the odd thing is that the drumming sound is just like that of when my head gasket went. now my mate did the head using top notch gasket and bits cleaned it all and resetup carb and timing. its run fine for three hundred miles. after its hissyfit tonite i drove it half way home about five miles to find it got very hot and dumped its water out of overflow. when rac turned up the guy (who claims to know minis) said he was certain that its my big end gone. brother in law looked and said that if it was big end it wouldnt tickover as well as it does. he thinks carb(also new) is malfunctioning causing the drumming sound and due to ill running caused it to overheat.
finaly there was oil on floo under rear of engine at its final resting place. not a lot but enough o make me worry.
the noise is definitely radiating from the carb direction drumming popping sound. thanks
any ideas

Was the head re-torqued after being run for a while as recommended?

I'd be surprised if the Big end had gone - They tend to rumble, then start banging - the noise comes from lower down the engine.
My first instincts tell me that a valve has stuck open in the head.

if its blown in the same place then somethings wrong or it wasn't fitted properly.
