Help!!! advice needed, error 34 and no ooomph!!!

Does the inside of the downpipe look like the wastegate arm has been hitting it? Yeah you can still test the actuator the way you have it now.

If you want good quality gaskets just use either genuine toyota or check tcb parts.

I would say a garage would charge you about an hours labour to do a cp but i could be wrong. Only saying as thats roughly how long it takes me maybe not even an hour... but i check plug gaps and condition while theyre out.

Getting that Down pipe off was a real PIG!!! had to take oil filter off to get at one Nut.

This wet towel jobby to check for leaks, do we think we can do this at exit of turbo whilst i have down pipe off to check exhaust manifold isnt leaking?
and by that do we think I could do it safely? would only need to have engine running for a few secs of course.

Just noticed you've already removed the downpipe, no don't stick a towel in the turbo. Can you see any black sooty deposits around the manifold gasket? The leaking turbo/downpipe gasket could be messing with the O2 reading, causing it to run rich.

As Kev says now you have the downpipe off take a look at the inside of it to see is the wastegate has been hitting it. Also it's a good idea to move the actuator arm to fully open and put a paint mark on it or similar, so that then when you repeat the test with the de-cat on you can see if the arm is able to extend to the same position.

In the picture of your cam marks the exhaust one looks like it's a tooth out, but it's not always easy to tell from pictures. If yours is a Rev1 then you can take the cam cover off and check the slots in the cams themselves to ensure they're lined up.

The fact that somebody had the dizzy turned all the way to one end sounds like somebody has been trying to cover up a fault\incompetence

Was going to say remove rocker cover to check timing, its the only way I could do it with my 3SGTE mk3 due to suspension turret obscuring view.

Anyone know some rough ballpark figures for compression test?

Nic me old mucker! I wasnt going to stick a towel (in) the turbo. But thought i may be able to block of turbo/wastegate outlet with maybe a flat piece of wood with a damp facecloth/small towel stretched over,so you would be well clear of turbine, quick rev to see if exhaust manifold is leaky.
From a eyeing up point of view, if i was to hazzard a guess, i would say manifold and gasket are probably undisturbed originals, so hopefully they are ok.
The gasket between wastegate and downpipe was definately knackered and blowing.

The inside of down pipe looks unmarked so hopefully that means waste gate isnt catching, could also mean waste gate isnt opening tho

Matey boy from MR2oc suggested that i couldwhip rocker cover off and check cam markings in there for timing.
I put off doing that as it looked as though i might have to take inlet manifold off to get at it? or can you just undo the screws/bolts and tease it out?

As you've mentioned, the fact that tom yesterday found dizzy adjusted to one end had me thinking oh heck some clowns bodged the cam belt timing up and done a cover up.

Well at least these are non interference heads!

If wastegate isnt opening, boost pressure would be through the roof

That turbo gasket is looks like a cheap eBay solution, that won't help things, replace it with a genuine Toyota one I got mine from tcb parts the original Toyota one is a hefty thing and probably won't need changing again.

[masterbateson]

Well that TCB place doesn't seem to sell the gasket I need so I will have to do a bit of hunting.

This looks like a proper metal jobby, might ring em

TCB don't update their website- you need to call them, and yes- they will do that gasket if you ask for it

[Hez]

i know it will probably be ok but thats nothing like the oem one, just get a proper one i think fensport do them aswell if your in a pickle.
edit: they are on the tcb website , engine section 3/4 way down page.
Part number: 17279-88480

Special Offer Price: £21.15 + vat while stock last

they are even on special offer look

[masterbateson]

Thanks for finding the part but I errr well you know, I've kinda ordered that metal jobby of Eblag plus the turbo one for good measure.

Well I guess i can play guinea pig, and you can all have a laugh if it fails after a year or less.

[bobhatton]

Well weather is no good and I cant for the life of me see how you can check the timing properly with the engine in situ? you cant see bu88er all.

Heres a few pics

There are some bodgy looking painted on markings on the top of the casings but they are very rough and as you may be able to see at back off the cog(nearest head) one tooth is painted.
Both inlet and exhaust cams painted cog tooth point to 12, but cant see factory markings so no way from these previous diy markings if they are acurate.

On another note re the fuel pressure, I have no access to anything to measure fuel pressure so thats a prob, might have to get garage involved, but apparently the adaptor that you need for our cars is well expensive??

I think though as some of the symptoms suggest fuel pressure could be low that i will fit a nice new Wallbro pump, its not going to do any harm and if on the original its allegedly likely to be getting a bit tired.
Will also be handy if i want to chase some more horses at a later date.

I swapped the fuel filter fri as i got a free one, and that made a small difference so maybe that hints a pump being tired.
Anyway I've gone as far as i can today so I am off to remove some tiles from my bathroom, oh joy!!!!

You take the cam cover off to check the cams all as per the BGB

Not sure why your replacing the ebay gasket with another ebay gasket! Yes I know it isn't he same, but it's still a cheap gasket.
PLEASE don't use ebay for everything!


Given im sure you don't want to do his task again, I would get a toyota one!
It is made for the job. I wouldn't trust another ebay gasket.

Also, please do some research with the manual before delving into jobs.

Base timing.
Why not find the manual and read it? Or a quick Google will point to many a mr2 thread about how to do this with pictures.
If you did this you would know that the cam cover needs to come off to align the cam notches.
You'll also know that just the throttle body needs removing and not the whole inlet manifold to get the cam cover off. Specific queries is fine with these items, but just taking pictures of cam gears doesn't really tell or us you anything!

PLEASE look at and read the online BGB manual.

Fuel filter, did you replace the orings while you was there? Did you bolt this up to spec torque wise as opposed to just doing it up tight so it didn't leak?

As said, a wastegate that doesn't open, you'd be hitting fuel cut everytime there was load on the engine. This won't be the case. A quick google of what a wastegate does again would have told you this.

Take a step back and read the manual I say.
If anything it will give you a heap more confidence to get stuck in.

Agee with Jim but I used these gaskets .. 5 years no leaks with multiple turbos .. there 3 layer metal gaskets worked fine for me and did say only buy them if you cant get hold of oem.


The theory with the wastegate is its opening and getting stuck open .. a few posts back Paul made the observation that the actuator had a super clean portion sticking out the body that would suggest it was stuck open.
And suggested doing the foot-pump test to know for sure .

[jimGTS]

I read that earlier yeh.
Hence confused why he's now talking about it 'not opening'.

This is why I'm saying to google what a wastegate/actuator does to understand why it is and isn't in position.

When i bought the car i also bought a mongoose exhaust system amongst some other things.
The flexi section was looking a bit sad so just picked a repair section for the flexi section from MIJ exhausts in Walsall.

Repair section cost 21.50 and i got the exhaust for only 20 quid, reckon if i get it welded in for 20 quid or less I am laughing.
I'll post some pics when i get home weds.

How you getting on bud .
