    Hello. I drive a 1.2 Fiat Bravo with almost 60k on the clock. In the past few months I have heard a awful ticking noise coming from the engine while its running . Kinda like a clock but much faster. Its annoying because the engine dosnt sound healthy. Its not a deisel. Any Ideas?

    Heres my ideas.

    Loose timing belt.
    Blown head gasket.
    Value timing is out. Cam Shaft problem. Ever notice that Hondas and Toyotas are very quiet cars, cause they use Variable Value Timing. Very Good Teechnology. Anyway - Causes a knocking noise as if it was a deisel because fuel is combusing instead of being sparked off using the spark plugs.

    I have the same problem on my Astra. I kept being it back to Opel and they say its grand. I dont believe them and i am giving them one more chance at the next service interval.

    Is the car's power ok. Is the noise more noticeable when idle and goes away when you driving along. Check out www.howstuffworks.com and then go to the auto section very good and easy to follow.

    find out from fiat if they have hydraulic tappets or not, if it has, then you more likely haven't got enough engine oil, if not then they needs to be adjusted, I don't know the fiat engines but that would be noisey tappets, I'm not sure if I spell tappets right but the garage should know what you on about.

    This can mean that your engine hasn't enough oil. Check the oil level first thing because the engine could seize if there is not enough. After that any of the suggestions above are the next step.

    I have seen this happen in a Volvo and as soon as some oil was put in it was purring again...

    if its hydraulic they will self adjust so you dont get the ticking noise like a clock ticking very fast, but if they are not hydraulic then they have to be adjusted manually, not sure of any better way to explain it

    A valve lifter, or tappet, is simply a component that converts the rotary motion of the lobes of the camshaft to linear motion to actuate the valves. In earlier engines, this function was performed by a solid tappet, prior to the development of the hydraulic version
