[diesel_mercedes] Re: Why Air Cooling ?

 

Here's my take on air cooled engines from my few years of flying small planes (air cooled engines) after I got my pilot's license. The advantage of air cooled engines is, yes, their simplicity which is important as far as weight and reliability are concerned - no coolant to carry around and leak out and no pumps to fail. The downside is shock cooling and cabin heat. When you pull the throttle to descend, the engine starts putting out much less heat while the air still flows through the cooling fins. The result is rapid shock cooling of the engine which results in stresses and increased wear. The other disadvantage is cabin heat. Putting aside the uncomfortable fact that the heat output is variable with the engine output, there is the danger of carbon monoxide poisoning given that there is only a thin wall of steel between the cabin air and the exhaust. Unfortunately, numerous crashes can be traced to the soporific effects of CO.

For cars, liquid cooling offers much better heating, consistent engine temperatures resulting in (theoretically) longer engine life, and quiter running as the water jacket deadens some of the sound.

Re: [diesel_mercedes] I LOVE Pick-A-Part !

 

Uh.... 
       ... WHERE  is   that   P-A-P   yard ?

Saturday morning Tom and headed out to the local P-A-P yard with special tools in hand and my regular 5 gallon bucket o' tools to find some un bent tie rods (dang tow truck !) for the Euro Station Wagon I'm building for my sweet , I quickly found a W-123 with no front wheels and tried the <magic> Chinese tool ~ it popped the tie rods loose in a minute or less , NO DAMAGE to the rubber dust boots ! .

Tom wandered 'round looking for elusive W-126 parts and came back to report some old gasser wagon was nearby , I went to have a look and discovered a gray market 280TE (M-110 engine) that still had the front European bumper on it so I grabbed that , prolly will install it to my '84 Diesel Coupe .

I also found , in a W-124 , a _Japanese_ made Mercedes logoed AM/FM/Cassette radio that has the _same_ electrical plugs as our beloved W-116 ,W-123 & W-126's do , I waffled about buying it , Tom (the Electronical Genious) read the manufacturer's labels and asked me to look closely at it ~ it turns out to have THREE bands , one is a weather band wow ! he bought it for $17.00 , I prolly should have bought it for my truck but now I know there's yet another good DIN sized radio to look out for .

Oddly , the front of the radio doesn't mention the weather band . it has electronic tuning and so should be a good one .

It's been warming up a bit here , 44° last night but it was 80 + ° in the yard yesterday , I sweated out too much and nearly passed out in the yard .

No local PAP places?  If you will put it in yourself, try car-parts.com the have a search system for wrecking yards.  I have one that I'll be removing in a month or so, but I'm in NY and shipping would probably cost as much as having a franchise install it.

Hi,

I recently had all four tie rods and both ball joints replaced by my trusty Euro specialty mechanic here in Metrowest, MA. He replaced all of that, the steering box and idler arm rebuilt, along with five new glow plugs in less than 8 hours of shop time. If you look at

http://groups.yahoo.com/group/diesel_mercedes/photos/album/796370990/pic/list

you'll see what I found about a year ago when I had one of the ball joints replaced....

and then look here for the manifest of parts I just put into it:

http://groups.yahoo.com/group/diesel_mercedes/photos/album/614318898/pic/1349541752/view?picmode=&mode=tn&order=ordinal&start=1&count=20&dir=asc

Not sure what's holding your shop up, but it shouldn't take that long unless for some reason they can't get the parts. (We had no problem ordering parts).

Hope this is somehow helpful...mine is 1984 300SD

Still waiting for it to be done mechanic has no news but that he is working on it is it that difficult any special tools or procedures required. I know he was replacing tie rods, upper control arms, lower ball joints and shocks.

You have to be careful with your choice of mechanic, get the wrong one and they'll have you by the balls.  You should really get a better reason for the delay.  One tactic, get one of your biggest, meanest looking friends and stop by to inquire exactly what the delay is.

Back in the day, BMW imported a strange little vehicle they called the Isetta.  It was driven by a (350? 650?) parallel twin motorcycle engine that had sodium cooled two piece valves, and as I recall, the reason that most of the Isettas failed was that valve broke in two and destroyed the motor.  Bunch of college kids I was hanging with at the time, one of whom owned an Isetta, found a way to near enough directly replace the BMW valve with a very (dimensionally) similar Chevy six valve, which would last forever.  Don't know if that ever caught on with Isetta crowd.  Or even if there was an Isetta crowd...

Using .35 CENT , two - piece valves then leaning out the fuel mixture WAAYYY below it's design parameters will do that...

There is an Isetta crowd.  Look  at the microcars - minicars group.  It's frequently entertaining.

I never owned one, fixed a few.  At that time I was pushing a Fiat 600 with a 600D engine.  Raced it , never broke the 600D engine , but I had to stop running the 600 Engine when it broke the top ring on one cylinder.  The first fix was a spring clipon the dipstick to keep the blowby from blowing it out of the engine.  Finally gave up when the pieces of the ring worked their way to the top of the piston and were being hammered into the cylinder head.

all the years in my youth (when, I'd run 'em red line all the time) I never
sucked a valve.
I adjusted periodically, and, probably ran a little rich.
Also ran external oil coolers and fans.
