I really hate to tell you that it wasn’t a successful weekend for me.

 

At first practice one of the clutches slipped (gearbox or OD), the engine
went hot at full throttle and forced out water, the new starter motor
failed.

I replaced the head gasket and while torquing  up the head nuts nut #5
jumped one thread over. The threads were gone on that part.

I drove 200mls to get a new head stud, torqued it up and - BANG – the stud
snapped at the lower thread. It was one of the long head studs.

Now the thread was burried down in the block. End of race – I thought but
after I told my hotelier about the misfit he invented a head stud extractor
while I had breakfast. With that tool it took 10 minutes to get that thread
part out.

I recycled my old head stud, used 3 washers to reposition a new nut on a
different part of the threat and was able to torque it up.

Now the car was ready to race, temperature was fine at full throttle, the
car went uphill 133mph at 6000 rpm in overdrive! The car was smoking a lot
from the scuffed pistons which all 4 are scuffed, not only two as I thought.

The balance felt great and I was starting from behind and overtook about 15
cars in one lap.

Then a Healy driver pointed at my car and shouted that there is something
wrong with my car. I stopped racing and had a look at the engine.

A half a liter water was forced out – nothing else. Might have been a trick
to stop me because I did overtake him several times.

But after the whole field had passed me I retired and went to the pits.

 

I suppose that the water pump is spinning too fast at 6000 and start
cavitating which cause the water loss.

But the one race lap I did was fun  but not what I wanted – I wanted to be
more in front.

 

Cheers

Chris
