I'm a new member here,site seems great-hope someone can help.
I have a s40se 1.8 petrol,for the last 3 months the engine has been makeing a ticking noise,mainly when cold but also when warm(but not as loud).I've checked oil which is fine,am i worrying about nothing or could it be something more serious?
Thanks for your help in advance.;)

If you remove the oil filler cap does it look very clean in there or does it look sludgey?
It is also possible it might be the oil pan o-rings.

Thanks for your advice,i'll check it tomorrow and let you know.;)

I checked the oil and it was not sludgy,where are the oil pan-o rings?

You have to remove the oil pan to replace them.They are between the oil pan and the block.
