So i have spent hours today changing my Coolant flushing the whole van twice until water ran through clear, lovely!!! i was using a large flat box lid to catch the coolant and after i finished the coolant job i glanced at remaining liquid in the lid and it looked very oily so i touched it and holy crap it had thick oil in it and pretty deep, also on the top of the engine block it has two small oil pools, i am pretty much a novice on stuff like this and have no idea whats caused it but im crapping myself.
Any experts who knows whats just happened i would really appreciate the help,
Thanks.
