Hi Folks.. I"ve been working on my 580C for some time now to deal with raw fuel smell from exhaust...this winter I suddenly loss power and eventually ended up tearing apart my injector pump after some research here... turned out that I was also a victim of the "flex-ring" disintegration that spread a major pile of fine black particles throughout the inside of pump...I replaced this ring and reassembled pump/reinstalled back in my D-207 engine...for those thinking of redoing their injection pump, it wasn"t as scary as it"s made out to be by some; just mark where things go including timing and take pictures; I highly suspect a pro can rebuild a pump in less than an hour...anyways, the pump ran fine but the stench of raw fuel was powerful...in fact, I noticed oil was blowing out my crankcase ventilation hose onto ground after running it a bit... then I discovered engine oil level was at top of dipstick (that"s why it was blowing out) and very thin/diesel smell...I actually drained about 14 quarts when it should have been 7 quarts... so I know it"s diesel fuel despite mention of power steering fluid which I removed steering pump and replaced shaft seal needlessly...and yes, I tried replacing the injector pump drive shaft seal previously which didn"t seem to help at all... and I read about torque converter and hydraulic pump...not them I"m sure thanks....so what I am thinking is that the pump flex-ring obvious started to break down over time... the fine particles I assume would move into injectors and perhaps this is causing heavy fuel dripping through cylinders into oil pan...and subsequently giving me the strong raw fuel smell from exhaust that has worsened over time... something is forcing a lot of fuel into oil pan over a very short period of time now... thanks for your review and comments...
