NYrobbie77 Posted December 10, 2011 Report Share Posted December 10, 2011 was checking the oil as it has a slight leak. usually will only be down about a quart per 3000 miles. this gooey milky stuff was all the way up the dip stick and the tube. my first guess would be coolant is getting in the oil. i don't have any symptoms tho, no smell/smoke from tailpipe, doesn't seem to be using any coolant. the coolant does look pretty gross in the overflow tank. i took the cap off the oil fill and its clean as well as looking at the top of the cam area. cars got 201k miles, '98 V70 GLT LPT auto. thanks all Link to comment Share on other sites More sharing options...
Keep Calm Chive On Posted December 10, 2011 Report Share Posted December 10, 2011 If you dont drive your car long distances letting the car fully warm up this can happen. There is moisture in your oil system and unless the motor is run long enough to heat up and evaporate it you get this l milky shit on your dip stick. I had this once over the winter and it was because my car would sit in my brothers garage and unless the roads were clean I would only have it idle in the driveway. After I noticed it I decided to either let the car idle longer (to properly heat up) or just take it for a short drive around the block after it was warm. Its just oil froth Link to comment Share on other sites More sharing options...
Keaton85 Posted December 10, 2011 Report Share Posted December 10, 2011 PCV, thermostat, a lot of 5 minute drives.... Link to comment Share on other sites More sharing options...
SeedyRom Posted December 10, 2011 Report Share Posted December 10, 2011 Mine got that way too during wet seasons. Ended up being the dipstick tube seal at the block. It will let rain water and snow into the tube and get it all milky like that. Check your coolant reservoir to be sure there's no oil mixing to be safe.

NYrobbie77 Posted December 10, 2011 Author Report Share Posted December 10, 2011 lets hope its the moisture buildup. my drive to school is about 14 miles each way, mixed highway and side roads. if the better half takes it to work, its only a 2 mile trip each way, definately not giving it enough time to warm up fully and burn off all the moisture. the coolant resevoir is kind of nasty. can't really tell if the fluid was red or green in its good days. its kind of a dirty pond water looking stuff. will try to take a pic of it Link to comment Share on other sites More sharing options...

Gilhuly Posted December 19, 2011 Report Share Posted December 19, 2011 Why don't youy try to change your coolant instead? I wouldn't worry about the cheese. It's a very common cool weather observation. lets hope its the moisture buildup. my drive to school is about 14 miles each way, mixed highway and side roads. if the better half takes it to work, its only a 2 mile trip each way, definately not giving it enough time to warm up fully and burn off all the moisture. the coolant resevoir is kind of nasty. can't really tell if the fluid was red or green in its good days. its kind of a dirty pond water looking stuff. will try to take a pic of it Link to comment Share on other sites More sharing options...
