one of the guys at work recently bought a megane tin top convertable thingy with the 1.9 deisel engine in it
now, a fe months down the line, it shuddered to a halt after it had one of the return fuel pipes changed
investigations afterwards tend to point to the diesel pump in the stages of packing up as it's shredded the timing belt and is leaking from the rear
so the belts been stripped off, but we don't know if the belt has jumped or if he's bent any valves in the process

the questions then, all answers need to be seperate because of various stages of the engine being fucked or not

how much is a pump calibration, assuming it can be repaired?
how much is a new pump (£500 is what renualt are charging) if it can't?
how much to change the belt?
how much to change some valves (depending on if any are bent in the first place?) figuring that this will be a head gasket change job?

the garage is going to put a new belt on (after first saying that they didn't have the corect locking keys for the engine, does it need them?) and run it up to see how much damage there may be potentially before getting the leaky pump sorted

any ideas?
is this a known fault?
engine/car is just over 3 years old

thankyouplease

 

sounds cheap for a pump...

has the engine had any petrol in it?

 

Oh renualt diesels do this for a past time, used to be my favorite, job!

dti or dci?

you don't *need* the timing tools but if you've not done one before it's certianly advisable. The only timing tool is a crank locking pin which is actually a load of shit, i never bothered using it as it was more trouble than it was worth. the way it works is the new belt will come with 3 white lines on it, each white line lines up with a notch on each pulley. Be warned theres about 6 different belts listed for the 1.9d so order it by vin number/engine number if possible. all six belts are also almost identical aswell with only mm difference in teeth pitch, if you fit the wrong one eventually it will snap.

valves will almost certianly be bent, it's not too un common for it to damage the guides aswell.

how do you know the belt was to blame? worn aux. belt tensioners and alternators causing the aux belt to eat it'self then through the cam belt off is the most common one i have seen!

 

renault diesel

 

My Mates 1.9 Megane Kept Shredding Fan Belts, chewed 3 of em, had a new AUX tensioner to.

the diesel pump was leaking form the rear and he was off to someone to get it fixed when it went pop

intresting to know baout th ebelt, he's got one and they are having difficulty fitting it, could be the reason

 

Something else i forgot to mention is they almost always shear the keyway on the cam pulley. which makes it a right pain to re-time if you haven't already checked.
