I have a turbo gsr in my EJ8

Wiscos 81.5mm (close piston to wall clearnce if it matters .0025in i think)

Im running the two block fittings
off the back and the catch can is draining back. when i pull off the filter to the catch can the oil that is settled in there is all milky (brightly)

Is this ok

technically no, if it is draining back.

if it is an open element pcv system, it will pick up the moisture in the air.

is it milky under our valve cover? if not dont worry. maybe put a petcock on the drainback, and drain it when it gets full.

i dont know if i'd want that oil getting back in my system. it contains gas and other stuff. i just empty my can and throw it out every so often. mine is open air no drainback, and it does get milky looking at the bottom

sounds normal, but I would def get rid of the drain back. the **** I poor out of my can I def would not want it going back into my engine.

only time you need a drain back, is when you are making a pass and your catch can cannot handle the ammount of oil your engine passes.

The milky filter is probably from outside moisture as stated above, and like Mikey said pull the valvecover and if its not milky under there I wouldnt worry. I dont see what the big deal is about draining back into the system, where do you think all those contaminates came from in the first place? If the stuff would of never made it into the can it would be in the engine anyway, I cant tell you what my can has in it its always empty and I run -12 lines so I dont think I push much oil at all, I change my oil every 1k miles or so and I am not worried about it. My oil does smell really contaminated when I do change it but it smelled that way then I just had an Endyn can with no drain back.

wrong and wrong. that **** is milky cause it stays in the can and gets exposed to moisture and blowby, if you two were right then your god damn oil would have been just as milky before you installed the catch can, you think you install a catch can then suddenly milky oil is being produced by your engine and the can catches it?

I used to have a non drain back setup and the can was full of milky oil, it filled up so fast and often i made it drain back and my oil is always crystal clear now!

Ok, I pulled my valve cover and looks normal!
I change my oil often and it looks like honney each time.
Sounds like everything is ok and i agree, I too think its from the atmosphere and hot oil.
Thanks for the replies+++

slow down dude. im perfectly aware that the catchcan oil looks milky because of condensation that occurs in the can, not because im mixing coolant in my oil in the motor and that combination is making its way into my catchcan. even if it has a drainback, condensation would still occur on the baffles in the can due to the temperature differences between the hotter can and the cooler air by the breather. I tought this to my 10th graders today, if you need a refresher you can come sit in on my class tomorrow.

with that being said, i wouldnt want the oil that now has water (caused by condensation) returning back into my engine. to each their own

The only time that I saw Milkey oil is when I submerged my quad in water????

I have no idea what your saying here, there is no HUGE temperature difference like you think between the can and the air around it, engine bays are hot places, the can will be hot there both hot, no condensation will occur, my tubes are clear and i can clearly see that the oil returning to my engine is clean, now i will gladly come and sit down with your 10th graders assuming there are females in the class
