Peugeot 106 1.5 Diesel - boris123
I have just bought a 1995 1.5 diesel (63000 mile) peugeot 106, towards the end of a 100 mile journey it developed a "knocking" noise- present when idling and running. Is this terminal?

well it dont sound good,are you sure its coming from the bottom of the engine (the noise) and not from say a loose alternator bracket?

Is this knocking noise related to engine rpm? Does it stop withe engine running and the clutch pressed down and held down? That would give some pointers.

Yes, it increases with rpm. It doesn't sop with the clutch pressed.

About 2/3 between min and max on dipstick.

I can't pinpoint the noise exactly othen then it's coming from the driver's side.

Unless this engine has been abused, it's unlikely to be a fundamental problem at this mileage. Looking under the vehicle on the RH side, locate the crankshaft pulley, held on with 4 13mm A/F bolts. Remove these bolts without slackening the alternator drive belt. The pulley and drive belt can now be removed. Don't touch the large central crankshaft bolt.

The engine can now be run in this condition, gently and for short periods. It will be lacking its torsional vibration damper, alternator drive and alternator belt idler. Any of these components can cause the noise; the belt and the idler are most likely, but check the rubber in the TV damper. The pulley can be refitted easily without slackening the belt adjuster, although the belt needs to be set pretty tight, so that it pings.

The RH engine mount is also a favourite - near the coolant header tank with a white or orange plastic top. The orange ones are suspect. Observe where the aluminium engine bearer disappears into the underside of the mounting. Press down fairly hard on the engine (not on the belt cover) and check that the bearer moves down without hitting the chassis. If it doesn't, the mount needs changing. (easy, but a bit expensive).

First thoughts only, please report back.
