Going to post some pictures that were taken with my new SnakeScope clone from Harbor Freight so may not be the best as I have not mastered its' use yet but not a bad deal reg $249 on sale for $199 and a 25% off coupon gets it for $150. Big screen b/w and color .3 inch head (goes right down the plug hole) and also will go through the EP or IP and out the other side with adjustable light, pan and zoom. Pictures downloadable to computer or TV, as well as movie capability, and a micro SD card slot max 16 Gig. I have not tried but it may even fit beneath the piston at TDC and allow you to look at the crank. If the pictures don't come out well I will take some more.
