on the t-chain on the 560. Very helpful. I also bought the Benz CD with the shop manuals - first purchase I did after buying the car.

I figured it might also be a good idea to remove the plugs - makes the engine easier to turn with no compression.

When removing the rockers - Benz recommends this hugely expensive valve spring compressor to get the rockers out. Will a simple screw-type compressor do, or am I going to have to spend the $175 and get the tool from Samstag sales?
