• I pulled this motor apart yesterday and figured y'all would like to see what happens when a valve head decides to end it's relationship with the valve stem. This was an AAZ engine.

• a bad injector is my guess. my grandpa has this happen to him all the time. he is on his fifth engine now. ive bought one engine that had a valve head sticking up sideways in the top of the piston.

• Or that valve hit something earlier in life, and was weakened.

• This is exactly what happened to my ALH engine, dropped cyl. 4 intake valve.

• Hey,  why don't you knock those pre-cups out of the head and get some pics and measurements and post them up.
  
  Then sell them to me  .

• Yeah it was a clean engine. I think the block is savable.
  
  The precups all have cracks in them. I had thought of knocking them out.
  
  I think the crank gear started to slip and this valve decided that the abuse from the piston warranted it the right to defect from a functioning society.

• Lil JBWELD and that piston will be fine.  Run it.
