I noticed this morning a rattle/knock when revved from my 1.4 K-series (8 valve)
Sounds like it is coming from the camshaft.
The noises goes when the engine warms up.
I am using 10w/40 GTX Magnetec for modern engines.
Is this noise normal, or should I start worrying?

Hi Doc,
No disrespect to Castrol, but we have seen several cases of valve lifter problems on K-series with this oil. Suggest you introduce a flushing agent, then change oil and filter using either Texaco 10w/40 or Vauxhall 10w/40 semi-synthetic, and consider adding Forté Top End Treatment (call Forté on 024 7647 4069 to find nearest stockist)as this often cures problems with tired hydraulic valve lifters.
Regards, Adam
Whatever is rightly done, however humble, is noble.

Thanks for your input Adam.
I must admit I have only noticed the noise since an oil change a couple of weeks ago.
Before I was using 10w/40 Unipart part synthetic with no problems.
I always use a Rover premium filter (GFE 26)

Piston Slap.......which is nothing to worry about.
As it disappears when warm, that confirms it.
