@@JustCantSitStill we did a cam swap, replaced lifters (had a bad one) head gaskets etc. last week. how common is it to have an oily film floating at the top of the radiator afterward? Do you think flushing the radiator/cooling system would clean this up? Motor oil looks good. Thanks
@@arnoldrodriguez3803 I would bet its common as oil may have gotten into a cooling passage during the head removal and lifter replacement. A flush should solve the issue.
