Update. my brother took my car to our local independent MB mechainc to have the idler bushigs replaced and then have it aligned. I still don't see how people get the idler bushings out, I've tried everything. Anyways, he saw a puddle in the bottom channel of the oil cooler and said my cooler is actually leaking, not the lines becasue it was only wet at the bottom and not at the top where the top line mounts. Is it very normal for an oil cooler to leak like that?
Thanks
David
