The MGB Heater Valve that takes hot water from the head and routes it through the "heater core" radiartor leaks sometimes... and when it does it leaks directly onto the distributor or squirts a stream onto the alternator - neither a good choice for an endurance race car.
The one pictured below, from a 1978 MGB-GT, leaked onto the distributor. Time to go. But what if you're too cheap to buy a $15 nice looking blanking plate for it? pfft.
Follow Gormless Racing's easy 5 step process.
1) Remove said craptastic valve, mock liberally:
2) Hack saw into two pieces, removing the 'crap' part and leaving the 'tastic' part:
3) File, Grind, Cackle, Tap (that only counts as one step, but you can use up to a full case of beer if done correctly):
4) Douse with thread sealant, use lock washer, bolt, and newish gasket:
5) Install, enjoy:
Thanks for sharing this information with the picture descriptions. These pictures are very useful to set the valves firmly.
