I think im just terribly unlucky, the puddle was small, walked through it afterwords and only came 1/2 way up my shins. pulled all the plugs and spun motor, made a loud clunk and nothing more. I had it towed to the house and will try to pull the heads this weekend and look for valve damage. May part out, may sell to salvage yard, buddy of mine is a buyer for LKQ and offered 2k as it sits so we shall see. My wife is more PO'd than I am. I just went in to pull a buddy's s10 out (he got stuck) pulled him out just fine then this happened.
Oh, and the truck is BONE stock. even had OE plugs still in it, air filter was soaked and weight about 10lbs seemingly.
