You can get a lot of comments on using ether in a diesel engine both pros and cons.
Some things to consider:Using ether in an engine with glow plugs can be like playing Russian roulette. It may work a few times, but it only takes one bad event to turn an engine and / or ancillary parts into scrap metal.
-----Blowing the head gasket, blowing a chamber out of the head, bending a rod, cracking a piston, backfiring into the intake, exploding the intercooler (CAC) and fire can be some of the results of the use of ether.
Ether use also removes the lubricating qualities of oil on the cylinders so the rings wear harder on the walls.
Some recommend using WD40 since it has some lubricating properties and is a light lubricating fluid with some aromatics in it so less damaging but still for the long haul fix whatever is ailing the starting system and do not use any starting fluid of any kind.
Personally, I would not spray any combustible into a diesel engines intake system.
You may get away with it on gassers, but even on gassers I have seen it blow air filters apart.
Can be very dangerous stuff, so if you use it, please be extra very careful!
