Guys- I apologize in advance for the lengthy post.. But please shoot me your insight on this.

I was running another compression test with my brother on my01 late last night after doing some mods to the car. The numbers were good 230-240ish.

To make a long story short, as we were finishing up on cylinder 1 ( closest to the radiator) .... I was pulling the compression gauge ( its an ACTRON from advanced) from the #1, the adapter did not come out, however I did not notice this, since this is the first tester I have ever see with a screw on adapter...F$#@!!!!!

Anyways not aware of this I grabbed my spark plug and screwed it in the adapter (can you believe its the same 14mm thread as the plug( Ohhh the Humanity!! !!!!)
as I was screwing it in I felt some binding and quickly pulled the plug back out and realized what I had done.



So the outcome essentially is, I have my compression tester adapter torqued ( 10-15 lbs) in the cylinder head of #1 and 2 small pieces of ceramic fractured off from the inside of the plug as it was being screwed down in to the adapter/ head......

I have no idea how to get the adapter out, however I was planning to put a fiber optic camera down to head If I can get the adapter out and vacuuming out the ceramic fractures off the top of the piston.





I have no clue how to get the adapter out, it looks like a 17mm socket would fit it, however nothing bigger than a 16 will fit down those tubes. Its threaded internally for the gauge to tighten in however it torque in there enough to not be removed with needle nose etc ...



PLEASE HELP with ideas.....[SIZE=7]

 

hopefully it doesn't get ugly and you have to tear it all apart...

good luck...

 

My first thought was vacuum and drill pilot holes to wrench the adapter out..... what a mess man

A pic of what we're talking about would probably help us all develop a plan.

 

Will a Sears "extractor" or similar tool fit inside the adaptor and let you back it out?

I assume you don't mind wrecking the adaptor.

 

If the gauge uses a solid metal tube, red loctite it into the adapeer and let it set. I'd rather wreck a compression tester myself.

 

The above was my thought, left handed thread, so as it screws in tighter it may release the adaptor, known to me as an "easy-out". May or may not fck the adaptor, it'll depend on how tight is screwed in.?

 

Or..why not gut the bad plug and loctite it in. I bet the wrench will get that out.

 

Thanks for all the good thoughts guys.

I just got back from the auto with some long needle nose plyers to try and grab a hold of the extension itself, but its to tight in there to reach the outside diameter. Like I said its probably torqued around 15-20 foot pounds.

I just cleaned up the old plug threads with a wire brush and gutted the rest of it. Applied a liberal amount of permanent lock tight and snugged her down. Solid idea SgtB. It sets in 20-60 minutes but I'm going to give it a few hours to be safe.

I also grabbed a screw extractor kit from SEARS in case the loc tite doesn't hold ( PROPS ON THE IDEA), but I'm banking on the loc tite doing the job- If it truly does make a permanent bond, 15-20 lbs should easily be within its holding limits.

This happened to me once on my old car. It took me a while to figure out what happened. I thought the threads on the head were jacked up and i was screwed. But the adapter came back out when i put the tester back in.

 

This is the best option but just so you know with locktight more is not better. Just use a few drops
