Ok, I thought I'd be smart and do my own compression test; well everything's going fine until I realize the end of the tester has unscrewed and is stuck down the spark plug hole! It's the metal tip, about a half inch long or so. Any suggestions on getting it back? Everything I'm trying is just further tightening in there.

 

magnetic tip thingy?! but wait..if its screwed in down there....then i'm clueless....maybe reversing the processes?

 

yeah, it's screwed down into the spark plug hole semi-tight... I knew I shouldn't have gone that tight! Now I know. Maybe lock-tite and let it set?

 

dont put to much, some kid poured it in and had it stick in the head

 

Get a screw remover (left hand thread, looks like a tapered drill bit) and remove the adapter. They are commonly called Easy-outs.

My dad actually just gave me one of these, and it worked like a charm! I've never used one before. Everything else I tried wouldn't give me enough leverage or friction to move it. Thanks for the help.

 

I did the same thing with the Comp tester I bought from Autozone, I forgot to tighten the adaptor to the hose so when I tried to take it off, the adaptor was still in the hole...... You are not supposed to put them in very tight, so screw it back on pretty tight and slowly back it out.... that is what I did or use some lock tight or JB weld if what I suggested dont work..... BTW what was your comp test result

Ya, what ARE your results

 

did you use that extra screw on piece with the compression tester??

i don't think you're suppose to. i made the mistake of doing that also, so what i had to do was use my extension bar and push down real hard while turning it, which caused it to loosen up.

good luck.

700 mile 9:1 motor..... 190 across the board FTW

 

It was 160psi on cylinder 1. I'll know the rest when I do it tomorrow. I was so frustrated and annoyed after two hours of struggling with the tester piece, that I didn't feel like doing the rest of the compression test. I had a leakdown test done about three years ago, and I had 35% leakage on cylinder 1, so I'm not at all surprised I only hit 160. The others were around 10-15% back then, so they should be a little better. As you can see in my signature, this motor only made 210whp @ 9psi, which is low for an LS. I'm just testing the engine for curiousity's sake. I think it's a miracle the motor's held up this long. I credit the Hondata tune; 12:1 FMU and an inline fuel pump does not count as tuning! The number 1 cylinder had that 35% leak after only a year of boosting 6.5psi which that setup.

 

Did a full test again today and got 170-160-165-175. Much better than I'd have thought with this motor. It has 80k miles on it, ~30k on the turbo. When I get some more money I'll likely up the boost a bit and take more risks, b/c I'd like to drop another motor (built or semi-built) in there anyway.

 

yeah thats happen to me before too. I the adapter was a little bigger then 5/8" so I figured out what size socket it was and grounded down the whole entire socket so that it would slide into the sparkplug cylinder.
