    cam plugs

    On my ski the rear cam plug on the intake side popped out at wide open throttle and lost all my oil pressure, It took out my supercharger bushings and shaft because the lack of oil to the supercharger. When i was doing the big bore i was going to replace the freeze plug with a new one but noticed the front one had also moved and ready to come out. Let me tell you they are not that tight in the cams so what i did is take a 1/4 NPT tap and tap the cams and put threaded plugs i will never need to worry about them again. Because losing oil pressure at WOT is very dangerous to your motor.

    I would not do this in the ski the cams need to be out, Once they are tap you can clean thru the cams so it can be cleaned out so there is no metal inside.

    Hello Jorge take a punch and small hammer tap on the side of the plug inward and the opposite side will pop out. So basically what happens is the plug turns in it's bore. Or drill the center of plug get a long sheet metal screw and screw it in, then grab the screw with a vise grip and tap on the vice grip out with the hammer and it will pop the plug out.

    Spot welds works good too

    do ALL 1.8L S/C engines have this problem, stock and modified?
    Will this be another MUST DO on the FZ machine like the intake grate for bucking issue?

    I have seen it on modded ski's but don't know if anyone has had this issue with stock, Maybe people can chime in if they had any issue with stock.
