Free 4.0HO!! Should I get it???

I have access to a free 4.0HO out of a Cherokee. The oil pump went out and it has a thrown rod. There is a hole in the block, but all brackets and everything else is there. Head, valve cover, intake/exhaust manifolds, fuel rail, etc.... What kind of damage could the head and valve train have as a result of the bad oil pump? The engine was running fine until the pump went out while running at highway speeds. I was thinking of keeping the top end and brackets for a later head swap or complete 4.0 swap. I don't want the whole engine laying around so I will probably pull the good parts and head to the scrap yard. Would the head be in decent shape even after a little oil starvation?

Thanks,
Tom

1. It's free! Get it!
2. When an engine starves for oil often the first parts to will be something in the head... as the oil pump can no longer pump the oil to the highest part of the engine. These parts heat up and fail.
3. Pull the valve cover and look for bluing or damage to the cams, rollers, valve stems, etc.

What's ya got to loose? Me, I'd be there in a flash to pick up that pile of junk! [img]images/graemlins/grin.gif[/img]
