I understand what your saying and it makes sense. I was simply asking about the bypass filters for future reference, thanks for helping out with that. I am fairly convinced that the lead is coming from the cooler. I say that because if there were that much lead coming from a bearing it should be making a decent amount of noise I would think. I will have to do some thinking on what the best way to bypass the oil cooler is, as I mentioned earlier it has very stiff hydraulic lines going to all of it so it not like I can just reroute it. I might have to completely bypass the whole system and just screw a regular filter onto it, which again is easier said than done.
