    Default Laguna 2.2dci timing belt replacement

    Hi Guys, Haven't been on here for a while (I guess that's a good thing as no problems, right?) Anyway got the timing belt replaced and now the engine sounds like a .50 Cal machine gun! Rang the guys and they say timing belt can take time to run in. Apparently with a timing belt it is either right or the engine will not run. Has anyone else noticed major changes in noise or performance after a timing belt replacement?

    I would say that something is not right. I think you need to take it back to them.

    Hi Col, They said give it a week and if engine hasn't settled down then take it back. They are Euro specialist and do timing belts all day. He explained that engine will not run if anything was wrong. Noise is coming from injectors/detonation however injectors have sophisticated warning and control systems. I know this from previous experience when high pressure fuel line bolt came loose and diesel poured out and computer warned injector fault.

    I suppose all you can do is what they say, hope it settles down.

    Am starting to think the problem is in the exhaust. In order to perform timing belt replacement engine must be jacked. Moving the engine like this may have damaged/loosened the exhaust manifold as that is area where all the noise is coming from. Lets see how helpful these people are....

    If you have an exhaust leak like you suspect you should be able to put your hand around where you think the leak is and feel the exhaust gases. I find this is best done when the car is cold because its easier to feel the leak and also less chance of burning yourslef.

    Good luck with it and hope they come to the party.

    noise like a machine gun ,if the belt is too tight it will whine ,too loose it will slap on the cover ,cant see the noise going away ,if it sounds like a machine gun ,have you had it back to them to listen to it or are you talking to you over the phone ,i would be taking it back to them and having a mechanic listen to it ,not someone at reception ,PUGS

    A piece of hose (any size) held to your ear & poked around like a stethescope will soon locate exactly where the problem lies!!

    Thanks for all your response. My car sounds similar to this now DIESEL V12 GERMAN WW11 TIGER TANK ENGINE RUNNING OPEN PIPES - YouTube When I picked car up I confronted them about engine noise. They say is a bit loud now but they add car was loud before timing belt replace! They say newer diesel cars are quieter now and mine is older (2007) so is more noisy. I have looked under car and took plastic cover off, bolt falls out, it is one of the timing cover bolts!!!!! Will be talking turkey with them first thing in morning....

    Forgot to mention car has also lost performance due to reduced turbo boost. Especially off the mark car is very sluggish then finally boost kicks in. It's all related, engine/exhaust noise, reduced turbo boost. All this from a timing belt replacement!!! Car was running perfect before....

    Your description sounds like an exhaust leak somewhere, if you are losing boost maybe between the head and the turbo

    Looks like they have not paid attention to detail when doing the belt change. If they don't fix your problem looks like you will need to go to the Department of Fair Trading NSW Fair Trading - home

    G'day Col, That's what I suspect has happened. In order to replace timing belt engine must be jacked to get proper access, something has gone wrong and exhaust manifold has sustained some damage. The situation would then be salvageable even if I must go elsewhere to sort this sh$t out. However if the timing is out then valves might be sustaining damage however my understanding is ECU would pick this up and shut down engine or at least flag warning. This is why people buy new cars so they don't have to put up with this sh$t, how hard can it be for a fully kitted out workshop to change a timing belt?????

    Car went back to workshop and they pulled engine apart to show me timing was correct (Showed me the liquidpaper marks!) They suggest take my car to other Euro workshop (They all know each other) for second opinion, have also been this place before. Now car is almost undriveable, they ask did he use the proper "Timing tools"?

Said they could tell me stories all day! They reckon you are lucky to get 80K before major issues arise. Euro cars are filled with high tech stuff and it all goes wrong. Variable geometry turbos are to be avoided (They all have them, Min 4K!). If you blow turbo in BMW X5 will set you back 35K!! They suggest take my car to other Euro workshop (They all know each other) for second opinion, have also been this place before. Now car is almost undriveable, they ask did he use the proper "Timing tools"? They say "Should have come to them first!" engine will probably require head rebuild but they can loan me car for $45 per day.
    Hi leroybrown
    It's hard to know what to say ! Ring the NRMA and Consumer Affairs and get some advice about what remedy you can get. A dodgey repair is a dogey repair no matter what brand of car it is

    I would be getting a second/third opinion from a seperate trusted repair shop ASAP to determine the actual problem before it is terminal. A written report. Changing a diesel timing bet is not difficult but precision is necessary and usually some particular tools. Is there another shaft or gear which the "liquid paper" marks did not get right.

    The only engine which I heard made a noise on change of timing belt, was due to the incorrect tooth form belt fitted by an Dealer workshop to their own brand ute Your problem sounds to be worse than that.

    Get advice soon ! Jaahn

    For this, I would have it tilt trayed straight to Colliers. If that's too dear (the towing) I have a fellow who can do it for less on a car float.

    Car is now at another workshop awaiting inspection. I suspect valve and cam damage so likely looking at rebuild.

    If it is the same 2.2 as in the Citroen C5, 2005, then it will have a cam shaft at the top with 3 bolts that are adjustable, ie. with slots so that the cam sprocket can be moved to change the timing with the belt staying the same. Silly system I know.

    IF it is, then the timing can be 1-2 teeth out, even though the marks on the belt are all aligned. The timing is aligned by putting a pin through the crown wheel at the gearbox at TDC and then another pin in the cam sprocket (at about 3 O'clock).

    But maybe it isn't the same engine? Symptoms sound exactly the same as mine when I did it myself and got it wrong. Timing was way out and the fuel was being injected at the wrong spot.

    G'day Erik, I'm not sure if Renault employs that system as neither workshop mentioned it (My car is at different workshop now) also I have workshop manual that details how to strip engine and nothing is mentioned about adjustable cam timing. Think I have bent valves so will be rebuild, I am still awaiting report! Leroy.

    That is the safest bet, however, when mine sounded like a tractor or a tank, it turned out that it was the rocker arms that had broken, rather than the valves bending. However, it would be safer to take the head off and have a check.

    And this is why those of us who can do these things themselves do... White out marks used on a modern Renault engine...?

    I love that attitude were "we ****ed it up because we're lazy and don't care about not trashing your stuff" became "your car is crap and its all your fault for buying it".

    Hmm, sounds like they got the timing completely wrong or else something slipped soon after. I bet it is a bit hard to get another rocker arm from anywhere. It's going to be off the road for a while then, while everyone thinks about what best to do.

    Cheers, Erik
