I have a small headache bugging on me, some gunk was found to deosit on the coolent cap after some driving. Some one told me that its might be a cracked engine cap or engine block or head gasket, which is very expensive to repair. Another friend told me that it could be a leaky tranny coolant valve, and cheaper to repair. Do you guys have any idea on what might be wrong?
Thanks and Happy Year 2001.
