The sludge shows that there is some water in the oil. Whilst it could mean that a leaking gasket is allowing water to get into the oil, it is much more likely to mean that you have been making a lot of short trips, so that water condensation has collected in the crankcase.
Thats exactly what i was going to say... 6 - 7 year ago i had a ford which would do this really bad around the oil filler, i remember when my dad drove it it use to clog up completely!! The cause short low rev trips... this is one reason why once the engine is up to operating temp one must take the revs high enough to allow the oil to circulate around the engine and evaporate any water, which can cause damage to the engine when its allowed to mix with piston by-products....
If water is getting into the oil, your water level will go down and it will also have turned into a black / brown colour due to oil contamination, and oil on the dipstick will also be white / black..... there are only a few ways oil can get into the oil, by either headgasket, cracked block or head, or a crack from the water channels on the turbo which is allowing water to get into the oil...
you will know when something wrong because of the 2 big givaways which i've mensioned, oil in your water and water contamination on the dipstick....
i hope this helps, give the car a real hard thrash, once fully warm of course this should then vaporise any water condense in your oil which will then be taken care of by the crankcase breather system..... which is connected to the intake, the engine then burns it with the rest of the garbage from the crankcase!
you can also check the crankcase breather system pipes as you may have a blocked pipe which is allowing the condense not to escape...
