Hi,
sorry I have been having a small problem with my smoke and its the oil going into my intake manifold from the breather tube the one that goes on to the 3 way rubber pipe and from their a tube goes into the air cleaner tube I dont think this is right the part about the rubber tube going into the air cleaner tube

I would realy apriciate if anyone could take a picture of their air cleaner and the hose that goes to the back of it i dont think mines right

Thanks a bunch, Jeremy

If I understand you correctly, you have oil going into your air cleaner from the tube that comes from your vacuum pump, which would indicate a split/leaking vacuum pump diaphragm. Those older style pumps are fairly cheap and easy too rebuild.

A picture would be worth a lot of words in this case. Not sure what you mean by the 3 way rubber pipe. I think there should be one breather tube coming from the valve cover and going into the intake manifold. There also may be a clear plastic or white breather tube coming from the vacuum pump on the front of the engine and going into the air cleaner. But it could be that the earlier 616 engines have a different set up that I'm not familiar with.

75 240D has an oil bath air cleaner.

I recall a line from the breather to the air cleaner, and a line from the vacuum pump to the intake plenum. I do not recall any 3 way device.

may be thats the problem then there should not be any 3 way pipe

the breather hose goes on to a 3 way rubber joint that sits on top of the intake manifold the tube from the breather hose fits on the top of the joint and from the 2nd hole in the 3 way joint a pipe goes into the air filter

could someone post a picture of the part of the air filter that goes on to the intake manifold please

thanks jeremy

From Russian EPC site 115.117. Which one of the setups looks like yours?

Also do you have a W115.117 or a W115.116?

Hi,
I cant say it looks like any of em mostly like the 3rd one out of the 5th
these stupid mechanics in srilanka think its best not to have air filter but after we found out we put one in today but i cant understand the pipe 176 in the diagram, does this just plug in to the intake manifold because they had removed the rubber pipe 323 in the other link and we had to put a normal fairly large short hose to connect the air cleaner with the intake manifold and made a small hole for the pipe 176 to plug in it is this correct??

Thanks Jeremy Brett

I cannot find any pics as to where 176 goes.

I have been looking for pics and the 1st thumb I think is what is important; it is the Hose/tubing that goes to the Pneumatic Governor; #4 in the pic. If that is not in the correct place I would suspect that it would not function correctly.

Next would be the #1 tubing/hose that goes to the inlet of the Vacuum Pump. You can see where it goes on the Intake Manifold but my guess is it does not matter where it goes as long as it is sealed good and the Vacuum Pump Diaphragm is not ruptured. However I think it would be nice if it was not connected to close to the Crank Case Breather hose so it would not pull in any Oil from that into the Vacuum Pump.

I do not think it matters very much where the Crank Case Breather hose goes. Some Pics showed a tube with a nipple on it between the Air Filter and #5 in the 1st thumb (this is the part that has the Butter Fly Valve in it).
#2 pic is showing where the tubing/hose from the Vacuum Pump goes on the Intake Manifold.
#3 shows a hose going into the top front of the Manifold with the Vacuum Pump tubing/hose below it on the side of the Manifold. I do not know if
this is the Crank Case Breather Holse or not.

Since the Governor uses Manifold Vacuum I do not think it is the best idea to pipe it into the Intake Manifold directly as shown in Pic #3. You would think that it would be possible for the Crank Case Pressure on an old Engine to counter part of the Vacuum Created by the Butterfly Valve and I believe that could alter the performance of the Governor. But, that is a guess based on how the Governor works.

I think I would prefer the Breather Hose to go on Item #323 in the 3rd diagram (or item #83 in the 4th diagram) at that lower nipple on that part. See site below:

Right, then we have lost item #323 not us but these stupid mechanics in Srilanka had, anyways they suggest we get a rubber big hose (short though) big enough to fit into the intake manifold and the air cleaner to join em together then we make a hole in the middle of the rubber hose and stick the return breather hose into it do you think this is retarded and wont work well and that we should get one or should we use it the way it is

Thanks Jeremy Brett

It could be that over the years the #323 being rubber rotted away or cracke and was replaced with a straight hose.
Just cutting a hole in the larger hose and shoving the smaller hose in is a bad idea unless you can figure some way to seal it and keep it from falling out (eve with a tight fit it will loosen later). If it is not sealed you will pull dirt in.

If part #317 is steel tubing you could put a hole in it and have a short piece pf pipe with an outside diameter that matches the inside diameter of the Blow By Hose welded to it.

If they are determined to poke a hole in something they could poke a hole in the air inlet portion of the Air Filter (red arrow) before it goes through the filter and run the Hose into there.
Being an Oil Bath type Air Filter the Crank Case Vapor will hot harm it.

Don't be too hard on the Mechanics there I have seen some bone headed things done right here by Mechanics who were supposed to be well trained.

I was a civilian worker at a Naval Ship Yard were they sent all the Mechanics to a 3 hour class on the proper way to plug up hoses, tubes, and pipes. Stated many many times in the class was "do not stuff a rag into the opening".

The result was that a few weeks after this class a Rag that had been stuffed into a Pipe was sucked into the Oil Pump of a Mine Sweeper Engine (a small ship) that we had Rebuilt.

Hi,
I am very sorry I could not reply during the last few days I had managed to get hold of an original corrector to connect the intake manifold on to the air cleaner
and everything is fine now thanks,
I have just one more question our car it has some rust and it a good idea to purchase a welding machine to do welding our self is it safe for a 16 year old to do electric welding
Thanks Jeremy Brett

I can see Welding the Structural parts of the Vehicle but the exterior Body Parts are often too thin to be easily Welded.

However, there is a body repair section with threads (I have not looked into that section) on body repair in our Forum.

As for a 16 year old and safety:
My first what I call a real job (part-time though) at 16 years old was working in a Welding shop where we welded Mini-Bike Frames under contract for a place that assembled the Mini-Bikes.
But, spent 2 day of unpaid "On The Job Training" by the Boss of the shop until he felt I was good enough to pay me.

Safety is kind of a personality issue; regardless of age some people are safer than others. You know your 16 year old best.

If you do a reasonable amount of (Arc) welding at some point you are going to get burned. Nothing bad; but the splatter easily burns through Fabric (wear extra eye protection; even under the Welding Helmet as hot particles can come up inside of the Helmet). Not to mention good heavy Leather Gloves, Leather Apron and Leather Boots (hot sparks fall inside of shoes and burn your feet).

Due to the Electricity involved there are Electrical safety issues.
Due to the Heat involved there are Fire Prevention issues.

I have never used one of the Flux Core type Welders but I am guessing that they do not produce as much hot metal splatter as an Arc Welder does.

Next who ever is going to use the Welder needs to practice on some scrap metal before doing the job.

The Frame on my Computer Chair Broke last week and I Arc Welded it back together. It worked but I did an awful job. I have not welded anything for over 7 years and am extremely out of practice.

Do they have any sort of Industrial Training over there? After working on the job I went to a Welding Class at the local City College to learn more about it.

I am 16 years old and its my dad's car any ways they have no training for arc welding here but is it possible to get an electric shock if you touch the electrodes of the arc welder and can you cut metal with the arc welder by turning up the voltage also how would i bend the metal what
is the best thing for me to do

Thanks Jeremy Brett
