Help Please Anchorman!

[lloydp]

I've only just got round to trying to sort out the problem from this post as my MOT is coming up: http://www.toyotaownersclub.com/forums/index.php?showtopic=117473&st=0

The car is showing fault code 34, which according to my crappy Haynes manual is 'turbo sticking closed'. I suspect the component marked (2) in the photo as that was the part I squirted oil into last time. I thought that was the VSV, but looking at your pdf of the VSV test, that looks more like item (1) in the pic. (1) has a pipe entering from the front of the engine, and a pipe going to the turbo pressure valve above it. Item 2 has a pipe going to the turbo itself, and one to the (vac pump?) below it.

So my question is please, which is which and if (2) isn't the VSV what is it and can it be tested?

David - ancs is shoveling heavy snow off the M25 area just now but should be back in soon.

Thanks mate! Don't envy that job...

Its the one with 2 pipes on - one to the turbo. Can't get at my pdf at the mo' to check what it says.

Was trailing around Stockport shops actually!!!

In the vsv.pdf you've published before, the part looks exactly like no. 1 on my pic. I'd re-upload it but the forum doesn't seem to want to play ball with attachments! David

There's this one for the VSV;

.....and this one referred too as the VRV which is used on early models to control the EGR (later ones are electric);

egr.pdf

They are similar looking control valves.

Thanks Anchorman. Now I'm really confused!  In the vsv.pdf my component (1 on my photo) is identical to the one shown. Its function is seemingly to just switch the turbo pressure switch above it, and is attached to it by a short tube underneath. The 'inlet' pipe is not connected near the egr though - it goes to the front (ie front near the rad) of the block where it is attached to a small nylon filter or suchlike on the block.  The other component (2 on my photo) has an electrical connection but otherwise looks 'similar' to the e-vsv on your diag. The 2 pipes are connected to a) the 'pump' thing below it (the thing with the violet label), NOT the EGR as the EGR is the electric type, and b) the turbo via a nylon filter or suchlike.  Part (2) is the one that I squirted some oil in to the end after my older posting. As this was the only thing I touched before the car went wrong again, that's why I suspect it rather than the MAF sensor as being the cause of my problem.  Any ideas please?  David

I haven't got a lot of time today but if I get chance I will call around my mates and study his to see how it compares. In the meantime does it look as if you could pipe yours up as shown in case somebody has got it all wrong in the past?

EDIT; This is the later arrangement;

[lloydp]

Yep, that's the same as mine, but what do you mean by 'pipe yours up as shown' please? (ie shown where)

Edit: Just in case I've been really stupid and got the pipes reversed on component (2), would there likely be any damage to the turbo if I reversed them and drove it?

[anchorman]

I mean pipe it up as shown for the VSV if not already that way. Running it the wrong way won't harm the turbo but it might not run just as it should.

[lloydp]

Did you manage to get round to your mate's (guess not)? Was worried if I ran it the wrong way the turbo would be running at low revs!

[anchorman]

No - afraid not. Won't get chance before next weekend now I'm afraid. Is there one you can look at locally?

[lloydp]

Unfortunately not. Guess my best bet will be to go to a Toyota dealer and say hey what's this component! (and how much...)

[lloydp]

Just a quick update. Kingo tells me that part is the vacuum regulator, £285, and kindly supplied me with this diagram

[anchorman]

I think I would try a scrapper first then a new one if it shows promise.

[lloydp]

Well, I'm almost too ashamed to post this. The pipes on the vac control valve were reversed, not surprising the turbo was complaining. Now have a 'real' car again...

Never mind - at least you got there
