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

[Stan Foster]

The new engine drain tap leaked when I rebuilt my TR3 engine. I took the tap apart and lapped the tapers together with toothpaste until all surfaces looked even. It did not take long. No leaks in 6 years and the engine still has that minty fresh smell.

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
