Overheating RP
#1
I have a problem with my RP, which boils its coolant after less than five minutes at a moderate tick-over when stationary.
 
The story so far:
 
In the past couple of years the car has been almost unused, clocking up only about 130 miles. In June I "borrowed" its carburettor to get the van to Beaulieu, eventually replacing it on the RP.
 
Taking it out on a test run, after five minutes I noticed oil pressure dropping to zero. A quick look under the bonnet showed a massive oil leak at the front end, couple with ominous bubblings and hissing from the radiator. After letting it cool down, I limped home.
 
Stripping the engine down, no obvious signs of damage, other than the oil leaks. No sign of damage to cylinder head or gasket. Big end, main bearings and everything else OK and running freely. Tooth missing on smaller timing gear - gears  replaced.  Block, head and radiator flushed out with garden hose - no obvious blockages.
 
Engine reassembled (silicone gaskets) and installed. Fired first time and ran well with no obvious leaks, then began to boil. Mixture, timing and everything else checked and satisfactory - mixture actually slightly rich. Water seems to be circulating normally
 
Any ideas? Is there a sort of "reverse Radweld" that might flush out an unsuspected blockage? Has anyone experienced anything similar?
