2.7 L Engine

Pretend the 2.7L is an illegal drug and "just say no". The engine has some serious issues and isn't worth taking the risk on.

Sludge is the biggest issue. Even when perfectly maintained this engine tends to sludge up. Some people are using only synthetic oil with more frequent changes to try to avoid the issue but only time will tell. Cam bearing failures tend to be common as well... Search google for "chrysler 2.7l sludge" and read until your hearts content.

Chrysler should cover any failure under warranty. If you decide to get one make sure the oil is changed every 3k exactly and keep all recipts! Good luck whatever you decide.

Sure they're covered by warranty -- as long as the warranty lasts and *if* you can prove you did maintenance to the satisfaction of the zone manager. Why set yourself up for the hassle? It's not nearly as good an engine as others are.

Then I would be much better off with a 2.4 or 2.0 4-cyl or a 3.5L 6 .. Thanks.. we'll look for those. I can't believe that Daimler-Chrysler would keep such a problem child in production...pity...

Thanks for the warn>

I'm surprised too..it's the base engine on the new 300. I'm also surprised that they'd keep using it with the relatively long warranty coverage if it were as much of a problem as it seems to be.

Is the 2.5L still available for the Stratus, or did the 2.7 replace it? Another option would be the 2.4.

My '99 Concorde with 2.7L is chugging along quite well at 125+k miles. It gets 80 miles a day of highway driving, regular oil change and filter change (with every oil change), and an additive as a pre-emptive against sludge. I bought it used at 58k miles. I would say that buying one used without knowing its history is something akin to Russian roulette, though, based on numerous accounts on various forums, it seems that if they're going to let loose, it generally happens in the neighborhood of

Wife has a 2004 Sebring Limited, has 7100 miles on it now, taking it this morning for it's 3rd oil change. Dealer does the oil change. U mentioned an additive along with oil and filter in your Concorde. What additive do u use ???

TIA

I put 1/4 qt. of Marvel Mystery Oil in the crankcase with each oil change (and change the filter with each oil change). Others report good success with a similar product called Sea Foam (in display areas of many auto parts stores). Alternatively, you may want to switch to synthetic instead - now's the time to make the switch if you're going to. If I was going to go to synth, I'd make my own blend by using 1 or 2 qts. non-synth to 4 or 3 qts. of synth (don't buy a commercial blend, because you don't know the proportions, and I guarantee you any uncertainty will be exploited by the manufacturer as far as pricing).

A common misconception. Commercial blends are on the shelf now.

But is it a special mixture? Is it the same as simply mixing consumer synthetic and conventional oil off the shelf?

The fact of the matter is, my dealership warned me against mixing the two as well (without explanation) and I did not take your advice to phase it in. I've got about 3500 miles on my first synth job. I believe I will stick to about this range with a new filter even with the synthetic.

I'm starting to wonder just how prevalent the 2.7l problem is. I mean, I've known about it for about 6 months now, and I have yet to talk to someone, or read a post in here, etc., from someone who had theirs fail. Maybe it's just an unreasonable percentage of premature failures, but small nonetheless (e.g., less than maybe 20%). I'd sure like to see some hard statistics.

BTW, how did your crank look when you took you oil pan off?

Fairy tales can come true, it can hppen you. . . . .

Dilute - possibly. Cancel - no. However, there are supposedly some areas where non-synth is better than synth (something about piston scuffing from an article I read some years ago), and together they cover the bases. But it would not cancel the benefits.

I don't think that the incentive behind commecial blends is purely to lower the cost of the oil itself. There are supposedly some synergistic technical benefits in a blend.

The 2.7 is the six available in the current Stratus sedan, and the 2.4 is the four. The Stratus coupe, made by Mitsubishi in Illinois has a
