This is an important post everyone should read....

Here is the result of a miss timed Interfearnace engine.

Timing on the right head was off by 3 or 4 links and this was the result.

These are the valves after disasembly of motor


This is one of the cylinder heads


This is the Two cylinder heads and the broken valves, notice damage to heads where valves were crushed.


This is of the two piston heads that were damaged as a result of the mis-timing.


Wanted to post so everyone realized the seriousness of the timing settings on your motors.

Anyone have a handle on a 5.4 for my bird? or a PI Explorer motor, I'm all ears...

did you try and turn the motor by hand once you reassembled it? With it being that far off you should have been able to tell with turning it over by hand before you started it...just so you know for next time

No, unfortunately I did not. I did not know what I was doing. I should have looked into the process more. What I learned from this experience I will never forget.

yeah you have to really turn your engine over ALOT to test it... And it sux when you have to do it with a break over bar. I'm sorry you had to go through with that. When I did my PI cam swap we marked with a magic marker the little pins in the links. One of the pins will line up almost EXACTLY with the timing mark on the sprocket for hte camshaft. That way we knew if it had skipped a tooth or anything. Good luck with an engine swap though.

Here is a pic of the timing cover that started my whole problem

Notice the hole where belt tensioner ground through and the crack through it that split the upper part from the bottom.
