New Jeep engines Being Made in China

Hi Everyone

I'm looking to buy a jeep. I've always wanted one and I started doing some research ect. I came across this article on Wikipedia

AMC Straight-6 engine - Wikipedia, the free encyclopedia

and wanted to ask if any one has noticed a difference in the quality, durability, reliability on the new jeep engines that are being made in China? From this article the engines in the new jeeps 2007-thru today use the Chrysler's 3.8 L OHV V6 made in China. Prior to that they used the 4.0 straight 6 (please correct me if I am wrong) made in Ohio. I'm wondering if it would be best if I just bought an older jeep prior to 2007 and made upgrades myself.

Thank you for your input and suggestions. I'm doing some research and plan to buy a jeep by March 2010. I just need to decide whether to get a new one or not.

I read that in line 6's are still being built in China, although they were never OE. The current OE V-6's are not built in China.

2004 Black X 4.0, auto, 3.73's, soft top 31-10.5-15 Toyo A/T's on 8" Ultra 175's, 2" Teraflex BB.

No sweat, Shipmate! It's made in Michigan! Here's a blurb from Wikipedia:

The 3.3 was bored and stroked (3.78 in/96 mm and 3.43 in/87 mm respectively) to create a 3.8 L (230.5 CID/3778 cc) variant.[1]
This EGH version is built at Trenton Engine in Trenton, MI.

The 3.8 got an increase in power of 12 hp (9 kW), for a total of 162 hp (121 kW) in 1994 via a new intake system. In 1998 the compression ratio increased for a total of 180 hp (134 kW) and 240 ft·lbf (325 N·m). In 2001, the engine got a Variable Intake System which boosted output to 215 hp (160 kW) at 5000 rpm with 245 ft·lbf (332 N·m) of torque at 4000 rpm.

Vehicles using the 3.8 include:

1991-1993 Chrysler New Yorker and Chrysler Imperial 150 hp (112 kW), 213 ft·lbf (289 N·m)
1994-present Chrysler minivans
2007-present Chrysler Pacifica

2007-present Jeep Wrangler

Look at your link that you provided. Under the Header "4.0", go to the last paragraph, just before it shows the Vehicles that the 4.0 is used in. Look for this sentence: It was discontinued at the end of the 2006 model year and the redesigned 2007 and onward JK Jeep Wranglers use Chrysler's 3.8 L OHV V6., and you'll notice that the 3.8 OHV V6 is a clickable link. It redirects you to the other info I posted above.

Best of Luck!
