Us being Audi owners, reliability doesn’t come to mind, but what’s the most reliable and the most unreliable Audi engines? 4.2 V8 is a son of a bitch Edit: B6 The TDI 4.2 has a stroke-to-bore ratio of 1:15 meaning the stroke is 15% longer than the bore is wide. In comparison the 370hp V8 Yanmar 8LV-370 has a stroke-to-bore ratio of 1:11. The downside of a long stroke is greater piston speed resulting in increased friction. However this problem only comes into force at engine speeds well above 5 The 4.0 has a rather sophisticated version and hopefully this new Audi system will keep too many carbon deposits from forming. Our 4.0's have large oil droplet accumulation and small oil droplet accumulation mechanisms. The old 4.2L V8, in the RS4 e.g., was notorious for carbon deposits as early as 10,000 miles! Ack! 1) Mercedes M113 Rear Main Seal Leaks. Up first is a problem that’s very much related to the age and mileage of most 4.3, 5.0, and 5.4L Mercedes V8 engines.

Zero compression on one cylinder - 4.2 V8. Worth saving? I have a b7 S4 with the 4.2 in it. Car started misfiring while I was driving, turned it off when I stopped, and she did not turn back on.

The first-generation Audi RS5s arrived on U.S. shores for the 2013 model year. Back then, they came in coupe and convertible form and had a brawny V8 stuffed under the hood.

I've owned mine for 3 + years now, bought it when it had 50k miles on the clock and it now sits at 120k miles. Mine's a 09 6mt. I had no idea about the reliability issues coming in, but I must say I've been pleasantly surprised with how reliable she's been, and I daily drive it too. One that can make just about any big-displacement V-8 perform like a hero.
