my valve cover bolts keep getting loose. Does anyone know why? I tighten them a couple of months ago to the factory specs, but no dice. I probably should replace my gasket, since oil is leaking slowly. Not sure if its the gasket or the bolts, anyways, ive got 201K on the motor....maybe i should be complaining

 

and what engine is this on?

 

my fault...its the 5vze

 

Put blue locktite on the them and it wont happen again.

 

i have a torque wrench and loctite. I will be home all day
