water in d8 pony motor oil

Can you post a photo of the bolts you tightened so we can identify when the leak was.

OK. i wont be able to post it until tomorrow night.

here are pics of the left and right side of the coolant manifold bolts that came loose.

Seems to me about the only way you could get coolant in the oil is through a bad head gasket or cracked head or block. I don't think the line flange bolting has anything to do with it. Do you live in cold winter country?

yes, I live in Northern IL, but I run 50/50 coolant mix in the block. I am afraid it might be the head gasket or a cracked block if water cant get down through the flange bolt openings. I was just kind of hoping it was the flange bolt openings since that would be a whole lot easier! I am going to do a compression check to see how much compression I have in each cylinder next. Any idea how much compression there should be? I'm thinking 80-90 pounds at least.

They might make 80 psi new but I'd say you'd be doing good to get 60 to 75psi and I've seen them old buggers still do the job at 40 psi.

Thanks. So if the head gasket is bad or the head is cracked, that would show up in a low psi wouldn't it? I don't ant to pull the head if I don't have to.

yep low psi means there is something wrong in there!

Not necessarily, depends on the size and location of the crack or leak. Are you getting any bubbles at the radiator neck?
