chain tensioner

Does anyone have the part number for the e36 chain tensioner upgrade? Is it tricky to change?

Thanks in advance.

Search in the e24 site. It has the part number and how to with nice pics. I just did the upgrade. Not bad ... a little tight but a 20 min job.

Thanks Mike, thats just the ticket.
Think I need to open the wallet and change the spark plug wores as well!
