Title: Carnage
Post by: burn_your_money on May 24, 2010, 01:13:25 pm

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,  :D 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  ;) ;D.

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.
