If you are referring to inside the motor, good change is it's a sticky lifter. Best option is to add Lucas oil stabalizer and stay up to date on oil changes.

you have antifreeze in your oil. do not drive or you will destroy the engine. most likely you have bad intake gasket. about $700 repair at a shop. about $150 if you can do yourself.

Sounds like you are loosing fuel pressure overnight. Could be a fuel pump problem, or a leaking injector.

as you said the expansion tank is running out of water and the engine oil level is getting higher. Question: does your oil become creamy color or not. If is a creamy color means that the water gets into the oil. Now check whether your engine is fitted with an oil cooler by the engine oil filter. if so possible is that, Is mixing the water with the oil, Replace the oil cooler. If not fitted then the things are getting worse.

Either you do have a cracked compression Gasket or a cracked cylinder head,depends to the water temperature you do have,or the engine behaviour.

Your description sounds very much like a blown head gasket or a cracked head/block. This allows coolant to leaking into the oil sump, causing the overfull indication. Check the oil fill cap. If the underside of it has a "chocolate milk" like residue on it, this is the result of oil and water mixing. If this is the case, STOP USING THE CAR IMMEDIATELY. The water in the oil will cause excessive wear on the engine and destroy it in short order. The engine will need to be torn down, flushed, and the cause of the leak found. Only then can it be reassembled and put back into use.

Is your oil kind of milky looking??.. If I understand correctly, your oil level is much higher than it should be???. If this is so, you probably have a blown head gasket, a cracked head, or a cracked engine block.. It sounds like your coolant is leaking into your crankcase where your oil is.. If I'm on the right track, your problem is a serious one that will require some high-dollar mechanic work... Good luck... I hope I'm wrong..

Go to OB2.com all codes are generic after 1996, doesn't matter the car, if you don't find it here, just google code & number, good luck.
I believe all the B codes are ABS related,

It sounds like your hazard switch needs replacing. The signals are relayed through it. It is an easy fix. Pop off the bezel and unplug the wires and remove the screws that hold it in, than reinstall.

If the battery was replaced you will need the code for the radio to get it working again.

Dirt and dust intrusion into the EVAP canister vent hose assembly, resulting in restricted air flow, may cause this condition.

It sounds as though you are imitating a cold start injector by pouring fuel into intake. I would start there

You'll need to figure out if you are loosing spark or fuel when it fails to start up to know which system to test.
