When my rebuilt engine was using oil the shop said to put 500 hours on it. I did that but it was still using a lot of oil so out it came.
there might be 200hrs on the new engine.When my rebuilt engine was using oil the shop said to put 500 hours on it. I did that but it was still using a lot of oil so out it came.
I will have a look, I am on the machine tomorrow.If you pull the dipstick or oil filler cap with it running is there visible smoke ? Was always a quick way to determine the state of the rings etc.
In the old days the breather tube told the tale but nowadays all that gets recirculated.
Thank youAt that rate your well over what Cat considers a problem . They use a 250 to 1 ratio of fuel to oil as a reportable failure.
They will want a record of fuel used to oil added for warranty. Your dealer should help you get the papers to fill out.
On a C7 heui I think there is a chance the high pressure oil can cross over to the fuel side of the injector past the seals so you may want to look at your fuel tank and see if it’s getting black at the end of the day.
There is 1 year warranty on the engine, not sure what our mobiles plan is but we will watch very closely on the oil and fuel usage for now on, with the history and problems with this machine we are making sure we get everything documented.Hell, that engine should be under warranty. Be careful what you screw with so they don't void your warranty...….it happens! I would be ringing CATS phone off the hook...….while not touching that engine.
There is a lot of visible smoke coming out of the oil filler tube, I checked today with the engine running.If you pull the dipstick or oil filler cap with it running is there visible smoke ? Was always a quick way to determine the state of the rings etc.

Well, that’s not a good sign.There is a lot of visible smoke coming out of the oil filler tube, I checked today with the engine running.

Might as well drive it to your CAT dealer and leave it there.My partner was out on the other shift on Saturday he burnt 300L of fuel and around 1 L of oil according to the dipstick this morning, but the motor seems to take spells where it will use 3-4 L of oil with that same amount of fuel burnt, I am out tomorrow morning for a full shift with the machine, it will be hard pushing, will see how it makes out.
20/80 emailed me the Serial Number. According to the system I can see when & where it was dyno tested, and it all fits with it being a Reman unit, unless someone is telling porkies.......I wonder if this engine was run on a dyno.
