Pulled the engine for a quick preseason checkout. My concerns started when I pulled the drain plug, half a quart or so of water came out first. Pulled the pan and the bottom of the pan and the pickup were covered in the slimiest nastiest oil I have ever seen. Everything else is spotless. My question is this, does a race motor that was stored indoors (no heat, but never froze hard) on a concrete floor with open headers draw that much moisture and have this effect on the oil? Dont know where else it would have came from.:smt102

Doesn't take much freezing to break shit. I put anti-freeze in mine even though it's in a heated garage. There's a chance the fucking furnace breaks when it's 10 below zero. :rolleyes:

Do a pressure test of the water system.

That happened to me.I had a backfire at the line and it blew the intake gaskets last day at the track.Following spring I ran the car in the garage(didnt know it had blown the gaskets), went to pull the oil filter down and I got a bunch of water out of it.Condensation wont give you that much water.You better check those bearings cus I caught mine in time enough to only have to cut the crank and not buy a new one.

Unless you have run it I don't think the water in the oil is from a crack from freezing .You did say the oil looked nasty and that tells me it's probably been like that for a bit of time or a few runs anyways .I'd look @ the head gaskets or the intake gaskets . good luck .
X2, also, I put anti freeze in all my engines

If you using alcohol, it generates water as well. Take your valve cover off and see if you have water sitting in the lower corners. I get that alot as building heat is a challenge. I would not use antifreeze racing at all, believe its a rules issues as if anything lets loose it hits your tires and your in big trouble, fast, and its a bitch to clean up. If you want to add a lubricant, try a treatment like redline or royal purples.

Thanks guys. I had my heads checked and everything was OK. Filled the short block with hot water and looked for anything obvious. All is well. I guess Im just gonna clean it up and put it back together.

I had a bowtie block that ended up having a crack in the cam tunnel from freezing. The only time it would leak though is after you warmed it up. Then it would dump a bunch of water in the oil pan.
