Chain tensioner rattle again
« on: 30 January 2019, 08:42:29 PM »
Well I've been using Jet for work this week. Today it was very cold when I got to the car park so ran the engine whilst I scraped the ice off the screen.

I could definitely hear what I can only describe as a slight regular gonging (Notting Hill Carnival steel drum) noise coming from the engine that I suspect is chain/ tensioner rattle. It was more noticeable than I remember, though not a total disaster.

When I got home and the engine was hot, I got out of the car to listen and the noise was gone.

So now I want to get it investigated and sorted, so interested in any Saab specialist recommendations in the Warwickshire/midlands area. I have used Hallam & Sutherns before but they are 50 miles away from me. Similarly WMSS, albeit a bit less far. Someone has suggested a place called Ashby Garage, but I don't know them.

Can anyone recommend a specialist I could try?

My grandson had a service and MOT done on his 9-3 (our old 1.8t) at Lime Garages.  This was the name of the old Saab dealer in Leamington.  When that closed, the mechanics moved to the other garage in that company which is the Kia dealer in Stratford Rd, Warwick.  When I last went past, there was a "Lime Garage" sign over the door around the side.

Grandson is a non-mechanic sort of guy but felt he had been treated OK, unlike the Nissan garage he used before.  They did the service, rang him for authorisation on fixing one issue for the MOT and he was talked through a list of "advisories" that needed addressing soon (not MOT  ones).  These were also listed on the invoice.

Maybe worth asking them for an opinion?  I know one guy who felt that they were not knowledgeable about things, but he's a chartered engineer, like me, and we have a different view of the competence of garages!!

I rang up the Lime Garages at the Kia Garage in Warwick. I believe the dealership is owned by the same people who used to run the Saab dealer franchise in Leamington.

They were fairly expensive when I was ringing round a handful of specialists last year, so I didn't use them. Location wise they would be ideal.

I'm leaning towards WMSS though (or H&S) as I can get a courtesy car off them whilst mine is in. In the case of WMSS, I might even find myself in a 9-5 again  for the first time in 13 years!!!! :D

Just had a quick chat with a guy from Bagnall Saab in Birmingham about my Aero with the potential chain tensioner issue.

Can anyone recommend these guys? They're a bit of a distance from me, but if they are good, and can give me a courtesy car, I'd consider taking the boy over to them to have a look at.

I rang Ken M Jones in Rugby but there was no answer. I have previously used Hallam & Sutherns, but they are a 100 mile round trip from me. I would go back to them again, but had seen people speak highly of Bagnall, so thought I'd call them. Bagnall should be a bit closer than H&S.

I've not used Bagnall, but I have heard that while they know their stuff, they tend to over book and jobs can take a lot longer than you expect.

If I can get a courtesy car, that doesn't bother me too much. The boy spends most of his time on driveway duty, guarding the house at the moment!!!

Except for when I use him for work for a handful of days, or take him for a blast because I can ;)

WMSS messaged me to suggest a balance chain/timing issue too which was what Bagnall suggested it might be too.

Just want to get it sorted now so that we can start using him a bit more (and then I can move onto the bodywork ;) )

Finally going to get this investigated at WMSS next week. Hopefully the boy will be back smooth and svelte ;) .....and fast!!!

Well, I've bitten the bullet and dropped the boy off to WMSS this afternoon. Will see what they find, but I'm bracing myself for a biggish bill for the chains alone. Not a problem, because I've been saving up to get it done anyway, and I'll feel a whole lot better driving him after they've been done.

Parked up next to a 57 reg black 9-3 that looked a bit like mine, other than it wasn't an Aero (it was a Vector). I was looking forward to perhaps getting a 9-5 as a courtesy car, as I hadn't been in one since that fateful day I traded mine in all those years ago, But no, he said it was a 9-3 diesel auto, if I was OK with that, which of course I was!!

There was a nice red 9-3 in the car park, and I asked if it was that one, but no.....it was the black one next to mine ha ha.

So now the neighbours won't even notice that I've got a different car for a day or two :o :D

Day two, and they're still working on it. No news of any "issues" though, so fingers crossed all is OK.

This diesel auto goes well, but feels very agricultural when started up and driven at low speeds. Makes me realise that despite the idle vibration in mine due to the potential chain/tensioner issue, it is still a nicer place to be.

That said, on the motorway and giving this diesel some welly, it does shift ;) And that is before any remap I assume ;)

Well, got the call today. WMSS have finished the work on the boy. Won't know what else they have done, but it sounds like at least both balance and timing chains and tensioners have all been replaced, and they've done an oild and filter change (so that's my service for this year ;) ).

I'm hoping they've changed the transmission fluid, two bottles of which from the VX dealer I left in the car.

I asked them to look at the intermittent external temp sensor issue too, which may be a wiring thing. I'll pick the boy up tomorrow afternoon and hand this 1.9TiD Auto back, that I have grown to like quite a lot whilst I've had it. But, can't wait to feel how smooth and quiet my car is again.


Next stop might be remap....or should I get those rear arches sorted out first? ;)

Do the remap. You will drive the car faster, which will increase airflow and dry the bodywork, which in turn will slow the rusting... ;)

Well I collected the boy this afternoon. Initial impressions were good.

I used to get a sort of drone noise around 2000 - 2500rpm on acceleration. That appears to be gone.

The intermittent idle vibration seemed much better. However, in traffic later, it seemed to be there, although when it was there it didn't come and go irritatingly like it did before. Seemed more consistent.

WMSS have done the timing and balance chains, and replaced the external temperature sensor, which was playing up a couple of weeks back. Not cheap all in - was around 780, including oil and filter. They also changed my transmission fluid with the bottles of gearbox oil I left in the car.

So will see how we go. I hoped the idle vibration would be gone completely. As it hasn't, would this suggest a possible issue with the exhaust, engine mounts?

What is the idle vibration (especially in traffic jams etc) like on other people's B207 engined cars?

The varying idle speed is still there, but not as erratic as before. Will keep any eye on it though, as now that the chains are done, I feel better about using the car a bit more than I was before ;)
