    Default hydraulic tappets?

    iv started getting a tapping noise which used to happen to my old astra when it was running low on oil,more oil used to help the problem,so today on my 1.8sri 55 plate i tried the same after topping the oil up (i have to say it was pretty low!!!) and after a 20 mile drive problem persists is it possible that a longer drive may be needed?? my friend seems to think it may be the hydraulic tappets and an oil filter change along with some quality oil may help any ideas??

    change the filter... leave the old oil in but top it up to about half way up the dipstick... throw some good quality flush in and follow the instructions.... then do a full oil/filter change with some quality oil.

    Post a sound file of the engine on here, would be better to hear the noise.

    If it is a VVT it is possile the Cam Phaser solenoids are starting to fail, normally get a rattle on start up. I did a How 2 on removing the solenoids to take the filters off. If the car hasnt had a good service history then the filters may be blocked.

    For a 20 minute job, they are worth checking.

    I would also recommend an engine flush and refill with the right grade oil.
