    The removal procedure assumes that everything is out of the way of the cam cover - hoses, belts, pulleys, belt tensioner, everything.

    As posted, you'll have to remove (and replace) the camshaft seal.

    How do I "work" the valve cover off

    Valve covers wedged on there do I have to jack the front side of the motor??!?

    Is everything - EVERYTHING - out of the way ? All hoses, radiator cover, belt tensioner, w/p belt, cover, everything.

    No, you should not need to lift the engine - and if you do, you'll need jackstands to hold the car and then remove the front motor mount.

    Re: Special tool for Northstar water pump drive pulley

    I can lift the cover all the way off on the one side (over the chain on the inside and everything) then when I go to slide it off the rod the covers not moving at all

    Have you removed the cam extension oil seal as shown in Post #14 ?

    Buy a new one for the replacement process. The original WILL leak like a sieve.

    Re: Special tool for Northstar water pump drive pulley

    It takes the removing of the bolted on cam seal to gain enough clearance to work it off the end of the camshaft "That rod"

    Re: Special tool for Northstar water pump drive pulley

    He did that since Post #14 and #17, verified in #22

    Can you work the cover back into its original as-installed location and begin again with the oil seal removed ?

    Re: Special tool for Northstar water pump drive pulley

    I see where you told him but didn't see any response where he did it. All he can talk about is having his head unbolted and that darn "rod"
    I think he needs to bolt his head back on so he can think and do as suggested and remove the cover.

    Re: Special tool for Northstar water pump drive pulley

    If the cam cover is off how about - Is the belt tensioner for the water pump still in place? Did you get the valve cover bolt that's hidden on that side? Is it getting stuck on the oil dipstick or upper radiator hose? Those are the initial items in that area that come to mind that you might be fighting against.

    Thanks for the reply I have everything out of the way the cover seems to get wedged by something under it on the right side near where I took the pully off when I lift the left side over the chain then I can't slide it

    Have you tried rolling the engine over a little. you may have a cam lobe interfering with it.
