Did my weekly check of the Octy yesterday morning before taking it for a long drive. It's done a total of 1200km.
Oil looked super clean and hadn't moved in level since I collected the car a month ago.
BUT
Found this oily smelling and oily feeling fluid inside the coolant reservoir, and all this scum floating on the top of the red coolant. Immediately panicked that the engine was blown - I've heard of water in the oil before, but never oil in the water.
Urgent call to Skoda service dude at the dealership and described it, and he assured me that if the temp gauge never moves (it sits on a dedicated 90degrees) and the coolant level (without the scum) was between the min & max markers, then it was completely safe to drive.
He described the scum as remnants of slight lubrication fluids left inside the cooling system when the car was manufactured, which has just mixed with the coolant and caused the sludge.
What he described sounds reasonable to me, but I just want to know if anyone else has encountered this before?
I've had previous engines rebuilt & refitted and never found that in my coolant.
It's due for it's complimentary 1500km inspection (it's not really a service) next weekend, so I've asked them to make sure they do a complete drain, flush & refill of my cooling system, which they've agreed to do.
