Removing stuck crank sensor

[Crusarius]

So I started out with an intermittent crank sensor on my 2005 grand Cherokee. Figured no big deal. $20 sensor. easy change, right? boy was I wrong. took probably a total of 6 hours to break it off several times then extract it from the block.

I live in the rust belt so the bung outside the O-ring seal had a very nice thick crusty layer of rust.

I ended up drilling a hole through the center of it then threading a nice big lag screw into it. Since I didn't have a slide hammer I grabbed a piece of bar stock I had laying around and made one. I love having a mill.

Course then I could not install the new sensor due to the rust ring so I spent the next hour trying to clean it out. ended up using a deburring tool and some emery cloth.

Wow I guess I should be glad my daughters Chevy lumina 3.1 v6 crank sensor boots on to timing cover behind harmonic balancer. Man that job sounded rough. I just bought a slide hammer.

Wow, that was quite the job!

I bet having a mill saves you alot of work.

Good job!

It's times like that when you say to yourself "why can't there be an oil leak here to eat up all this rust"?

Thats funny. I was thinking that exact thing the oil is leaking on the other side though
