Well, I changed my oil and only added 14.5 quarts. I let the oil drain forever. The dipstick looked good as well. I went on a trip, about 500 miles roundtrip, and today, I check the dipstick and the oil level is about .5 inches above the "full" line. What gives? I was on an incline (front of the vehicle up ) when I checked the dipstick, so I don't know if that has anything to do with it. I didn't even put 15 quarts in! Any help would be great. Thanks.

 

You may have been on an incline. When I change mine, I only add 14-Quarts which includes enough for the filter replacement. With the 14-Quarts, my dipstick shows at the top (Full) mark.

I do have limited experience as this is my first PSD (2-Months). I'm sure others will chime in soon with a better perspective.

 

If you have too much oil it can foam-up and make your truck run crappy.

Smell the oil for diesel odor, could be fuel getting into the oil.

Is the oil still clear, no greenish tint or frothing, could be coolant getting into the oil.

Some early 95 and older engines (I know, not yours, you never know) were equipped with a 12 quart dipstick. (If yours is stamped 1820068C1, REPLACE IT!, it reads 2 qts too low!!!)

If you are just dealing with overfilling with oil, then drain.. If it is too overfull your crankshaft and connecting rods will spin, slap the oil, and create air bubbles in the oil which will in turn reduce the lubercation of the oil because of the air pockets. If the oilpan is overfull just drain some out, untill it reads full one the dipstick.

 

14 quarts in mine and it reads fine. I've also overfilled mine without a problem. Who knows why it did it. Don't worry.

 

I definitely wouldn't worry about it. With 14.5 qts of oil you're not overfilled regardless of what the dipstick says. Besides, with a baffled oil pan you would have to be way overfull before the crankshaft could get into the oil.

 

i would keep an eye on the level and maybe even send it in for a oil analysis if the level keeps rising.

 

If you ever do overfill, a fumoto drain valve is a very good thing to have.

 

When you drain it, on a flat surface, does all of the oil come out?

 

in reality, no. when you change your oil, only 75-80% of it comes out. the rest is still stuck in the oil rails in the heads, the HPOP and LPOP oil pumps and lines/galleries, and about a quart is in the HPOP reservoir.

that is why the oil gets black so quickly after a change, because it all mixes in. the color usually has little to do with the amount of additives left in the oil.

 

That is why I change mine before it needs it. Like I said, the worst oil I have seen in my engine was when I did my HPX install. Not black but far from what I normally drain out. I was tempted to suction that crap out and refill right at the port with fresh. I know, **** but I hate the look of that oil in a dead end spot powering my injectors.

 

Tenn,

I wasn't aware that the injection galley was dead end from the HPOP. You made a good point! How can we get that oil replaced with new if it is continually there and does not circulate?

 

There you have it. No way to build the required pressure without a dead end. Someday I will clean mine out. Probably when I get injectors rebuilt. Or you could booger up your injector orings. That'll keep the fresh oil coming. OK, bad idea.

Edit: here's my real burn with it, just think about that same oil in the galley year after year. Heat cycle after heat cycle, just going nowhere. Well, going nowhere if all is working right. Driving those overexpensive injectors time and again.........I think you get my point.

 

From the Manual:
During initial start or cold start, the high-pressure oil pump (6600) receives unfiltered oil from the left side valve lifter oil gallery through the anti-drain back check ball valve. Once the engine starts or during warm engine starts, the check ball closes and the high-pressure oil pump receives filtered oil from the high-pressure oil pump reservoir. The high-pressure oil pump pumps the oil under extremely high pressures (4,115-20,577 kPa [600-3,000 psi]) through the left and right side high-pressure supply hoses to the high-pressure oil rails (integral to the cylinder heads). Once in the oil rail, the oil is fed to the fuel injector bores through four oil feed galleries drilled and machined in the cylinder head. The high-pressure oil then actuates the fuel injectors.

After Firing the injectors the oil joins the low pressure system and drains back to the pan

 

Man Alan, do you ever sleep? Just kidding. I've seen and heard that. Just how does that oil retun after firing the injector and maintain injector firing pressure? Skip the manual crap unless it illustrates this. Must be a very high pressure check/control valve that knows when the engine is no longer running and somehow replaces that old with fresh so that the truck would be ready to start the next time.

Not trying to be a Richard Head but I don't see it. Maybe I better look my DVD over again. I know what it says but the diagram does not illustrate it. Did I miss it?
