Pros and Cons of the 2.2L Ecotec L61

Hi, new user here. I did a search of this topic but found nothing. Anyway I'd be interested to know what you all think of this engine in general and what its strengths and weaknesses are.

One weakness was the first timing chain tensioner design up to 08 when they came out with a ''B'' version. If you have the older design I strongly recommend you change to the newer design. Newer design has a dimple on the head. Also this engine likes oil at the full mark for better timing chain lubrication. Other than that all Pros

Well, in my opinion...

Pros:
  • Low cost of the engine/car itself
  • Fuel Economy
  • Reliability
  • Ease & low cost of maintenance
  • Strong Internals on certain model years

Cons:
  • Timing Chain Tensioner (as Coby explained)
  • Lack of Variable Valve Timing
  • Less power than LSJ/LNF/LE5/LAP
  • Weaker internals in 2008
  • Expensive, unused electronic camshaft actuator (VVT not present, but half the parts are there)
  • No tuning available for the 2005 & 2006 ECM module.


Overall, I think the pros far outweigh the (admittedly picky) cons. Plus, some of the cons I listed should only be concerns if you plan on boosting the car. For a reliable daily driver, it's hard to go wrong with an L61 powered Cobalt.

When I bought my 08 the first thing I wanted to do was replace the tensioner. I was too late it had already fallen apart and fallen in the cavity in front of the cover. Lucky for me' I was able to gather all the loose parts with a rod magnet and avoid hell. Also lucky for me the chain hadn't jumped. Replaced the tensioner, topped off the oil and it was as good as new.

If it still has the old style tensioner definitely replace it asap, mine fell apart when I pulled it out and I only had like 60k miles on it at the time.

What do you think the total time start to finish and reasonable parts cost?

If you don't have to fish pieces out of the engine, like a half hour or so you could have it done. It's not too expensive either, I think I paid 25 for mine

My 08 still had the old style but mine was an early 08, pretty sure they switched mid 08 some time so your 09 should be okay. Takes 2 seconds to check though, reach back there and feel it. If it's flat it's the old style and if it has a bump on it, it's the new style

Tensioner was about $75 Cdn and swap time depends if the tensioner is still together or has fallen apart. 20 minutes if it's still intack and 1-3 hours if it has fallen apart. My 07 took about 20 minutes and my 08 took about 2 hours because I had to fish the tip and the spring from the front of the timing chain cover. It would have taken longer if these had fallen to the bottom of the front of the timing chain cover.
