This is what happens when you do not change your oil

I think it ran quite hot. I did an engine failure analysis (Basically tear the engine down and see what went wrong) and found out that the lower intake gaskets where blown. Between not having any cooling and lack of an oil change - that's what ya get.

Yes - I am replacing the whole engine. Don't even bother messing with this one.

Ken - there was a TON of sludge/wax.

Yes - under normal conditions it does drop down to a lower viscoscity - but when it runs hot - it litteraly cooks the oil to wax. Have seen it very well on a neon that the head was completly wax-covered. (You could actucally chip away at it with a screwdriver)

For anyone wanting to know anything about oil (They go from what type to use when all the way down to the molecular level) visit http://www.bobistheoilguy.com Very, very good stuff in there!

I think this is the best you will get to tell if the engine ran dry. This was completly siezed on to the crankshaft. Had to chip it out with my air hammer!
