Hey all,
I’ve been having this issue lately, my truck is drinking oil at an ridiculous pace. At least a gallon every week. Not leaking as much but it’s going somewhere else for sure. Attached is a video of the idle smoke while cold. It doesn’t smoke as bad during the day after it’s warm. Makes me think rings. Opinions?
I will check fuel filter for sure when I get back. Last time I checked it was good. I guess the smoke does have a slight blue tint to it. I’m just worried it’s rings!
I think if the rings were bad enough to burn a gallon of oil weekly there would be some significant blow-by too.
I will check tomorrow after driving it to work. It is a used turbo from another 7.3. It starts up fine for the most part when it’s above 70. I plan to have injectors tested . Hopefully it’s a turbo issue elrather than a ring.
smoke and vapor is one thing and could be caused by a number of things like oil brand, relative humidity, oil temp, oil age, lots of stuff. Actual blow by is pressure filling the crankcase most likely caused by rings not sealing. Like Knotty said if there is enough crankcase pressure to blow off the oil cap then you have excessive blow-by.
There was minimal blowby. Almost the same amount my 06 cummins had, which was what i would say, normal. There is excess vapor for sure, but the blow by seems normal for a diesel. When someone mentions the turbo seals, are they talking about the pedestal or the turbine shaft seals?
put oil cap on upside down, it should float on the neck and not blow off at idle or at 2k RPM

Though it does come out of the dipstick tube... lol

All seals, bearings and orings are included with a turbo rebuild kit from riffraff diesel including the pedestal orings.
