I've had a motor sitting in an old truck all winter. I rebuilt the engine, drove it to a friends house and parked it last September. Yesterday I fired it up and drove it back home (about 7 miles. It was then that I noticed that my oil was contaminated with antifreeze and water. I pulled the intake and heads but can visually see no seepage between the gaskets. Where would this coolant be most likelly coming into the oil?

cracked block or head are you sure the torque was right, some of the head bolts may have been leaking before you parked it it really wasn't that cold for a long spell last winter if it had antifreeze IMO

Eljojo, first off I dont know where your from or how cold it got, naturally it should have gotten a freeze plug first, but I have seen stranger things happen and Im sure you have too,But one of the weakest places on the block is under the intake,along the cylinders just above the lifter bores,usually the crack will run long ways just above the lifter bores...Wish you luck and I hope its somehting else....towman

What was wrong with the motor when you rebuilt it was tired or did something break?

Eljojo, are you sure it is water and antifreeze? Not trying to question you but, I had a similar circumstance. Turned out it was condensation in the oil from it never really reaching a good opperating temp. I changed oil, got the motor good and warm (190-210), and haven't seen the problem since. Just something else to consider....

Boys, the machinist I use is CONVINCED the water was leaking around a head bolt. His opinion is that, had I ran that rebuild for a while before I parked it, that everything would have sealed and all would have beed well. I've scoured the lifter valley, betewwn the cyls, and on the bottom where the cyls tie in along the pan rail-nuttin happinin there. The shop pressure checked the heads and they checked good. I guess I'll put some new gaskets on it and put it back together. I think I'l use that rollin' engine run-in stand (the street stock)and see if it'll contaminate the oil again. It's a bone stock old 350 out of an old van I've rode around in for the last few years...I bought one of those $154 engine kits from northern and some reworked heads and thought I'd have something----but it's so much trouble to put back into a van that, with the oil/water problem, I want to be absolutly sure there's no problems with it.
Thanks for all ya'll's (that's the plural of yall) help.

I lost a head gasket on a chev PU and every bit of coolant ended up in the pan.

Beware of those engine kits,i'd go with some good felpro head gaskets this time.

When rebuilding, I always put stop leak in rad before first startup.
