Guys, how do I know if a cylinder is infected by coolant ??? how could I tell by looking at the spark plug.

Reason for asking is that as you know I had an external coolant leak that was temporary fixed with an anti-leak powder, but I'd like to keep monitoring the thing by checking the spark plugs to see if I have an internal leak.

My coolant seem to keep on coming down very slowly, but absolutely no droppoing on the ground or along the engine. I have no white puff of smoke on start-up or bubbling in the expansion tank. But today the truck was idling funny, like shacking. So I have a feeling that this was due to coolant in a cylinder, hence why I want to pull the plugs out to see.

So......I'd like to know what a coolant infected plug would look like



Thanks,

Steph

 

Nevermind, checked the plugs and although all bank2 plugs were black, there was no sign of coolant whatsoever.
