My dad has a 2000 Bonneville. I have noticed some leaking oil on the ground, and it looks like some antifreeze junk appears to be evaporated under the oil cap. First thing that popped into my mind is head gasket. I talked to him about it and he said he knew about it and didn't think it wasn't a head gasket. I guess the dealer said something about a different gasket.
I know there are some common problems with the 3800 and I don't think a head gasket is normal and he drives rather conservative.
You can probably tell what it is, if you could give me a wirte-up for it and a parts list that would be great. I'm going to attempt to fix this up since he got a new car and I will probably be using it for college.
Car has ~130,000 miles btw. Gas gauge is broken and I might try to tackle that DIY also. Any common things that go wrong that would be easy to replace would be great.
It needs a tune up too since my dad has pretty much neglected maintenance on it. Spark Plugs, Fuel Filter, Air Filter. Am I missing anything else
