Hear a leak when rpms get over 3000
I bought my ranger with what was thought to be a blown head gasket, because it was leaking coolant. I brought it into my local shop and they didn't replace the head gasket, instead they put something in to try and seal it without taking the engine apart. Before I brought it to the shop I heard this same sound at the high rpms and it stopped for about 3 weeks now, and the sound is starting again.
