I find in 1st and 2nd from 2500rpm to 5000rpm the car flies up it, in 3rd 4th 5th then car hesitates going from 2500 up. and when i took off the line going from the turbo to the IP to look at setting up a boost gauge there was oil in that line, is that normal? :shock:
-
Depends on how much oil is in there.
If you take the top of the LDA off you'll probably find that it's full of oil.
You should take the intake boot off and check the turbo for play.
-
will do that tomorrow, i find when I drive the car hard...4500rpm down the highway for 5 minutes it smells strong like burnt oil/ carbon burning...

I think that's normal. I get that too a bit. it smells a bit like things are getting hot and i think that's all it really is ... stuff getting hot. cooking what ever organic material is on there.
-
ok thats good, i though i was on my way to frying another motor...
-
Ok is there supose to be play on the intake part of the turbo? If so how much? if not then I guess its f*cked...there is about 1/8"inch of play up and down on it...and tere is a bit of oil inside there. :shock:
-
I would say you wouldnt want quit that much. I am more into the bigger truck stuff but 1/16 up and down but the in and out is what I worry about the most.
-
You should start looking for a replacement turbo. It's getting there. I wouldn't say you've reached a critical state yet though. If you plan to rebuild it, do it asap before it hits the housing, then it's no good.
Does your car have the regular style of wastegate control or VWs crazy idea of limiting it with a vacuum switch? You can tell simply by looking for any vacuum lines coming off the wastegate leading to the airbox area.

To be honest i don't know... heres some pictures lol :lol:

just rebuild it.. or buy a good used one.. t3's are easy to come across.. that is just a normal t3 right?
-
It's probably a K03 actually (AAZ engine), and it does in fact have the dreaded vacuum-actuated wastegate defeater designed to limit turbo action for emission reasons.
The FAQ ("make your 1.9 faster" thread) covers off what to do.... although I don't think it mentions pulling the vaccum hose off the back of the wastegate once you've disabled the throttle switches etc.
I believe venting to atmosphere makes the wastegate work properly, as opposed to vacuum... Tyler: do you know for sure?
-
You have VWs crazy boost limiting idea.

Cut the hose at the arrow. Plug up the A end of the hose and leave the B end open to atmosphere.
This will give you boost when the engine needs it, not when VW thinks you should have it.
This will accelerate the wear on your turbo though.
DISCLAIMER
Get someone to verify what I just said. I hate turbos and could be wrong

Tyler: do you know for sure?
I'll second it likely being a K03.
Vince: I'm not sure. I had one on the workbench today and using compressed air it seemed to function as it should with the mod done in my picture above.

you also have an exhaust leak.. notice that hole right below your flex coupling?

Sharp eyes. :wink:
Is it just me, or is CSI:Engine Compartment Pictures one of the funnest games ever??!!!!
-
eh, if i didnt have my glasses on, i wouldnt even be able to tell you what kinda car it was, let alone if it has an engine in it or not. lol.. and yes, CSI is pretty fun..
also catlin.. did you check your fuel filter yet? my car does the same thing if my filter is gettin plugged. pulls like a mother through 3rd gear, but then the boost drops off half way through 4th and is non existent in 5th..
-
It is a K03 turbo, i know there is an exhaust leak lol, I have a new Doww pipe for it. I want a bit more boost for travelling on the highway. i drained the fuel filter and its clear. There is a lever from the turbo to the waste gate, how do i modify that to get more power?
-
you cant see how well it flows just by draining the fuel. the fuel that comes out of mine is always red, even if the filter is clogged or not. i would still check the filter.
-
the fuel is following fine. i think the IP is going...i'll need a giles pump :twisted:
-
Tyler - You said to leave B to the atmosphere, will changing altitudes affect that drastically, I tend to go up into the Appalachian Mountain range alot.

Isn;t the red fuel for "Offroad Use Only" :lol:
-
nah, its just alot easier to obtain than ULSD. and 90% of the time my dad or grandpa have a pretty good surplus of the stuff sitting around. my grandpas boat has a 8V71 in it, and it likes red fuel.
-
Up and down play on the turbo isn't very dangerous if there isn't too much of it. Longitudinal play, however will instantly mean it's going soon.
Even 1/5th of a mm will indicate a worn bearing.
But, like it was said already, replacements are pretty cheap.
Too bad the turbo can be a pain to replace with the engine in place :roll:
