How do,
Just about to service my 318is and was wondering how crucial is it to torque the plugs up the correct amount. Obviously i don't want to strip the threads but what are the consequences of them being a bit looser than recommended?
I also want to replace this hose.
How do I get to it? Do I need to take the intake maniflod off?
Cheers

yes, you need to take the inlet manifold off. its a fairly long pipe, that has a metal pipe running through it. bit of pain in the 4rse to do, but nothing too demanding...
re: the spark plugs, i just wind them in until they're tight! you'll have to be very stupid or very strong to make chocolate of a BMW head...

This is the picture on the back of an NGK plug packet if thats any help. Sorry it's really dark :s
Basically the plugs need to be wound in until hand tight then: If the plug has a conical seat it needs to be turned another 5/16th of a turn, If it has a crush washer it needs to be turned 1/2 to 2/3rds of a turn.

I normally put a bit of threadlock on the threads before fitting, Special stuff called chemical metal...... Works a treat

No need to ensure you have the correct plugs either!
