Milky Oil..... :mad:

Well here I go. 2006 wrangler 136k miles showing signs of moisture in the oil. Pulled the dipstick out since last oil change 1000 miles ago and noticed a bead of white on the stick. After redipping the stick there was no sign of moisture and the color of the oil appeared normal. Also under the fill cap there were some clear beads of moisture on the cap and few looking down into the hole. I'm scared for my beloved jeep lol. If anyone has any direction of where to start to diagnose I would greatly appreciate any info. Oh and the coolant level is lower then I thought is was last time I checked. Hopefully the signs don't point in the direction I think they do. Thanks!

What year is your TJ? From the sounds of it, sounds like you could possible have a cracked head which is allowing a little bit of coolant to mix with your oil.

Well lets not assume the worst.

If indeed you have an appreciable amount of water/coolant in the oil, the crankcase oil going to start looking milky, not just a like on the dipstick.

With regards to the cap, how long are you driving the vehicle? In the winter it is expected that there will be internal condensation. If you do not drive it enough, long enough to get hot the moisture may accumulate. This moisture is not a problem

I only have a 6 mile to commute to work round trip for a total of 12 minutes a day 5 days a week. I also warm it up before I drive. I also have a misfire in cylinder 4 which I believe is a leaky injector.

Put some gasket sealer/sweller into the oil.
If it's a leaky head gasket, this may help...
4-5 bucks at Walmart

Check your PCV valve for proper operation (pull it out and see if it does not rattle (bad) or rattles too easily (bad - it is spring loaded). Other than recirculating oil vapors back into the intake to be burned, it also removes moisture from the crankcase as you drive. My '00 Ford Expedition had this issue and I figured a cracked head, but I found the PCV valve hanging in space and that fixed it.

Those are short trips, especially when it is colder out...I bet it is condensation.

Replaced PCV yesterday and will check oil and stuff in a few days to see if the condensation went away. It was clogged up a bit so hopefully that was all it was.

I seem to remember that little bit of milky issue was caused by a cold engine and used to be called cold water sludge. If you have a lot then usually the oil on the dip stick will have some milky look. I once had a `963 283 Chevy and during an oil change it never seems to stop draining, milky streak in the oil draining. The result was a pulled head gasket. If you have a nice city bypass or similar road trip 10 to 15 miles or so do that trip maybe once a week to get the engine nice and warmed up and some of that condensation evaporated out. My self I generally don't let an engine idle much to warm up. It will warm faster under driving load and the sooner it gets to operation temperature the less blow by past the piston rings.
