When replacing the timing chain, is the passenger cam supposed to be free or not? I placed the engine at tdc but right side cam is not free, if I remove the chain it will skip for sure.

There is a link to a 2006 FSM in my "In deep with airbag light" thread.

Perhaps it will help.

I have the fsm but it just mentions the cam psition and marks. It does not say if the right cam is free like the left one. I know it is at tdc but I find it strange that the right cam is not free to remove an replace the chain. If that was the case then I would need somebody to move the cam into position and hold it while I install the chain.

By free I mean I have all valves closed on the left but on the right side the cam is holding valves open so it will skip as soon as I remove the chain.

Somewhere between being sane and insane!

At TDC 2 cylinders will have both valves closed,2 will have the intake valves open(exhaust closed),and the last 2 will have the exhaust valves open(intake closed).

That is correct. You'll need to hold the cam in position to take the chain off.

Other option is to remove the cam sprocket and let the cam turn, replace the chain on the sprocket, then rotate the cam back to position. Not sure how difficult that would be since you'll be compressing some of the valve springs but that is an option.

That's what I did... Everything seems fine, all dots aligned... I had to go the hillbilly way by holding the cam with a large locking plier (I used the spot where the special tool goes). Let's see if it starts... LOL...
