So i recently performed an oil service and flush using a bottle of Liqui Moly oil flush and then refilled with 5w30 Liqui Moly LL01. Then I added a bottle of Ceratec. I have driven about 450 miles and decided to look under the cap and saw this (image below). Prior to this, i had never seen any residue like this. For the last 2 oil services, i was using Liqui Moly 5w40. The oil service before this recent one, i had added a can of Mos2.
The car is a 2000 BMW 528i, with an M52tu motor. It has 143k miles and i purchased it with 137k.
That whitish looking residue wasnt there before...
Is this a normal trait of Ceratec or am i seeing an issue that hasn't come about yet? Or is Ceratec even the issue here?
I have used Ceratec before, in my 2001 740i. But that engine didnt have a "plate" or covering inside the valve cover like this one. I was able to see the cam chains once i removed the oil filler cap.
