I am not sure what to say or think. The reman engine is way past breakin. I almost never do short trips, usually 30-40 minutes. I have used the remote starter a few (very cold) times, but then drive it the 30-40 minutes. The T6 seems to have done better than PU for the most part. Not sure whats up with the fuel dilution.

There is an oil cap on the engine, not a solvent cap.

I'm havine trouble reading the report but from what I can see.Something is coming apart! It's made of metal, I think it's gotten into your bearings from the lead and copper in the report. The 4.0 throws some iron but not tripple didgits, maybe 20-30ppm at the most.

Your airfilter or it's tubing isnt sealed well either but that just a small issue for now. Is this engine still under warranty of any kind?

Read the bottom set of numbers, its the most recent with T6 oil. Its past warranty. I have checked the air intake system several times and do not see any problems. The air filter is relatively new, the breather hose and elbow have been replaced along with the PCV, grommet and hose.

The copper is a little high, but not the lead. I would expect both high if a bearing. No oil cooler in this vehicle. So where is the copper coming from? I read some place it can come via a fuel line, but that seems a stretch.

Any chance the Fumoto oil change valve is where the copper is coming from? Its brass.

I was considering replacing the injectors anyway.

I do not consider the TBN low at all.

Thats the best run you've had. I can't read the iron, 36? The aluminum is fantastic though at 1 ppm always a concern in these.

The copper is odd. At this point you've used an oil well known to produce stellar UOA's in the 4.0 so I don't think you're going to do any better oil wise at this point. Your reman just seems to have a rather unique base line I guess.

From what I can see, I think sample #1 is the triple digits for Iron, and it has come down nicely since then. My 4.0 throws around 21 ppm Iron in 5000 miles so it's breaking in nicely, as far as Iron is concerned.

Fuel dilution, on the other hand....what head do you have on the engine? Was it reused in the rebuild and is it an 0331 casting?

The engine was a complete reman from Marshall Engines just needing tin. The head is whatever they used.

The rotella run looks fine other than your cold starts are brutal. You might throw in an italian tuneup every few thousand miles to really burn that gas out of the oil or stop with the cold start idling.

So lets say I remote start my Jeep and let it run 5 minutes, then drive at 40 to 60 MPH for 30 minutes. Won't it have "burned" off any fuel that was in the oil?

Should have, unless your thermostat is keeping things too cool.

But an italian tune up's purpose is to get things hot, not warm, so higher load, acceleration runs, up a mountain etc are what you want.

Or drop a gear/hold a lower gear a bit more when you can and let it purr a bit more.

Looking back for other Jeep 4.0 engines I found one UOA with 2 @ 3500 and another one with 6 @ 3500 miles. So mine is 16 at 5000 so significantly higher.
