Is a 2002 Chevy Cavalier an interference engine?
Contact a chevy dealer and give them the Vehicle Identification Number for your 2002 Cavalier 2.2 and they can tell you the details on the engine fitted. Your Cavalier is an interference engine. I have seen a few with bent valves when the timing chain failed. It’s a common problem on the 2.2 and 2.4 also.
Is a 2.4 L Ecotec interference engine?
To make matters worse, the 2.4 Ecotec is an interference engine. This means there is overlap in the travel of the valves and pistons. When timing jumps it can cause the valves to actually contact the pistons. It’s a good idea to check the GM 2.4L Ecotec timing chain for any marks/scuffing or slack.
Is a 2.2 Chevy engine good?
2.2 Ecotec Reliability Overall, the 2.2 Ecotec is a very reliable engine. 2004 and prior models tend to be less reliable due to the commonality of timing chain failure. 2005 and onwards models don’t really have any common problems outside of general maintenance items once the engine reaches high mileage.
What is Ecotec TEChnology?
Ecotec (capitalized ECOTEC, from ‘Emissions Control Optimization TEChnology’) is a General Motors (GM) and Opel Automobile GmbH (Opel) trademark that refers to a series of emissions technologies that were implemented throughout a range of GM engines.
What is a Chevy Ecotec engine?
The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.4 and 2.5 litres. While these engines were based on the GM Family II engine, the architecture was substantially re-engineered for the new Ecotec application produced since 2000.
What is 2.2 Ecotec engine?
The Ecotec 2.2-liter engine features a modular design, providing flexibility for a number of future technologies such as turbocharging, variable valve timing and direct injection-gasoline. Low maintenance is another key hallmark of this engine: oil and filter replacement is the only routine service required.
What’s the difference between an interference motor and a non-interference motor?
Interference engines are 4-stroke engines that open one or more valves to fully accommodate the area in which the pistons enter. In comparison, non-interference engines feature pistons that do not travel into the open valves.
