Need some help on my new to me SLK 320
 

Hello all,
This is my first post and I hate to introduce myself like this but, I have a problem. I recently purchased my first MB. It's a 2001 SLK 320, 6 speed, 100k miles. The car seemed to run and drive alright. Drove around for about 30 minutes no issues. Two weeks later agreed on a price and went from central NC to Va to pick it up. Drove back around 140 miles, no problems. The car has had a history of leaking coolant at the expansion tank. The previous owner replaced the expansion tank and thermostat prior to me purchasing the car. When I arrived home my son went for a 5-10 minute spirited drive and came back home and had blowed the coolant from the tank. I let the car cool and refilled the tank, everything seemed fine. The next day I went for a drive and about 5 miles into it the car developed a miss and the CEL came on. Four of six clynders were fouled from coolant. I replaced the plugs and now the car runs fine except for the billowing white smoke and the sweet smell of coolant being burned. I have to assume that I have two blown headgaskets. Is there any other way for coolant to enter the combustion chamber? Sorry for the long post. Thanks in advance for the help,
Randy

Sure sounds like a head gasket.
A good shop should be able to do a chemical block check to see if that is correct.

The whole circumstances seem odd to me. To blow both head gaskets at the same time. What exactly is a chemical block? Is there anywhere in the intake/throttle body that can pull in coolant?

Chemical block test is a check for exhaust products in the coolant.

That is what it sounds like to me too.

Before you get into costly engine repair consider looking for a good, used engine. I am of the opinion that if you can find the right engine you will come out money ahead.

You may be able to get the PO to take the car back under the law.
