i had a small drip from the cam cover by the turbo that dripped on the exhaust manifold and burned.. soi took the cam cover off and whatnot and put some sealant on it and reinstalled everything.. i go to start the car and now it wont start..i took the cam position sensor out also to see if the o ring was good. checked it to make sure it was aligned numerous times and now all the car does it turn over with nothing.. im getting aggravated? any ideas?
