Was tearing down a 96 STS block and noticed what looked to me to be some excessive wear on the primary timing chain sprocket bearing, and intermediate shaft.
Tell me what you guys think. I found the sprocket on rockauto but can't find the intermediate shaft.
The sprocket from rockauto I would assume has the bearing already in it?
Also can I reuse the oil distribution plate/gasket. I can't seem to find replacement for that either. The bottom picture will be the dist. plate. Not to sure on that item.
I took one of my cams off and noticed too that the cam had left a dent in a couple of lifters. Possibly when the motor sat with the cam lobe point right on the lifter.
My question is if I can see and slightly feel the indentation they need to be replaced correct?
I think that's it for right now on the questions If any others arise then Ill prolly have to make a whole new topic.
You can see here how on one side the end is all grooved up.
And then here you can see the back of the shaft is grooved up but now the front is smooth.
Then you can see here where it fades in on one side and fades out on the other.
