I do have a 2 post lift in the garage so either is possible but I prefer not to pull the motor unless I have to do more such as crank bearings.(hoping not to go that deep as its not burning a drop of oil yet between changes.
Has anyone ever heard of having to change the balance shaft chain, or do you think its safe to leave as is.
I hope things are going smoothly as you are doing this to your HHR. This seems like a pretty touchy project. I wish you the best as you do the change. I look forward to any updates or pictures you would like to share.
