Had a problem an engine problem when driving a 2006 CLS 55. Did a couple runs over 130 mph last week and during last run at close to 140 mph felt gas pedal shut down lost power and immediately the check engine light came on, also started smoking immediately. Pulled over right away and turned the car off and started it again to try and clear codes. Car was shaking very bad during idle. When right home opened the hood and found oil cap seal blew and oil was all over the engine. Took the car to the mechanic over the weekend. They did a compression test yesterday and said the problem is a blown piston. Mechanic said that rebuilding the motor is not and good idea since they are hand crafted by amg and didn't want to take a chance. Also after talking to several other mechanic's and reading other posts online, it sounds like replacing the engine is the best solution. I would appreciate any imput from other members to help me in finding a good engine at a responsible price. I already checked ebay but only saw 1 amg 55 engine with 94k on it. Any additional imput would be helpful.

Thanks

The car was just purchased about 6-7 weeks and I think it had a stage 2 kit for the supercharger, which changes the pulley and reprograms ecu.

I was thinking this may have caused the problem. What do you think?

Def a contributing factor. Any idea on which tuner was used?

Not sure what kind of tuner it had. Trying to do some more research to find out more info.
