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

[DAVID MASSEY]

 I had the same issue with a replacement I installed in the TR3.  I wound up soldering it closed.  It has become a plug that looks like a drain valve.
I think (Haven't tried it yet) that if you take some valve lapping compound you can grind them into a tight fit.  Something the Pacific Rim Manufacturer didn't do.  (They were low bid, after all)

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 _____________________________________________________ Brian Thomas                           E-Mail: Brian.Thomas at QueensU.Ca 92 Wyona Lane                         Phone:  613-385-1947 Wolfe Island,  Ontario               Toys:  54 TR2,  56 TR3,  67 TR4A,  Canada  K0H 2Y0                                   01 XKR, 75 John Deere 920    ** triumphs at autox.team.net **
