"Ether", use and abuse. *Flame suit on*

[whunter]

Hello Everyone
#A. I am a professional mechanic.
#B. My average use of ether = three cans per year; two are used to clean special parts.
#C. My personal vehicle repair average = 980 too 1700 vehicles per year.

I have used ether on my 300SD twice, following is the description.
Note: My air intake system is OEM.
#1. Open the hood.
#2. Look at the front of the radiator.
#3. Locate the air intake pick-up tube.
#4. Give the air intake pick-up tube a one second shot of ether.
#5. Walk around, get in and start the engine.

You will please note that this way; it is almost impossible to feed excess ether to the engine, the excess will run back out, the weak ether vapor will last only a couple of revolutions.
This will not strip the cylinders.
When done correctly; it would not damage a diesel.
Ether is only to boost start the engine, not run the engine.
Ether vapor is what the engine wants; not liquid ether.
I have considered making a video of how to use ether correctly on a diesel, there are several videos on the market.

Note I try to see humor in all situations.
I qualified my answer; for the goof that I watched trying to start an Audi diesel (running #2 that jelled), he used three ether cans; straight in the turbo body, witnessed him spray half a can into the turbo body then puncture all three cans to dump the remaining liquid in, even after I warned him.

He paid when the front end lifted and oil started oozing out from under the engine, I could not stop laughing as I drove away.
Natural law does not forgive an idiot; the repercussions can be fatal to car and driver.

It dosen't hurt to have an EMERGENCY can of ether to use as a last option, even I keep one in my car. Still, you must have a working brain to use it properly as whunter does.

Yeah when my 240D wouldn't start last winter, my father advised me to squirt almost an entire can of ether directly into the hole inside of the air cleaner.

Is that when your oil filler cap hit you in the head? signed the Cantankerous, Dogmatic, Ford Pinto

[Glinko]

No, but it was when I wound up having it towed into town to have the gelled diesel removed from the fuel system. The guy driving the tow truck backed the front end of the car into the side of my garage. Surprisingly enough, the 240 was none worse-for-wear, and the garage took all of the abuse.

I spent my share of time in fields on tractors growing up, and a great many of them have a spot for a can of either built right into the tractor, with a method of injecting it from the cab. It's not immediate diesel death if used correctly.

However a dummy can tear up a rock if given an opertunity..

One must be careful not to use starting fluid or ether on any engine which has a heated intake... that WILL expode. My Ford Diesel tractor is this way and has lots of warning decals on it....
If one disconnects the glow plugs one would have to really work hard to hurt our diesels with normal spraying of starter fluid into the intake tube...

[Wes Bender]

Another consideration in whunter's method is that the one-second worth of ether will be fairly well diluted by the time it reaches the glow plugs. I keep a can around for emergencies, but mostly use it for parts cleaning.

Wolf_walker - regarding rocks, I made a good living at that.....

Cheers,

I watched whunter use ether and he uses it exactly as described.
He didn't mention that he also does not run the glow plugs when he starts them this way. GPs and ether dso not mix.

Propane does a pretty good job, too -- a friend of my brother's was trying to start his 300CD with propane instead of fixing the problems (when I last saw it running , it needed a glow plug relay --- duh). When the propane ignited, it blew the valve cover off. I shudder to think what else is wrong with the engine!

I'd try to talk him out of it, but the body and interior are bad enough I'd rather not tackle it. That 380 SL he has sitting with no engine (especially if I can find the engine and tranny), now, that's another story!

Ether if very unlikely to substitute for glow plugs in a pre-chamber diesel -- they usually WON'T start cold without them, no matter what highly ignitable stuff you spray down the intake. If the mixture is ignitable on it's own, it burns way too early to help start (usually stalls the starter motor), and if you put enough in there to actually get a decent fire, it will burn WAY too hot!

hmmm... what about a mist of gasoline. Maybe this will create a precombustion that helps the diesel to begin cumbusting.

Gasoline vapor has the same problem... it will ignite long before the piston reaches the top of its 22:1 compression stroke, stalling the starter.

[whunter]

Hello coachgeo
"Never", gasoline.

Here is another fools idea you should never try.
I watched a fellow use a torch O2 tank feeding the turbo, the idiot was sure it would be ok, would not listen to advice.
Fastest start that I have ever seen; fastest stop also, the engine topped 9000+ RPM in 90 seconds.
A perfect example of
SNAFU- Situation Normal... All Fouled Up
and
FUBAR- Fouled Up Beyond All Repair

Have a great day.

Did you mean to say he used the O2 or the Acet ?

[whunter]

He clamped the hose set over the center of the turbo intake, with no torch head, locked the throttle at full with a hood prop rod on the accelerator pedal, used a remote starter switch to crank it with the key on and opened the O2 bottle at 500 psi, the main acet regulator was leeking, but I do not know how much.
He cranked it and we heard it scream like a jet engine reving up, we all ran out of the shop.
He was running the fuel off a one quart oil can.
Total engine life was 90 seconds, start to finish.
This is a never do, bad idea.
