View Full Version : Turbo help !!
Right been trying to sort my car out today as it doesnt seem 100% right,
Heres my problem, Where the actuator bar joints onto the turbo the swinging arm thing. theres alot of movement in it up, down, left and right is this normal or what is the problem???
I know it should swing left and right from a fixed pivot point but its not a fixed point.
Please dont tell me the turbos gone :(
Joe
It's a gate, so it will open and close, there shouldn't be to much movement up and down.
Is it not making boost? Can you hear the turbo spool up?
no its not making boost at all :( and that gate arm i can pull up about 1mm
not sure about hearing the turbo as the exhaust is mega loud.

The penny vavle has come of and is in your exhaust some where im affraid :(
hmmm easy fix??
might it still be on there just not very tight as i cant pull it out
I'd unbolt the down pipe elbow and have a look at the gate.
Get some pics and a vid of the movement.

The bush on the wastegate is worn, depending on the wear, you will suffer (low) boost issues.
So have you bought a low compression XE with a windmill in the manifold then? lol

Not anymore Joe, i have bought it.
the thing with the gate there is that much movement in it that when its bolted up in the correct position the actuator cant move it as it seizes.
I couldnt even move it with a screwdriver.
yes i have craig but starting to think i shouldnt have :(
arhhh crap rick whats wrong with yours??
You cant move it with a screwdriver? It should be free to open.

Far from saying I told you so (I didnt) but thats the risk with stuff like 100+k motors 7 paying over the odds for them. Obviously it's likely it is fixable.
I'd ask on MIG see if anyone has a LET KKK turbo for spares.

Nothing, i wanted a spare.
i can move it when its not bolted to the actuator
But when its on the actuator bar i cant move it as theres to much movement in the arm
Might be the actuator then.. as that will push it open...
na the actuator moves fine all be it the bar is bent a little (comman problem ive heard)
its defo the gate arm thing thats at fault
Take the elbow off and see if you can move the arm.
i can move the arm now its off the actuator,
But when it was bolted up on the actuator bar it wouldnt move. i unbolted the bar left the arm on it just not bolted up and the actuator moved fine.
its the up and down movement on the arm thats locking it when bolted to the bar

If the part is available, I can't see why you or someone can't do it on a bench.
going to rip the turbo off tomorrow me thinks,
undo the cast downpipe part and look first, if it gone walkies theres ya issue, saves ripping it all off
Fire some pics up Joe
Use your phone with that app make things easier as you don't need your pc to post pics
I said that a page and bit back...
i cant now lol
tomorrow i will thou. will get a prohect thread to me thinks
i knoes benn, just reinforcing the point :gayer:
if turbos naff'd what could i replace it with and would it be alot of work?
Im talking none KKK
go for a t3 hybrid and a mani off ebay, theyre £199 for the mani.
dont i need manage ment for a differant turbo?
right got 4 of the 6 down pipe bolts off the one at the to is being protected by the fan cowling and the bottom one is hidden by the oil breather :(
ive given up for 10 mins.
on a good note its got a coscast head :)
right all bolts out bar the one at the back at the bottom by the oil breather.
how on earth am i ment to undo that??? any ideas people?
With a spanner lol
No on a serious note i cant remember off top of my head.
It does sound like a penny valve issue to me...
:( im going back out to try and its a 6mm allen
Are you unbolting turbo off? Or downpipe elbow?
Sorry mate cant help you as i cant remember.
Post pics of what you find. Also get a good res picture of around penny valve for cracks etc.
thats ok mate
given up again :(
if it wasent boosting and you couldent open the gate this becouse the actuater wouldent allow it why not take off the actuator and take it out and see if it boosts just dont kill it
its defo the gate thats funked, still cant get the last bolt out thou
Right turbo is off and luckly the penny valve is still on :)
All thats wrong is there is to much play in the arm so its going to need a new one.
Anyone got any reccomendations on where to send it?
let me get the photo bucket app and i will get some, turbos off and sat in my hall lol
The arm that the actuator bolts to

See the link in my sig - 99.9% of the let turbos we see have excessive play in the wastgate arm bush. If your running an uprated actuator it will make it worse.
Just who i was hoping to reply lol
How much roughtly would you think it would cost to get the wastegate bush replaced? and a new actuator as the bar is bent
Going to ring your place tomorrow anyway to arrange it getting fixed
Glad you've found the prob.
yea im going with excessive play in the wastegate bushes,
Still got to solve why there isnt any water getting to my Heater matrix thou :(
Could be blocked iv had that before
Heater matrix blocked I HAVE had that before lol
well took both the pipes off and blasted a hose down them and it come out the other pipe

Do you mean it isntgetting hot in the cabin?
its not getting hot in the cabin and if i squeeze the pipes coming off the matrix there not hot :(
the joys of LET ownership :(

But i knew i would have teething problems but oh well the main parts are all there and working so i now have my time to tidy it up :) then aim is more power prob after a year of ownership.
