Coolant was leaking into my engine while driving. The car began supttering and then blowing thick white smoke our of the exhaust. The car is back home and im trying to diagnose the problem. What could it be? and also is there a way to clean my engine after something line that? or will i need to completely rebuild my engine?

headgasket
when you replace the headgasket or maybe even the head fill your engine up with some cheap oil run till car warms up to operating temp then turn off engine drain oil repeat if you want then refill with some good oil and you should be good

Is there coolant in your oil, or you're just blowing coolant?

its broke new motor time..... well at least new T-Stat, head gasket and check your head for cracks/ warpage. depending on how long you drove it with coolant mixing with the oil you might want to check the main bearings for wear.

while the the head's off replace the timing chain guides and tensioner

There is coolant in the oil. After I felt the car sputtering, I pulled over and checked my coolant (which was low) and my oil which had turned into what looked like a chocolate milkshake and stunk like coolant.

the coolant kills the lubrication properties of the oil, if you drove it for more than a mile or two id go ahead and check the bearings for abnormal wear.

I surely hope you didn't drive it like that and if u did i hope it wasn't for long because then i feel sorry for your Motor i would first check the head gasket and if your knowledgeable tear the motor down check the bearings as stated before. I will speak from personal knowledge i had my fiancé drive my car with a head gasket going out and lets just say the motor is going to need a rebuild sorry for my grammar I've had too much to drink

I"m going to say it's your head gasket. Had the same thing happen to me about 2 months ago and that turned out to be the issue.

Def. the head gasket. I bought a 89 with a 93 motor in it and what you describe is exactly what happened to mine. The oil was like a milkshake, I went ahead and just rebuilt my motor. You dont have to do that, but i would get your head checked. Take it to a machine shop near you and have them do a leak down test as well as a pressure test to make sure theyre arent any cracks or leaks. Id have the head shaved to the minimum too, in the long run this helps because it helps increases your compression and adds a couple horses to the motor. Good luck with the car.
