If you're planning to dig into this yourself and you don't have one yet you owe it to yourself to get a Bentley service manual... all the right pictures, all the right step-by-step instructions for anything you'll ever want to do with your car.

As for the manual I do have a HAYNES repair manual, how do these own up to the bentleys?

Kids these days would probably say Bentley >>>>>>>>>>>>>>>>> Haynes.   ;)

Meaning, the Bentley is the official service manual and covers off much much much more detail.

Having said that, the Haynes will probably get you where you want to go... just with more head-scratching and googling.

 Ah yes, my haynes manual does make my head quite itchy and lets me excersise my google-ing, but for the most part it has helped me get the work done.
If i was looking to get a bentley what would the best way to get ahold of one be?

Chapters has em for 46 bucks... the Coles/Chapters/Indigo in the Skenna mall could probably order it in for you, or you could have Chapters send it to you directly.

Same 46 bucks from Amazon.ca

I forgot to ask, When i was rotating the wheel to turn the crank to TDC it got really hard and i had to put some good juice into it, keep in mind this was on the compression stroke for cylinder 1. Is the normall or is it indicating valve contact/damage

Did you force your way through the extra resistance?

If you waited did the resistance go away slowly (as the compression escaped)

In my opinion your next course of action is to find out if someone local to you can do an in car crank nose repair. If there is then talk to them and ask them what the prices will be if you do all the prep work or if you let them do it.

If you can't find someone local to do it in car your next course of action will be to pull the engine. You will need to pull the crank out and send it to a machine shop along with the TDI crank gear so they can make it fit. You could remove the crank in the car but I'm fairly confident in saying it would be much easier overall to do with the engine out.

The Haynes is good for lighting a fire with so you can read the Bentley :) Actually I like having both because sometimes the wiring diagrams in the Bentley can be confusing but the Haynes clears it up.

Now is the time to do the timing belt and tensioner if there is any doubt in your mind as to when it was last done.

It was sort of forced but there was a release of pressure after it passed so im guessing it was just the compression holding me back.

You might want to look into doing a leak down test if you have the equipment. NOT a compression test.

What is the leak down test going to tell me. I know it measures how fast the cyclinder looses its pressure. Will it tell me anything about the valves?

Yes it will tell you how bad and which ones are bent. It will give you an idea on how expensive this repair is going to be. If you find that you have a valve leaking you can remove the cam and tap the lifter with a piece of wood and hammer. You might be able to get it to re-seat if it's just carbon build up or something to that effect.

alright, going to have to wait till guesday to do this unfortunatley since the dealer is closed until then, and i am not aware of anyone who has the tools to do this. Unless there is an easy "hardware store" way for me to do this?
If it turns out it is a bent or numerous bent valves what should I get replaced while I have the thing apart? All the valves, lifters, or just the bent ones? Should I get the head re-surfaced by a machine shop also?

Finally got around to taking the serpentine belt off of the crank and found that the pulley has tons of play in it. Im guessing now I have found that the Crank Sprocket is 100% the cause of all my problems.

Am I correct in stating this?

That is pretty much the definition of time bomb. If you haven't already searched for the aaz crank sproket fails please do as you won't want that to happen :D
