The check engine light came on and said the throttle sensor was out of range, the code was 0520194/2, I then looked around the engine and saw oil and coolant leaking out of the gasket just above the Polaris sticker. I then checked the oil and saw it was foamy and the coolant was murky. There’s only 5 hours on the new oil change I run 5w-50 full synthetic castrol, it has 28in tires and a uni filter, there’s 2000km’s on it. My questions.
-how do I know if the rest of the engine is OK
-how hard is it to change the head gasket now that I have the gas tank out
-what might have caused this
-could it be any of the things I mentioned above
