Stuff in catchcan, HG???

[mitsuclipsegsx]

Well this stuff was in my catch can,lines, and oil cap, but I drained oil and oil filter and its fine. Could it be a small HG leak? Seems like its in the valve cover but nothing else.

looks like water mixed with oil
do a compression test, check the water in the radiator
is the car overheating?

also it could be humidity

 

[mitsuclipsegsx]

I did a compression, 190,180,190,190, not overheating, I will have to check the coolant level. Its also been in the garage since Dec.
thanks

Just need a leakdown test on each cylinder, doesn't look that bad. Have a stock catch can and egr/emmissions setup?

 

[andy4g63]

You don't have to do shit!!!

It is allways been like that. The water comes from condensation from the motor and the oil gets slushy and nasty looking, it's normal. If everything runs smooth, fine, as it did before don't worry.

Guy from dsmlink wrote this." If you run both valve cover vent locations to a catch can you need to take the pcv valve out and just run a barb, like the one from the stock intake manifold to the pcv valve. Right now in your case the pcv valve is a check valve that will never open so you will only have one vent from the valve cover. Either way this will not fix your condensation build up problem. You need to supply a constant vacuum source to the crank case.

The best thing to do would be
A. cap off the one nipple on catch can and reconnect pcv valve to the intake mani

or

B. replace pcv with barb and replace catch can breather filter with a vacuum line to the intake pipe between maf and turbo."


What are you people that are running a magnus/jmf doing?

 

[nightracer91]

That's just moisture. That's the milky look you here about when water gets in oil. Most catch cans condensate some moisture giving that look to the oil in the can. mitsuclipsegsx is right, thats really your only two options to comletely rid of the moisture.

I'm kind of interested to find out too. If it's plumbed the way I think it is, his crankcase ventilation system isn't working correctly.

 

[ed_GST]

the explanation the guys from DSMLink gave you makes sense

what type of catch can you have ?

 

[mitsuclipsegsx]

jmf.

You can't ever get rid of the moisture. There allways will be some. I run JMF large catch can, connected via -10AN hoses to the side and rear of valve cover/PCV eliminated/ and I additionally drilled the VC to enlarge these holes. I have 0 BLOW BY, but allways a little amount of water, like an ounce or two over a few months and is mixing with the vapors from the oil and looks milky. I remember the first time I've seen it, I was afraid that something is wrong, but the gut that build the motor, said: this is condensation, don't worry.

Here are afew pics fo the set-up:

Am I wrong when I assume that you need a line going back to the Intake to pull vacuum on the catch can? This is what I always thought you needed.

 

[andy4g63]

I don't think you need that/not sure/, buut it is like that on stock cars, so this stuff can be burned and thrown out the exhaust. It is probably part of emissions process.

 

[boostforfun]

Well, if the crap enters at the bottom of the can and goes through some steel mesh and baffles, and the vapors are pulled through my the vacuum source, there wouldn't be much junk going back into the intake. Seems like it would seperate better.

You do - catch cans setup that way with a breather filter aren't setup correctly. You need an active vacuum source to remove blowby from the crankcase. Really, all you need is to put a catchcan between the intake and the PCV valve, with a checkvalve in between the intake and the catchcan to hold back your boost. Have the outlet on the left of the valve cover hosed up to the intake and you'd be all set. There's other ways of setting it up, but a breather filter shouldn't be involved with any of them - you'd either be purging metered air or introducing unmetered air, provided you are using a vacuum source. It has less to do with emissions and more to do with reducing contamination of your oil.

If it's been sitting a while it's probably just condensation. Garages get very damp. I wouldn't consider it anything other than normal. Run the car to get the oil warmed up good and then change it.

Everything you said is correctly for a stock appearing car. My car is SD based and I don't have anything to do with what you said. PCV, or check valve is needed, if connected to IM.
Mine isn't..
In my case, I have a breather filter, cause this pressure from crankcase, valvecover have to vent somewhere. I don't have PCV/check valve whatsoever, because there is no boost present at the sourses where the hoses are attached.

Third, there is a difference between catch can ONLY and catch can/breather...
On all big dog cars, the catchcan/breather set-ups are set similar, with Filter-breather !!!

They aren't setup correctly like this on stock cars. I've ran it this way and I've had much better luck with blowby/positive crankcase pressure.

To the OP, I would try and run it exactly how lacroixdp said, with the exception of getting another catch can and putting inbetween the intake pipe and valve cover. Some people make their own catch can thats essentaly two in one to take up less space too.

Edit: aww crap Andy, you beat me to it!

Hmm... I didn't notice you were using a SD setup. I think there was a discussion years ago on here (Maybe circa-2005) and the consensus was even with your setup, you should still have a traditional PCV-based system. Then again, that was years ago

 

[andy4g63]

No problem, we just trying to make it right for the OP and anyone else. It is a friendly discussion.
