2 petrol heater valve

Got the head on and now refitting all the bits and bobs.

The heater valve which fits into the rear of the cylinder head - when I
screw it in tight, the stub for the heater hose is facing forward. It needs
to turn another 180deg to enable the hose to fit. I've annealed the copper
washer to see if it will swell up a bit, but still it won't face the right
way.

I could fit another washer so it tightens sooner, but it was fine with just
the one when I took it off a couple of days ago.

Am I missing a trick here?

It should be a collapsing washer - one use only. If you can't get one of
these, use PTFE tape or something to assist in providing a seal when it's
not screwed home.

Only one suggestion. Unscrew it carefully until it just clicks - the
threads disengage and drop in. Then tighten. I've used this trick on one
or two things, but it may be the threads need to be particularly fine
pitched for the diameter.

I not a big fan of PTFE tape in cooling systems - bits have a habit of
floating off and clogging things up, although OK in an emergency. In the
end I discovered the right washer - the local factor sells them as sump plug
washers, which is why I couldn't find one. Once I had the correct washer,
the valve fitted perfectly.

Thanks for the help, all.
