White stuff in my oil

Is this water in my oil? I just changed the oil less than 50 miles ago.

Re: White stuff in my oil

I've never seen coolant or water in the oil turn white but maybe it does in rare occasions?

Pretty sure that that is water. Either way, water or anti-freeze, I'm pretty sure it ain't s'pose to be there.

Re: White stuff in my oil

I had the same problem x100. started having problems and started to pull the motor down. Rocker covers were filled with a thick white grease like substance. My newly purchased so called re-co'd motor had a cracked crank. cracked head, HV oil pump and standard sump, and a heap of other problems. I'm told that a sign of water in all is the oil looks cloudy. a lot of water in oil is the oil looks milky. so a TON of oil in water must mean the oil turns to thick white grease. That's been my learning curve

Re: White stuff in my oil

I'm not seeing a lot of white, is the oil itself white? Is it just built up in the valve cover? Water will turn the oil white but the oil puddled in your rockers looks fine. Could it simply be condensation?

Re: White stuff in my oil

Does the truck sit out? We are in a high humidity locations both you and I. Even though it is like 15 degrees out right now I've seen this in several motors I had on some of my "toys" that rarely get use and sit more that they go. I always have such a fit to build the darn things then I drive them a couple of times[if that] and then I am through with then like an exgirlfriend or something that I had rather not deal with any more. One more question do you have one of those open breathers that go in the valve cover? I still think it is a tiny bit of moisture not of any doing of the trucks motor but of the weather around it. Unless your running it on alcohol then if you've got 50 miles on it your way clean and over due an oil change. Jim

Re: White stuff in my oil

I would guess condensation from blow-by? See it on pcv valves up here in cooler months frequently

Re: White stuff in my oil

Aluminum valve covers and intake, my guess is aluminum oxide (aluminum's version of rust) Don't know if it is damaging or not.

Re: White stuff in my oil

looks like condensation to me, caused by short trips in cold weather not getting the engine warmed up.

Re: White stuff in my oil

Condensation. Start letting your engine get up to temp before going anywhere on cold days. Gives the moisture a chance to cook off, and saves your bearings, the moisture will mix with the oil at idle, but if it cooks off before you put it under load, it will be ok. You can also try an oil heater at night to see if that prevents it.

I've seen that too from engines that sit for periods. Especially with aluminum valve covers

Re: White stuff in my oil

Looks like condensation. Let it sit for a couple of days, pull the oil plug slowly and see if u get any water before oil, If you do you've got head or gasket problems. You can also pull the spark plugs and turn it over and see if it pumps any water out of cylinders.

Re: White stuff in my oil

I agree it could be from short trips as well. It could also be from the PCV not working/hooked up right.

Re: White stuff in my oil

Drain your oil. If you see it in there, it's water/coolant.

Re: White stuff in my oil

Dont even need to drain the oil. Check the dip stick. If it looks like oil fire it up and let it run for a few minutes. Recheck the dipstick. If there is any white swirl on the dipstick or a milkshake then you have a problem. As others have said a little moisture this time of year is normal. I have some in my motor also and it gets up to temp for several miles each day and takes me to work each week.

Re: White stuff in my oil

It has been sitting. I bought it from a guy in Idaho that I'm fairly sure left it outside. Since I have had it, it sits in my shop which remains 40 degrees or higher depending if I'm out there or not. It does have the little breathers on each valve cover, so maybe it is just condensation. When I drained the oil to change it a few days ago the oil looked normal.

Re: White stuff in my oil

Only breathers, no PCV? That's your problem. If you need help on how to install one, just ask

http://autos.yahoo.com/maintain/repa...ques079_1.html

Quote:
The blowby vapors that end up in an engine's crankcase contain moisture as well as combustion byproducts and unburned fuel vapors. The crankcase is sealed to prevent the escape of these gases into the atmosphere, but the vapors must be removed to prevent oil contamination that leads to sludge formation. The positive crankcase ventilation (PCV) system siphons these vapors from the crankcase and routes them into the intake manifold so they can be reburned in the engine.

Re: White stuff in my oil

Be sure to leave one of the breathers (the crankcase needs to be able to suck in clean air).

Re: White stuff in my oil

Do you warm your truck up before draining the oil when you change it? That condensation can build up over time. I'd get the truck as warm as you can,go out and run the pizz out of it,then drain oil...carefully!
