During a regular oil change my mechanic discovered oil in the anti-freeze. Head gaskets went out. My mechanic states they have seen in almost every 3.4 Pontiac Montana mini van that around 80,000 miles there is oil in the antifreeze which indicates a head gasket malfunction. Took mechanic 3 days to fix my van to a cost of $1212.83 plus I was without a vehicle for 3 days. At about 79,000 miles the wheel bearing went out. Now the slider passenger door won't open or won't close at times.
