Would you believe it? Had the motor to bits four times now over the past few weeks, reamed all the guides, valves running with plenty of clearance, sorted the fuelling problem out this morning, went for a lovely drive, got home, left the car for a couple of hours, started it up again clack, clack, clack....

After a couple of minutes warm up the valves freed up and the car went well.

I’ve been running the car on Premium E5 and noticed that there were all sorts of gummy deposits around the inlet valves...do you think a change to cheap petrol may help?

I’m going to drain the oil and switch to Classic 20/50 instead of straight 30 as well.
