Checked my oil today and inside the fill cap and tube was white/yellowish milky crap. There was none on the dip stick and the other day when I had the turbo oil feed line off the oil that came out looked fine. Could this be the result of the turbo sucking up moisture off the road? Its been snowing off and on lately and kind of slushy as well. I did not think being that I have a 4x4 that the cone filter on the turbo would suck up much road gunk. I have been thinking of a way to move the cone filter or adapt my stock airbox with some flow enhancing mods to keep crap out of the intake but did not think I had to do it soo soon. Any suggestions or comments???

 

anytime time that oil has a milky color, it is because of moisture or water.

i am too worried about my intake taking in water. i removed the metal plate beneath my K&N FIPK for more air circulation, but have not noticed any water getting into the CAI. i have had this plate removed for a few years now with no problems.

 

It could just be normal condensation...the oil that comes out of my catch can looks like Yoo-Hoo.

 

Please check to make sure that's not coolant that you are seeing! We've had a few trucks come in my shop with Nitrous and blowers.....that have experianced a cracked head and cracked block. A faulty head gasket will give you these results also. If your buddies are eating your dust, in a race, and at the end they say " what's this sh*t on my windshield"......then you got a real problem and it's now coming out your exhaust!

 

 

Knock on wood, I don't think that a cracked head or blown head gasket is the issue in my case...coolant level hasn't dropped at all, system holds pressure (hot and cold), no smoke, no misfire. Just a little condensation mixing with the oil in the catch can, ever since the weather got cold. I believe that I read here that a few others have experienced the same thing, which definitely helps me sleep better.

 

That coolant/ water in your oil. Blown HD gasket most likely Deal with that real soon or youll be buying everything from the crank up.

 

relax. it is not a cracked head. it is not a blown head gasket. it is not a cracked block. with the cooler temperatures you are seeing right now, hell, even in not so cold temps, it is not uncommon to see the residue you are talking about. wipe it off and go on your way. what thermostat are you running? try changing it back to stock for awhile, if you have a cooler one in it, and see if that helps.

 

My truck is totally stock other than the STS kit and a Nelson tuned pcm. No t-stat no nothing. I don't think its a cracked anything either, the truck runs perfect except for some tune isues that I need to track down. Just thought I would ask to see how many others have seen this. I have never seen this on my truck in 45,000 miles so I had to ask. I crawled under it last night and checked for leaks comming from anywhere and nothing was found....whewww!
I'm going to be looking at using my stock airbox on the intake of the turbo, the thing stock has two big *** holes in it which make up more surface area that the opening of the turbo so I figure it should work as far as flow is concerned. I just hope it keeps crap out of my motor, looks like I have to put a catch can in. Anyone know the post that did the home maid catch can? I really dont care if it looks a little industrail til I can make an aluminum cover for it. Thanks for ALL the feed back everyone, I knew I could count on you guys again...

 

On another note, how can this crap be removed from the engine? Could I use an engine cleaning product like sea foam, I used it to do my top end about 3-4 weeks ago before I installed the turbo. Would an engine cleaning product screw up my turbo? Maybe I should start a new post with this question??? hmmmm.
