4TEC 215hp oil leak areas

[shore]

I may or may not be chasing down an oil leak. I can't locate it.

I don't see it on oil filter cap at o-rings.
I didn't feel anything around oil cooler

I don't see anything obvious.

It seems to happen only when running and is a small amount dripping out the hull drain plug a day after being ran on water at speed.

I see the following as areas.

knock sensor on intake side underneath.
starter o-rings on exhaust side
valve cover gasket
oil cooler on intake side
oil separator/fill on front

I'm looking at the parts diagram to find these areas.

PTO bearing/boot....They are known for leaking...

are you speaking of the bellow and carbon seal?

I did indeed see some freshish drops of oil right under that bellow in the bilge. I was able to feel under it and it had some residue on my hand.

What's the procedure for changing this or leave it alone or?

The bearing that holds your drive shaft right before it goes into the motor, be sure the clamp that keeps it secured into the boot is still properly holding it, there's also 2 o rings inside that bearing that could be worn. Also check where the stator wires come through the pto cover

The parts diagram show this as a "multi-piece" part. Ball bearing with bellow is description. It has a half moon cover that I recognize.

is this a pull pump and driveshaft, then slip that ball bearing and bellow out and replace or is there more to this?

Pulled the SC hose and lifted up that half moon. There is no evidence of oil coming out the front where the shaft goes in, if I am thinking about this correctly. There is also no Oetiker clamp on the bellow. I can see the imprint but no clamp. Back towards the engine/PTO cover, it is more wet. Don't see any drips but it's not dry like under the half moon boot of the bellow.

Felt around bottom side of oil cooler and nothing wet there, either.
Can't seem to get my hands on the PTO wiring harness.
