Not sure if this has been discussed, Ford using an oil-immersed timing belt!

It seems VW has been on to this too:

Question is? Change intervals same? Cost more to change? Those are the important questions. I like timing chains.. No changing necessary..i like!!

It's suposed to have the same service life as a chain. Here's a more detailed look:

And what do they consider a chain "life" this days? 200k? 300k?
Fiat 1.4 Multi-Air engines go 152k miles per manual on their belt.

I always thought that say 100,000 miles or so would be time to change a chain. As everthing does wear and tensioners stop doing their work. Ok some engines do 200k or more!

Honda's GCV160 uses an oil-immersed timing belt as well. It seems to be proven, at least in concept.

A friend had an oil lubricated timing belt on his Ford Pinto and that was more than twenty years ago.

Interesting article about the change in glass reinforcement. That probably explains why my 89 Accord took TB durability from 60K to 90K miles in the late 80's.

My Ford 4.6 had a very long chain and was still quite at 218K. Many 4.6 engines have well over 300-400K with no chain problems.

Yeah, but that wasn't by design!

That was in the 60's and 70's.
