Could anyone please advise........
Was driving back from work to day and realised when i put my foot down i was geting lke a tapping noise from engine bay, i thought it could be the outlet manifold gasket at first but when i got home i looked in engine bay .
i gave some revs from throttle cable and could hear that the tapping noise was coming directly from thefront left corner of the cam cover (closest to front crank shaft)... I have only had the cally for about 3 weeks and havent done nothing to it .. could it need oil change as i was supposed to get round to it and could anyone tell me wether i should get cam belt changed aswel or is there an tell tales for when its due for a change. Is this tapping life threatening for the engine and is it an xpensive job?

ecotechs are bad for breaking exhaust manifold studs the bottom one next to the thermostat and sometimes the one above it and as davfly says the gasket blows sounds pretty rough almost like a ticking noise
So if i have the cambelt changed does it mean i have to have the water pump replaced aswel ??? also if the bolt is broken how will i e able to take it out, is there any engine flush liqid i may be abl to use with oil change....
Yup davefly was right i took off the manifold heat shield and the top bolt clsest to crank was not there so now the problem is found what would be the best way to resolve it without stripping head off ... is there any good pros out therethat know how to do this please???
well, when I asked vauxhall how much for a manifold gasket change, they automatically built in the price of a mobile engineer to come out to drill out the stud & repair it etc - turns out that alone was about £120! - but a lot of that was travelling time (20 mile round trip)
the problem is that getting studs out is a black art - an extractor is more than likely to break off in the stud - which then doubles your problem as it's then hard to drill it out squarely.
what I would do it drop the PAS pump out the way, and go straight to drilling it out - and not risk an extractor in the first place - then I'd helicoil it (probably do the other stud as well)
-or- if you have any local engineers who'll (a) come out and do it for a reasonable price & (b) will actually touch the job with a barge pole - then I'd leave it to them.
thanks gary but i think i would prefer to have pro sort it for me as i have never done this sort of thing before so if any one knows someone who can do it and are in my part of the world i would greatly appriciate it ..
