Ruston fekker

And the same to you!

What the heck is one of those?  Google don't help me..

Not quite the same, but close enough.  We used them as Alternator sets whilst other applications had them as main propulsion sets ( as the image link) or electrohydraulic propulsion in main line train engines.  No doubt Martin Imber or Lizzie Zoom will elucidate....

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

First off, no experience of these Omega type diesels.

Any way to short the air supply and bypass the turbo and fool it into running?  Might give room for thought, given the radical path this thread has taken....

That is a modern descendant of the 1930's English Electric 10" bore 12" stroke lump

Started as a straight 6 250bhp and a late V20 with 280mm bore over 9000bhp

Most powerful per cylinder in UK rail traction was a 2400bhp straight 6 downrated to 1800bhp and 280mm bore (6RK280 I think)

Which lumps?

EE?
Paxman?
Napier?

well, if ever i needed a reason not to buy a diesel, which i dont, it would be...?

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

I can lend you a pair of axle stands!

turbo oil seal,being a dt it will run on its own oil untill the sump is empty then the ends will give up!!

it may be turbo oil seals ,but you need to carry out a compression test to elimate piston rings ect , and fully check the breather system for blockages  ricky

[stuyg]

deffo turbo get it all the time on mercs, if you do try other options be prepared to stall stop it very quick or you will shoot the bottom end  

[Kevin Wood]

If the oil is well upstream of the turbo it points to a breather or something, as you say. Can you remove the intake ducting and ascertain where the oil was entering? i.e where do the oil traces start?

Might be worth disconnecting the breathers and giving it a run. See if you get excessive blowby gases from the open breathers.

hi.have you changed or topped up the oil,if over filled can cause the problem you had(hands up on my part done this with a renault diesel a few years ago).
