While installing my new oil temp sender I snapped the adaptor off in the block.
NO, I wasnt over tightening and it didn't cross thread. Well, I guess I did over tighten it but it sure didn't feel like it when I was installing it.


This is the location just above the oil filter mount. And if you have a 4th gen you know it isn't a straight shot to get at, the pictures are deceiving (I used a small, easily placed camera). Can't even really see it from underneith.
I would just install the sender, however it seems some of the adaptor threads are damaged or at least some metal burrs are in the way. It wouldn't thread into the adaptor by hand and I didn't want to ruin that too.
I'm going to try an bolt extractor tomorrow, however I'm concerned with containing any metal particles and keeping them from getting into the oil passage.
I don't think I'll be able to sleep tonight.

Hope you sort it out... and without any major intervention.

Take your time and work through it slowly, when you're not pissed off at it! Working when mad can make things worse!

Good luck!

Make sure you pack the extractor with some heavy wheel bearing grease. That should be able to make all the chips stick to the extractor. The same thing happened to me in my thirdgen, I tapped the extractor in with a hammer then I was able to twist it out nicely. I used the short stubby extractor with a hex on the back side.

I was tempted to mess w/ it last night, but I called it quits so I could deal w/ it when I was thinking w/ a level head. I will use the grease. I don't have an extractor yet, I figured on picking up a #3 or #4 at Home Depot/Lowes. Unless of course there is a recommendation on a better item.

I would recomend these, but maybe a better quality, they're pretty short so you can get them in almost any place and use a ratchet on them. I would stay away from the long skinny versions since they usually have a square cut on the back so you wind up using an adjustble. It just doesn't sound like you can fit an adjustable wrench in the comfortably.

I have had little luck with bolt extractors.

They have a tendency to snap off, then you have hardened steel stuck in the hole. Since this is a blind hole that is a big problem.

If the piece isn't busted off flush, vice grips might work, I couldn't tell from the photo.

It looked like brass, brass will melt before cast iron will. Heat might be an option.

You might also be able to drill the center out as much as possible and use a punch to collapse the fitting and then pull it out.

I wish you luck, that looks like a very anoying task.
