Default Oil Leaks

Okay, so I apparently have two oil leaks. Both Valve Head Gaskets are gone and the upper intake is leaking oil. Come to find out, my new step brother has two Bonnevilles (1996, 1993) and has agreed to do the work for a couple cases of Bud. My question is, what exactly do I need to get parts wise? I've never done any engine work like this before, any pointers for us? Thanks.

Have you read the techinfo article on it?

http://www.bonnevilleclub.com/forum/...e=article&k=38

There'* been many posts regarding it, also. A list of things is supercharger gasket, coolant o-rings if not part of the gasket set (Felpro includes them), throttle body gasket, valve cover gaskets, GM aluminum framed LIM gasket, and coolant elbows available on the Dorman Help cards at most autoparts stores.

Opps...sorry, I forgot all about checking the TechInfo. Secion. Looks like a much bigger job then I gave it credit for. Thanks Archon.

Has the cost gone up to 4 cases of Bud now? It'* not really a hard job - just lots of detail with things in the way. If he can remember where everything goes...you should be all set. However, you may want to consider either a factory service manual (often available on ebay) or a subscription to http://www.alldatadiy.com/ Lots of diagrams, and step by step instructions.

If your step-brother has done the other two bonnevilles you mention, he should be able to do it in 3-4 hours.

Without air tools, I did an L36 in 2.5 hours solo.

I can do my L67 top ends (same as yours essentially) in under two hours with air tools. Take pics and tag items. Sort your fasteners. Makes assembly much quicker.

Thats a good idea. He seems to know what hes talking about, at first he thought he could just tighten the bolts on the gaskets, but when we knew that wasn't the problem he generously offered to do the work. Hes been doing his own engine work for like 20 years, but this is my daily driver, so I am a little apprehensive.
