Im less than 1k on last oil change, i have been commuting with the car 40miles a day or so to work. Is this normal? i did a search and came to teh conclusion that it may be typical with rotays somewhat?. Dipstick oil is ok. Running temps are ok, doesnt overheat, i typically let the car idle in the mornings to warm up before i head to work and allow a cool down period whenever i park.

 

Is your PCV system hooked up? If it's gone, you'll get that kind of buildup.

 

ill check it out. freaking cap was super tight to get off..

 

looks like ill have to do a catch can, i dont see any pcv setup, just a straight hose plumbed on the filler neck hose, i suppose the pcv valve would be around there?

 

If your car had a head gasket, it would be blown. Looks like coolant is in the oil. Are you loosing coolant?

 

coolant levels are fine, been staying at the same levels.. im willing to bet its pcv system or lack of in my car since i didnt build it. I just never drove it all the time like i do now so i never seen that.. Im gonna do a catch can setup.

 

its fairly common...that **** looks pretty nasty though. that reminds me, i need to check my car.

 

I've never seen it but most say turbos are like that, my n/a has _nothing_ there, at all.

I don't think the oils been changed in quite a long long time either, it's black haha. So it must be normal

 

That is from moisture evaporating out of your oil and condensing in the filler neck. If you check your compression, you will probably notice it isn't the best. The most common reason we get this is worn or loose clearance side seals on turbo engines. This causes blow by. The fuel goes into your oil, then evaporates later. I had a pretty bad problem with it before my last rebuild.

 

coxxoc, wouldnt he notice his oil smells like gas? I've had bad blowby when I ran 5w20 or whatever the thin oil is, you could see the oil was thin and reaked like gas, ever since I switched to a higher weight oil it dosnt smell like gas much and is thick always

 

Not necessarily. The gas will evaporate. There will always be a little blow by. That is inevitable. If you run higher boost there will be more. If you have the car at full operating temp when you drive and don't boost it a bunch, it will go away.

FWIW, there really is not a big problem with the build up. A good catch can will help catch most of the oil mist and vapors that make up that junk rather than having it go back to your oil pan. The alternate method is to plumb it back into your intake pre-turbo from one of those nipples on the filler neck. That is how it is run on most stock cars with a PCV valve.

 

thanks for the words of wisdom coxxoc, much appreciated!

 

Mine smells like gas, slighly white looking foam. Compression is fine. Haven't had any problems. My oil filler neck is just vented though, w/ filter on it.
