today, my son's 240 D ran away. I think it was sucking the engine oil but eventually stalled itself out. I tried vice grips on the fuel line, opening the fuel line to let air into the system, disconnecting the battery, and blocking off the intake. Starving the intake, I thought would do it, but did not shut down the engine, because the previous owner has some mods done on the plumbing and must have been letting in air.

this is a 1985 Euro 240 D with no shutdown lever on the linkage!
If anyone has or can take some digi shots of the vacuum lines above the oil filter, I'd appreciate it if they em them to me or post them here.

This all started when my son said he had low oil pressure the other day. We've come to think that the valve cover is leaking a minimum amount of oil, and he's just not checked it at all since I did his last oil change. So, he was about 2.5 quarts low!!!!. He topped it up, and went out. When he came home, he mentioned that his oil pressure was low. I thought Low-
No oil pressure. What I found out he meant was the pressure gauge was at 2 bar vs the normal 3 bar., and it goes to 3 under accelleration.

thinking that the sender was bad, I proceeded to check that item. It appears that he's got a mechanical gauge. I removed oil filter and put a new filter in, but first put some engine oil in the filter housing. About 2". And some of it went down into the engine or oil lines. I"m guessing that this was the cause of the runaway. We put the filter back together, topped up the crankcase, but actually when we check the dip stick, we were at the top notch. I'm guessing that this full situation helped the engine to start sucking up the crankcase oil.

So, here I am again, asking for help. First, I'd like to know if I can retro fit
some kind of shut down gizmo to kill the engine. Also wondering if a shot of CO2 would harm the lump and would it shut it down? And lastly trying to get a few digi pix of the vaccuum lines coming through the firewall above the oil filter. I've got an octopus there with lots of plugged ends, and on the top of the injection pump is a plastic unit with 2 vaccuum ends which appear to be open.

your turn....
