ive changed vc gasket an gromments an put some leak stopper **** doesnt seem to work i just replaced those gaskets went up the road to find oil back in there motor is a ls stock head an block its got 120xxx idontknow where else oil could be getting in

 

The oil is leaking into the spark plug tubes from the lower rocker tube seals. The rocker assembly will need to be removed. I would recommend using a service manual to ensure proper sequence of removal/installation and torque procedures are performed.
