Hi,
So I did a timing belt, crank seal, and oil pan reseal last weekend.
Went under the car and checked for leaks, and sure enough found oil dripping from timing belt area.
I took balancer off and ran the engine and verified that the crank seal is leaking.
I did not use official vw tool for seal install, I used the old seal plus the crank bolt and pushed it in carefully. Of course, I used the plastic cup they provided in the box to slip the seal onto the crank.
Interesting note, on the the seal's box there is a picture showing to turn the seal 3 hours clockwise. Can anyone clarify on this?
Here are the youtube videos:
http://youtu.be/11INjfTjhbA -Crank sprocket
http://youtu.be/4BYN5aeoCAw -harmonic balancer before TB change.
I will make new one after TB change. But need to replace crank seal again. So I make new one after 2nd seal change.
When should the balancer be replaced by the way?
Now, I dont see much vibration in the tensioner, so I dont want to spend $ on a new balancer and just keep driving.
170k miles on engine and chassis.
The only thing Ive noticed is the sprocket clockwise to counterclockwise "slack" on the D shaped crank. I would estimate a little less than 1mm either way. But, crank looked in perfect condition. Only noticed the sprocket had some minor wear towards the ends of the flat.
As far as the wobble is concerned. I am thinking the crank bolt is not perfectly true, thus the visual illusion the whole sprocket is not true. But I made a mark on the aluminum and turned crank by hand, and all the teeth fit right under the mark the same.
Please, share your thoughts. I appreciate it.
Thank you,
Kristof
