Yeah I might have to yank the valve cover and replace the two lift bolts..I have two new ones from monkey wrench racing that I have been too lazy to install. Is it hard to install them? Or is it just a matter of knowing the torque spec for the lift bolts? Thanks in advance!:bow:
Difficulty could be variable. The bolts are there to lock the positions of the hollow rocker arm shafts so the oil ports will line up properly. The lift bolts should be torqued to 66 in-lb. If they break, the shaft(s) can get misaligned. This picture shows the proper alignment (you can just see the slots in the end of the shafts):

If a lift bolt is broken, it can be hard to extract both pieces. Also, re-aligning the rocker arm shaft could be tricky, because the camshaft gears are in the way:

If needed, you can gain access to the shafts at the other end of the head by removing the VVL housing. (By the way, the thing sticking out of the housing to the left is the control valve that Sturgeon mentioned).

Three bolts and two nuts (80 in-lb.) are removed to take off the housing and you can see the other end of the long bores that the rocker arm shafts are in.

The valve cover bolts and nuts for the vent pipe get 7 ft-lb.
If the lift bolts are not the cause of the problem, you can test the oil control valve for proper operation. I'd also get a good look at the wiring going to that valve.
