I have just purchased a 3 door Astra Sport 1.6 16v Ecotech, so I have just had its 60k service carried out - (new cam belt and tensioners, full oil change / engine flush, new plugs and filters etc)
Before it went for its service I noticed that the lifters were quite noisey and assumed that an oil change and flush should do the trick. The car was owned by a female colleague of mine before hand who didn't really drive the car at all hard (never exceeded 3500 rpm) but the quality of the oil she used was questionable.
My garage tells me that the noise should die down once the new oil has settled into the lifters and have advised me to drive a few hundred miles and then return it to them should the noise continue. Is this correct? is this safe to do? If I need new lifters then where is best to get them / should i need to replace the cams as well? Any recommended upgrades?
as above all vauxhall engines are well known for sticking lifters. you will find once the engine warms up the oils gets thinner, the tapping noise will stop. theirs been quite a few post's on this subject and people swear by taking out the tappets and give them a good cleaning and soaking them in warm oil. cleaning them gets rid of all the crap thats making the lifters stick, or you could fork out £180 for a full set of tappets from your vaux dealer.
Thanks for replying. I have been running the car around all week and the noise keeps coming and going. I noticed that on start up the car has low oil pressure and the light stays on for anything up to 15 secs.
At first I thought... oil pressure switch? so had a new one fitted, no joy there either. I am thinking maybe the noise is caused by insufficient oil pressure at the top end, but there seems to be plenty of clean oil around the cams.
I dont mind spending out on new lifters but want to get the oil pressure sorted first. I presume if it was bottom end it would be knocking and clunking, which it isn't.
