Volvo 740 Turbo with "shaved" housing with a hole in it ?

yeah, I know. The hose helped I guess (the hold one) because it was
covering the whole somewhat.

So, if this is what happened---isn't this rare? I've yet to hear
about something like this.

I don't know---it doesn't seem right.
 
Thanks, Mike, I was just going to use the JB-stick and cover the whole,
but that repair sounds more sufficient. I have JB-Weld --so your
saying like buy the stick or the Kwik just just get it covered because
the regular Weld needs cure time.

Well, thanks everyone. I'll let you guys know how it runs. I've gotta
run around and I'll set it tonight.

Hopefully I'll be able to "move fast one a dime"

(as opposed to stopping on one, :P )

The metal hose is supposed to be routed so it isn't touching the turbo,
it probably got pushed in the way at some point, or the motor mounts may
be shot and allowing the motor to move around.
 
hmmm.. Yeah, someone mentioned the motor mounts previously. I'll look
into that as well.

There is a metal band on the side that holds the heater hose--it was
held in place but not securely.


Thanks for the info---oh and forgive all my misspellings. : )

Do not forget to cover the hole with a small metal disc. Otherwise you are
likely to get the epoxy inside and gum up your turbine. That thing spins
over 100,000 RPM. You don't want to unbalance it.

The hole was hidden by that aluminium pre heat hose. Looking at the
car --everything looks fine no obvious signs. I don't know, not to
jump to conclusions, but it just looks devious.

I was browsing through my Turbobricks forum and stumbled on someone's
project.that shows a turbo with a similar wear mark except that it has not
gone through. Look at the third picture from the bottom

You mean the pic with the driver seat and that' s it?

hehe, just joking--- I know which one you were referring to. :P


I put the dime on with JB Kwik and will then seal it with the regular
weld.

I'll post an updated pic when I'm done. Also let me ask you Boris, if
you might know. Have you ever changed the oil seal from the oil return
line on the turbocharger?

I gotta leak that's been like that forever (or should I say, the
previous owner had). Is it difficult? I hear about being careful not
to pinch the seal---I'm just hoping I can get to it with a rachet
extension. I haven't tried yet, but I want to try tomorrow.

No I have not (yet) Maybe someone here knows, else visit Turbobricks
Maintenance and nonperformance section of the forum and ask there. You do

Actually someone here said it was possible---I'm just trying to get
some details.

thanks, I'll check there, too.
 
Well, I drove it right now--just to see--I haven't set the regular Weld
yet. But just to see, and it's helped alot! However, when I go into
boost near the back of the car I still hear the flutter---what it
sounds like ( only when going into yellow turbo on the guage) is what
sounds like is a rapid drum roll sound ---it's like light rapid
rain---like a snare drum roll rapidly with a wire brush.

Maybe an exhaust leak or something on the catalytic converter ?
muffler ? I don't smell anything or exhaust fumes ?

BTW, there is light smoke smell on the engine. I think the oil trap is
blocked. I pulled the oil cap loose and it jumps around. Who knows
when that thing has been cleaned/changed.

Maybe that's why I got the oil leak on the oil return pipe.

The real fun is when the old gasket sticks firmly to the turbo and you
have to spend an hour scraping it off with a razor blade. Usually it's
got enough oil soak to come off, once I had it stick very firmly, though
thankfully the turbo was on the bench at the time.
