    Hello,

    I wanna pop down to the local mechanic to get him to change my spark plugs changed. I have bought the spark plugs already so no need to pay for them.

    Just want to know how long it takes for a mechanic to change a set of plugs so i don't get ripped off?

    Thanks,

    Gil.

    honestly, it is the second simplest spanner job you can do to a car. Do it yourself :)

    It took me about 15-20 minutes to do mine. And Im just a ham fisted amateur.

    It's easy enough to do yourself, but an indy mechanic shouldn't charge you a lot really, It's normally a 15minute job but a mechanic will probably want 30mins labour unless you can just tempt him with beer money.

    15 mins. even if they bother to use a torque wrench and do it properly, which they wont

    I never bother with a torque wrench for the plugs either.

    I'm thinking about doing the plugs myself in the near future. What is the correct way to tighten them without a torque wrench? Hand tight, then a quarter/half turn?

    most cars are alu topped these days, do it by hand till its tight. never had any problems other than clearing out threads on dirty heads.

    Took me about 5-10 mins to do mine on my Focus. You do need a socket set with an extension bar and a sparkplug socket. So probably cheaper to get a mechanic to quickly do it unless you can borrow one.

    I was a bit scared that the plugs would be stuck or that i would cross thread but it all went fine and cost me nothing. Just make sure to hand tighten first so that you can feel its not cross threading.

    Also, get some copper grease and apply it around the thread of the new plugs. You'll thank your lucky stars you did next time you replace them :)

    Depends on the car, mine or my father's would be about 20 to 30 minutes, as you need to remove the engine cover, and the coil assembly, and there's 8 of them. My brother's or the family abuse machine, 5 to 10 minutes. So what's the car?

    It all depends if it has an Intake Manifold going right over a bank of Cylinders that you have to take off before you can get to them, like mine :p

    Good designing Toyota :p

    No, Alfa used to do a 1.7 (and 1.5) boxer engine. Was fitted to the Sud, 33, Arna and some early 145/6s.

    I changed some on a MX5 once. Turned into a nightmare - one had seized in - no copperslip applied on fitting! :(
