B8 A4 has crank pulley wobble after rebuild

[Trav__]

Ill try to make this as brief as possible but there's a bit of explanation needed...
I drive a 2010 A4 with the 2.0T engine. A few months ago I put in new connecting rods and pistons from Integrated Engineering after piston 1 blew. Luckily no damage to the block since there were only pieces from around the ringland that fell to the oil pan. I reused the block after cleaning as much as possible, and I never removed the crankshaft. After putting it all back together with a new timing system, I noticed the crank pulley was wobbling. Decided to take it off and try again, and it seemed slightly better but not perfect, and there was a slow drip of oil coming from the front crank seal. This might make some people cringe, but that was the only issue so I decided to drive it through the summer with no other issues. Recently I got it to a dealer to have them put a new pulley and seal in for the leak (pulley was the only part I hadn't replaced the first time around so I assumed that could be the issue). The leak was only worse after that and the pulley still wobbles, and now I'm in a pinch. My assumption now is that the crank is somehow bent or not seated properly, but I'm trying to hold out hope that it's not that serious. It's just strange that there's absolutely nothing else wrong and it runs and sounds great, anyone have some ideas?

I had this happen to me a couple of months ago. took the engine out, replaced timing and a bunch of other shrubbery.

it turns out... i was not diligent enough while meshing the clocking features. It did not clock or seat properly. I had to get a new crank bolt and replace the seal also. But getting the clocking correct got rid of my wobble.

you might need to file down the clocking feature. mine was slightly deformed.

how did it end up going???
I have the same issue, redid the timing and replaced the sprocket from undervest the pulley. Was running straight but ended up wobbling slightly again after all this bull shit. torqued to specs on the bolt, and replaced multiple times.
