Megane 1.5 DCi 110 knocking ?

[twerp 69]

2012 car with 70k

 

Drives lovely, FSH , new cambelt 1k ago but sounds terrible when cold and even when warm reving to 2300rpm sounds like knocking on top.

Never had one before, are they all rattly?

I would get the injectors checked first job maybe over or under fueling

These are quite easy to time up wrong if you don’t put the pin in the crank when doing the timing belt. 

Also not sure what kind of a noise it is but the tappets are a manual adjustment jobbie on these engines and rarely get checked and adjusted.

Arghh sounds complicated for all its worth 

 

Thanks

Oh and air in the clear fuel line by the primer bulb

Yeah, agreed /\ /\ /\ 

PITA job, there is no Key on the Crankshaft Timing Belt Pulley, so it moves as soon as you remove the Bottom Pulley Bolt to take the Cover off.  This is one Cam Belt you simply can't do without correct tools

Ok thanks - worth checking timing on Renault Clip scanner ?

What do you make of air in the fuel feed. I was wondering if that / leaking injector was responsible ?

Hi, not sure if Clip can read crank to cam synch, I've not had mine long and haven't used it in anger yet

is there a fuel primer bulb near filter ? I've had them cause air on 05 / 06 vintage
