yea when I swap out the bolt I'm going to be very careful and keep pressure on the front hub.

trying to get my mind on this.
Do you mean you have so much wobble that the E sensor is misreading and that is why the spark is not there?
You have so much wobble you can see it a cranking speeds?
That a lotta wobble.
Wonder if the plate got bent some way?
because you have proper clearances--right?

Yep clearances were good. I just got the bolt out now. its actually not as bad as I remembered bottom two threads are slightly mangled nothing major.

I have a good condition one coming in the mail hopefully by friday. Thanks to RR.

Everything seems fine.

If I pull the hub/pulley boss out that's when my stack falls correct?

It's wobbling from one end of the sensor to the other. so I imagine thats why its not firing.

The question is should I pull the engine to put this bearing back in place or try and do it with the engine in the bay?

How many mm from the end of the e-shaft to the face of the pulley boss.

Probably, not always.

dont tell me you put too much RTV, it broke off and it clogged the oil sender (forgot what it was called) inside the pan.

wow umm no hahaha.

The end play spacer did not fully seat. the front bearing was sideways on the spacer digging into it and the front counterweight. there are markings on the front counterweight and sadly I think I will need a new one since these markings could interfere with proper operation.

The thrust washer on the front CW was chewed up? I'm just trying to figure out where on the CW you have damage.

Today's my first day of actual desk jockey work since august of last year. I'll try and snap some photos for all of you its quite amazing. since I had free range of motion on the stack. I almost sealed it all back up but decided to remove the CW just to double check everything. The front bearing actually turned into a spring!

Why are you removing the oil pan?

The plate was chewed completely through and the collar had needle pin marks on it.
