Some suggestions'Cooler minds will prevail' has been some of the best advice on here. It took a day or two but im ready to get back at it. I do love working on the truck and as much as it stresses me out or generally ****** me off.
What quantity of oil in the intake would you consider a lot, or enough to be a leak? I have roughly a tablespoon at the intake of the turbo. I just assumed this was caused by blow by condensing there.
It never occured to me that the truck could be leaking and not have a puddle on the ground. I started paying extra attention after I read that and noticed tiny drops of oil where ever I drive... Im sure a good bit of my consumption is from that. I'll track it down and see where that leaves me.
1) Change your oil and filter. Go with Delo and see how things go for the next 3,000 miles. You will know then what your consumption looks like. If it does not improve and is not from the turbo or engine seals, you can make a better decision. I loose about 2 qts every 3,000 miles for reference.
2) A tablespoon in and around the turbo would be suspect. Clean things up and see what happens at 500mi and 1,000 miles. I will let you or those who have a turbo share if the cdr valve is upstream or downstream of the turbo. If upstream (Between air cleaner and turbo.) then the blowby could likely be your cause of oil in the turbo housing. If downstream it should not be the reason and likely the turbo is leaking at the shaft seals. But clean the area up and see how long it takes the oil to reappear in the turbo housing. Its suspect and if the turbo is leaking could be a big part of your consumption.(It’s under pressure.)
3) When you park at night put a piece of cardboard under the engine and tranny. 3 drips when you park overnight is not going to be a quart of oil or atf every 100 miles, but a puddle every night would be causing a noticeable loss of oil. The card board will also help you zero in on where your leak is. Valve covers tend to be a very common leak on these trucks.
4) When engines sit for two years they can rust, corrode, or gum up. Often running them for 100-2,000 miles let’s them work it out. So the blow by might be temporary so give it some time. The hot shot may also have thinned the oil and is not helping with consumption.(But may help with stuck rings.). Delo has detergents too that can help.
As you have read oil consumption varies by owner. A quart every 500mi even I would live with. These engines are known for being simple, strong, and reliable. But also for drinking some oil along the way. I am optimistic a oil change will dramatically slow your consumption. I am hopeful in another 500-1,000 miles you start seeing an improvement as rings and other items clean up.
