I agree Mark.
The 2.2 is perhaps the best engine design Vauxhalls have made to date and was designed as the first truly global engine, youve only got to read the american forums to realise this motor is a big hit in USA, and over there theyve even got the bhp turned down a bit as standard.
Once a 2.2 that actually needs the chain mod is done and correct size oil nozzle as used from 2002 the timing chain should be good for over 100,000 miles.
So folks lets stop panicking and realise that we dont have to worry about cam belts snapping every 20,000 miles like most. 😃
