Advice on engine noise

Dave_C

Hi All,

Firstly - Hi to everyone - just joined and this is my first post..

I have a Vecta SRI 2.2 Direct on a 56 plate.. Over the last few weeks I have been getting what i can only describe as 'vibration' coming out of the engine. Its intermittent - some days the car sounds just like it used to, other days it has the vibration (sound and feel)...

i can feel the vibration at idle, and it becomes really noticable at about 25000 revs , so much that if I look in the rear view mirror everything is blurred as the mirror is vibrating... That being said, some days the car is perfect - no issues with vibration at all.

I first thought that I had a hole in the exhaust, or had dropped a baffle - the sound is that noticable on a bad day. But have since had the exhaust replaced...

I have taken a pic of my engine, as I believe (from reading other posts) there are 2 engine types - sorry Im not a mechanic.

The last few days, i have also started getting a noise when I start the car from cold... after a few minutes the noiise stops, and doesnt tend to come back if I restart the car thoughout the day (from warm). It sounds like a loose chain sound to me, but again Im no machanic.

I will attach a sound file of the noise Im getting if I can figure out how...

Ive discussed with a vauxhall main dealer and they think it could be the secondary timing chain that has jumped.. does that sound plausable?

looking on line i can see reference to a Balance Shaft Chain, and a main Cam Chain.. I presume its the balance shaft chain they are referring to? would it make sense to have both replaced? and if so, any estimates on possible cost?

I dont want to go to a main dealer - does anyone know any good mechanics/garages in Bracknell/camberley area?

many thanks for your help..

Best thing to do is to get a video file posted as soon as, you would have to do that via youtube .there is a good chance that the timing chains need replaced you would usually get them both done together as a sensible move rather than just one or the other. the life of timing chains is 100 000 miles . Your car is nearly 8 years old so it could be time to get the chains done. It is also possible that the oil pump is faulty if it is this causes a terrible vibration noise as the camshafts are not receiving oil . you could check this by removing oil cap with engine running if the oil pump is functioning correctly you will see oil firing around the oil cap area .Something i have encountered recently , so it is another one to eliminate from your checklist .

Thanks.. I'll get a video done soon and post it - thanks for that.

The car has only done 42,000 miles, but as you say, its nearly 8 years old, so could be age as much as wear!

will post a video soon

My friend had a similar issue with his z22yh, it was indeed both chains needed replacing

where abouts in the country are you? I know Evocarlos does a brilliant job of both chains(he did mine not long back)and the price for the chains a gaskets are very good through the site shop or contact Matt(administrator) about the kits.
