Hello guys,
Here are the pics and the video.
In summary:
- Collect all broken parts, to check if there are any missing.
The only thing that still missing is the "C" clip of one of the
lifter. The other lifter that had the "failure" seems ok. So maybe it
was not a lifter failure but a stud failure or the metalic piece that
is holding the lifters maybe. Do not know...
- Check the damaged push-rods if are bended
They seem ok. Watch the video around: 3:20
- Check the lifter adjustment (preload) on another lifter
Not sure here. It needed around 3/4 of a full turn to start moving
up-down. Some needed less turn. See video around 4:10
- Do the leak down test for possible damage on valves or pistons
The valves have some leaks. Of course the piston rings have leak (that
is normal) but you can see the bubbles? Are not perfect in my opinion.
But I think there was no hit / damage - seems they all have the same
leak. I think that need to fix that since is resulting in loosing
performance?
- Drop pan inspect rods and crank
They look ok.
Note: If you look closer to the bottom of the rocker arms - most of
them have serious contact with the valve spring cap. Also the valve
"tip" is not higher that the valve spring cap. They are about the same
height. Is that normal? Look at image: (valve_cap_side_small.jpg).
Another damage that we have found is in the distributor rod. I am not
sure what is the name of it. How this is damaged - I have no idea. I
took it out very gently so it was not dis-assembly error. Trust me on
that! After all, this rod has some strength and thickness - no way I
can break it with my hands.
I am thinking to also open the cylinder heads to check if the is any
rod damage / bend?
Also to improve the valves and cylinder heads to have no leak. The
reason I am thinking that is because if the exhaust valve was not
working then fuel was going in and then? Maybe the piston vs fuel
liquid bend the rod? Is that possible?
In case I forgot something I will add it...
Also if you need hi-resolution pics let me know....
