attach the new chain to the old chain and pull it through...
you dont have to hold the cams, but you need to ensure the crank is lined up at "0"...and that the arrows on the cams are lined up PERFECTLY or your timing will be off, I still think mine is off but I think its w/in the tolerances for the ECU to correct for.
and ya i used the breaker tool to push the pins back together and used the bolt cutter to actually break it

Do I need to take the airbox and intake manifold off If i'm just changing out the chain and guide rails? I hoping to keep this easy and less steps

MBWorld Fanatic!
But AFAIK if your chain skipped and you need to pull the head, then you'll have a good time

This is interesting stuff! Apparently you tension ALL the valve cover bolts, including the ignition coil bolts 0_o
