I need to come back on this, puting 5w40 will create premature damage in time as was meant and designed on dexos2 5w30... The 5w(w-winter) is affecting cold ussage of engine up to 50celsius not the second number.

Sounds like chain to me... This engine is notorius for having on of the chain guids falling apart( good when catched early... Disaster catched when comlletly falls apart...)

Edit: if you are close to 100k do your chain wil save you a lot of "crying" later...
Sound is not coming from where the timing chain or the other belt sits. It is coming from the top of the turbo especially. I am going to try to weld the crack. Hope it works.

Update : Our mechanic found out that camshaft gear is causing tot his problem. And he said that we need to change chain and some other parts immediately. So the car is at the mechanics shop and gonna be done in 3 days.

After 10 months update : Our mechanic changed timing chain, tensioners and timing chain idler. He especially said that the sound was coming from timing chain idler. He also added that driving it like that would have made a catastrophic damage to the engine. Thanks. :)
 
The wife has an astra K with the B16DTH. I'm changing Oil every 8,000 in hope that chain / tensioner will last until we get rid at 140,000. ;)
I feel your pain. What age is it? I know there was a revision with 2018 on models inc my 2018 1.4t, to 0w 20 oil. When the chain & tensioner starts to go you'll know about it. My brother had an Astra J with the same engine, managed to cover 96k with it, without any timing chain issues, although his dpf packed up at that mileage. He was using it for short trips though, towards the end, which I'd advised him not to do.

It's on 18 plate mate. It's just out of warranty as it's 3 years old now and I did the oil change on it when we got it at 3,000, then 11,000. Dealership did it at 18,500 and I've done it again at 26,000 and finally at 34,000. Each change I've done I've used Shell Helix 5W-30 Ultra Professional AG C3. It does long runs all the time and she's well aware not to do short runs. Maybe I'll swing over to 0W-30 for future changes?
 
The recommendation from Vx for the 1.6D is Dexos 2 5w30 up to M/Y 18 and OV 0401547 0w20 M/Y 18 on,specifically if it's a B16DTH the recommendation is dexos 2 right through unless it's a euro 6d emissions spec car,
personally if i had one i would probably use the 0w20 myself regardless of year.
One thing to bear in mind if the chains/gears/guides are wearing and rattling is that they have now introduced a gasket
(part number55515025) to go behind the tensioner (previously no gasket at all)
this has a small hole presumably to limit the amount of oil drainback.

Vaux are doing them for free on a recall are they not? As long as your car has a fvsh & has covered less than 100k?
Although I don't think they'll change it unless your engine is rattling. At least the engine does not have to to dropped either to change it. Must be worth changing yourself though, prior to any rattling.
 
I don't think it's a recall George,it's their usual cop-out "upon customer complaint"
but it may mean engine out if any damage is found
"2. Inspect the timing chain tensioner and the timing chain for damages
Note: Replace worn and damaged parts"

I thought vauxhall were replacing this gasket for free if the engine was rattling and the car had under 100k on the clock? With a fvsh up to the age of a 10 year old car. There won't be many cars that fall within that criteria mind.

Not seen any confirmation of miles/years parameter
but that definition of replacement is "upon customer complaint"
a recall is whole lot more expensive for them ;)
 
so how does customer complaint work? do I need to have had a full vauxhall service history, which I don't and does the chain need to be rattling or can I just mention about the gasket and get it fitted? even better, how is acess and I'd purchase the gasket and fit it myself if I can get into it easy enough? cheers
 
Hello , I understand for chain tensioner gasket part number , but do you know for new revision of chain tensioner part number and I hear for new cam cover gasket if some know part number.
