Don’t let the Audi 4.2 timing chains bite.

Plastic timing chain guides = weight savings

“Moving the timing chains to the back side of the engine....”
Means more billable hours for VAG dealers worldwide

As an aside, I think the numbers bear me out— the “most reliable” of the Audi 4.2s was actually the ABZ designed in the early 1990s . All downhill from there.

I’m a big fan of weight savings choices at the expense of durability on street cars that save less weight than, like, the driver e ating a smaller lunch.

Try and look up pictures of the timing gear set used in the V10 TDI for the touraeq, keep a towel handy.

Timing chains on back of engine = because fuck you, that’s why

It looks like a clock.

At least they’re gears, that should be relatively simpl...
Oh, Jesus Christ VW.
keep a towel handy .
Nope. “Making things way more complicated than they need to be” is not good engineering. Even if it is the way the Germans tend to do it.
I swear the engineering mindset over there is “let’s design in as many potential failure modes as we can think of and still make it work.” Oh, and “let’s use a screw head nobody has ever seen before.”

do those fail prematurely?

My example was a Honda so I doubt that it would fail.

rather common on ‘70s-80s Japanese motorcycles. IIRC it let them make the engine narrower due to not needing a discrete timing chaincase/cover.

that would definitely give me nightmares!
