started something over at benzworld forums but was sent here . heres what i have so far http://www.benzworld.org/forums/w140-s-class/1381467-97-s420-no-power-petal-floor-knocking.html

today i recieved word from the dealer saying that they need to tear down the whole engine and find the cause of cylinder 4 having no compression. also they said cylinder 4 not having any compression caused the other 3 cylinders on the passenger side bank to have a missfire which makes no sence. im pickin up the car from the dealer in the morning to start tearing it down myself hopefully you guys can help me figure out the cause. also i changed the oil and there was no metal shavings or even flakes so i doubt its a rod knock. any ideas would be greatly appriciated due to me getting stuck with this 5700$ car that doesnt run and i cant drive it.

Thanks
