Hello I am currently reassembling my 4.0l sohc after installing new chains and guides I went to install the new passenger side camshaft sprocket and my new sprocket messed up my camshaft beyond reuse my question is can i install a new camshaft with out any problems with my old bearings?

 

Tough call, if no bearings show unusual wear pattern then it would probably be OK.
But I would price out new bearings just to see what extra cost would be, so you have a "risk/reward" price point.

Many upgrade cams on OHV engines for more power and never change the cam bearings and never have problems, so outside of an obvious wear issue it should be fine.

 

bearings showed no obvious wear whats strange to me tho is that there is no bronze bearings my cam just sits directly on the part of the head that the cam bolts to with the caps.

In order for me to get new bearings i would need a new head and caps.

 

If it runs right on the head (aluminum I'm assuming), what they do is take a bit of the caps where they meet the head.
After that it's line bored back to spec.

If you really want to get fussy you can use some plastigauge, although I'm not sure what the factory clearances should be or if the spec is in the manual.

yes I do have aluminum heads.

I believe i will be ok. cam and bearings show no bad wear at all and whole engine is spotless inside. thank you for the information
