so the other day i had my first experence with my dip stick poping out. so i checked my catch can today and it was almost full. The color of the liquid inside is a odd color and i hoping nothing is wrong. please give me you input on what you think.

thanks Scott

 

That is caused by the oil mixing with water from the condensation build up.

In other words, its normal.

How long did it take for it to fill up that much?

 

That is normal.

 

Catch cans should be checked and possibly emptied every oil change.

 

Totally normal. I pour what looks like coffee (w/ creamer ) out of my catch can. Due to condensation and oil mixing. I notice it happens more so in the winter temps. In the summer there's not as much condensation.

 

That's the stuff that stays in your oil when you don't run a PCV system.

 

How long did it take to accumulate that much? Iv ran a catch can for 5 years with maybe a drop or 2 making it's way to the catch can

 

disturbing, isn't it?

 

I found it depends on how you have the can installed.. I used to simply have it between the drivers side valve cover breather and the intake pipe.. didn't do much and does absolutely nothing when vented.

I then acquired an additional PCV valve and ran the can between the rear of the valve cover and the intake manifold... now the can is "catching" all the crap that normally would be pulled out of the crankcase and back into the engine to get burned. I have to empty it every oil change, more if I'm running E85

 

How was your oil when changed it last? Change it now, is it milky? Yes ur catch can shouldn't be full, but u should also be checking it with every oil change or every other. When I check my catch can it's mostly water mixed with a small amount of oil, but my oil is always perfect when it is changed. Except for "last time" when the motor was shot.

Also my catch can is on the drivers side running into the intake pipe

 

What is the pcv system?

 

Really?

So how does a rerouted PCV system help when you shut your motor off?

 

PCV system is designed to perform 2 operations.

Most important its to relieve positive crank pressure build up. Secondly, its designed to perform that function by recirculating the blow-by gasses back into your intake rather than out into the atmosphere.

There is a lot of debate weather if it "has to be" recirculated for the "vacuum assisted" sealing of the piston rings, or just allowing it to vent out. But thats a whole different topic and you have some extensive searching and testing to do.

 

It had been a long time about 3 oil changes:-( . I did not know it needed to be emptyed every oil change

 

.. a good catch can doesn't "rerouted the PCV system" and it's designed to work when the engine is running and producing moisture and other combustion byproducts.
