Let me clarify, coolant in the oil and/or thru the intake/SC down to the piston chamber(where the spark plug is). you could possibly suck coolant from the Throttle body passages if u have a leak there like i did. From now on I will literally, throughly, specifically, explain everything 100%. Figured u guys would put two n two together and comprehend what im saying. Not yal fault, im just being LAZY with the typing.....Long weekend
