every time i turn my 300D off i cringe .. this is my first diesel and i dont want her to run away if she does ill rip that u tube off and put a piece of plywood in the way..


when i went to buy the car the owner said. it ran away once because the vacuum pump failed.. i groaned.. wonderful just wonderful but it appears work was done to it and a new vacuum pump dont know if new style or old but is new out of box.. starts and shuts off fine ill have to check my dipstick color and get back with ya


as long as i put the correct amount of oil in i should be fine right?

They can still run away if the turbo bearing seals let go and start feeding oil into the engine through the intake. A maintained/cared for turbo/engine will not likely have this happen, usually it starts burning oil long before it becomes "critical" that they could let go and cause something like that......

mplafleur,

What kind of shape is the body in on your 240D, and is it a stick or auto car? Just curious.

If you are honestly scared of runaway...just carry a good sized fire extinguisher.

It has more than one use too...you never know when you might need it

If mine was running away, I would pull the CCV vent and check for oil then start cracking IP lines with a wrench (I almost always have my wrench on hand after doing work on the car).

One of his friends has it, awaiting the installation of another engine, which he has.
I have been asked to R&R the engine, but that will be after the holidays.

I carry a fire extinguisher in my trunk courtesy of your thread on runaways.

The fire extinguisher is the dust, not the foam. I have no qualms about injecting it into the intake in case of that scary day.

The dust type will quickly destroy your engine, you'd be no better off letting the engine runaway.

A CO2 extinguisher is needed to stop an engine.

Hello,
My dad has a 240D too, its a W115 chassis "75" and I'm just curious here what causes an engine to "run away" its the first time I ever heard that term, the link "whunter" had posted died, and why cant the engine be rebuilt or fixed "you can always fix anything up if you have the parts and tools" is the engine so damaged that you cant fix it and if so why not, can having toomuch oil in the injector pump cause this too, I dont think so but could it ?
Thanks, Jeremy Brett

I repaired the link.
Here it is again.

Run away diesel, why does it happen?

I had a 79 Peugeot 504D with a 4 spd manual transmission many years ago where I expereinced a runnaway while driving. I was in second gear and all of a sudden it went full throttle and the car took off. I shut the key off but it kept accelerating. Scared the ***** out of me. I left it in gear and applied the brakes to slow down and stopped and was able to stall the engine. Car was towed to the dealer and I was told the IP main shaft seal leaked diesel into the crankcase till it got high enough and fuel was sucked through the rings and caused the run away. Had the seal replaced and all was well- no harm done to the engine. If it was an automatic the engine woulda been toast.

Since it was a stick and I kept good brakes on it, I would just leave it in top gear and stand on the brakes. That would slow the engine down enough that it would return to normal. Seems to me a dirty airfilter helped cause the problem. VW later came out with a plastic cover that went between the cam towers and the valve cover that helped beat the problem. Kept the more liquid sort of oil from the intake side. My understanding for big diesel mechanics is that they keep a board on hand to block the air intake on runaways, much like Diesel Power said. Only problem is that it's likely to cause the engine to draw in all its seals. Shame you can't get a doner engine from a salvage yard. You put enough work into the car, I hate to see it go.
Oh, and BTW, since I'm about to buy an '86 300SDL (with 220k miles), What pray tell caused the rod-thru-block on yours? I'd really like to avoid that.
Thanks.

I think this was a common fault with early vw diesels. There was a factory approved modification to stop it happening. It is ancient history to me now so I am not sure of what it was. I never owned one of their diesels of that vintage.

My limted memory in this area is it was other than just adding a shield. Yet this may have been either an earlier or later modification as well. There were hundreds if not thousands of owners that stood beside their cars while they just reved to death.

This is how Detroit Diesels used to run away. There was a situation where engine oil would be introduced into the intake tract and covering the air intake was the only way to kill it.

In this particular case, loosening injector lines would probably not have killed it.

'85 190D 2.2 auto with runaway at 75 mph due to oil overfill. I was able to slow the engine down by braking. TC must lock out at higher speed?
