how do you know your not getting oil to one side or the other without pulling the valve covers???

need a year of the truck to determine what all they got on that motor. throttle position sensor might cause surging and whatnot, but then again...


as for the smoking, you might be burning a bit of water...

:chug:

 

i took out the oil filler cap an the head is bone dry an after about 5 mins the right side head starts ticking louder an louder till the surging kills the motor
