[R129 SL] automatic gear update soap 3

[Jan Kuylaars]

Today I drove to my gearbox expert. He told me that he drove last
weekend several times in the car and most of the oil was burned.
So it should be no problem to increase the distance to let all the oil
burn out. I can take my car this week to drive it home.
The costs are 1425 euros total including taxes and labor:
Build out and in the gearbox, renew the pump with a peace of the housing
with bearing and oil seal, filter, gasket, oil and one friction ring.
Rebuild the gearbox and control, make a alignment to correct the
shifting at 50-60 km/hour and several test drive's .
Tomorrow its last test-drive. The rest of the gearbox was OK.
 
So the only pain I have is from the first 350 euros for nothing.
 
And then to know that some folks are buying an other car for 1500 euros
to drive a other year.
 
Jan the next week  flying Dutchmen.

Hi Jan,
I am an electrical, data, security and building services engineer.  I
have a number of acquaintances who are expert chemists ( they analyse
stuff we find in buildings - I test PCB's) so I can find out most things
about chemical reactions and agents if required.  
 
It sounds as though the mechanic tipped a lot of oil in the heat shield
when the gearbox was removed, if the reconditioned gearbox was not
leaking oil.  I would remove the heat shield (if it is easily possible),
and the 'asbestos' wrap (most likely 'rockwool'  - but check), and find
out how the oil found it's way in there!  Talk to the mechanic as well.
The insulation will most likely need to be replaced as it is very
difficult to remove oil from absorbent 'rockwool' insulation products -
it seems to stay there forever and it smokes/ smells for an eternity.
 
If you need any chemical stuff looked at, let me know and I will call my
'boffin chemistry associate - Len'  and he will be able to sort
something out.
 
First day of spring in about a 8 days so we are getting a bit warmer at
the moment - I  have this wretched influenza virus, and to top it off,
my PC was infected with a Trojan cluster virus in the system 32 files
(we both have the virus!)  I managed to contain the PC virus and killed
about 10 of the clusters, but it took 5 days to clear the system of the
rest.  I should have wiped the C drive and re-loaded windows XP as it
would have been quicker, and I have my data backed up. Look out for this
virus, as I understand that Norton and AVG do not have patches as yet
(have both on my PC) but understand that nod32 antivirus has a patch.  
 
Have a great day, and hope the car problem can be resolved.  
 
Kind Regards, Peter S.

Peter Shelton, you are a expert on chemicals, can you or someone else
give me advice?
 
My gearbox is repaired, placed back under the car, and is shifting well,
and no oil loose.
But my car is not yet home.
 
Why? After de expert had mounted the gearbox he is going to test-drive.
Driving one street he was stopped at the traffic light and some seconds
later the car was full of smoke.
So he drove back the the garage and put the car back on the bridge to
see if there was a leak.
There was no leak, the gearbox was dry, but the oil from the defect
leaking was flown inside the heat shield and the exhaust pipe.
So, the asbestos cloth between the heat shield is filled with oil, and
when the exhaust pipe become warm, the oil start to smoke.
He drove some days small distance and the smoke become less, but he is
afraid that when I drive my car to my home there is
a possibility that the oil will go burning and set my car in fire.
 
What can I do?
 
Take the risk and drive some distance and till there comes smoke and
cool of the exhaust and wait with a fire-ex.....
Or dissemble the exhaust and heat up the exhaust with a gas burner  away
from the car till the oil is burned out?
Or is there a chemical what will solve this problem by spreading it into
the heat shields?
 
What is wise?
 
 
Met vriendelijke groeten,
