That means water/moisture is in the lubricating system. A very common reason for this is the vehicle is not driven long enough to be hot enough to evaporate naturally occurring condensation. If you don't drive the vehicle alot and/or short trips . a good solution may be to switch to synthetic oil.

Dont panic. The creamy deposits youve found is where water/moisture is mixing with your engine oil. This can be due to any manner of reasons. Firstly, oil change intervals are always increasing which is not necessarily a good thing as it puts even higher demands on the oil between changes. If most of your journeys are local/town trips, this makes the problem worse as your engine simply isnt running as its designed to at varied speeds, up and down motorways and the like. Is your cooling system thermostat working correctly? This is a very important component in any engine, as its function is to maintain a constant working temperature. If your temperature gauge fails to read a normal working temp, it could be your thermostat has become stuck open? What this means is your motor wont be running hot enough, which will in turn develop cold spots and condensation around your engine, hence the cream sludge. Give your engine a good quality engine flush prior to changing the oil and filter. Top tip, dont go for a cheep grade oil to try and save a few pounds, in the long term its uneconomic. Many engines these days are turbo charged and bearing failure due to poor quality oil is a very expensive lesson to learn by, I can assure you of that. One other thing to check is your coolant level, has it dropped at all? There is a slim possibility there may be cross contamination between the two fluids, possibly due to a cylinder head/gasket fault. Is there a lot of pressure when you remove the coolant expansion tank cap? if not, your probably in the clear. I hope this advice is of some help? Good luck.

Why does my frontera smell like a chip pan and no im not on bio diesel

Sounds like the cylinder head gasket is on its way out or an oil feed pipe is gunged up.
Remove the oil filler cap and check for a light brown cream like substance if this is present then the head gasket is leaking (also can smell like chip oil).
If its not have the oil feed pipes checked as this can cause the same smell.
I would also check the exhaust for leaks as a precaution.

have a coolant pressure test done and if you are not holding pressure there is a possibility of a leak in the housing behind the water pump
dew and gunk in the breather are indicators of water in the oil

Peugot 106 got warter under rocker cover and white creamey gung going from the breather from the rocker to the air filtter been told its not head gasket

So it's not the head gasket? And you are still losing coolant? Well, okay, you will have to find how the water is getting into the rocker, and whether it's your lost coolant or plain water. IDK, possibly an intake manifold leak?
Even though the oil looks clean, the water and gunge in the rocker area will drain into the sump and contaminate the oil. If it's not the coolant, run the engine until it is hot, then give it a few minutes for the oil and water to drain down from top of the engine into the oil sump. Then change the oil and oil filter. Good luck, hope you find the problem.

Do you notice a puddle under the car? Or smoking when you shut it off? The rocker cover gaskets are the culprit. If you have the spark plugs in a well inside the rocker cover, the will fill up with oil and also leak out the back. You can replace the gaskets, a fairly easy job, you have to pull everything off the top of the engine to get the covers off. And they give you the new seals for the spark plug well with the gasket kit. They only go about 10 years, I replaced mine and they are starting to leak again. Hope this helps.
