• Problems removing cam followers. by Barry W on 17 Jun, 2007 22:24
• I got my head back from a shop that was going to rebuild it. They told me they have never seen cam followers get "mushroomed" like these ones are.
  Now the story on this head is it was on my car that lost a timing belt. The bottom of the head and valves look fine but the cam followers will not even move. Although I was able to remove only 2 of them.
  
  This a common problem?
  
  Anyways I am told the head is garbage because the followers can not be removed.
  On to the pics.

• Just weld bolts onto them. Then you will be able to apply some force. :twisted:

• I suspect that even if you could get the cam followers out, the bores for them would be shot.  If you put it together new cam followers, and they stuck while driveing, the result would be that you maybe could use the starter, and alternater on the next motor.  Everthing else would be junk befor you could turn the key off.

  I agree, even if you get those out, the head is still toast....................

• i would say that the head isn't junk... but the cost of repairing it might make it easier to just buy a new one...

• Interesting, how do you repair cam follower bores that are out of round, may have chunks of metal missing, and will have deep scratches when extremely distorted valve lash discs and cam followers are forcably removed?

• I wonder if you couldn't rebore and sleeve them? Still might be cheaper to buy a new head though, but it wouldn't hurt to ask.
