the car jerks when putting car in reverse either from park or neutral, I wonder if this is something I have to be concerned about.Car has 120k miles it also has a leak which is not muchi don't even have to top off at times. But just wonderingif this is coming from the mainseal oroil pain or the head gasket, If ever its the head gasket is this somethingdifficult to do. I havechanged breaks, oil change, shocks and serpentine belt so I'm not sure how much work this involves.This is my first post, this forum has been a great help. Thnks again in advance

 

jerks as in.. moves backwards a little?
It is a bad jerk?
Mine does that too, but not bad.. I think its just a Camaro thing. I can have mine in D or OD with the brakes on at a stop, pop it in neutral and the rear end will drop just a little..

 

yes it moves backward a little.
