blowby Help

How can I reduce the amount of blow by coming out of my dipstick without a overhaul of the motor at this time.

More details might yield more useful answers- (1) which machine do you have? (2) how many hours on same? (3) did the blow by increase suddenly or gradually?

The first thing you'll want to check is the breather tube, it could be a valve assembly on the rocker cover that routes fumes back into the air intake. They are supposed to allow pressure out, but not suck air in, and they will sometimes carbon up and not work properly.

Thanks flyerdan 1 more question where's the breather located on my 873 and I assume it goes to the intake breather box correct.

I have no idea where it would be. Assuming it would be similar to an automotive app, I'd start looking on the valve cover for a grommeted in item with a hose going away toward the air intake. Given that it has a turbo it could be covered up with some additional plumbing
