It's on to exhaust & turbo repair today, as earlier I found the whole
exhaust system loose and/or broken.

Be thankful that you don't have the '85 CA 300D w/ the CAT, as that
extra part in the system, between the exhaust manifold and the turbo,
allows more chance of movement of all the parts.

Last week I tried to tighten up the system, and found the exhaust down
pipe had sheared off, so I had that repaired, and while trying to
tighten up the turbo mount, broke a bolt off in the manifold, which
didn't want to come out with the usual drilling and 'easy-outs'. The
shaking seemed about the same as before, yet I heard more noise from
under the hood, and when I started pulling the turbo et al, I found a
broken turbo bracket, and then the EGR tube, and later the end of the
CAT had sheared too. When everything was pulled, I noticed many of the
supports were loose.

Luckily, I do have another set of parts I pulled from a parts car years
ago, as well as a federal setup from Brian's old engine. Unfortunatly,
the federal system won't fit w/ the '85 CA, A/C hose routes, yet if
there's issues in the future I may switch out the A/C and exhaust system
to the standard federal setup.

Since it's all apart, it makes since to rebuild the turbo before
reinstalling.

Anyway, I better get out there before the heat rolls in.

Re: [diesel_mercedes] On returning home: Going back to R12?

 

I would definitely NOT change back due to the price  of R-12
Keep a can of 134 and a small charge hose with you.  Shoot a little in it if needed.  Freon WITH stop leak is a waste of money. But there is a sealant that works well as long as it isn't the seals in the compressor going bad.  It cost around $25-$30 at local auto parts stores.  I don't remember the name but it is a small can, about 4 ounces or so. Instructions say Add it then immediately add some freon to clean the charge valve so it doesn't get sealed in place. The little hose that comes with the sealant works great to keep in the car to add a shot of freon when needed.

I  have made it through most the Houston summer on converted R134 AC.  But as summer draws down my AC is flagging in my 300CD coupe and AC recharge is in my future.

I am contemplating a return to the original R12 and wonder about the merits of going back.  What is involved in a rededication to the original?  Is it worth it in terms of cooling performance?

Anybody gone back homw again?
