Airbox check valve part number

[Messi]

I'm looking for a part number for the airbox check valves for 6v92. The srings inside mine are in pieces.

Thanks

Does your DDC manuals offer this info?

Part number should be 08996207 .
I may have a couple of used ones in my shop.

My shop is still piled up with stuff from the local floods.
If you need one, give me a few days to fine one.

I have four brand new valves, as they don't fit older natural engines. found out the hard way.

Won't work on an in-line block, Never tried on an natural V block.
With out checking into it, I would have assumed they would work on the natural V blocks.
What issues did you have?

My 1986 12V71TIs did not originally come with them, there installed now.
Costume collection bottle, old used booze bottles.

No rush, but I need 1, maybe two. Both were stuck wide open, and motor was not running great. I took apart to clean, and the spring had broken to bits. I realize this would make then say closed....all the gunk was holding them open

Not running great?
Lets get yours fixed or replaced, but I don't think it is going to fix your not running great issue.

When not running and at idle, these valves are open allowing some dirty slobber to drain out of your air box.
They close just past idle and offer just a micro bit more air box pressure. Offering just a micro bit more torque at high RPM.

I have added them to engines that never had them (like mine) and never noticed any difference, just cleaner bilges.

wrong thread size. The valves are, without looking at them, 1/4" maybe. the existing is around 1/8 thread flare 90's to rigid tubing then hose to whatever plastic jug stuffed with oil absorbent cloths, the jury rig work fine. Throw the plastic jugs out a couple times a year and replace them with new discarded jugs

I have not found the two I was looking for. They are somewhere safe.
I did find one in another bin.
Seems to be in good used shape.
PM me your mail address and I send it out the next time I'm by a post office.
