Hi,
I've got a Vauxhall Corsa 1.4 (8-valve). When it's cold weather the tappets rattle REALLY badly when you first start it up after it's been standing for a couple of hours.
When I asked about this at the garage I was told it was the hydraulic tappets getting old (~80k miles)...I've got to admit to being sceptical and wondered if anyone had experienced similar and knew how to fix it?
Cheers, James
