I'm truely thinking about it. Right now, I will probably look into rebuilding it and see what that will take. A new 300 drop in (used) is an option too. Or maybe just LS1 it and race the piss out of it and sell the racecar. Who knows. I have too many toys and the expense is killing me.

I'm thinking another emergency kill option could be to mount a halon extinguisher in the engine compartment with a pull cable trigger, and plumbed into the intake. I think if you were to flood the intake with halon, that would kill the combustion in seconds, but it's just a theory. You could possibly have a T valve midstream from the halon extinguisher, that would allow you to direct either in the intake for run away conditions, or alternatively into the engine compartment for fire suppressant.

That's crazy! I've never heard of that sort of thing. Excuse my ignorance, but is the rollover part of the equation?

has this happened under normal use- driving or hills?

I am really interested in what you decide as a replacement.

no its not normal. The Rover 2.5td had a reputation for a few of the engines doing this. In order for a diesel to run on its own engine oil the engine has to be in pretty bad shape. In Daves case he had inverted the engine.

Yeah, I agree. Except I have been over in that engine somewhere around 15 or even more times. So I don't understand why this time. I think there was something else wrong before it happened. It has been losing power and gaining heat for a year or so now.

You are correct, and actually I am going the Halon route as well.

You guys are just killing the desire for a diesel in me.

Genuinely sorry to hear about this incident Buck. Based on previous threads where you have wanted to eke out more power from your motor I'd say a V8 might be a good choice at this point.

Maybe, but I am leary of that. The 300 has more useable power for what I do. A 4.6 maybe but then it's money again. I really don't know what to do. Were pulling the head and pan and taking a look.

Edit: It's important to note that I had this engine for 8 years. When I got it, it had 50k on it. I have raced KOH where it hit 1450 egt's. I have rolled it around 15 times. All I ever replaced was a fan belt, alternator, and oil changes. I can't really be that bummed, even though I am, since I have no money right now. But the engine is a good engine. Not perfect, but very fun.

Maybe if you would drive harder you could get over the obsticles instead of rolling down them. Then this wouldnt be an issue!

Halon has not been produced in years, so unless you have a secret stash it will be near imposable to obtain.
http://www.periphman.com/fire/halon-...hers.shtml#qA1
The valve type shut off works well, I have seen it in use and is very effective! but if you want an extinguisher co2 would be available. co2 can also be used to run air tools and inflate tires too, making it even more attractive for some!!

Fit one of the fire suppression gas systems to the intake, then you can stop it by flooding the intake with non-flamable gas. The only variable to work out is how long it needs to spray to avoid re-starting.

I have a friend who had a very large twin diesel yacht. Once when coming back into the dock, he could not shut off the fuel, so they just sat there idling. The engine manufacturer told him to take a wet towel and throw it over the intake/air cleaners. This might also work if you can get through the smoke to the intake -- just jam a wet towel in the port.

may be this is the good time and right thread to find out the best preventive solution for all us Tdi owners. So far i thought Td5 were more prone to this.

Thanks. But, I am being positive about it. You can't wheel like that every time and expect and engine to live forever.

I think the idea crown posted is the best. I wouldn't want to spray crap into the engine and opening the hood to throw something on the air filter is never going to happen. I thought my rig was going to time travel.

I am going to look into the mechanism and see if I can make one that will fit these engines. It is a smart thing to have.

Would fitting a dry sump fix this? It would keep oil pressure even if inverted in theory.

there is more then one way to have a run away diesel engine. turbo seals, being inverted, excessive blow by or any less common way of introducing fuel to the engine. co2 would not harm the engine for the purpose of shutting it down in an emergency. but the mechanical flap at the intake would prob be the best, easiest, resettable and most reliable set up. they are used extensively in the oil patch for a reason, they work, they can be tested and are relatively simple.

Just get one from a VW TDI. People commonly remove them and throw them out, so getting a free one should be simple.... They are vacuum controlled. They call them the "anti-shutter" valve.
