What Is This And Why Is It Doing It??

thereal2v2fear · January 4th, 2012, 05:55 PM

I went to go change my oil after my first 50 miles with the new 4.75 in and noticed a little bit of this white stuff on my oil cap but none in the filler neck.. when i drained the oil none of that white stuff came out so i ignored it. well i hit my 600 mile break in and went to change the oil again and this time it was a lot thicker and was all the way down the filler neck and is on my breather filter where the pcv used to be.. I haven't drained the oil yet but will be soon.

none of that was in the oil? does it have a smell? looks like oil and water mixed to me.

thereal2v2fear · January 4th, 2012, 06:03 PM

i didn't smell it. but i was thinking the same thing... I agree it does look like oil and water mixed but what would cause it to mix??

I have heard its condensation From not letting your car fully heat up before you shut it off. I don't know if you do this or not but try to warming it up in the morning or after it sits for long periods of time where it fully cools

thereal2v2fear · January 4th, 2012, 06:13 PM

I always let it fully warm up before I take off or shut it off because its a new motor.

Jsz281GT · January 4th, 2012, 06:15 PM

O that's good. that's just what I have heard sorry couldn't help

thereal2v2fear · January 4th, 2012, 06:18 PM

it's ok thanks for the suggestion tho lol.

Scott2001GT · January 4th, 2012, 06:42 PM

Totally normal. Like said its condensation

thereal2v2fear · January 4th, 2012, 06:49 PM

it freaks me out lol. the old 4.6 never did this.

Scott2001GT · January 4th, 2012, 06:53 PM

Mine has it. As long as your not seeing any on your dip stick it's ok.

Scott2001GT · January 4th, 2012, 06:56 PM

Milky looking substance on oil cap..... - F150online Forums

sharkbait · January 4th, 2012, 06:58 PM

Mine does it to.

thereal2v2fear · January 4th, 2012, 06:59 PM

i didn't bother checking that. good call. i just looked at it and theres just oil on it. sorry if I'm freaking out.. just kinda scared to have dumped a crap ton of money into the motor and car for something to be wrong with it.

+1. Mine gets it every winter.

There's f150's that come into my work with the filler necks so full of that shit you've gotta ram a punch down it all before you put oil in it. I dunno why f150's always get it so bad but all well.

stal94gt · January 4th, 2012, 10:47 PM

as said before, its normal. especally running open breathers. it is most common during cold days

limited · January 4th, 2012, 10:55 PM

condensation is a normal occurance, but not at 50 miles. loosing any coolant?

mustanginky · January 5th, 2012, 08:18 PM

my motor had the same thing going on when i built it, scared the hell out of me. just condensation. i drained the oil immediately too but no issues came up thank god!

SSG Pate · January 5th, 2012, 10:15 PM

Mine did the same thing, There is also some residual chemicals on the metal that will burn off and get into the oil that is why they tell reccomend the change at such short intervals.

limited · January 5th, 2012, 10:20 PM

Must be the humidity form where you guys are that are experiencing this at this early time(50 miles). I live in a wet state(washington) and built alot of engines(well in the 3 digits) and never experienced built up white condensation at a low mileage
