Yep the van is getting a major overhaul... I checked compression on all the cylinders and they were almost identical - not bad after 270,000 miles and original head gaskets. So I decided to do upper intake gasket, lower intake gasket, throttle body gasket, injector o-rings, oil pan gasket, oil pump tube gasket, valve cover gaskets, valve seals, and downpipe donut and what ever else it needed once I'm in their. This will keep this engine running great until the trans dies then I have a little S2 L67 just sitting here that is wanting a home.
The only reason I wanted the AC Delco part numbers is because I basically get the parts at cost - one of the many perks of having a girlfriend thats dad owns a Cadillac Dealership.
It is amazing how reliable this van is, it makes a trip to Rochester, MI from Bolingbrook, IL every weekend (650 miles their and back) and still finds a way to get 26-28 MPG. It has been basically a free ride since I got it because allmost every part on it is lifetime. The thing drives/rides better then most cars that have less then 75,000 miles and the body doesn't even look like it has 100K on it.
