Also, what Year is the escort ? -javman01 Yes
Ford suggests 60,000 miles
yes they have a belt because ford stopped making chains in 1997 with the escort I have a Mk 6 55 plate t280 and that has a cam chain
Cambelt.

Allow 2 hours which includes removal and refitting cambelt. Best to renew cambelt at the same time so budget for belts and followers.
Ideal time to change cambelt is 60000miles, so if you're talking 100000km, you're OK, if you're talking 100000miles, get it done yesterday
The E46 uses a timing chain. The last time a cambelt was used in a 3-series was for the E30. The carbureted 316, the 318is, and the M3 used a timing chain.
