I did an oil change today and noticed the grey oily sludge on the oil filler cap and inside the crankcase exhaust breather tube. I also found a small pool of water sitting in the top of the oil fill tube.
Could this just be a result of all the bad weather lately?
If it is something worse, what could it be?
The oil was good and black, with some tiny metal filings in it - not much, but a little bit. I've been changing it very regularly to try and get as much contamination out as possible. I've even covered the bottom of the sump plate with magnets to trap the metal particles - which worked pretty well.
I noticed some water drip out of the oil bath when I upended it as well.
Any ideas?
