I was performing a compression test on my ITR this weekend and on the second cylinder the threaded hose would not unscrew from the cylinder head. I tried and tried to unscrew it until the hose would flex and turn. After many unsuccessful attempts the hose is nearly shred in two. I've already removed the valve cover and found the longest needle nose pliers with a circular angled tip and I can't get a grip on anything metallic, just shredded rubber

Short of removing the head to drill it out, does any one have a suggestion?

btw-it's a circular fitting, not a six-point item, that I can throw a deep well socket on and remove

 

rip off the hose
ram an extractor in there
happened to me once with a tester made in 77

 

Just when you thought you heard everything...
The hose is useless at this point so pull it all the way off. Try to wedge something of appropriate size down the hole that was the hose. Maybe a screwdriver and turn it out. Should not be that tightly screwed in. Just try difff sized screwdrivers until one sticks.

 

the exact same thing happened to me on my last car with a round head tester plug also, the hose eventually just came off from twisting/turning it, so i got a screw driver and pushed out the top of the tester head in two places then got a chisel that fitted in and wedged it into the place where i had widened the top of the hose fitting and screwed it out.

 

this happend to me also, except i had an adapter piece and the hose unscrewed without the adapter piece, luckly a little thread lock on it screwed it back in, then turned it out after it dried, FEW!

 

lol. I figured it out before I read all these responses.....I guess I shouldn't have been working so diligently (at work) today and checked the board sooner

Anyway, one of my buddies stopped by to take a look and survey the situation. He yanked off the hose, used the nice needle nose pliers and got it out for me while I was on the phone with my dad.

Amazing how easy it was once the hose was removed! Thanks for all the help.

 

i did the thread lock too and it worked great! glad I thought of that at the time.

 

This just happened to me the other day and I come on the forum and prayed to find a solution...and I did !! Well my problem was that the whole tester plus the adapter were stuck. That's because I tightened the adapter to the tester with wrenches first. Anyways, it was stuck so I put two cap fulls of synthetic oil down the tube and let it sit for about 4 hours. Then the engine was cold and I used 11" needle nose plyars and put them down the hole and turned it out.

 

Thread locker works great, same thing happen to me and I used thread locker. And when you get it out, make sure you thread lock the piece to the compressor so it don't happen again.

 

dont forget to put a little bit of oil on the threads too
