Just finished my first head gasket!!! What are these vibrations?

[gieri002]

I just finished my head gasket install, I started the car to make sure all was OK since I replaced the water pump, timing belt, and just about everything else while I was in there. Well the car started right up and seems to run good, BUT it vibrates really bad, the vibrations get worse the higher the rpm goes. I still have my jack on the oil pan and the drivers side motor mount is not put back on yet since I don't want to put everything back together and take it back apart when something doesn't work out.

Well could this be the problem, or is something up with my balance shaft or something, I never touched the balance shaft belt because it was already brand new though. WTF

I would have changed the B.S belt no matter how many miles is on it. A new oem is only like $25.00-+. They seem to wear quicker than the cam belt. Thats just my 2 cents.

Ya, I just put on a new balance shaft belt for the h### of it. It only costed like 19 bux so I figured why not since i'm taking it apart again. Thanks for all the help though!
