Emergency Stop for carastrophic runaway
I've been cleaning and fixing and replacing things in my car as I learn what goes where and whats missing and what needs rehab......Amongst my pondering I have been reading and reading.....and reading the archives....
The normally dark light bulb above my head emit a faint glow last night As I pondered the turbo inlet and the soon to be installed shut off valve at the injection pump.... Just shy of having nightmares I'm slowly and methodically preparing for the shut off valve replacement in hopes of not gaining personal experience with a runaway condition. OK OK enough rambling here's my idea...... Instead of a phone book (No phone in my garage) I'm going to have a hockey puck handy.....If I get fancy I may take a puck and (with a circle cutter) cut a circular groove the same diam. as the turbo inlet. whaddaya think?

you're better off having wrenches handy to loosen the injector lines. I was a bit paranoid about the runaway issue, so here's what I did: I set several vise grips on the nuts leading into the injectors. The nuts were "almost" fully tightened, just enough to seal, but not fully tight to securely stay that way for long. The vise grips were attached, similarly pointing 1/2 way back. This way I could rotate several nuts CCW in just a second if I needed to. All you need is to loosen them a little, because the injector will not open without over 100 bar of pressure.

Get a CO2 fire extinguisher and hang it next to the garage door. If your engine runs wild give it a shot of CO2 into the air intake and it will stop right away with no damage.
You will have protection from fire too. The reason for hanging it near the door is you never want the fire between you and the exit. If there is a little fire and you are trying to put it out you want the door at your back just in case it doesn't stay little. |

...and make damned sure it is a CO2 extinguisher. The other chemical extinguishers would make you wish you had just let it blow up on its own.

Don't mess around with a hockey puck. Get an old phone book, wooden board, fire extinguisher. When your engine runs wild and is roaring and vibrating away you won't be able to choke it with a hockey puck with a little groove in it, near as well as the above items.

In a pinch, cut or pull off the fuel line between the lift pump and the injector pump. Perhaps even squeeze it shut with a vice grip.

With the air cleaner off a piece of 1x4 or 1x6 will choke it out. I wouldn't even think of putting my hand near the intake on a runaway engine!

I wouldn't put my hand over the intake of a runaway engine to try to choke it out-that's what I meant.

he shrunk himself down to 1" tall, then ran between the blades so fast it was as if he was standing still. They have a video of him shrinking down real fast, it's really cool, especially the variable sized tailor adjusting his clothes within just a few milliseconds!
