Re: FJ T03 'stuck'?!

[Mark]

Had no time yet to investigate, during this week- thanks for the 
pointer, since I was going to skip right past that observation check, 
launching into unbolting things this w/end and no doubt someone would 
have wondered over on Sat arvo and said the same thing and I would have 
gone DOH!

sorry if you've already done this
I came in half way through this thread
but have you taken the piping from the compressor mouth and tried 
spinning
the turbo by hand? perhaps oil build up in the core has 'congealed' or
whatever the term for it is
if it does spin smoothly and easily then chances are the oil has dried 
out
and gone all crusty (hehe yes I know, such accurate termanology"

Prior to this recent problem I had the battery diconnected and removed
from the
car, so I don;t know if that affects things - COnsidering it starts, 
idles
will
run fine up to 1,800 I really suspect it is purely a non-spinning 
turbo,
tho
I'll give it a try. I have a laptop and haltech software so I'll also 
run
the
engine data page do a datalog to see what comes up.

Quoting James Hughes <[EMAIL PROTECTED]>:

try unpluging your computer for about 20 secs and plug it back in 
again
and
see if that helps

Howdy List,

Well I went to get the 'disability in the garage' (as my wife calls 
it
now)

out for an emergency unreg'd drive to work since she temporarily 
lost
the
keys to the parts car...
Anyways, my stuck turbo syndrome strikes again, only this time it
didn't
unstick itself  - stuffed bearings or all carboned up are my guess.
Symptoms are engine starts and runs fine... up to ~1,800 rpm then 
just
hits

a brick wall if driving or surges on idle with light accel. If I 
kick
it in

the guts enough it will rev to 3-4k with the telltale turbo whine 
(hey
its

spinning!) but will idle down and won't go over 1800 again without 
boot
fulls from right foot.

What happened last time was the whine came back and stayed and all 
was
well

- and it struck me at that precise moment "oh the turbo wasn't
spinning,
impeding gas flow and so no go - tho' when it refused to drive above
1800
it does just go pretty dead with nothing, almost like ECU is cutting
for
not getting right MAP reading or something? So I need to remove 
turbo
and
inspect, fiddle see how free it is (not very!) and for from
there...what
are the gaskets required when I take it off, can I buy, make or
customise
something or do I get something for Stuart Wilkins Rally etc.

Having a turbo recently that lost it timing (due to worn keyway on 
the
end

of the crank) displaying some of the above could it be some major
mishap
with dissy or computer? The lack of turbo whine is bit of a give 
away,
but

I'm not to sure how noisy it was under 2,5-3,000 rpm which when I
usually
hear it - and as above it will eventually spin with revs.

TIA for any pointers,

PS any good t3 or Fj suitable turbos 4sale?

Mark
