Astra Coupe rattling/ticking

villadam

Hi my astra 2.2 is rattling/ticking, i cant pinpoint exactly where the noise is coming from in the engine bay but it isnt quite there when i start the car from cold but once its warmed to temp its quite loud and changes speed when i rev it. Is this the cam chain also just noticed ive got a slight oil leak. any help much appreciated cheers

Do you know what grade of oil you are running? When was the last time it had a service?

I serviced it a couple week ago put 5w30

I did a video this morning as I got to work engine was running at temperature.

5/30 is too thin for these engines. You should really be running 10/40

The vauxhall service manager told me to use 5w30

They are incorrect. 5/30 is only recommended on >2005 engines in the VX range, so the Z22YH would be OK running it, but the Z22SE needs the thicker 10/40 semi synthetic.

Have you seen the video I uploaded do you think it would make a difference the thicker oil

I've not got my headphones at work, so I can't listen to it. I'd recommend swapping the 5/30 for the 10/40 oil though.

It's only £11.50 for 5 litre of oil from Autovaux : http://www.autovaux.co.uk/LoadPortal.aspx?cnum=72&pnum=AS93165216&tabid=5&vnum=128

Yea don't play it out loud sounds like a diesel truck lol

evocarlos

i think mine will sound like that soon lol
matts right 5/30 make these engines noisy but the noise on your engine is a bit more severe
maybe stuck lifters

villadam

it doesnt rattle when cold but soon as it warms up its like the video but car drives fine with plenty power as before

Sorry but I put 5/30 from Vauxhall in my 2003 astra coupe when I did the head and chains and it is as quite as a mouse. No rattles, apart from the loose heat shield underneath.

then you were lucky
put 5/30 morris oil in mine after the rebuild its was a tank it was only in there a day then 10/40 gm went in
herd a few now running 5/30 and i consider them to be loud 🙂

I'd suggest that your engine is wearing rather than you used the wrong oil.

evocarlos

lol the oil wars 🙂
im gonna stick with 10/40 been good enuff for the last 57k miles and it dont burn any yet 🙂

I put 5w30 in and It is noisier when the engines cold. Will be changing to 10w40 next time.

villadam

Been to see a friend today and he thinks 1 of the lifters are stuck is this an easy fix and how do I go about it

jwalker

Timing chain off, camshaft out then just swap over

evocarlos

as above
hope this link works 🙂

This sounds very much like the chain and tensioners. This happened on my 2.2 SRI Direct. Its likely to be the guides worn and probably cracked, get this looked at now, Daz sorted mine out.
