Oil catch can time.

Glad to hear it running, and better than before, and also glad my ramblings of some assistance too!

Very nice to share mechanical tips and experiences its always good to know someone is there to give some advice . ( ive got my eye on a 307cc).

FOUND OUT WHERE THE WHOOSH NOISE COMES FROM

So driving today about 2 miles to go till home , WHOOSH .. and i mean a big WHOOSH !
Pulled over popped the bonnet this pipe in the photo was almost out of the turbo the bolt housing plastic had all broken and the bolt was lose the bonnet copped some nice fine mist of oil stuff so i drove back home 25mph for the last 2 miles refitted washers bolt and new nut plus 2 cable ties for extra support , went for a run all good again, so I'm needing this pipe which I've seen for £55 new on ebay .

[MattBLancs]

Do you mean this bit?

It's like that as standard.


Should be a wierd bolt: integrated washer, shallow 10mm hex head, on the turbo that secures it. You back it off a couple of turns (remove the one opposite - off the top of that image - completely) hose clip off, pop rubber mount (sat on ball on heat shield bolt) then have to rotate this piece around the axis of the turbo outlet to decouple from this weird bolt

[Huskyxantia]

No the other side , this photo was taken the other week when it was off the car, its the one that the bolt goes through.

& heres the one i meant to post up

[MattBLancs]

Ah yep, that's definitely broken!

How odd for that to give up all of a sudden.

[Huskyxantia]

It was cracked when i first got the car last year i guess it was just a matter of time, I've a question regarding the wastegate adjustment on the turbo how or when would you know if it needed adjustment at all ?

[MattBLancs]

No wastegate on these, a VNT turbo. Actually, an assumption that you've got the 110bhp version - thinking about it, I know you do as seen your VNT internals on earlier post.

Note: 90bhp version is different turbo, conventional, does have wastegate.

The VNT actuator does need setting up when turbo has been apart. I tried to set mine same as before (i.e. movement seen when plugged in to a vacuum pump. Set it at the same gauge reading) but it's fair to say failed to do so.

Mine (well, my wife's) is poorly adjusted - symptom is doesn't drive as nicely as it used to, off boost..... Nothing.... Then sudden loads of boost. Goes like stink. Suspect is over boosting but hasn't thrown codes to that effect. I intend to fix it, but haven't been able to find info as to how to set it up. Did find one company offering set up of VNT actuator, but not investigated further.

This is going to be an on going investigation .

[Huskyxantia]

Found this .

[Huskyxantia]

This is good. Different car same principle

[MattBLancs]

This is good. Different car same principle

Just bear in mind that's conventional integral wastegate type turbo (not VNT like ours)

Will have a watch of the other video now,

Matt

[MattBLancs]

That first one is "normal" turbo too.

Try this one, about 3:48 he describes adjustment of VNT actuator:



My cheap eBay vacuum pump, generally similar to the "mightivac" used here, is poor in terms of both accuracy or repeatablity. Have used it for vacuum bleeding a few times since (and is brilliant for that) and the needle on its gauge doesn't even return to zero when vacuum removed - so get a feel for the inherent quality!

I did check mine earlier it sits about right , closed flap position is adjusted just a little over on the adjuster nuts and ive got it not to tight but not to lose either.
