the escos started burning oil last week,it was on the dyno at thor on monday and the engine was compressing quite badly. took the cylinder head off today and there doesnt seem to be any piston damage .hopefully the fault is in the cylinder head that will get stripped down later tonight.now my problem is getting hold of a new coopers ring gasket.has anybody tried the ferriday alloy gaskets?are they any good?any traders going to the show tommorow that can bring one?
