Dear forum… We thought with a few people earlier about what the following repairs could cost in a proper, free workshop. Ggf has already experienced here. The assumed car is a Mini Cooper from 2014 with 100,000 km and the N16, 122 hp petrol engine, 6-speed manual transmission: 1) Exchange of the chain tensioner 2) Exchange of the entire chain with rails and tensioner… 3) Exchange of the valve cover seal 4) Exchange of the cylinder head seal 5) Exchange of the oil tank seal A buddy works at VW, the others only have their experience of some components and are also not motorists. I also have no idea. The workshop would have to create a calculation and thus want to mention only approximate values from the belly without guarantee: So we came from 1-5 to the following numbers: 1= 250 Euro 2= 1300 Euro 3= 100 Euro 4= 1300 Euro 5= 350 Euro with oil What do you think? On 100 Euro you can certainly not say it. But could these numbers fit about? I am happy about your E Thank you.
