Re: GM Top Engine Cleaner i try to let it sit overnight if possible. (have you ever tryed to scratch carbon off a piston?) to get it in each plug hole use a piece of air shock or fish tank tubing or vac hose and spray through that <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> it works like a charm and try to use gm products they spend $$$ developing this stuff for their techs. and they dont like paying for something they did (can you say piston slap?)

Re: GM Top Engine Cleaner Hhhhmmmm, a section of vacuum hose. That is a good idea for getting the stuff into the pass. side sparkplug holes. Think 2 feet with a 3/8" ID will do the trick?
