Hi guys i see coolant in my cylinder one and a bit of oil leak inside cylinder 4. what does that mean , i have cheked both coolant and oil and it doesnt look like they mixed with each other . i dont know how come it doesnt mix with each other but appears in cylinders. and i have a misfiring problem is that the cause of it?

 

First, yes - oil and/or coolant in the cylinders will cause misfires.

The coolant can only be getting into the cylinder due to a blown head gasket (and possibly warped head).

The oil can only be getting into the cylinder via broken or seriously worn rings.

Sounds like some major work is in store for you (whether that means pulling your engine and having it rebuilt, or by installing a "new, used" engine).
