Ok so i pulled my plugs today and i looked into the cylinders and what do i see? The swain coating is falling off the pistons. This engine has somewhere around 2000 miles or so. What kind of problems will this cause? Will i get pistons slap or something like that? All help would be appreciate it.





Thank you guys,

Looks like paint chipping off a wall, or a bumper. Some of the pistons had like bubbles on it like if the coating was bubbling up. Like when someone doesnt paint your bumper right and it bubbles up?

 

Checked the pistons again now and they all have carbon in them except number 2 cylinder which has a little bit that looks like gas dripped in there and dried up turning black. Its weird. These pistons never burn even. It ran for less than half an hour from the time i checked them last night to right now that i checked them again and they changed like this. I think maybe what i saw was carbon coming off? Well also, the plugs were brown with a slight glaze of white color over it. Like tiny miny sprinkles as if dust had just gotten on them when i pulled it out. Hmm, could it be some slight detonation?

We will see how rich you are running if we get the exhaust leaks fixed this weekend. The slight glaze is probably a little bit of fuel from running so rich. Also, it might not be the Swain coating coming off. It's most likely carbon build up like you above. Time to get some Top Engine Cleaner from GM and get a more ideal tune.
