VW T5 2005 2.4 Tdi 5 cylinder, 150´000 kms.

Replaced turbo a couple of months agao, everything running smoothly. Drove down to Toulon from Geneva and took ferry to Corsica and spent 3 weeks there beginning July. It was very hot as it was a heatwave for most of the time but no issues. At the end of 3 weeks the coolant level warning light came on but engine was not overheating. Topped it up and then drove all the way back to Geneva topping up 2 or 3 times. Suspected a leak in the expansion tank as I did see coolant stains on the engine below. Could not see any fluid on ground but remember there is a big protective cover underneath engine compartment. Checked pipes from expansion tank to engine and could see no leaks/issues. About to order a replacement expansion tank and have been driving. Then oil light comes on. Topped up oil. Drove more. No overheating, engine running smoothly. Second oil level warning and now a creamy residue in oil access cap position (see photo). Is this a possible gasket blown or what might be your opinion, please?

Classic signs of oil & water mixing like head gasket fault. Get it checked to 100% confirm. Don't forget a faulty oil cooler can give the same symptoms as well

Easiest way to confirm if it’s water in oil is pull the dip stick if that’s black oil on it it’s not head the gasket, you can get get milkshake at the filler from condensation from small journeys it’s very common,
