how do you replace a cigarette lighter in a Vauxhall Astra
You don't say what year your motor is,but assuming this is the Z22SE engine,it will have a chain.(Check engine options in owner's handbook)Don't think there are any variations on 2.2 petrols,so you should be ok.
There is no set replacement interval. It should be replaced when it becomes noisy. Failure to maintain the correct oil level, change the oil at recommended intervals or use the correct grade of oil can dramatically reduce the life of the chain.
It has a chain that requires no maintenance.
The 3.8 L - V6 engine has 1 timing chain
2013 Hyundai Elantra SE Coupe 1.8 L engine has a chain.
it has a timing belt
No, it has a chain. long Chain with Hydraulic (problematic) Tensioners
Burning oil-No relation. Leaking oil on hot surfaces because of incorrectly installion of gaskets-yes.
If it's Z20LET then yes it has a cam-belt as opposed to a chain and think recommend changing every 36000 miles or so
