I am almost done with the 03 cam mod in my 426 and with help of another TT member I was told about the cam chain tensioner. I completly removed mine from the engine when I did the mod. What do I need to do to get it back together right. I did searches and found little bits but nothing solid. Is it supposed to move in and out if you press on it for supposed to be tight?????????? Please help quick as I'm off to the dealership right now to get my shims. Thanks.
