Why does my Vauxhall Astra Estate ratting during start up?
My Vauxhall Astra Estate (1.6 petrol with 200k on the clock) has developed a heavy rattle/knocking noise. It last for a second or two at the start up. Sounds like it's in the head/VVT area. Always flushed engine with oil changes, but I'm guessing either the oil is draining back completely while the engine is not running or blocked/defective VVT gear. Does either sound correct to you?

Could also be that the oil filter does not have a non return valve. Best only to buy OEM or known brand oil filters. But at 200k you can expect some engine wear.

At low revs there is the sound of slight vibration type noise, less so with the windows closed.
