Early GM 2.4L Ecotec engines use port fuel. It can then stick to intake valves and ports and form carbon deposits. All engines naturally produce some oil blow-by that makes its way through the intake tract. But most importantly, all of them prove that an engine doesn't need to have hundreds of horsepower and many cylinders to qualify as a legendary powerplant. Carbon build-up on the 2.4 Ecotec is a problem that mostly affects the LAF, LEA, and LUK engines. Some of them are known for their amazing power output, others for their reliability. For years, four-cylinder engines have been associated with basic, uninspiring "Point A to Point B" cars or the cheapest trim levels.Īnd while it's partially true, there are nevertheless true gems among four-cylinder engines. To many enthusiasts, admitting that you like four-pots is similar to donking-out a classic muscle car - very poor taste. I never even gave a thought to engines before because Im more of a 'I get a car to drive it, not make high payments, or show it off'. The distributor is driven directly from the front end of the camshaft. Steel cylinder sleeves are used, which are easily replaced when rebuilding the engine. If you want to buy a car with a four-cylinder under the hood, or just need an engine to swap into a project, these are the ones to go for.Īnd in the heart of this love affair with the big, loud powerplants, many car enthusiasts seem to completely overlook the smaller, more rational four-cylinder engines. Love the difference between 2.0 and 2.4 I just traded in my 2011 Jeep Patriot (2.0 liter engine) for a 2014 Jeep Patriot (2.4 liter engine) and boy do I notice the 'pick up' difference. I and 2) is Of the L-head type, having all cylinders and the upper half Of the crankcase cast in one piece. Updated April 2021: This list was updated to include more legendary four-cylinder engines, as well as more recent and up-to-date information.

2016 Equinox LT AWD/ 3.6 V6 /Patriot Blue 2017 Colorado LT 4WD Extended Cab/ 3.6 V6/ Silver Ice Metallic. And it's easy to love these engines - they are powerful statements to the ingenuity of automotive engineering that best represent our desire for speed and performance. engine in the Equinox and Terrain was a complete disaster for GM and an engine that everyone should run away from. All car enthusiasts love the robust, balanced straight-sixes, the big and brawny V8s, and the screaming V12s.
