Locking tool is highly recommended:

Actually now I come to think about it, it could be a chain setup.....memory must be failing me!

Being on here too much. I think its catching.

Just hope i dont catch some of the other ailments they chat about on here!

Okay, Corsa bought yesterday so now i've a few more questions about them 
I would describe the car as "honest" with no attempt to hide anything so i'm pretty happy providing nothing goes bang while it gets some very very well deserved TLC 

Oil question ............ The oil is frigging disgusting    She can't remember the last time it was changed and to say it was black is the understatement of the year     I dumped the oil immediately when I got back and treat it to a sump full of fresh 10/40 which turned jet black within 10 miles    The front of the sump is starting to corrode and I had to use a strong arm to get the sump plug off so i'm looking at removing the sump and scraping out any crap then wire brushing it before blathering it in hammerite paint 
Is it recommended to use engine flush on the 1.3 cdti engines to speed along the cleaning ?


TIA 

Temp question ............. The water is clean with evidence of a radiator fitted very recently but in the 110 miles i've done in it, the temp has never risen above 80 deg    The air through the vents is nice and hot so the heater matrix seems okay.  What is the normal operating temperature for these engines ?
Where is the stat on these and how much for a replacement ?

If the oil is as bad as you report, then a flushing oil is a very bad idea!

Treat it to 3 or 4 quick oil changes, ensuring that you do the filter each time. Use the cheapest appropriate oil, as it will only be in there about 200 miles.

I'm with Nick on this,flush can cause other issues.

Slight hi jack as there seem to be ones in the know..

Poor starting hot or cold, fuel rail pressure seems to take a few turns before the pressure builds to a point of starting.

Tinternet seems to imply that fitting a new higher output starter motor is the/a cure rather then mess with hp pumps and regulators. (no fault codes)

?

Coolant temp suggests a lazy stat easily tested by holding the hose from stat to rad and starting from cold

Engine oil does go black more or less as soon as you start it up after a change on diesels (well on mine anyway). I do mine on the Skoda every 4000 miles and as soon as I've changed it & took it for a little run, then brought it back to check the level its as black as the ace of spades.

So the summary is .................... the oil will get filthy very quick so give it a few quick oil changes and give it a good flush and new antifreeze after a stat change 

Thanks for that lot lads 

Engine oil question ............... its running on 10/40 GM stuff at the moment but the hand book says you can also use 5/40 or 5/30 

What's the best stuff bering in mind that its done 96K and I don't think its had many changes.
The engine pulls VERY WELL from 55 upto 85 in 5th (private road mr plod  ) and is pretty quite once its warmed though but it does rattle its tits off when cool with what may be from the bottom end 

Gearbox question ............. Its the 5 speed box and probably has 11 years old oil in it.
Is it worth dumping the gear oil and refilling ?
If so, what with ?

TIA

It's a diesel, so the oil will turn black very quickly even when everything is OK.


You don't use flushing oil when it hasn't had proper changes as all you (might) do is loosen the rubbish that changes avoid. Having extra dirt and sludgy oil circulating is not good for the engine or turbo. You don't use it when it has had proper changes because it is unnecessary. Flushing it with just oil is far gentler than using detergents.


If the gearbox has drain and fill plugs then an oil change certainly won't hurt.

I'll have a look when I get chance Nick, thanks 

Any idea what oil goes in these gearboxes ?

[Marks DTM Calib]

80 degrees is bob on for a CDTi.

A few short period oil changes is advisable.

They are supposed to run on fully synth but semi plus a more regular change approach will be ok.

It will be noisy when cold anyway, nothing to much to worry about here, a splash of 2 stroke oil in the diesel helps but, the CDTi only fires the injectors a few times every cycle rather than the big numbers on other power plants (this is how they make them quieter). The result is more noise but, much much longer lasting  and more reliable injectors.

As for cranking, they can take a turn or two, no issue here, measure the glow plug resistance (they are fed in pairs so a single failure wont show up as a fault). Not many issues really on these to be honest.

For gearbox oil, its always worthwhile changing at elevated mileage, find a good fully synth oil (I don't rate the Gm gearbox oil)

F17 gearbox if its a five speed so probably 75-90 or 80-90

Cheers for that info Mark
I'll get some oil later when I get the antifreeze
