will_warne Posted September 28, 2007 Share Posted September 28, 2007 tracked to a leaking injectorbut like a phoenix(not this one) it has been rebored and rebuilt ready to go again That's a bit of a mess, Tony! How much have you had to bore out on the engine? Quote Link to comment Share on other sites More sharing options...
Exmoor Beast Posted September 28, 2007 Share Posted September 28, 2007 That'll hold a fair bit of paper down! I don't know much about engines but I'd wager it shouldn't look like a dogs chewed it round the edges and have a gert hole through the middle. Have you upped the CC in the rebuild Tony?

sheeppimp Posted September 28, 2007 Share Posted September 28, 2007 PAH - I can match that! Les. if we're gonna play that game: from my old 110 NAD still running with this (a bit rattley admittedly) Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted September 28, 2007 Share Posted September 28, 2007 I had one just like SheepPimp's - ran fine, no loss of power, just a HORRIFIC rattling from its innards. 4 new pistons and it went back together fine too... Tony - what was the injector fault - hosing, poor spray pattern etc? Could this be due to your veg oil system do you think? I'd be interested to see some really close-up photos of the injector tip if you can do something clever with a magnifying glass. Quote Link to comment Share on other sites More sharing options...
white90 Posted September 28, 2007 Author Share Posted September 28, 2007 John apparently it was dribbling fuel rather than spraying it the injector has been rebuilt with a new pintle. don't think it was veg system linked (but could be) only one injector was problematic when tested and the rest of the engine looked fine. I wasn't risking i so I removed the entire system and now am back on dino Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted September 28, 2007 Share Posted September 28, 2007 It can be a problem with biofuel, since you get buildups in the injector nozzles which stop it sealing properly, so it dribbles before/after injection, and this can cause holes in pistons when it's shot its load before it should even have started to spray. That said, it could just be dirt, manufacturing or material fault, phase of the moon or bad luck... Thanks for the photos though. Quote Link to comment Share on other sites More sharing options...
ciderman Posted September 28, 2007 Share Posted September 28, 2007 Looks as if the dribbling injector caused a major case of bore wash , Nice ashtray BTW Quote Link to comment Share on other sites More sharing options...

ciderman Posted September 28, 2007 Share Posted September 28, 2007 Is bore washing not a petrol thing?Chris Abolutely not , Leaking diesel injectors will wash the oil from the bore just as in the petrol engine, causing major friction issues then metdown.

GBMUD Posted September 29, 2007 Share Posted September 29, 2007 D'OH, of course. Not sure I was thinking straight when I posted that. I guess that the dribbling injector/bore washing would explain the rising oil level... Chris Quote Link to comment Share on other sites More sharing options...
