if its a stuck wastegate penny

then take the exhaust off the back and the actuatir and have a lookk

you should just be able to see it and it should move freely by moving it where the actuator connects

if not just try and give it a little help witha screw driver in the back and try and free it up

jamesers20004x4

ill have a look tomorrow, nice slow drive home from work for me tonight!!!!

fingers X'sed it dont need a new turbo! say it is the wastgate thats fooked can it just be rebuilt to replace to keep costs down or not?

cheers

the wastegate is in the exhaust housing

so if you carnt free it you can just get another housing

jamesers20004x4

ok,

gone out and had a look and cant really see anything of concearn.

but...

somthing I hadnt noticed before so dont know if its new or not.

hard to explain where, got pics cant get them on PC at work

you know where the oil feed goes to the turbo on the top in the middle, on the side of the turbo (as you stand in front of car, bonnet up on the left hand side) is a hole? has a thread in it. looks like somthing should screw into it?

anyone know what it is??

xr4x4rs

iTrader: (5)

is the turbo water cooled?

as you would have at the top the oil feed the under oil return

on the sides of teh core would be where the water pipes go

if theres another hole at the top could be the lambda sensor hole but you would of noticed this straight away

can u get a pic?

jamesers20004x4

tryig to as we speak!!! 10 mins!!!

jamesers20004x4

cant get the pics off my fone onto my PC at work!!

no one has email from their fone here!!!

take the actuator rod off and see it you can move that shaft that the actiator rod goes on

jamesers20004x4

now i think the turb has gone!!!!!!!

just been out started it up reved it a bit from the throttle in the engine bay and there is a horriblr rattle comming from the turbo when the revs a reducing

not noticed that before! if the turb was gone id expect white smoke from the exaughst but there is nothing at all from the pipe!!

any other symptoms of a blown turb??

jamesers20004x4

PS will try that tomorrow with the actuator!

Your wastegate arm has 99% certainly snapped mate. take teh exhaust downpipe off and pear in teh back mate. Unless teh actuator has broken?

Billabong

Rattle or screeching? If a rattle, that *could* be the wastegate if there isn't enough pre-load on the actuator. Or the wastegate arm could have bent, which could cause both symptoms (lack of boost and rattle, as it won't be seating properly).

EDIT: to slow

Undue the down pipe and have a look like Stu has said odds on hes right though.


If its not that which i am sure it will be, take the air filter hose off the front of the turbo. Have a look at the blades and the wiggle the shaft to see if there is any movement on the bearing if you cant see anything.

My old turbo died this way, i had no smoke and was still giving me 2 psi of boost.

jamesers20004x4

deffo a rattle on down revs only.

the actuator amr is straight and stiff! (no sexual puns please )

where is the wastegate arm located? cos everything i can see on the outside is ok?

how do i diagnose a broke actuator?

is this gonna cost a lot

cheers for all the help guys, its much appreciated, i know i dont come on here much anymore but you comments realy help.

thanks again

the wastegate arm is where the end of the actuator goes onto

should just be a split in

but take the downpipe off and have a look inside the turbo and hope that if the penny has snapped its gone down your exhaust and not into the exhaust blades of the turbo

RIGHT,

looks like im getting my hand dirty tomorrow!

will do all of the above tommorow and post my findings!!

Put your finger on teh wastegate arm at the end of teh actuator and see if thats what is rattling. Dont burn yourself though mate.

If it is, unhook it. If the arm moves nearer to teh actuator than it was, then its very likely the wastegate penny has actually fallen off and is in your downpipe now.

jamesers20004x4

OK,

the wastgate arm moves about 1mm back towards the actuator. It defo feels like the penny is still attached, can here it, sounds like flicking your finger out the to of a glass bottle. if you know what i mean!!!

how do i look inside from the exaughst end? unbolted it from the turbo but cant move it enough to see inside. the studs that hold the bracket on are in the way and i cant get them off???

cheers

iTrader: (5)

does it move any other way as it should be free moving quite a fair bit

too look inside you ned to remove your downpipe and push it out the way it will move out the way enough for you to look inside the turbo

jamesers20004x4

compleyely loose!

will try again tonmove the down pipe!!

5 mins!

jamesers20004x4

right gave it a bit of welly and can now see inside!! wastegate arm ok, penny still attached but its is slightly loose on the arm. also it does spin around as well.

never seen in there before so dont know if that normal?

how do i diagnose a broke actuator? without puttin a new one on??

cheers

Take the big hose off the front of the turbo, look and the blades, are they OK?

When you try and spin the spindle with you fingers does it run freely for a second or two?

Carlsworth

Very much doubt its anything to do with the turbo unit

bit of a stange one though....

what exactly happened..
ie: driving, came on boost, lost turbo...


what about split pipes relating to the turbo..take it youve checked all pipes

jamesers20004x4

first thing i did, hose off front and it has 1mm ish movement and spins freely for at least a couple of secs.


what else could be causing this problem??

by the way just remembered, on drive home the other night from work after the morning it first happened. had nothing like in the morning but every now and agian it would start boosting again? would have my foot flat on the floor to try and get some speed up have to brake take my foot all the way off the throttle and when i put it back the boost had returned?? bit shocked cos i wernt expecting it took my foot off agian put it back and nothing??

anyone??

on the road of the actuator

is it tight to pull out?

or can you move the rod in and out freely

jamesers20004x4

rods totally stiff, can bearly move it!! thats normal though? right?

jamesers20004x4

yes, checked the boost hosing. all ok cannot see any holes/slits in any of them. all blue samco's.

thinking i might just put it back togehter and go for drive! see its its fixed itself!!! lol

no decent tuners round here to take it to either! effin Rs's whod have one huh!

alan rainbow

take the down pipe off and stop fookin about maybe the exhaust turbine as snaped off

jamesers20004x4

if the turbine has snapped wouldnt get intermittant boost would I?

wastegate is ok, actuator is ok (from what i can tell) all hoses are ok checked everything I can think of so im not fookin about just looking for advice!!

Carlsworth

bizarre...

it is "possible" (unlikely) the shaft has split/cracked/damaged in a way that sometimes it catches and works, and other times it doesnt..


i really dont think its down to the turbo though....

if you want, i can be stripped and inspected for minimal charge...

your I/cooler has a split in it (take it off and fill it with some water and you'll see where the air leaking!

jamesers20004x4

ok finally sussed it!!!

got fed up with it all apart so decided to put it all back together and turn the boost right up, thinking maybe weak actuator. went for a drive and had bout 4psi boost!

but...

if i really pushed on the throttle (and i mean its to the floor but pushing still more!) i got a little more??

went home checked the throttle cable and its fucking loose!!

was getting boost but cos the throttle cable was so loose didnt get enough revs!!


im I the tosser of the year or what!!!

panic over broke turbos....... OVER!

Stu @ M Developments

If what your saying is that you can unhook teh actuator rod from teh wastegate pin and teh gate is then free to move TOWARDS teh actuator, then that is incorrect and is 100% the reason for your lack of boost. But im unsure if thats what your suggesting as everyone else seem happy your turbo is fine, so maybe i am missunderstanding your description.

The wastegate pin should be at lest 3mm TOO Far away for the actuator to hook over it so it needs shortening about 5 turns.

The question is, how has your actuator extended itself?
