Another question on my 67 Mustang...

Sucked up everything in site immediately after the pics.

My plan was to get the heads done, put em on, put in new plugs, change the oil and filter and THEN fire her up. Not a good plan?

Did you even check the compression of the Cyl's first?

You need(should have) to find out what is wrong first beofre you start pulling your engine apart.

I didn't compression test the engine, quite frankly because a good friend of mine told me not to waste my time.

I'm pretty sure the issue lies in the head gasket. Going to get the heads re-done while i have em off, and then put the car back together. If that doesn't fix the issue, I'll go from there. Not sure what else I can do at this point...

Some systems won't drain well. You need to remove radiator hoses or the plugs in the block. There is one in each bank, down low near the oil pan rail. But you should have opened the petcock on the radiator and drained it into a pan at the very least. I know you were probably trying to minimize the mess but .... You're OK though, no biggie.

Yes, that's what I was trying to say. Change oil and filter first.
Me, I would run it awhile and change them again.

You have a manual with valve adjustment procedures, torque patterns and torque specs for this job I hope. It's kind of a big job and I'd hate to see you have to do it over.

Myself, I think new gaskets and freshened up heads will solve your original problem.

Newer cars will run coolant through the intake manifold to assist in warm-up. Older cars often ran exhaust through the intake to accomplish the same task. If yours is of the coolant variety, I would be looking at the intake gaskets as the possible source of your leak. I realize they're going to be replaced, but you might want to take a look if it's not too late.

As others have alluded to, and as it sounds like you've already figured out, you've had coolant getting into the crankcase.

Not driving the car often and/or not driving long enough to thoroughly warm it up can lead to water mixed into your oil too. Water vapor will condense inside the crankcase just as it will on the outside of your car when the dew-point is high enough.

That car should have a PCV valve. Be sure to check or replace as needed. Make sure the hose and passage into the intake manifold is not blocked with carbon or whatever. You want to have nice fresh clean air circulating through the crankcase. If there is a breather filter in the air cleaner, replace that too. Sounds as if it's too old for that. I can't remember what year(s) they starting using those.
