Early piston slap?

[12dan34]

Hi people, please can you have a listen to the video attached. This is my 1998 c2, i spent £4.5k on an engine rebuild after the ims started to break up (caught in time luckily), then a couple of months later it starts making this noise when starting from cold. In the video it hasn't been started for 3 days and as you can hear the noise goes away after less than a minute. The indy has told me it's early piston slap and will cost about £6k to put right!

It didn't do it before and i wonder if they've put different oil in it or something. Any ideas please?

Thank you.

It certainly doesn't get worse under load. It has Mobil right now but I've read elsewhere that it's not the best so I'll try that nano one in the next couple of weeks.

I have since read that changing to one of these other oils can cure it completely and significantly reduce all noise on startup which can only be a good thing.

Thanks for looking guys.
