I have a 4 piston Diesel engine on my generator, I have a nasty oil sludge continue to build up every time, I have flushed the engine with engine flush liqui-moly probably six times, but after it is clean the sludge builds up again in couple of days, I got sick and tired of going down there and get all messed up with nasty oil.The engine produces while smoke continuously, not much but visible enough. I get oil coming onto the air filter, the place smells nasty because of this. The light bulbs flicker when running on the generator, it heats up fast and shuts off when I put load on it as an AC. Can someone please help me out and let me know what to do?
Get a new one or get that one rebuilt.
I forgot to mention that, the coolant level is stable, I have changed it already and all is fine is that area. I have done today a cleaning job, I mixed 3 liters of fresh engine oil with 2 liters of diesel, and poured it into the engine, ran it for 5 minutes and drained it, repeated that 3 times with fresh oil and diesel every time, I got loads of crab coming out till I finally got semi-pure liquid, then poured 5 liters of fresh oil with new oil filter, and then ran the generator and put load on it, no major change apart from no more flickering lights, white smoke still coming out and can not say if it less than before. If this does not hold water, I am going to take it to the shop. That is that.
The sludge is an indication of coolant leaking into the oil, as is the white smoke and the fact its over heating, This is due to either a cracked water jacket or sleeve or cylinder head and or gasket, As to what to do? Have it properly diagnosed by a qualified mechanic and if need be rebuild the engine or replace it. As replacing the cylinder sleeves at a reputable shop can cost as much as a new engine.
