corsa tappets

Hydraulic tappets will rattle/tap when they are being starved of oil.
Has your oil and filter been changed recently with the correct SYNTHETIC oil ?
Have you checked your Camshaft/s for wear on the lobes.
Are you sure the rattle/tap is from the tappets ? Could it be from the timing chain.

sounds ok to me!Nige F said:My Daughter in Law`s got one- Rattles too...Hydraulic Tappets....Have to live with itThey all do it.
I remember the sound of tappets so fairly sure and i dont suppose its had an oil change for yonks--its an easier job than tappets though and i am doing it cos shes a nice ole dear-so maybe i'll start there. thanxjonnyfishing said:Hydraulic tappets will rattle/tap when they are being starved of oil.

on all modern petrol vaux's they have hydraulic valve lifters, i had touble with my girlfriends 2.0 16v ecotec i found wynns engine flush followed by a good quality semi synthetic oil 10w 40 change worked wonders. they all sound a bit tappety till they warm up.
also this may sound stupid but i also found that a noise i thought was tappets actually turned out to be a leaking exhaust manifold gasket might be worth investing a tenner in one

is this corsa diesel? if so i can remember somthing about these tappets can be adjusted, they are shimmed. a little trickey process and also vauxhall recommend a special oil (Titan) if i remember right i hope this helps
