White smoke and the color of the oil definitely looks like a blown head gasket or cracked head/block. When you pull out the oil dip stick, does it look like clean oil at the tip and a milky residue at the top?

Yup, take that head off and pray that its a blown head gasket. Anything else would be absolutely terrible.

That's jumping the gun a little. He's got mixing fluids AND intake issues, the car should be running like poop. Assuming the MAF code is unrelated to the health of the motor, a blown headgasket OR cracked block are possible. In the case of the block being cracked, yes it is a ripoff, but as long as the motor hasn't been overheated allowing the head and block to warp, a new gasket should fix it. Take the head off. turn it upside down and lay a straight metal bar across it in a diagonal fashion, if its flat, GOOD, if not, warped head. Another way to find warping is if the first test checks out and you replace the gasket, and it blows not too long after in a spontaneous manner, that's an indicator of warping as well.

As for the circuit malfunction, check the connections at the sensor and if they check out, follow them back to the ECU.

Malfunctioning intake readings will cause issues with getting AFRs right, and getting antifreeze in the combustion chamber will cause a problem if there is enough of it.

Do a compression test to narrow down what cylinder your having problems with. Doubt it.s the block being cracked since it.s iron, it.s either the head or the head gasket.

You have 2 tech posts on this site, DO NOT add your opinion of helping when EVEN THE OP which is me, knows better than to believe my block is cracked or warped. Lmao. i figured it was a HG or my head! ill check it out and let you know!

If you find the head gasket to be bad then its a matter of tearing it all down, but if its something minor meaning no head removal consider flushing your engine with lots of oil, a good tip is to add seafoam to your oil because it will help carry the contaminants to the filter and clean your oil gallies.

I see lots of water or coolant in your oil but is there oil in your cooling system?.

Any luck with finding out what.s the problem?

No, waiting on head gasket to arrive.
