translates from German to "Tap Grease". It is a graphite or perhaps molybdenum based grease which is used to lubricate all kinds of taps.
I have used it for years for domestic, industrial, automotive taps.

Yep. Also, the cone part is held in with a spring under a washer held with a small cotter; you can use a thicker washer to get a bit more 'pull' on the cone. When I have one out, I put a thin smear of wheel bearing grease on the cone to help prevent sticking.

I got 'too-clever-by-half' once and used valve lapping compound on the cone; it visibly scored the cone though it still sealed. Very fine wet/dry sandpaper works OK.

The leaking of the valve may improve if you lap in the cone with e.g. Brass Polish.

I agree…the handles are pretty frail. My heater one was solid. The one on the block was likewise solid and the radiator one had been swapped out for a simple plug.

I took them apart and redid(?) them. They loosen up OK if you tap the cone shaped inner part outwards. I made my own handles which are too big, but they serve.

“Heater valve” shows the valve looking fine but jammed solid. “Figure 3” shows it after I bust the handle and then cleaned it all out and replaced the handle. Of course, if I’d known to tap the centre through the valve, I’d never have busticated the handle in the first place ………..

(If anyone wants, I could send a few pages on how/why I did what to those valves).

Incidentally, I bought a good looking radiator valve on eBay. Useless, it dripped from the moment I screwed it in. Back in the box. Quite recently I noticed that Ahead4Healeys , I think it was, had them pictured on their site but said that they were withdrawn because they all leaked. See “Radiator Tap”.
