Default Internal engine gurus please step inside !

I finally found out the cause of the clicking in my engine . I took the pass. valve cover off and found #6 rocker extremely loose . I took it off and inspected it and it hasnt lost any bearings , so I looked at the pushrod next . It was so very slightlybent , and the only way you could tell was on a piece of glass . This surely couldn't be the culprit , so I put the pushrod back on the lifter and pushed down on it to see if I could get the lifter to budge and it wouldnt move. Usually you can get them to move very slightly . All of this checking leads me to believe the lifter is collapsed . My question is , if I take it apart and find it grenaded , then most likely it has sent metal throughout the motor . If I do find it to be this way , my best bet would be to rebuild the motor wouldnt it ? I want to repair it correctly , so I wont have to do this but one time . Any insight will be much appreciated .

Thanks guys !


Joe

Ok , Looks like the worst case senario has arrived . I also found some scoring on the cylinder wall on # 6 . The lifter must be granaded bad , as it will not come all the way out of the block . Looks like it rebuild time fellas .

Just because the liter doesnt push in, doesnt mean its collapsed. When the lifters are pumped up (full of oil) they will not push doen with your hand. I thought this same thing so I bought a second set of lifters and I took the old ones apart and there was nothing wrong with them.

Your next step should be to check out your oil pan, see if there are any lifter bearing fragments in there.
