Hi members
Happy New Year
My skyline has no power. It's a straight line 6 cylinders non turbo engine. The first 5 cylinders have low compression. The fifth one is just 10 psi. The sixth one is ok. No slippage of the timing belt. I have removed all necessary bolts to remove the head except 3 allen type bolts on the engine head. The allen bolt heads seem rusted as these bolts are out of the rocker area in between the two cams and not exposed to the engine oil. They are very stubborn and one of them got stripped out.
I request the members to guide me to undo the bolts. Will using the extractor method work? If no, can I weld a nut to the bolt to ease the job?
Please answer.
