Yes all those parts listed have been put in but the brand new timing chain is still off a tooth and will not line up no one can figure it out, what the hell is wrong with it...
The old chain became so slack it may very well have jumped a tooth. Just reline up the dots and install the chain. To move the cam around a tad, take the pressure of the cam via the loosing of the rocker arms. Remove the spark plugs to turn crank quicker and with ease.
On the parts replacement. I have had a few cars like that. Once you iron out the bugs, you'll be fine. It is allways the case.
