How would you fix a 93 Ford Escort 1.8 LX that is getting air to only 3 cylinders and unburnt fuel is turning the exhaust convertor red hot?

Because you are pumping unburned fuel/air mix into the convertor and it is igniting inside, creating intense heat and the red glow.

On quite a few older 2 stroke jet ski's, water is injected into the exhuast flow to cool the exhaust pipe, and possible turn the pipe. If the moter stops running and you turn the ski over the wrong way this water can enter the cylinders. Once in the cylinders it can damage the pistons and rings. If the ski is running this is not a problem because the exhaust gasses keep the water from entering the cylinders. If the ski is not running there isn't anything to keep the water from entering the cylinders if the ski is rolled the wrong way.

theres a very good chance that the engine has a blown head gasket. what is happening is the water cooling the engine is escaping past the head gasket & into the engine, mixing with the oil making it milky coloured. the water is also escaping into the cylinders, making the steam come from your exhaust, you may also have trouble when turning the engine over, with water building up in the cylinders when cooling down.

White smoke in the exhaust is water leaking into a piston and turning into steam. You have a leak somewhere in your engine. Your engine may overheat because you are low on coolant. You have run it out through your exhaust pipe. Soon your engine will catch fire and burn up, but you will have saved money by not getting it fixed.
