Well I've done it now. Does a 1997 1.6 corolla have removable spark plug tubes?
I was doing a compression test on my son's car and the compression tester adaptor got stuck in the spark plug hole.
I didn't notice it until it was to late and now it's stuck down in there pretty good. I think the only way I can get it out is to remove the value cover and if possible remove the tube, that seems to be the only way to get a good enough grip on the adaptor. I worried that the tube will be damaged it it's not suppose to come off. Do they screw on and off or a I gently pull it out? Many thanks
