I went to my cousin’s to do a leak down test on his corolla, the one i am thinking about flipping. The leak down tool was sized to larger sparkplugs but came with a screw on attachment for his smaller plugs. Well that attachment did not unscrew with the attachment and is now such in the sparkplug hole. Fuck. We put locktite on there with hope that the attachment would lock to the tool and left to allow it to set over night. Wtf.
