I also made a big mistake and when working on correcting the problem, I swapped number one spark plug wire, with two spark plug wire.... the car is better than ever.. I cant believe it. I almost sold it next to nothing. And or spent all that money on a new motor... I love this car and I am currently working to save enough money to get the oil leaks taken care of... once again you have all come through with your know how.. i am grateful to you all for your help. The cost of repairs was $50.00 and 6 new park plugs. I found a great honorable Tech that helped me do the work and correct the car.

Good work!

What about the oil and water mixing?

Either the oil is in the water or the water is in the oil.
Neither is a good for your engine.

If you are getting oil in the water, then in addition to the head gasket, you've got a huge mess in the cooling system. I've got a 94 E320 parts car with this problem, and the radiator shop has been trying to clean just the radiator, so I can use it on my cabriolet, and they are still getting oil coming out of the rad after two hot tank sessions. The oil also will cause all your hoses to eventually fail, and if it's this hard getting the radiator clean, I'd hate to think about the heater core....

If you are getting water in the oil, then all your bearing surfaces and critical lube points (think cam lobes) are not getting lubrication and are getting wiped out as you continue to drive the car...

Driving with this problem will quickly ruin your car.
