Burning oil loosing a quart a month??? HELP... - Page 2 - PeachParts Mercedes-Benz Forum

I like the idea of pulling the injectors and soaking them for 24 hours in Marvels. Another person mentioned to shoot some down in to the cylinders..

-How much?

-How long to let it sit.. Hours?.. A day?/

-Do I run it for a while (how long, miles?) then change the oil and fiter and see how much crud comes out??

I'd start with fixing the low oil warning sender, then run until the oil level hits the add mark, should be able to get ~6000 miles or more on an OM60x engine.

If you find that you're burning more than 1qt in 2000 miles, then look into where the oil's going.

How many miles during that month?
**1500-1800 before the light and dipstick are lower than FULL.

Did you run Marvel through the fuel or did you remove the injectors and squirt some in and let it set overnight? The latter worked well for me...compression up and oil use down.
**Yes, I ran 1/2 bottle of Marvels through the gas tank. Not much gain in oil loss.

Have you checked your turbo for play? Your turbo could be using oil.

**I have no idea how to "check the turbo for play"... Do tell....

If the "add oil" warning comes on when the oil on the dipstick is almost full, the problem could be the float switch in the sump could be faulty. It's a common failure item in high-mileage 60x engines. The warning should not appear until the oil is at the "low" mark, 2 quarts down. About $40 for a new switch and you can install it yourself next time you change oil.
If the dipstick is correct, you are over-filling the crankcase. The excess oil is likely being burned off, that's why the level keeps falling.

**On my lunch hour I went out and took a look. I added a quart yesterday and its sitting right at the full mark.
Before I filled it up the "add oil" light came on so when I got home I checked it. I'm using my calibrated eyeball so bear with me. The distance from the Full to add line is apprx an inch or so.
Before I added oil the level was about 1/8 the difference between the add and full.
To ensure I don’t overfill it should I wait until the level is HALFWAY between the hash marks? And kind of ignore the light?

** I'm guessing the one fellow hit it on the head when he said the float was bad an I'm overfilling it.

I also like the idea of pulling the injectors letting the soak and putting some marvels in the cylinders to also let them soak.

Thanks Chris

Ill do a few of these and keep yall posted..

If you put the Marvel M Oil in the Fuel it will just burn and have no effect on the Rings.

When I soaked my Cylinders/Pistons in Mervel M Oil I poured in in through the Glow Plug Holes (so I would not have to buy new heat shields).

However, the key to using it is to give it time.

I soaked mine for al full 7 day week and rotated the Engine and poured somemore in. '
I soaked it for another 3 days at which point I had to get the Car Back in use; did an Oil and Filter change and started driving it.

I worked and cured the hazy grey smoke I had been putting out at idle and normal driving.

When I used the Marvel M Oil on my Volvo Diesel Itried to get 1/4 Cup per Cylinder through the Glow Plug Hole. Howere, if you are at top dead center the whole 1/4 cup is not going in. I soaked for 1 week rotated the Engine and soaked for another 3 days.
Here is a thread on it.

WOW.. great info.. thanks guys.

Unfortunatally, I dont have a WEEK...more like a weekend.. (its my GET TO WORK Car) I have to pull out a dead glow plug anyway and Ill try it.

Just put some in the glow holes... let it sit.. put the plugs back in and hit the road or do the oil change at the same time?

babymog · #21 10-07-2010, 10:49 PM

I think that you're missing the point:

From what you say, your oil light is coming on before the oil is down to the add mark, PROBLEM WITH THE OIL LEVEL SENDER.

Again from what you've posted, you're burning approximately 1/2 quart in 1500-1800 miles when filled to or slightly above the full mark, A QUART IN 3000-4000 MILES WHEN OVER-FILLED IS NORMAL.

Fix the oil sender, measure the miles from oil change to 1quart low or to the add mark.

disbo100 · #22 10-13-2010, 09:41 AM

Hey guys,

Well I pulled the glow plugs and put in some marvels.. Let it soak about a 2 days and put her back together. Then I ran it for a while and changed to oil hopefully pulling out some goo...

It was very strange starting it up that first time with all the oil in the cylinders.. WOW that was a LOT OF SMOKE.

I followed yalls directions topped off the oil and Ill keep an eye on it until it gets to the "add mark" on the dipstick and not worry about the light.
So far Ive put 500 miles on it and the oil level is the same. She seems to have MUCH more pick up than before and rides smoother..
Ill check in after a few thousand miles and let you know what happens.
If a 4 .00 bottle of Marvels did this much good.. Im very excited to see if slows my consumption of oil... Or stops it
Thanks for all the good ideas

Chris

Good to here. I just added the first Quart to mine at 1897 miles after oil change. I know that is a little sooner than some but not excessive in my book. After the rest of the mechanical stuff is done I will dig into the engine

disbo100 · #24 10-21-2010, 09:26 AM

I made it to about 1000 miles before I was down to the middle of the dipstick.

I understand that if the oil was at the "add mark" then it would be 2 quarts down

Im assuming that is down 1 quart?

OUCH.
NO
don't do this!!!
sorry I did not see the thread earlier...
yes put the mmo in the glow plug holes.
yes let it soak for as long (days) as possible.
NO DO NOT JUST PUT THE PLUGS BACK IN AND START THE CAR WITH THE MMO IN THERE!!!!!
you must leave the GP"s out and spin the motor over several revolutions first, to be sure there is no liquid in the cylinders that will BEND YOUR RODS!!!!!!!
you may have gotten lucky, you may have ruined your motor. not sure, cross your fingers.

NEVER attempt to start your motor with fluid in the chambers!

down to the middle of the dipstick is where many vehicles sit with oil level.
drive it another 1000 and check it. if it's still in the middle, you are golden.
remember to fill it to that level only.
if it's down to the low mark, then your oil consumption/loss is troubling.

babymog · #27 10-21-2010, 10:19 AM

Not to disagree with John, he's one of around a dozen people on this forum who are almost always 100% accurate but:

Out of 12 602/603/103/104 cars I have NEVER had any oil consumption issues when filled to (and slightly above) the full mark, I always change oil and filter, fill to full, and it stays there. Current car has 204,000 on the clock, time for its change at 6000miles and it has made its way down to the middle between the marks, very slowly over these miles. It has a leak so it's not burning (all of) this oil.

If through the years of development and testing the OM603.960 before being installed and delivered in your car they would have found that the oil level was too high, they would have changed it. Further, I doubt that my 4 603s are all anomolies. The 603.970 is a different story, the longer stroke required a windage tray.

Fill it when you change it, don't add until it hits the add mark (unless you're embarking on a trip where you expect to need oil or otherwise are just OCD-ish).

That said, if you are not leaking oil, no oil on the pavement/engine/in the coolant/etc., 1qt/1000miles is high in my experience, but not tear-down time. Could be leaking through the headgasket into cylinder #1, usually this will show significant blowby, could be leaking/burning in the turbo through bad seals which usually shows in lots of oily residue between the turbo and the breather inlet, could be valve seals which will usually show as blue smoke on startup and when idling down on a grade or to a stop. The first two could become critical, the valve seals not such a big deal. If you remove the intake manifold check all of the runners for oil (back to the turbo), and look at the valve stems for cruddy partially-burned oil residue. Where evidence of this oil starts will tell you a lot: Starts at the turbo = turbo seal, starts at the oil breather and lots of blowby = head gasket (probably) between the timing chain and #1, nothing significant but some cruddy valve stems = bad valve seals.

It can also be rings, but it is in my experience the least likely, the bottom of the OM603.96x is pretty well overbuilt. If it is, it will show in a compression test, and usually some hard starting (on one or more cylinders) will result. Sticking rings is far more likely from alternate fuel use or other unusual circumstances, which some have cured with the MMO treatment mentioned above, ... sticking rings can and usually do eventually result in scored cylinders or worse.

oh, I'm not saying it's normal for 603's in general, I've barely gotten 1000 miles on my first 603 experiance... but I'm saying he should give it another 1000 miles and see if it stops or continues to drop.
if it's stopped at the 1/2 mark, his car may be a tad worn, and blowby/windage/what have you, may be causing the oil to froth a tad, and loose a smidge during drive. heck, the OP may be using lucas additive which causes oil frothing and that could explain the oil loss!

if it keeps dropping (which it sounds like from your experience it will) more steps are going to be needed to curb it's lubrication appetite!

100% agree.

disbo100 · #30 11-03-2010, 12:55 PM

Well, Ive run it for a while now and I think the Marvels helped.

Im going through a quart about every 1500-1800 miles.

From what Ive heard that aint bad for a car with that many miles.??

** I did run the starter a few times to get the liquid out of the cyl before I put the glow plugs back in.

Good tip...
