Oil issues

So I overshot my oil change mileage by about 1500miles, and I ended up only having 1-2 quarts left. Is this normal?

Not normal. Either leaking or engine consuming oil.

I assume the engine burning oil is a bad thing?

If there is a small leak on the engine block, would that be an easy fix?

Some 3.8L engines are notorious for oil consumption. Just check the oil level frequently and keep it at the full mark

Depends on what was leaking and the location.

It may be leaking (check your garage or where you park for spots) or burning it, which means you have some engine wear.

The 2 Chrysler's I've had for a long time, both burned oil. The 318 in a Dodge Dakota burned about a quart every 3k miles and my 4.7 in a Grand Cherokee did about the same but had a small leak as well. Once your motor has high mileage you will most likely burn some oil.

Many of the 3.8's are known to burn lots of oil. Mine did. I used seafoam and changed to 10w-30 from the 5w-20, and after 1000 miles I haven't lost any oil. Expected to loosed 1-1.5 qts in that time period, so hopefully mine is doing better. Some people are afraid if seafoam, so google it and decide if you want to try it.

Probably wouldn't hurt to replace the PCV valve. A clogged PCV can contribute to oil loss.

Unfortunately it's a common problem with the 2007 and 2008 3.8L V6's From what I understand (I just had to put a brand new long block in my '08 X JK) at about 51k miles it started losing oil. I did not know anything about the issues, but it seems that there is an issue with cylinders 4 and 6 with clogs and the rings. oil ends up leaking into the cylinders. Both my 4 and 6 bearings were not getting lubed even though I kept on top of the issue and it was only one oil change from the start of the problem to the demise of the motor. DO NOT WAIT! get it in the shop or get rid of it. I traded mine in with 0 miles on the new motor. It was never gonna be worth more than it was right then. Good luck brother! Sorry to hear you are having troubles! Side note, and I can not confirm, but the issues seem to be happening to the motors assembled in Mexico. You can find out by the number on your block where yours was built.

"The Pentastar engines are made in Trenton, Michigan and Saltillo, Mexico. The Saltillo plant is set to begin production in the 2012 model year (with parts machined in Toledo, Ohio)."

I bet most or all of the Pentastar engines are also assembled in Mexico (even though we are talking about the 3.8).

Why don't you state where they are machined and where they are assembled then? Then prove it. I read that on Wiki, I definitely hope mine had nothing to do with Mexico. Hoping you are right.

October 14, 2011 update
Sources say that thousands of engines, including over 500 which were recalled, were built in Mexico using improperly maintained equipment; these engines are being repaired or replaced entirely. This is said to be the reason for shutting down the Windsor minivan plant despite a backlog of orders. The former head of Chrysler Mexico was dismissed shortly after this. This does show that Chrysler cares enough about quality to stop those engines from reaching customers, at great cost. It might also tip the balance to install a new engine assembly line at Trenton North; a cam line was already installed there after a Mexican supplier was unable to provide the needed quantities.

Chrysler also re-opened part of the Trenton North plant, which most recently made 3.3 and 3.8 liter V6 engines, to make parts for the Pentastar — some of which are currently made by a Mexican supplier. A full assembly line will be installed in Trenton North as well. Some of the 3.7 liter production equipment moved to Trenton, for Pentastar V6 use. By January 27, 2012, one million Pentastar engines had been made.


I think at very least, some of the parts are outsourced.

Look at paragraph 2 of the info you quoted. The PStars in our JKs are built in Trenton, MI.

Here is a link to updated info (like the 1 Millionth Pentastar being built at this plant): http://media.chrysler.com/newsreleas...=11934&mid=261

If you still have the window sticker from when your Jeep was new you will see the engine was built in the US of A.

But not important enough to argue about it. If you want to believe/bet they are made in Mexico, go for it.
