Columbia glider s60 crankcase vent

If its smoking that bad out of the blowby tube at idle, sounds like its in need of a freshen up rebuild at the least. Shouldnt be breathing that heavy at stoplights unless you just came off a long pull.

 

I've had this issue before with some other Detroit Series-60 14.0L engines. The blow-by coming from the vent can be unbearable at times.

So, here is what I have done. I purchased a plastic plumbing union from a local hardware store like ACE or Lowe's/Home Depot. I press it in to the crankcase vent and put a hose clamp on it and then I use a piece of 1" flex hose/tubing and extend the crankcase vent and ran it alongside the transmission and zip tie it in place. It totally eliminated the problem for me.

Just getting the crankcase vent further away from the HVAC fresh air inlet changed the situation and I haven't had any issues.

 

Driving a dump truck.

I routed alllll the way to behind the rear drives

One idea that would be nice is to route in to the exhaust.

Or the air filter for reburn.

 

Blow-by on my Series 60 looks excessive compared to some motors, but my engine is healthy. The oil made a huge mess on the front of my right side fuel tank. I put an oil trap on the blow-by tube and it has helped some. I liken it to owning a Harley. They all mark their spot, but that is a small price to pay not to have an emissions motor.
