Ive taken off the rocker cover and everything looks fine but one of the spark plugs has its tip squashed a little!
I hope the engine isnt completely f***ed.
The worst thing is I spent ALL day cleaning and polishing the car and it has never looked as good. Its in show room condition almost which is why Im completely gutted I wont make it to Gaydon.

Looks like tomorrow Im going to be stripping the engine apart again to find out the damage!
