Question about 1999 Buick Regal
Some where you have lost integrity of the cooling system allowing it to enter the crankcase. If the coolant goes directly into the oil, the problem should be obvious. If you send the year, make and model I may be able to help you locate it. If it overheated, the cylinder head may have cracked.

Its a common problem, but it has to be adressed before your engine is done. That oil is comming out wear the distributor wonce was. The plentem, or what you call upper intake will have to come back off, in order to get the plug out to chg. the rubber O- ring on the plugWhen you get it out it will look like half a distributor with the gear on the end and the O- ring towards the top. Its located right under the throuttle on left side of engine where the trans and block meat. There might be enought room to get it out without pulling the intake i'am not sure. But thats where the oil is comming from manny an engine has tied up because of that leak.

have you checked the pcv valve and hose to see if motor vacuum is venting the pressure if not press. will build - could be causing your gasket leak problem?

this is a water pump bypass hose connector to the manifold, take the broken piece to a parts store and show it to them, it should have the threads still broken off in the manifold so explain that. To remove the broken piece ask for a EZ OUT to fit the piece you took to the store.
It is common for these to become brittle and break off but it is a simple fix.

it is a great deal of work. The molded gaskets breakdown with time. You'll want to change the two 90 degree elbows as well - they are available from a dealer for a reasonable price. Also, the blower gasket is likely shrunk up and /or blown out. And you might as well replace the valve cover gaskets too as they leak oil as they breakdown with heat and time.
I did all of this on mine. Even as a professional, it took me a good 6 hours.

If the coolant is leaking at the head gasket or the intake manifold gasket slowly, then new gaskets will have to be installed. The bubbles coming up is a bad sign that the seal of the coolant system is bad or it's overheating the coolant to the point that it boils over.
The overheating may be due to air or vapor in the cooling system not allowing fluid to flow freely.
Did you put a 50/50 concentration of coolant to water into the cooling system?
Also, check the fan to see if it is turning on when the car is at operating temperature at idle.
May need to be flushed out and new coolant installed to increase cooling efficiency.
Good luck on this repair.
