Good afternoon all just wondered if anyone could let me know when the recommended time is for adjusting the Tappets. My engine has done around 50k miles.

Thanks in advance,

Paul

The engine was totally rebuilt by Alpina 10 years ago so assume that it's got Alpina cam in

It shows that the part number for the Camshaft is 11 31 1 287 606 and also managed to get some info from Alpina saying that the Exhaust and inlet are 0,25 set on a cold engine.

I contacted Alpina and they sent me a spec sheet and it says valve clearance is 0,25mm for both the exhaust and inlet. Is there no way of replacing the injectors with quieter ones?

2. Go to: MANAGE ATTACHMENTS underneath the test field
3. source your file and
4. upload it.

You might get an error if an extension is not permitted (*.bin is not allowed) change it to .zip and tell us to rename it to whatever it was assume .pdf or .jpg. Or simply zip it.

Otherwise you can send it to me. e-mail address is send by PM. so I can upload it for everyone here.
