    Not all adjustable push rods are the EZ install type. I still need to remove my rocker arms to get my adjustable Andrews p.r.'s out. It took me a while to remember that when I was putting new lifters in last month.

    This is going to sound stupid...but TDC...means the pushrod should be at the very bottom of it travel...correct? That Is how i have been doing it....thanks

    As mentioned above, if you at TDC of the compression stroke, there should be no valve spring load on the pushrods. They should rotate easily with your thumb and finger. Screw in the pushrod adjuster all the way, and the pushrod should come out. You have to push the rod UP into the rocker arm socket and then the other end of the pushrod should clear the lifter block. If none of this works, those pushrods may not have been for that engine and were just available. If this is true, I would cut those out and replace them with adjustables for that engine. I would not disturb the rocker boxes just to replace pushrods.

    TQ

    I had the same problem. It was recommended to remove the tappet block, pushrods, and tubes all at once. Much easier than opening up the rocker boxes.:)

    Sorry, I was working on 2001 TC. Tappet block is really just a cover and no need for aligment. Just saw this post is about 1990. Not sure this idea would work, even with the alignment screws.:(
