Lucky I took car in for work today

Grawil, I wrote 'MrVermin said' and in the next sentence I used the word allegidly. I did not state it as fact. But you are right (I can't beleive I just wrote that), I should have chosen my words more carefully.

I said it before and I will say it again, I agree that the damage was clearly caused by the removal of the sprocket and that the OP did a poor job of explaining that. Thats is why I chimed in with my observations of the sprocket at the GTG. No high res pic is going to change anyones opinion that the damage was caused during removal. The pictures were graphic in nature and should have been posted with more info. (ie: Mechanic B said that the sprocket was on so tight, it broke during the removal).

I also don't agree with the OP naming names so soon. But what can I do about it now? If I delete this whole thread, some people are going to say that I am protecting the OP, others are going to say I am protecting the original tech to save his name. I can't win either way. What I should do is merge the 2 threads together in the TDI 101 forum and let another moderator with no connection to either parties take control.

If you toss out the busted cam sprocket, you are left with a few worn lifters after a year of driving on a high-milage engine. It is hard to attribute failure to a faulty install after a year. As you said before, many possibilities.I want to see photos of the lifters and see measurements of the lifters/cam. Would be nice if VDUB TECH can comment on the source he used for the lifters and mrvermin on the oil/additives he used. I hope wroth took a very good look at that cam/head before they sent mrvermin on his way...

Metal nerd makes a great puller for the alh motor .(Yes there tools work so good that no damage can be done)just sayin.Overtightened sprockets/ bolts is a mechanics daily routine,happens all the time.I've never seen a sprocket like that before whether too tight or way too tight it just doesn't happen.Maybe it was overtightened , a phone call could have corrected it, plain and simple.A little too tight is always better than a little too loose.I also have digital/audio/illuminated trq wrenches made in USA and use them on a daily basis.If I made a mistake or my helper, I most definately make it right, always have and always will.If humans didn't make mistakes how would they learn?

While i agree the metalnerd puller is badass, it does not protect from stupidity. I could see the sprocket being cracked by someone failing to loosen the cam bolt a few turns first, or even possibly an impact wrench on the puller. Either way its removal damage in my opinion.
