Subaru Valve Train Help
I posted over on the Subaru boards. I didn't get any real answers. I'm hoping you guys can help me.
I have a 1991 Loyale,SPFI OHC ea82 engine that lost its valve keeper on #3 cyl. intake valve while the car was underway. No apparent damage to the valve train and the motor is non-interfearence. Cyl. walls and piston are in good shape.
I want to replace two rockers,the #3 cyl. intake valve and the assosiated keepers and springs. I want to retain the original cam as its in very fine shape too.
My question is,can I put diffrent rockers,new or used, on the existing cam without damaging the cam?
I can see where the valve tip is buggered where the keeper use to rest in the valve tip shoulders,so,of course I will replace the valve. But,I'd like to replace the associated components as well.springs,rockers and keepers and such.But not the cam. My concern is,I shouldn't put new or diffrent rockers on a old cam. It may ruin the cam. Is this true?
Any ideas or thoughts appreciated.
This is what I found in the bottom of the cam tower when I took the valve cover off. The keeper simply let go.

You can put new rockers on, and replace your HLAs, since that is a common sign they are about done. Do you have any TOD problems? A bad oil pump seal or even a worn oil pump can cause both of these issues.
Did you post this on USMB? I was over there at lunch, but didn't see it. I've been cruising the classifieds and retrofit forums due to my EJ swap, so I could have easily missed a post in the Old Gen forum.
