I had a leaky oil pan gasket on my 2010. I never saw oil in the driveway or on my back doing other stuff, but sure enough I could see where it was leaking on the lift. If you've got a warranty let the dealer do it. It cost me $60 with the CPO deductible.
I've read the 3.8s can leak from the rear of the intake manifold.
Where would it be disappearing to?
How's the compression?
It gets trapped on the bellhousing. It sounds like your consuming more oil than a bellhousing could be hiding though.
So my jeep is burning about 1.5 quarts every 1000 miles now. And I'm beginning to think this might be a little excessive. What is there to do in this situation? Other than just constantly refilling it with more oil
What year and how many miles ? 1 qt. per 1000 miles is the break point for repairs
based on the manufacturers consumption requirements. If the intake is leaking, it
can suck oil out and run it through the engine. I had this happen on my 94 Z28.
The intake gaskets allowed the intake runners to suck oil from the crankcase.
It's a 2010 with 61k miles this isn't good news for a college student [emoji20] I also get the oil changed every 3k miles
Are you checking the oil level after the oil change is done ? To properly check the level
you need to let the jeep sit for a few hours on level ground and pull the stick to verify
the level meets the requirement on the stick. Never checking it and hoping the oil change
joint is properly filling the engine isn't a good idea. Perform your own test and you might
check the PCV valve too. If it's stuck open, you could be consuming oil through it.
Check for blow-by too. After checking the PCV valve function, pop the oil fill cap with the engine
running and see if it's pushing crankcase pressure out of the fill neck. Otherwise, a compression
test and a leak-down test will be required to know what the actual fault is
I check it every 1000 miles and it's always low. Granted I don't let it sit for hours maybe 45-an hour but it is on level ground it's always way below the safe zone
As I said........ Are you checking it right after they change it ?
For now keep checking it and a compression test may not be a bad idea for peace of mind. The manufacturer will just give you a bullshit 'allowable limit' so they don't have to deal with consumption problems. A lot of them say a quart per 1000 miles is normal, and recommend 5000 mile intervals. So when you get your oil changed on a 5 qt system, if your pan is empty, you're 'within spec.' For now keep an eye on the level so you don't do damage, which sounds like you're already doing that.
No but next time I'll check because I'm going to be pissed if they're not using some of the oil I bring I always bring my synthetic and just have them change it for 12 bucks
