2008 Endeavor. I have been consistently losing engine oil for about 6 months. I have never had an oil spot under my Endeavor at any
location that I park for an extended time but I always seem to be low on oil. My last oil change was about 3 month ago. I added the
required 5 quarts of oil. One month later, I checked the level and added another quart to keep the level on the dipstick in acceptable range.
After the second month, again I added another quart of oil to bring the oil level back up. This makes a total of 7 quarts of oil in 2 months.
After the third month, just a couple of weeks ago, I drained the oil and only got a total of 4.5 quarts. Somewhere I am losing oil but I
don't see where.

Some background info, about 6 months ago I found engine oil in my spark plugs and coil packs when checking out a misfire engine code.
I removed both valve covers and replace both valve cover gaskets along with the tube seals for the spark plug tubes. I also replaced the
back 3 coil packs, since they are difficult to get to, and all 6 spark plugs. A few weeks after the above repairs, I began hearing a ticking
noise from under the hood each morning but only on cold mornings. The ticking noise only lasts for a few minutes before fading away.

I took my Endeavor to a local auto repair shop about 3 miles away, first thing in the morning so that they could hear the noise but it had
stopped time I got to the repair shop. I described the rapid ticking noise and they said that it could be a lifter sticking. They suggested
that I include in my next oil change a quart of Marvel Mystery oil to see if that helps.

I have since changed the oil, as described above, and replaced 1 quart of regular oil with the Mystery Oil. I am still getting the same
ticking noise each morning. I have noticed that the noise gets quieter if I put the truck into gear, either forward or reverse, and will get
louder again if put back into part.

Any ideas on where I might be losing my engine oil and if it could be related to the ticking noise?

All help and suggestions are very much appreciated.

my thoughts

About normal for the 8 year old mitsubishi engine over a month

One possibility is hardened valve stem seals on the valves
Lets small amounts of oil rundown and burn off

the egr could easily handle the vapors and recycle into the motor to re burn that amount without any sign out the tail pipe

I would say engine oil consumption depends on mileage.

Below 50.000 miles should be zero.

Above 100.000 miles expect to be burning oil.

All depends on how engine was treated - high rpms when cold means you wear pistons / cylinders quicker.
Means you start burning oil earlier - I always try to let the owner drive a car I intend to buy first.
That way I can get an idea how he treated the car ...

Thanks guys. Since I don't see any major or quick loss in oil, I will just keep a eye on the oil level and check it weekly to monitor any loss.

I have a 2011 Endeavor and I noticed I have to put a quart in about every 1000-1500 miles. The dealer said it was normal to burn 1 quart after 750 miles, but I find that a little far-fetched.

Any thoughts?

Read my previous post - depends on mileage and treatment - more info please.

Had a car with dying engine (piston, rings, cylinder worn out) - used 1 quart every 100 miles - used saved old oil ...

How about the PVC valve stuck open? Have you changed it lately? If stuck open it could be sucking the oil and burning it off.
