TC Diesel and timing belts in the oil bath

Hello all, I would like to order the new Transit Custom Titanium X L2. I am interested in the diesel with 170 hp. Drive for many years an Smax tdci 2.0 WA6 automatic with 140 hp. So far 370.000 km without problems. We drive every year about 10,000 km on the holiday with it. All 100,000 km the timing belt with water pump is changed very cost-effectively (automatic before 200,000 km was reduced to 100,000 km). Now I read here the new Eco Blue motor a tooth belt Here you would have to choose the correct oil in the oil selection, which is also ok. The effort would be much greater than with the dry system and the future maintenance really must be done by experienced mechanics. Probably best because of warranty always with Ford. Does someone also run the predecessor model for many years and can report what about it? Sometimes there should be resolution of the timing belt with wrong oil and with the 1.0 liter engines smaller car many Moto Also the oil increase by diesel which wanders into the oil during short distance would be a topic. The whole thing makes me very unsure as a long-time diesel driver. Also, the topic Ad Blue with which many manufacturers have a problem is on the screen. Since I am a frequent driver, I am more interested in diesel and possibly AWD. But I also read much more positive about the PHEV. I am very happy about information.
