- Hi there. My car is an Astra 1.6 Diesel. I noticed a weird sound today. I have added the video links down there. Can anyone help me about what are the things that can cause this sound? Thank you.
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.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...
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.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.![]()
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?I feel your pain. What age is it?

Good idea, I'd do the same too with that engine@Valer Sweet Info mate, appreciate it. I'm going with your rec of 0w20 and if we ever have to get chain / tensioner replaced then we'll get gasket fitted. thank you..
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?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.

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.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"
Not seen any confirmation of miles/years parameterI 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.
Found it, was a tec bulletinNot 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![]()
