Post Subject: SR3 Lister engine - diesel spill

I have diesel going into my engine oil, I had the problem some 7 years ago and an engineer said it was the diesel spill pipe, I would like to have a go at fixing it myself, I have the manual but it doesnt explain what to do. Q, Do I remove the top to access the pipes ( where the oil filler caps are) Q, How do identify which pipe is leaking, can I run the engine with the top off? to see what is leaking? Q, If i'm on the right track and there is a leak at a joint do I just "nip" it up (is it an olive) Any help is much appreciated. By the way you helped me with my gearbox cone recently and I have managed to sort that out - thanks Regards Tony

Dear Anthony, First of all remove the three rocker covers and then the cooling air exhaust duct and the thin metal plate thing that attaches the ducts to the engine. This will expose a large side cover fitted to the housing that contains the injection pumps, push-rods and fuel pipes. Clean the whole area up and dry it so any leak will be obvious then run the engine while you locate the leak. It could be a cracked pipe or a loose union or bleed screw. I can not tell you how to deal with a leak because if its an injector pump bleed screw on an non-self bleeding engine you would just do it up again ensuring its soft washer is in good order. If its a self bleeding engine you would need to take more care because you will be tightening a banjo union with two soft washers and the possibility of twisting the banjo and causing another leak. If its the leak off pipe on an injector then it could either be an adaptor screwed into the injector that has come loose or the olive type union that fixes the pipe to the adaptor (it may be a banjo union here.). It is also possible that the main fuel supply to the injector pumps is leaking. This time its more often a union than a split pipe. My advice would be to remove the whole leak off pipe system, use a blow lamp top heat it all to red hot (hoping no-one has repaired it with soft solder) and letting it cool. Then wash out with great care. This will anneal the copper and make it soft again so it is less likely to split in the future. If its a split pipe or pipe joint it will need brazing or silver soldering. Tony Brooks

I have just re-read my reply.I noticed I forgot to tell you to remove that side cover and I meant clean the stuff you find inside it. Cheers & the best of luck TB
