It's mid to upper 50s. All new pistons and liners .. Maybe a bad valve? It doesn't blow any smoke going down the road that I can see. But after idling for 10 min then take off it will blow big puff of blue smoke. Fuel is right on the mark even after 3000 miles but seems a bit runny and diesel smell?? Good thing is there is no sparks coming out of the exhaust yet!!!  | ||

Take a paper towel and drop some oil from the dip stick if it runs it is diesel in the oil if it puddles no diesel in the oil good luck | ||

Cory - How many hours/miles on the new pistons/liners? Sometimes it takes a lot of miles under load for the rings to seat properly. Idling in cold weather isn't the best for the engine, especially low idle. Better to fire it up, kick on the fast idle until the air pressure pops off @ 120 psi, then put it in gear and GO! You ARE using straight 40wt oil, aren't you? FWIW & HTH. . . | ||

It sounds like you may have a broken oil ring. Not a big problem, and it happens. bummer. Run it like you stole it, or at least borrowed it from an ex girlfriend's new boyfriend. If you use Clifford's test, you shouldn't see any bleed on the paper towel. If you do, you'll have a bigger problem. | ||

Dal said "If you use Clifford's test, you shouldn't see any bleed on the paper towel." Yeah - you shouldn't see a "bullseye" with a dark spot in the middle and a lighter ring around the outside. | ||

Smoke Colors: White smoke is unburned diesel fuel, Blue smoke is oil, black smoke is incomplete combustion of diesel fuel | ||

Sarcasm set to high... Why don't we list off every freakin' disaster that he doesn't have, just for fun, and scare the crap out of a busnut that's in a foreign country, far from home? Sarcasm turned off. Hello Cory! The blue smoke after idling, with a 30 wt oil in the engine, that clears up right away, once you load the engine, isn't worrying me right away. I expect that the air box is loading up with a bit of oil, perhaps, and quite likely, only due to the thinner 30wt oil sneaking past the blower seals or the oil rings. Fuel in the oil worries me, but only if you don't find out for sure. Fuel will thin out the oil (and trigger loading the airbox...) And diluted oil doesn't protect the bearings very well. You note there has been no oil consumption in 3000 miles, how much did it consume before? Or has it always stayed full? Another tell tale that fuel might be leaking into the oil is the appearance that oil use has gone down. The fuel being added to the engine might be keeping the level on the dipstick up. Fuel in the oil can easily come from a weeping injector, all those connections of the fuel supply and return tubes under the valve covers weeping, in extreme cases, a cracked tube due to being overtightened on install. A handy busnut can simply pull the valve covers and watch for the little rivers of clean fuel tracking in the dirty oil down from each injector or the loose/cracked connection. But, before fooling with tools, I'd do the paper towel test, which will show a big dilution, and pull an oil sample and find a truck dealership or lab local to where you are with the testing machine, so you get results quick. If there is fuel, you may still have choices for getting home, with a minimum of worry or expense, depending on the rate of fuel leak. If it is light, change the oil more frequently and continue the adventure. As for your choice of 30wt for the winter, unless you have no way to heat the engine, and have to start it in temps down near 0 degrees Farenheit, just put 40 wt into it and again, no worries. That snow covered coach up there to the left has 40wt in it year 'round, and starts immediately with either the Webasto, or the electric block heater with the temps below 0 degrees. happy coaching! buswarrior (Message edited by buswarrior on November 14, 2011) | ||

I am starting to think it could be the 30wt oil getting past the rings being that this motor has under 30,000 miles. They are all new fuel injectors along with all new fuel tubes. I try to find somewhere to get the oil changed. Not having a easy time up here in Quebec City Quebec | ||

Cory - Try the paper towel test again, not sure what you meant by "it spread out with a dark spot in the middle." When you drop the oil on the towel, do you end up with an outer ring that spread really quickly and is a different shade than the inner ring? Or was the spread more even with approximately the same coloration except for the center being slightly darker? After the visual test, try the "sniff" test: Do you get a strong smell of diesel on the towel? If the answer is yes to the first pattern and/or the sniff test, you're getting diesel in the oil somewhere. If you get the even pattern and no smell of diesel, drive it until your next scheduled oil change, then fill with straight 40wt. Oh, and if you need to top it off prior to the oil change, adding straight 40wt won't hurt. As for obtaining the oil, look for a local petroleum distributor and/or use the "dealer locator" from the manufacturer's website (Chevron, Shell, Exxon, etc.) FWIW & HTH. . . | ||

Say what you want but I use whatever oil I can get and have 70-80,000 mile on my coach and the majority are with Delo 100 30 wt. Maybe 25% 40 weight (Rotella and Chevron) from Alaska to Arizona to Minnesota to Florida and I have had no troubles. I worked 15 years for a Chevron jobber.I do not believe your oil is your problem. I KNOW of documented instances where 0w30 syn has been used in diesels in the Arctic and the desert middle east with no serious ill effect. Detroits use oil. Yours is not. I would drip a spoon full into a shot glass and freeze it...if it remains runny it's diluted. the bullseye test should tell you what you need to know...can you post a picture? | ||

I buy my oil from Traction truck part stores, there are two in the Quebec City area. First is just off 540, the second is on Hyw 20 on the other side of the river. They may help with a quick oil analysis too, although I have never asked about that. My store delivers locally, and they carry Rotella. My store usually has to order it and I go pick it up the next day. Traction Québec 3220, av.

Agreed, Clifford. For many years DD recommended 30 wt. for normal running, 20 wt. below 40°F. I still run 30 wt. when I can't find 40 wt. My engine is an old 2-valve and hasn't used more than a gallon of oil in the last 68-70 K miles. As close as I can figure from the hub and the logs I have, the engine has close to 394,000 miles on it since an inframe major was done. It still held 55 psi on the mechanical gauge before I changed the rod and main bearings and did a head o-ring job on it. Now it holds 60 psi at anything above 800 rpm. If he's not leaking oil through the blower, and there isn't evidence of fuel in the oil, I would still suspect an oil ring. The happy thing is that the engine will still run for another bunch of miles. It doesn't take much oil past the oil rings to make a smoke cloud after idle. It will also take a few minutes for it to clear up once you start moving. | ||

It does not HAVE to be broken....it could just be stuck...which is not uncommon...specially if you have used multi-weight or cheep single weight. MAYBE a little diesel in the oil would help here. PS. don't try this at home | ||

For help, you can try Dupont. They used to be the go to place for commercial coach service, very friendly and quick. They used to run a fleet, and with the de-regulation in Quebec, they sold the fleet and decided to just focus on bus refurbishment and heavy re-builds. As you have probably found out in La Belle Province, it may take a minute or two to get someone on the phone who speaks english. Their shop used to be a fascinating place, buses all over the place in various stages of torn apart and rebuild, as well they build those diesel powered trolleys for sight seeing.

Thanks I am in Windsor Ontario this week. Smoke is still there not getting any worse or any better at this point. I have a new problem Left rear height control valve not working. Trying to find a new valve but having problem finding the right one. All I have is the MCI part number and they are having problems cross refrencing it 12c-6-2 |
