So im doing a lower end rebuild on a 4.2l, I forgot how it goes back together...

So im doing a lower end rebuild on a 4.2l, i for got how it gose back together... im mostly wondering about the cam... theres that bolt with the spring and pin that bolts to the cam shaft, is there a replacement part for that bolt? and is there sapost to be a washer or something on that? i think the pin and or spring may be worn out theres evidence of the cam trying to pop out... unless im missing somthing i never took the cam out just the timing gears and crank but that was last year and i forgot how it went...

The pin lightly pushes against the timing chain cover. You need the washer in the photo too - there might be small grooves in the washer - or maybe its in the cam sproket, don't remember. But unless you really cleaned everything there should be markings on the backside of the cam washer. It needs to go against the sproket.
