Contributor. 7 Answers. 4.2 s4 engines don't have a timing belt,It is a chain.The engine is mounted backwards,so they used a chain. Posted on Oct 18, 2010.
With that in mind, I'll swap out the chain and tensioners once I hit 150,000 miles, and install a 100psi oil pump and new water pump. The chain might make it to 200,000 miles, but I don't see any reason to push it until valve timing is no longer optimal. You also may need to break into the front end at any time after 150,000 miles to replace
S6 has a timing belt, no timing chain S6, A6 4.2 and the A8 are the same 4.2 block with the timing belt in the front. The newer gen 4.2 blocks use a timing chain in the rear of the block.
Audi allroad - Does only the allroad 4.2 use a timing chain - the '03 allroad brochure says that to fit the 4.2 in the allroad it has a chain instead of timing belt, and it was moved to the back of the engine. Sounds like a rather extreme change for one model. So does the A6 4.2 have a belt needing replacement while

The Audi 4.2 V8 engine is a robust and reliable motor but has suffered from timing chain problems. The timing chain in the Audi 4.2 V8 engine is responsible for synchronizing the crankshaft and camshafts, allowing them to work together to provide efficient operation of the valves. Timing Chain Replacement Options. If you own an Audi with a 4.2 The car developed a serious rattle which was obviously a broken timing chain tensioner. Have removed engine and gearbox (quite a lot of work) and found the usual broken tensioner but timing still OK. Most of the rest of the timing section looks fine, so probably against wise advice, am only going to replace worn or broken parts to save lots of uUrfQMi.
