So, I picked up a parts car with a "blown" engine for next to nothing. I started stripping the engine and sure enough found the secondary tensioner on right side was bad and secondary timing chain broken. I decided to keep going and took the cylinder head off. What happens when the secondary tensioner fails? The picture below shows the damage done...bent exhaust valves that gouged into the cylinder head itself...ouch.
Congrats on saving another one! I would bet the previous owner would kick himself if he knew........
Question:
The valves typically bend or snap off from contact with the piston face. Were there no signs of piston damage on this engine?
You could see the carbon build up worn off the piston where it hit the valves, but amazingly there was no gouging into the piston like there was into the head and the piston was not cracked...got lucky I guess.
