I did a quick search on the net for bore scopes that can do stills and video and connects to Android. Found a decent one off Amazon but wanted to get suggestions first. About to change all 8 coils and plugs for my 98 and wanted to see if recent cleaning of intake valves had any effect on cylinders. I suspect a bit of solvent got down into a few cans whose valves were open. I did have a vacuum hose going, but only for the few initial cleaning sessions. DOH!! Also, would it behoove me to take the time to set up each cylinder at full volume (minimum stroke?) before getting images? I suppose I'd have to use a skinny measuring device down into each one just to get it close. Thanks!
