Re: cam lobe wear
If that cam lobe is worn like that , I'd swap out that cam . You can get regrinds for lower torque bands pretty cheap , be a good time to upgrade it . Yes, the cam has to come out from the rear of the head . Check the bearing surfaces of the journals , they have to be very smooth and no wear inside the head since there is no real bearing , the head has no real tolerance for wear either . If oil changes were that far apart , you may want to consider rebuilding the head you have and use it instead . When you do re-install that cam , stake those locking screws that go into the rocker shafts real well , they have a habit of backing themselves out and losing oil pressure . All of those 6mm bolts can be easily helicoiled , I just get a kit with a large refill of coils and do any that are worn when I go through a block . Cheap enough and keeps all the original bolt sizes correct , makes it a lot easier to work on later .
