SO i have tried adjusting the timing and it seems worse.



You can't "Adjust timing" on a timing belt without damaging something. Your first video sounded like a normal healthy longblock with maybe an idler pulley ceased causing squealing but now theres internal damage. People here are trying to help you but your doing your own thing... Good luck.


you have a great day. please don't post on my threads any more.

SO, I was lazy and already halfway there so i pulled the head off.and apart from finding all but one of the lifters,(I think they are lifters), destroyed. This was pretty interesting too. The number 4 cylinder looks like it had been not burning well for a while? WTF?

Also here is a closeup. The tip of the glowplug missing.

This sis the state in which the glowplugs came out.

This is what the cylinder wall looks like #4

Image

All the others look like this. Sorry for the blurry pic, but you bet the idea.

This makes sense. Your #4 glow plug tip broke off and must have caused a valve to stick open until the piston hit it, which then caused the rocker arm(s) to fail. Due the the valves no opening properly in #4 the injected fuel burned very poorly causing the soot build up and "wet" look. Make sure the valves are all seated properly, you might only need new rockers, gaskets, head bolts and glow plugs to get it back up an running. Not very cheap, but it could have been worse.

How do i know if the rings are bad or not. I guess as far as i have the motor out now, i should just pull it all the way and pull that piston and inspect the sleeve. What do you think?

If you have a GDE tune or a SEGR to eliminate the CEL with the EGR removed, then get rid of the EGR crossover tube behind the engine, blank off the ports at the exhaust manifold and intake elbow, lose the EGR valve, loopback the EGR coolant lines and call it good. The blank off plate at the exhaust mani would be the perfect place for an EGT probe if one were so inclined.
I'd hot tank that intake/valve cover and get all the gunk out of the ports and install 7V metal glow plugs.

it's a cleaning tank at an automotive machine shop - strips the block down to bare metal
it's the first step on a rebuild process.
after that they can start checking for cracks & damage.
