Yea this Hyundai was FWD and removing the oil pan wasnt a big deal. Just a pain because it was extra work just to get the engine to spin over. You could also remove the cylinder heads and try putting lube in the cylinders or even tap the pistons with a dead blow

I gave it 1 last try last night, removed fan and got a big socket on the crank bolt, braker bar, cheater bar, it wont move! At least I got the bolt out.

I'm about to start dis-assembling, getting those heads off would give me alot of room, then I could also lube and tap the pistons.

I have never pulled a engine out with the converter attached, dont know what to expect!

(see if this works)

You could take the engine out with the converter attached but it will make a huge mess and possibly damage the converter or transmission shaft.

I got alittle more done! Pully the harmonic balancer, starter, exhause pipes, moter mounts threw bolts

One of the torq converter nuts is in doable range of getting to! 3 to go!

I did read where a guy stuck a box end skinny whench between the rear engine schild and the flex plate and got to the bolts. Anyone know anything about this practice! This could open some doors for guys with stuck engines.

If it was me, I'd pull engine and trans together then split on the floor. Much Much easier.

Just my opinion.

That's what we wound up doing! We pulled the trans back just far enouigh to get a 6 point 9/16" boxend wrench on the torq converter nuts. That wrench was a must!!!!

After that we placed the block on a eng stand and removed the oil pan. Expected to see something twisted up or broken! But see nothing apparent.

Oil pump screen was not clogged but did have a few piece's of crud on it!

We did find metal shaving in the bottom of oil pan, some were large!
picture are up!

Have not removed heads as of yet!

That's where i'm at now!

This same exact thing happened to me last year... i've yet to pull it apart. I'll be following this very closely. Are you planning on rebuilding that engine, or getting a new one? It seems that oreillys has crank rebuild kits for them.

I think I found the problem tonight! 3 of the teeth on the oil pump drive gear are stripped, all the gears are worn sharp.

I had to use a puller to remove the cam gear, it does not slide off! LOL

If you ever have the timing cover off for any reason this would be something to look for!

Looks like the thrust washer might be missing or shot on the crank.

I'm not quite sure what your refering to. If its the large washer that the bolt go's thru, then to the center of the crank, I have it!

Got the cam and balance shaft out now, it looks rough!

There should be (for want of a better word) a shim on the crank shaft to keep it from moving front to back.

The pic of the rod bearings look like the crank has been moving back and forth, so the bearings are worn on the sides.
