Driving to work on Monday in my 1993 Discovery, the engine suddenly started racing. I pulled over to the side of the road with blue smoke pouring of the back and out of the bonnet with the engine screaming away at full revs. I turned off the ignition but the engine kept running. I tried stalling the engine, but it still kept running, by this time filling both carriageways with thick blue smoke.
After missing a sign post and nearly running into a ditch eventually, the engine stopped. I called on a recover service and was taken to a garage near my home. When the recovery driver spoke to his base, he said they had another similar case where the head gasket had blown between an oilway and cylinder 4, allowing the engine to run on it's oil.
The garage have just stripped the head off mine and found the same fault. Hopefully, the head is fine and it will just need a new gasket.
Anyone else had this problem, and is it common?
Alan.
