When I start up, mainly from cold, I get more of a Diesel noise from the Engine. Its not a chain noise and sorts itself out after about 3-4 seconds, almost like its waiting for the oil to get somewhere? I first noticed it after my new head and and Oil scraper ring replacement. Then the monkeys at VX put it all back together all wrong and I ended up getting a hole new lump out of them under warranty. The new lump did it a little but only on the rarest of occasion. I did a service with an oil flush and filled up with VX Super Synthetic long life. After the oil change this is happening more and more. Could this be related? Any ideas guys? Car runs fine, no smoke, emissions are spot on after MOT so everything looks healthy, but the noise is still there. notsure.gif
