How can antifreeze get in the oil before the engine is even started, other that being poured in it ?

The first thing that comes to my mind is a badly cracked head or block. Could be a blown out head gasket too. You can do a leak-down test on the cooling system to see if that is the problem. I could be wrong though.

This is a freshly re-built engine, so I would be really disappointed if I have any of those problems, probably more like pissed. No hours, just got it primed and it looked foamy. I am really disappointed in this mess so I guess I may have to tear it down and start again. If I have to keep spending money on this thing, I think I might have been better off to buy one of the 10,000 dollar stroker motors on E-bay. This sure is fun.

This sure is fun.One other direct passage of water to oil is if the front timing cover gasket is not sealing and allowing water into sump. have you checked plug holes for evidence of water when cranking over, it may isolate cause of problem.

Number seven had a rusty plug, but I have not tried to turn it over, except by hand. I guess it is time to pull the head.

Y-Guy Catus: You were careful not to mix the head bolts right? Some are longer and they may have bottomed out, and not let the gasket seal. Look at Mummert's site and use his "check list" on assembly errors. Just a thought Bill

That could be the answer, but I did not put this motor together. I will have to check when I tear it down.

My engine was put together by a respected shop and they still put the head bolts in wrong. So I had to pull my heads and redo them. Did you put sealer on the bolts in the timing cover? Some go into water jacket. Good luck!

This is something that happens to marine engines all the time.
The easiest way to detect a leak is to pressurize the cooling system and listen.
you can listen at each spark plug hole with a stethoscope to isolate it....
Sorry about that....

If I simply drain the oil ( Break-in) and replace it, will I eliminate enough of the Anti_freeze to avoid destroying the bearings and the cam?

That would probably work, but I would put in some new oil, turn the pump with a drill and drain the oil and change the filter again just to be safe on a new engine.

Thanks, that is what I thought. After I discover my water leak, hopefully I can get this thing started.

Well, I finally pulled my heads and found water in all eight cylinders. I suspect my builder put the head bolts in the wrong holes, (unfortunately I could not be there when they were pulled, so I don't know) and I am going to take them to another machinist to see If I have enough meat left to clean them up. You can see that the head gaskets never compressed properly. I hope for the best, but if not does any one know of any good G heads that I can get for now, until I save up enough for John's heads after this setback.

Did your builder use the original bolts or did he use new ones? I would check the lengths on all, they may all be too long.

They were all new ARP bolts from Mummert.
