well i had the intake tube off and there is a decent amount of blow by...then i check out the other side of the turbo and there is oil in there also???????

figured that BUT......

it's a decent amount.....ill see if i can get a pic tom.

ya i did the crank case bypass mod and it dumps out into a catch bucket in the bottom of my air box. I usually have about a inch or two of oil accumulate in it every 3-4k. If your not using a ton of oil I wouldnt worry about it. unless your truck smokes (burnt oil, not coal) when you drive.

Your description isn't necessarily cause for alarm. There will be some blowby and it doesn't take much to accumulate in the intake piping over time. I agree with OregonStroker....if it isn't burning oil or low on compression, I don't think I would worry about it.

well im losing about half a quart every to weeks....its dumping coal not white smoke.....so i can just run it to a catch can like a gas engine

If the blowby is smooth and even - that is just wear. If it is chugging - something broke. I use about a gallon every 3k miles.

yea thats about what i use....so it is normal?


the truck runs fine

[dbkerley]

Normal? IDK

It is what mine does and it doesn't have any issues. I could probably lower it by plugging some leaks. But, I'm waiting for something to happen that will make me pull the engine first.

mine doesnt drip a bit of oil on the ground.....
