Kangoo Distribution 1.9 Diesel Motor F8Q

Good afternoon, the distribution has changed 20,000 kl, in the workshop, it has a noise like rooding in the upper part I think it is on the pulley that is on the side of the rocker lid, sounds there are no one if they changed the tensioning water pump etc., as I can change that bearing, good as a disassembly and amount the distribution a greeting.

hello already disassembled?
The first thing you should do is get the Sigual pulley I think it is a key 15, then take out the service straps, the covers that cover the distribution ... and tell me that you see ok
