"It begins to crank but just stops". The odds are that you have hydrolocked a cylinder and the snake oil is preventing the engine from turning over. Remove ALL the spark plugs and roll the engine over to clear the liquid from the cylinder(s). Pray that you have not cracked a piston or bent a rod.

Never try to run any sort of aftermarket liquids or snake oils through an engine unless it goes in through the gas tank (even then, 99.9% of the time, you don't need it).

You sure you did what you said? I don't condone the snake oils either, but I've never heard of anyone hydrolocking using the procedure spelled out on the bottle. They tell you to use a vacuum line so that the snake oil intake is regulated a little, as opposed to dumping it down the throttle body.

What vacuum line did you use?

While you have the plugs out, clean that SeaScum crap off of them before reinstalling them.

This morning at 0800 I was in the local Western Auto having the oil, filter, and battery changed in the truck (7.5 years is enough for a battery.....) Idling around, reading can labels. Standing at a rack reading the blurb on a can of Seafoam (the cutesy bullet-shaped one). One of the mechanics walked by and quietly said "Don't".
