if used correctly in a emrgency situation it can be used , to start it every day , not a god idea , it is very possible to get to much in the engine and bend a connecting rod , blow a headgasket , ive even had them come in with the turbo cracked and intake blowm completely off the truck , so it isnt good to use , the biggest problem is it isnt used correctly

yeh if hes having hard starts, have him swap for a new glowplug relay, or check the relay to see if he has voltage. if its good there then pull the glowplugs indiidually and check them.

but if he has to do that for a while, then unplug the glowplug relay (if its bad already then dont bother)

thanks for the reply. so by using it correctly, i take it you mean as little of a spray as possible?

when i use it , and have to from time to time ,i use 2 people, , the person inside i tell them to go ahead and try to start , after the engine is already spinning so its not as hard on it , i dont spray it directly in the air box , i hold it back and slightly mist it in ,doesnt take much, its really best to diagnose and fix the problem, lot less to repair problem, than replace engine

testing the glow plug system yes would be a good place to start , to remove the glow plugs to test them woud be overkill, they can be tested very easily by just unhooking the harness right outside the valve cover , and test them there , 97 models were bad for relays and the gow plugs themselves , so just a few minutes of diag would tell the tale

I gotta ask, where did you hear starting fluid (ether) is bad for diesel engines? It's made for diesel engines.

As Scuffy pointed out when used improperly it can do damage, But I took your question as what is bad about ether being used to start a diesel engine itself right? The truthful answer is if you buy quality brands, nothing. If there was something inherently wrong with using ether then Caterpillar wouldn't be putting automatic ether injection systems in their engines built for the North American market would they?

Some will say it hurts the cylendars, how? The name brands all have additives for upper cylendar lube, besides, the injectors are spraying fuel also (unless they aren't and that's why it won't start in the first place) .

Now I've seen heads practically ripped off of blocks with the bolts stretched almost a quarter inch from ether, but it wasn't the ether's fault , it was the guy who sprayed a half a can into the intake's fault.

So, next time you see someone post on here that "ether is bad" and nothing else,(always reminds me of Mr Mackey from South Park) ask them why it's bad.

Here's the proper way to say it " ether is bad in the hands of the unschooled"
and they should read Scuffy's way, hard to hurt an engine that way.

thanks for the input MarlandS. i have no clue either way if it was bad for them or not. i just told my freind that i had heard it was bad for them, and he asked me why? and i told him i was unsure of the effects it does to the engine so i figured i would get other opinions about it on here. and you say name brands are ok for them? can you give me an example of a name brand? he is using a can called THRUST starting fluid. thanks again. anybody else have an opinion on this subject?

Only if used right and should NOT be used on Newer Engines.
The "Diesels" you are referring to are NOT PSD's.

Don’t use ether (starting fluid) to start a diesel engine. Ether has too high a flash point and when put up on glow plugs can blow the valve cover right off the engine.

You run a risk of hurting something EVERY time you use starting fluid on the engine.

And you ARE doing damage to it EVERY time :thumb:

Not on newer engines... just passenger vehicle or any newer diesel engine?
The "Diesels" you are referring to are NOT PSD's.
And PSD's are different than any other electronically controlled diesel engine?

Don’t use ether (starting fluid) to start a diesel engine. Ether has too high a flash point and when put up on glow plugs can blow the valve cover right off the engine.
While I did neglect to caution about glowplugs, that's a situation where knowledge of the system, the right way to do it comes into play. How hard is it to disable them or wait about 15 minutes after the key is cycled to "on" then not cycle it back to "off" ?

You run a risk of hurting something EVERY time you use starting fluid on the engine.
And since no one is going to stop people from using ether, why not broadcast the proper way to use it on PSD's instead of spreading fear? I've been using ether when needed for over 30 years on everthing from mechanically controlled engines to hot plated engines to PSD's without one incident of damage that could be traced to ether use.

And you ARE doing damage to it EVERY time :thumb:
That's definately debatable but blanket statements usually are. :wink[3]:

MarlandS,

It sounds like you have been around then, and you should KNOW how easy it is to get the MEASUREMENT of the starting fuild correct right? :dunno:

If they are already having a problem starting it, then how would they know how to disable the glowplug system? :dunno:

Diesel ignites around a compression of 14:1 up to 22:1, Gas is around 10.5:1 to 11:1 BUT Ether(starting fuild) on the other hand IGNITES around 3.2:1...which means it will ignite before the piston reaches the top of the stroke trying to drive the motor backwards, creating a HUGE explosion.

Also, Ether ignites around 350 degrees, how hot do you think the glow plug gets also?

Further more, Ford and International does not recommend the use of that starting fuild in the motor.

Glow Plugs is part of the problem but so is the compression ratio needed to ignite the starting fuild is another one;)

Blanket Statement or NOT, it is NEVER a good idea to use Starting Fuild :thumb:

Starting Fluid

Pay attention to warnings above. I have seen first hand pistons that have fractured from starting fluid use and I have heard the war stories about blowing off intake manifolds.

I have used starting fluid on rare occation to start the hard to start monster.

Never spray direct into the air intake. Something will break for sure.

Understand if you use it you are playing with fire and may break parts.

Reduce the risk by fogging under the hood while someone else turns the engine over.
There is enough boost in fogging under the hood to get one to start. This also reduces the chance of one piston catching a huge boost of fluid and blowing that piston apart.
As it fires up and you hear that hard rattle in the engine from the starting fluid detonating against your pistons remind yourself to fix the problem, it is cheaper than replacing the engine.

If you have not tried it WD 40 works as a better Diesel starting fluid, not quite as explosive but still fires better than diesel fuel for cold starts or after running out of gas and needing to prime the pump.

On my 2002 it says right on the airbox, do not use ether or any other starting aid....And that advice should be heeded, unless the glow plug relay is disconnected...Its not worth the consequences.
