Japanese vehicle engine replacement.

Hi,

Are the engines of automobiles in Japan routinely replaced when the vehicle has amassed a certain amount of miles? A friend of mine stated that the engines are replaced when the vehicle has accumulated 100,000 miles (which IMHO, is not an extreme amount of miles for those types of engines).

He said it had something to do with 'environmental regulations'. Any Dopers out there know anything about this?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
