Hi,

My 1st Gen Mini Cooper S has an occasional habit of sounding really quite tappety on the first start. What's odd, is no matter how long the engine has been running once I first start (as short as a few seconds), a turn off and a 2nd start completely clears it. Once it's cleared, it generally doesn't happen again until the car has been resting for a few days. It sounds like oil starvation making the tappets noisy, but I don't know these engines well enough to know what is what.

I've taken a video of it below. Any ideas?

Probably the tensioner, mine did it when the engine was cold started.

Thanks for the quick reply, is the tensioner on the drivers side of the head? That's where the sound seems loudest?

I think so yes, not sure how much the part was as I always extended the warranty, however it wasn't a big job to do apparently, and it's quite a common fault.

My R53 has exactly the same fault. I had the tensioner changed and it seemed to help for a while but every now and again it comes back. As long as you make sure the tensioner has been changed and the car always has enough oil then it really isn't anything to worry about.
My MINI has a new noise everyday but I like to call it CHARACTER!!
