Hi,
My '94 M43 appears to be blowing water (coolant) out the exhaust. I don't see any blackening of the remaining water or see any water in the engine oil? Could it still be a head gasket? What else could it be? Is there another way that it could be getting to the exhaust? I'll pull the plugs tomorrow and see if there's a difference between them? Are head gaskets or anything else that could cause this a common problem for these engines?

Thanks,

All spark plugs look the same. As background the car sat for six months or more before this. No external leaks. I've marked coolant level to see if it as moved when it cools down. Coolant also looks clean?
