Checking Timing Marks - A4

[Bhatti, Mohammed]

Sorry folks, more questions:
 
Ok, so what if after I've removed the t-belt and somehow, screwed up by moving the crank and /or cam shaft so that now the timing marks are out of alignment.
 
Can I simply line up the crank pully to TDC and same with the cam?  And what's the deal with turning the engine 2 revs clockwise?  Is that to just make sure that the valves are not hitting the head and can I do it with the belts off?
 
Also, according the Bentley I should replace the crank bolt if I remove to change the seal.  I ordered the crank bolt but it'll take about a week to order.  I'd like to get my car back on the road this weekend so I'm thinking of skipping the replacement of the crank seal.  Bad move or should I wait a week?  Thoughts?
 
Thanks again.
