anyone tell me what it could be? can also hear it when driving

VZ V6, i'm guessing that the timing chain might be starting to stretch. I hope for your sake that thats not the case.

But you should take it to a mechanic to get it checked out, could be something simple.

ahh how much is timing chain?
Approx

I'm not sure exactly of the cost sorry. But I know someone else who had the same problem. He had to get the timing chain, tensioners, etc. Problem was that his timing chain stretched too much and jumped a tooth or two and it would run after that.

A few members of this forum have had to get their timing chains replaced on the Alloytecs, hopefully they will be able to give you an idea.

No problem.

To switch the fog lights on, turn the parkers on, then pull the switch (headlight switch) towards you, if that makes sence.

^ As above, pull the headlight knob towards you or "out"

I have a very similiar problem!

• In the mornings, when i start my car, it always roars then makes this loud cracklin sound. This stops after 3 seconds.
• But if ive been driving the car around then turn off the engine and turn it back on again it doesnt crackle.
• If i drive to work then park my car for the day which gives it 8hours to rest then start the car for the cruise home it crackles?
Seems to me whenever the engine is cooled down it crackles when starting up.
Also my car doesnt crackle when driving.

Whyyyyyy is this???

lack of lubrication around the timing chain, normal and nothing to worry about. mine has been doing it for 80,000km

Is there plenty of engine oil in it? Could be running low or more likely its the wrong grade. 10W-30 required I think.

check your dipstick mate.. the timing chain is covered by the timing chains are covered by the timing chain cover. Which is fed oil from oil valleys, so if your engine has oil, so does your timing chain

i asked for a quote to get my timing chain changed it was over 3 grand the mechanic told me, because you need to by the rails and everything they run on because its all made of plastic. So if its stretched you need to replace everything along with it. my car has engine knocking in cylinders 2,3,4 and 5 unsure how to fix the problem not even a mechanic can tell me they all said they will need to pull it apart first before they can give me an idea on how to fix it. Anyone know if this is true or can it be fixed another way?

[richardpalinkas]

What I meant by lack of lubrication is that the oil drains back to the sump, so once all the oil drains back, the chain is not as lubricated as in normal driving, as the oil has not circulated through the engine fully on first startup. Only get worried if it starts being very rattly for majority of driving

haven mine checked monday, hopefully nothing bad

[vs v6]

took it today cause i had some time
and the mechanic said it might be the cyclinders? is that possible? with some knocking noises
