I am the very proud owner of a 1994 BMW 850CI, that I purchased in the canada. almost 6 months ago and am curious to know from any other 850CI owners if there are any Cylinder Head problems I should be aware of.
Apparently, on mine the Cylinder Head was replaced a couple of months before I bought it and I would like to know if this is likely to be a recurring problem. thanks

I don't know about this specific vehicle but the usual cause of cylinder head cracks is overheating (ie letting the engine run without sufficient water in the radiator). you have to check the cooling system regularly.
