General Car Chat / Re: Zafira B 1.6 top end noise.
« on: 05 March 2024, 12:48:30 »
Had half an hour this morning so whizzed the top timing cover off. I am more sure now than I was that it's a cam dephaser but keen to get views on the video below.

The exhaust cam bolt isn't running true, you can see a wobble at the bolt head in the video and when I placed the tip of my knife against it you could hear it was only touching on part of its rotation. The inlet cam appears to be running true based on the above two tests. Interestingly, the noise is noticably worse when the engine is warm vs cold. Not sure why that would be (any ideas?)
Any ideas on anything else that could cause what's seen/heard on the video? I'm not thinking it's lifters, mainly because taking the oil filler cap off and listening there doesn't make the noise change.
PS. For completeness I checked the oil level (fine) and read the codes - only one present p0597-61 thermostat valve stuck. I fancied this was the case as the heater is slower than it should be to warm up. But I can't see any connection to the issue at hand

« on: 04 March 2024, 23:35:57 »Have you cleaned/removed the screens from the VVT solenoids
There was a TIS thingy about them clogging as they're too fine.
I did. When I first got the car (nearly 4yrs ago) it made an oil starvation type noise for a few seconds on startup. One of the things I did chasing that issue was to remove the VVT solenoid screens (they were pretty clean anyway but I thought why not).
Turned out that noise was due to a damaged oil drain valve in the filter housing allowing the oil to drain back to the sump when the car was sat a while. New valve cured this.

« on: 04 March 2024, 21:31:34 »Plenty of oil in it?👣👣👣
About 7/8 up to the full mark (first thing I checked when the diesel clatter started
what engine code ? Z16XEP and XE1 don't have sprung lifters that fill with oil ,they are more of a cup/shim
Common issue is the baffles in the intake manifold become un-glued ,this results in a NOCK sound (can sound terminal )
I've done this job ,wasn't convinced that the baffle being loose would make such a racket
so I ordered the shimmed lifters (set of 8 exhaust)
spent a few hours cleaning, re-sealing the intake
it was cured
£100 worth of lifter shims came , and are having a "rest" in the parts hoard
Z16XER, hence my suspicion of the VVT inside the cam sprocket. I will start with the top timing cover and go from there, given the outrageous racket, I'd imagine there will be play somewhere even with the belt in place. Also, if it is that, removing the cover could make a noticeable difference to the noise.
That said, I will be sure to get my finger in the hole as you suggested, give it a waggle and see if anything's loose.
I hadn't heard of the inlet manifold baffles before, so that's good news information, thanks

General Car Chat / Zafira B 1.6 top end noise.
« on: 04 March 2024, 18:36:00 »
I am doing my level best to try and get rid of the zafira, but the damn thing just won't be gotten rid of. It's latest ploy is a top end noise. The car is also as flat as a witches tit.
It started about two weeks ago, approximately one week and 250 miles after I did the timing belt, water pump and tensioners. It has started out life as a diesely thrum but has graduated rapidly to a nasty sounding rattle that definitely signals a significant issue.
When it was a thrum I was thinking hydraulic lifters, by with the nasty rattle I'm thinking it's one or both of the cam dephasers disintegrating. My theory is that the new tensioner and belt has better tension than the 14yr old 103k ones that came off and it's put more stress on the cams.
To answer the obvious, I checked the timing twice, then checked it again, but my first port of call is a strip down to look it over one more time.
Sny advice greatly appreciated as always!

That sounds Omegaesque to me......does the same apply to the Signum?
Don't know for sure. But it does to the Saab 9-3 with the same engine. Thread below talks about adding an aftermarket item instead of the oil/water standard one.

I think some vectra c/signum had the transmission oil cooler running through the main radiator. Maybe worth checking for oil in the coolant and vice versa.
Should be obvious when the transmission oil is changed.

You don't half have some bad luck with that pussy of yours. I've had 2 punctures in the last year and I feel fairly hard done to!

« on: 29 February 2024, 00:07:57 »Getting closer, picked up our US Dollars today ✈️🛳️✈️🛳️
Mick, little tip for you which may come in handy should you run out and need more USD. The ships all have cash machines on but charge a hefty fee as you might imagine.
However, if you go to the casino onboard you can load your cruise card with any amount of cash from your bank account/credit card to bet with no fee. You can then immediately go to the teller and cash out in whatever the ship's home currency is (all USD in the Carribbean), again at no charge. No need to bet anything.
I've used this trick once or twice as we tend not to take much physical cash with us when we travel.

Thanks for the heads-up TB, although I am a little disturbed that this means I may have to talk to my family

When you get it done, it may be worth requesting the old compressor back and rebuilding it. It's normally the little piston rings (plastic) which wear and cause sub par performance.
The rebuild kits are very cheap and you have a spare in case it decides to give up at an inconvenient moment (just pulling off a caravan site springs to mind). Swapping them over is a quick and easy job.
My parents ran P38 range rivers for over a decade and my dad always kept a rebuilt spare as a just in case. Came in handy a couple of times as their place was miles from civilization.

This is exactly right. It's all very well saying you should run an older XYorZ but when any kind of minor repair at a garage, or even routine items like suspension bushes runs well into three figures it makes much less sense to buy cheaper older cars.
For a lot of people a £500 bill (easily achieved these days) will quickly become £6-700 by the time the credit card company has had its due.

But yeah.....£200 PCM for such performance makes it very tempting. Presumably this low figure is linked to a 'high initial payment' on PCP, or similar.
Salary sacrifice lease again, so saving around 60% on a regular lease, also no VAT
.I was tempted, but it had to be appliance white which just doesn't interest me. The Smart Barbus #1 is around £275 and offers similar performance in a proper colour 🤔
