Customer Question
I'm noticing a few drops...
I have a Detroit 60 series 12.7 with 417,000 on overhaul. I'm noticing a few drops of oil (puddle the size of a silver dollar) every morning under breather in front of oil filters. Should this cause concern?

good afternoon my name is ***** ***** I will assist

any oil leak is a concern. are you sure where it is coming from??? if not, clean the area with brake kleen and then check for the source.

there is the oil filters, oil switch and the oil cooler itself there as well. are all those areas dry???

can you post a picture of the leak???

I followed the vent all the way to the top of the motor and there in no electrical connector.
Technician: roybelding, Shop Foreman Freightliner trucks replied 2 years ago

ok, thats the one from the valve cover. remove the line from the cover and see if there is a screen in there. it is like a piece of steel wool.

the one I sent was for the block, sorry

This is the one leaking. It's the vent that is seen in my first pic that comes all the way down to in front of the oil filters. Is that a problem to have oil dripping out this line from valve cover?
Technician: roybelding, Shop Foreman Freightliner trucks replied 2 years ago

no, thats why I said to remove it and see if the filter is intact. there is a separator that is actually a piece of steel wool like material that keeps the oil there and lets out air

I haven't taking it off yet. Hopefully this afternoon.
Technician: roybelding, Shop Foreman Freightliner trucks replied 2 years ago

ok

Customer reply replied 2 years ago
I took it off and there isn't any kind of filter or material, just an open whole. I can't find any part # ***** what this would even be called. I called a local shop and he said there isn't supposed to be anything in there. What are your thoughts?
Technician: roybelding, Shop Foreman Freightliner trucks replied 2 years ago

it is part of the valve cover. I have never seen any part number for it.

like I said, we use a steel wool type of material to absorb any oil slung around under the valve cover.

Roy

Customer reply replied 2 years ago
could it have dislodged itself and its floating around inside valve cover?
Technician: roybelding, Shop Foreman Freightliner trucks replied 2 years ago

possible or someone left out when the cover was off
