Bought 1999 Venture Minivan used with 7400 miles on it almost three years ago now. Up until now it has been a pretty good vehicle with only some minor warranty repairs. However it now has almost 60,000 miles and about 2 months ago it started loosing antifreeze out of the reservoir and during this time period added almost 1 gallon. Since we could see nor find no leaks we took it to the shop to see if problem could be located. Alas the coolant has been seeping into the engine,(evidence by white gunk on oil cap, but no sign of water in the oil) suspect through intake or head gasket and it appears the engine may be gone if bearings are wiped. Don't know yet because had it towed to Chevrolet dealer who is going to check it out on Monday. Since the 36,000 mile 36 month warranty is out we are worried we will have to pay for new engine. Anyone else had this problem? Discussion with shop and Chevrolet dealer indicated this engine is known for this. I called the consumer service number but have to have it evaluated by Chevrolet dealer before they will tell me anything.
