Omega General Help / Re: Dangerous full throttle incident, any ideas please

« on: 03 January 2009, 19:03:08 »

Thanks for your help guys I will be working on it Sunday - compression test then run without turbo feed connected to the inlet manifold. (if it runs)! If it runs I will follow up the crakcase vent (look for excess oil mist), does anyone know how easy it is to remove the cam cover - it does not look straightforward? I have not topped up the oil as it does not use oil normaly however I do park it on a very steep (40deg) drive each night

the Ruston paxman made by GEC in Newton - Le - Willows Merseyside

Anyway back to the problem in hand, I have stripped the air side of the turbo & its full of oil so I think the theory about the engine over reving through buring the engine oil is correct? the sump has not run dry & I have run the car without the turbo air feed connected to the inlet manifold oil light all else OK! I am not convinced the turbo is at fault as there is a lot of oil up stream of the turbo possibly from the crank case ventilator? Anyone have any thoughts? Any volunteer test pilots? the wife has already refused & I cant find a sane reason to couple up the turbo & try again!
thanks for your support chris Mac

By the way I used to make those Ruston tinkers (diesels) when I was an apprentice before they went bust!  Mac

I am going with the turbo having blown its oil seal & feeding the engine theory! I will disconnect the inlet hose to the engine & check for heavy oil deposits, then possibly try to start it with the turbo disconnected to see if it sprays misty oil everywhere / revs through the roof? Wish me luck! - anyone got a spare turbo?

thanks for your help Mac

Dangerous Omega! Hi I have just experienced a dangerous full throttle incident on my 03 2.2DTI and could do with some advice please? The car suddenly took off like a banshee in 4th gear (no throttle applied)! switching off the car on the key had no effect. I had to stall the car to get it to stop which frghtened the hell out of me.Luckily I had a clear road & no roundabout ahead. I stoppd in a cloud of  grey smoke, the engine re started on the key but ran away again straight through the rev limiter again only stopping with a forced stall
       Can anyone assist with potential causes? being drive by wire I thought this would be impossible?
thanks  Chris Mac
