Its funny but most of the time I am inspected for a PAS for field compression more than Petrochemical Plants in the Cities.

I am surprised this isn't an issue down there for the amount of flack I get.

 

Hey lil dog, do you have any pics of your motor?

 

I drive the rolling bomb (gas cylinder truck loaded with oxy, acetylene, propane, etc.) into refineries several times a month. Never been asked about an air shutoff. I catch more crap about my beard.

 

About a month ago, a cummins 8.3 ran away on us. After blocking the air filter inlet, the engine proceeded to suck the intake piping and air filter into the turbo, which it did quite effectively. After seeing that, I know I'm not going to put any body parts in front of a tacked out turbo diesel

 

Trying to find info today, I came across a story in the Houston Chronicle. It said in that in the explosion at BP that killed several people that the vapors got to a truck. The driver tried to kill it and of course it wouldnt. When some of the men around heard this, they began to run. That little bit of warning saved some of them. I still cant find any petrochem plants in Texas that requires this device.


Wannadiesel -Up untill about 10 years ago we could have beards. Now we have to be clean shaven and decked out in Nomex all the time.

 

I emailed Roda Deaco directly. www.rodadeaco.com

They responded within 24 hours, make sure you give them your application and they'll direct you to a good us distributor.

Your 98 a 12v right ? I have talked to several people about the wonderful 53 block. knock on wood no problems.

 

I always carry a CO2. They won't fry your engine. I've seen them used to stop runaway without damage. oil burners need oxygen, fuel and compression. lose any one of the three and all you have is a neat stinky paperweight. blowing a full CO2 into the front right headlight (at least for my stock 99) will flood out the intake with non combustion supporting gas. I wouldn't stick it to close to the turbo thogh, the thermal shock of dry ice on hot compression vanes couldn't be good.

 

I did something similarly stupid last winter.

At about 5degrees, the truck wouldn't start, so I put a shot of ether in the air intake. It still didn't start, so I tried again. The issue when it finally started was that I had no evaporation (cold), ether buildup in the intake system, and now a huge vaccuum pulling the rest of the ether into the engine.

The engine held together, but revved to the moon. The turbo bearings roached from overspeed and no lubrication (cold start).

My luck held again when the compressor wheel held together and no parts enterd the intake.

Years of busses, generators, trains, and equipment experience somehow meant that the warning sticker didn't apply to me...

 

I am very suprised that the ether didn't light as it went past the grid heater.

 

WOW! Thats one of those time when you wonder why you do some things.

 

Not sure about inland, I've spent most of my time offshore. I know that in the Gulf it is a goverment regulation. Not sure from Coast Guard or MMS. Probably find the requirements in API RP14C or RP 2D, I know every diesel engine offshore has to fitted with one. Also they must be tested monthly. Most detroits used a manual flapper. Lot's of our Cat's etc use a electronic controlled flapper. Some use an automatic type that I think is called a Chalwin valve or something like that. On our detroits we would test them at idle to see if they worked. If you do it at full speed you can suck the seals out of the blowers. Not a problem in an emergency, but something that you don't want to have to fix monthly. In an overspeed situation, it won't always kill the engine but it will dog it down enough to take care of the main problem.

 

I think they're more concerned about turbo bearings letting loose and spilling oil into the intake, rather than fumes from something else. And I imagine they want it out the back in case of a crash or some circumstance where the driver is disabled. Just like the battery shutoff in the gasser drag cars.

NEVER put ether in the intake, and disable the grid heaters, they WILL ignite the ether eventually. If you spray it directly in the air cleaner it will build up, just like you found out, and cause a surge or a runaway.
I use ether in the winter plenty , my truck won't start if it's not plugged in if it's frigid out. My heaters don't work and I keep it plugged in when I'm home, but sometimes if I'm not I have no other choice. It's a pain to take off the intake tube at the horn all the time, but I've seen the heaters light it on fire and the buildup in the tubes/intercooler all go next, it's not pretty. And I had a buddy that sprayed into the air cleaner on his old chevy and it actually caught the air cleaner on fire and created a near runaway.

I haven't gotten a chance to install a guilotine(spelling) shutoff in the air tube but I plan too as soon as I can. No electronics either, I like the idea of it being mechanical. (ever seen Apollo 13? lol I don't trust electronics) even at $600+ it's cheap insurance when a new motor can cost $5000+, not to mention the danger to you or others if the block splits and lets one of those huge rods out.

 

OK, I finally got some pictures uploaded to my gallery of the install.. Pretty simple really.

It is mounted right up tight to the intake horn so there is less likely a chance for a pipe to collapse or suck through..

 

An Award???? Im glad they didnt give the driver one, that would be the first thing that anyone would try is turning the key off.

I bet the BD felt like a moron when a Jr. high student showed how it was done
