Re: WATER IN BREATHER ASSY
 

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?

Re: WATER IN BREATHER ASSY
 

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.
