Advice on next step after timing belt failure

[Aferrell71]

I have an 04 A4 1.8T Quattro and after fuel pump replacement and filter, plugs and crankshaft sensor replacement the timing belt isn't turning. I checked when I first started down the path of the car not starting, the timing belt was turning but I am wondering now if it hadn't jumped timing or sheered a couple of teeth which caused the issues from the start and now after trying to start it, it is now just not turning at all.

So do I go ahead and spend the money to buy a timing belt kit and a rebuilt head and do it myself? Or do I get rid of it? I cant afford to pay a shop to fix it, that's over $3000 worth of work from what I understand.

Options? Thoughts? Suggestions?

You had the crankshaft replaced?

Sorry left out the sensor part lol Crankshaft sensor

First step would be to try and turn the engine over by hand. If it turns over line up timing marks and verify timing.

What is the best way to do that?

Take a 19mm wrench and turn the engine over by the crank pulley. You can get in from underneath, it's a little tricky sliding the socket in past the service carrier but it is definitely possible. Once you get it on the bolt rotate it clockwise. It will be a little difficult to turn since you will be fighting compression but if you are putting alot of force and it still wont budge then most likely the valves are coming in contact with the pistons and in that case you will at the very minimum need a rebuilt or replacement head.

Thank you, I will try that and see what happens. If it did bend the valves, most likely will just be a head replacement? Or whole motor?

Just a head replacement. Unless you broke a valve that dug a super deep mark in the cylinder walls. Thats doubtful. Usually the valve stems bend and thats the extent of the damage.

If you remove the spark plugs first it will be much easier to turn over by hand
