WATER IN BREATHER ASSY

What engine?

How's the weather?

Mike

the engine is the 258 and the weather is southeren ontario quinte area . No rain since i last dried out the breather

Ahh, nice sunny day (for this second anyway) here just down the lake a bit in Toronto. It is supposed to hit 15+ C today.

Apparently raining cats and dogs in Brampton.

Our weather has been humid and hot/cold and foggy. The best for condensation...

The reason I mentioned rain is because some YJ's have a ram air scoop just under the headlight for the intake. This can get water into the air filter.

Other than that you are describing an amazing amount of condensation which can and will happen in these low temps. The condensation or the high humid air in the crankcase is supposed to get sucked into the intake manifold via the PCV line at the back of the carb.

I would first pull the PCV valve out and shake it to make sure it rattles.

There are known issues with the solenoid unit at the back of the carb that splits the PCV line into a T with another that goes to the charcoal canister. This thing fails and apparently never did work right. It can be replaced with a T fitting.

If this unit is staying closed when the engine is cold and you never warm the engine up fully, the condensation just builds up in the crankcase and can get sucked into the air filter via the valve cover breather tube.

You also are supposed to have a flexible heat pipe that comes from the bottom of the air filter snout and goes down to the heat stove on the exhaust manifold. This is a tin box on the front of the manifold. This is for cold weather starts and running and sucks warm air into the air filter. If this isn't working or the carb vacuum flaps aren't hooked up, then cold humid air gets sucked in direct.

A 195 thermostat is also best for avoiding condensation.

Meanwhile a good run on the highway to fully heat it up and cook off any water left in the oil would be a good idea.

You aren't missing any antifreeze right?

I was looking under the hood and the line that goes from the canister drivers side to the T fitting at back of carb was split at the T so I cut it off and reinstalled it . The ball in the PVC valves rattles like a charm. The heat pipe is there small crack so I taped it.

Will this water mess with the idle, it has been stalling when warm.

The crack in the line will mess with the idle when that circuit turns on as the engine warms up and cause the condensation by blowing the PCV valve's suction.

I think you likely have found the cause.

You may want to check and see if water has gotten into the oil.
