[TR] TR2-3-4 Engine and Rad Taps

[Kinderlehrer]

Hi Brian,

Moss's response to the leaking issue was "they all do that". It's been many
years since I had this same issue. I solved it by taking the valve apart and
polishing the parts. I don't remember how I polished them, maybe it was
compound or 1500 grit wet/dry sandpaper.  Some PTFE on the threads that go
into the block or radiator also helps. Anyway, no drips since.  I had to do
this on 2 radiators. 

 

The other alternative is to use a "modern" petcock.

 

Hope this helps,

 

Bob

Hi,

 

I'm having great difficulty getting either of the drain taps in the TR2 to
stop leaking.  I've tried various used taps from my 45+ year "collection"
without any success.  The taps leak mostly out the drain hole but some also
where screwed into the block/rad.

 

I recently ordered a pair of new replacements from Rimmer with high hopes
but after install, both leak from the side opposite the lever - see pic.
This is with antifreeze in, rad cap off and no pressurization.  I've asked
Rimmer for comment, but they are closed until Tuesday (bank holiday Monday).

 



 

The pic is shows the engine install with the spring portion "up" - that's
what it tightened to.

 

Has anyone had success with current offerings from the various vendors?  I
see Moss also offers them - others?  TRF doesn't currently have them. 

 

I'm about to give up and try the Don Elliot solution sealing the taps where
they thread into the block/rad.

 

Appreciate any suggestions.

 

Stay well and cheers,

 

Brian
