Another attempt at fixing the gearbox drip

Filed under: Saab — Administrator @ 3:28 pm

It looks like WMSS efforts fixing the a leak from the reversing light switch didn’t work.

Oil was still escaping from my gearbox, albeit very slowly.

Not fancying a trip to Birmingham as I am very busy at the moment, I decided to go to a new local garage who have been doing work on my gf’s car. They operate out of an unnatractive estates with many derelict units, but the guy who runs it seems very good and has a good reputation.

Once the car was elevated I had a clearer view of the gearbox, as shown in these photos.

From what he could tell the leak seemed to be coming from the bolt at the bottom. There was no evidence of an oil trail above it.

The bolt was removed and refitted with some gasket sealing compound.

Hopefully this will do the trick. My drip-tray is back under the car so I will wait and see.

While I was there I took some more photos – my new turbo pipes

and the shiny end piece of my exhaust.

Another service complete

Filed under: Saab — Administrator @ 10:35 am

Yesterday the car was back at WMSS for more work.

Had the usual oil and filter change. Mobil 1 5W40 went in although the garage would use 0W30 fully synth if left to their own devices. I am doing some more research to find out which is the most suitable oil for my use, and a question has been posted to the knowledgable oilman on the XPower forums.

My rear brake pads were removed, cleaned and refitted. The squeak is still present though. Not sure what to do now.

The turbo coolant and oil feed pipes were replaced. These looked ok from the top but the underside was rusty and flaking.

The charging system was checked and all seems to be ok. I guess the failed battery was just faulty.

A new pollen filter cost £39 + vat :(

The oil drip from the bottom of the gearbox was tracked down to the “reverse selector switch”. Apparently this was fitted without a seal, which seems rather strange as if it had been replaced, new switches come with the seal. A different type of seal has been fitted and hopefully the problem will be sorted.

Images of the oil which escaped, and the drip location are below.

Oil drip analysis

The mechanic thought there was a whining noise from the left side of the engine which could be one of two idler pullys or the power steering pump. Unlikely to be the alternator as that is only 15 months old… I can’t hear the whine, and as I had just coughed up £320 for work, am happy to leave it until it gets a bit louder.

The car is now nearly “perfect” other than my squeaky brake and the whine I can’t hear.

Everything is working well and in good condition.

What will go wrong next?

3rd Battery

Filed under: Saab — Administrator @ 1:50 pm

I have another battery

I tried charging the 0.0V battery.

Charging it on a constant voltage power supply thr current drain increased with time. Charging it on a car charger the voltage fell as the current rose…

I managed a couple of times to get it up to 11 volts, but both times it fell over a couple of days to 9.5 volts when not connected.

I put my old “acid spray” battery in the car. This has been in for 9 days and working fine. I even left it for a week and it started with no problems.

Tests with my multimeter indicate a drain of about 35mA which seems acceptable.

I returned the damaged battery today and intend to fit the replacement this evening.

The car is booked in with WMSS for a service soon. A whole 3 months between oil changes! I am also getting the slow oil drip looked at (think it’s still there), new pipes on the underside of the turbo, my squeaky rear brake sorted, and the charging system checked.

Maybe someday everything will be perfect all at once!

Lovely new oil

Filed under: Saab — Administrator @ 6:55 am

Received my lovely Mobil 1 yesterday :

6 litres for 33 Euros works out at £22.50

If a 4 litres is £39 in the UK, and 1 litre bottles are £12.99 as they were at the weekend in Halfords, buying the same volume would costs £65 (or £58.5 if you bought multiple 4 litre bottles. Why 4 litre bottles? They sell it in 5 litres in France and who has a car with a 4 litre oil capacity?

So the French version is either 1/2.6 to 1/2.9 the price of the same thing in the UK.

Just a shame my car is still on the driveway with no electrical power. I have decided to reconnect the fully-charged old battery in series with my multimeter to measure amps, and take a look at what is going on. Hopefully with some fuse-pulling I will be able to find the problem.
