LOUD ticking noise

t111mts · 30-01-12, 02:11 PM

Hello,

I have just purchased my MK2 ZS 180.

All seems OKish

I dont know if I am just being paranoid because I have been reading loads on the forums, or if all is ok.

I have a very LOUD ticking noise coming from the car.

You can hear it with the lid down and is clear when idle or driving.

Now, I have read about VIS motors and the inlet manifold being common problems.

Car feels smooth enough but not getting much power in low gears / revs

Any other suggestions and does anyone have any PICTURES of the VIS motor or how to remove/replace so when I open the bonnet I can see what I am sposed to be looking for??

Thanks in advance

Could be purge valve, lift the bonnet and see where it is coming from, or could be a valve if low on oil.

VIZ sounds like a bag of spanners.

The purge valve is to the right of the inlet manifold, the Viz directly behind the engine.

Does the noise alter with engine speed?

A search of the forum should bring up photos.

I'm thinking maybe not the purge valve if you can hear it with the bonnet down. Does the noise keep time with the engine if you rev it?

If it is a dodgy plenum, it's relatively cheap to stick a second hand one in.

Thanks for replys

It sounds like it is coming from very low down in the engine. Almost where the aitr filter is?

Its a constant ticking.

Quieter when cold engine, louder after its been running for a while

I have made a very crude picture to try and help me to explain!

Loose coil pack maybe, or even a loose sparkplug, blowing exhaust manifold.

I will check for this thanks.

You see those 3 black plugs right where the arrows are?

What are they??

Coil packs, from memory they each have a 8mm bolt holding them on.

Defo sounds too low for plenum.

I see, this will be the first thing for me to check then.

One of them looks extremely clean compared to the other 2, so one may possibly have been changed.

Does this mean 3 coil packs or just 3 plugs going into 1/2 packs??
