[Healeys] JB8 Stuck Heater Valve

[Andy Thorp]

Loctite on the tapered seat upon final assembly is a good way of ensuring it doesn't leak, however the obvious down side is that you then can't turn it and expect it to stay sealed. Great way of stopping that pesky antifreeze weep if you don't plan on actually using the tap.

A propane torch and a light tap on the bum will free a stuck tap, also gets it apart after the loctite treatment if necessary.

 G’day  Which reminds me!  In the process of getting the
 Healey Duncan going I disassembled, cleaned and polished the
 brass ‘tapered plug’ drain tap and it looked very pretty
 against the gloss black of the engine. One problem is that
 it didn’t seal!  So out it came and with much
 physical action with a cloth and Brasso the tapered joins
 were polished. Then when assembling it received the gentle
 hammer treatment in the hope that it would seal. It
 didn’t!  In the end I removed the tap from
 the BN3’s engine and used that which worked
 perfectly.  The tap fitted to the Healey
 engine is more ornate that fitted to the Austin-Healey but
 apart from more work with Brasso I’m at a loss at what to
 do.  Thanks  Patrick QuinnBlue Mountains,
