Timing belt in oil

[JHZR2]

At least they went back to chains in the new I3's, so they learned.

Yet another one of those retorts you can use when someone says 'I trust the engineers that designed my car they know what's best'.

As if they're infallible.

Too bad chains wear and break too.

Design flaw. As the belt wears chunks of rubber fall off which clogs the oil pump screen and kills the engine. Unlike a dry belt there is no way to check a wet belt for wear.

Chains break because of long OCI's, poor design and/or poor materials. Some MB engines need a new set of chains every 100k miles. To me that's ridiculous.

I guess the chains innmy MB cars didn’t get the memo.

But to think that chains don’t have issues, even with good design and good upkeep, is playing ostrich imo.

I think VW has an engine with an oil bathed timing belt as well. Maintenance interval is supposed to be 150k. Personally I refuse to buy any engine with a timing belt at this point, too many chain options out there.

The EA211 uses a belt but it isn't a wet belt design. Those are known to go 200K+ without issue. I feel better having a belt vs. chain in our VW as they don't seem to have chains ironed out yet.
