I think it is funny that people say the 2.4L DOHC and the Ecotec are "basically the same engine". No. No, no, no. Those who spend alot of time working on these engines know that. The 2.4L is an older design. Compared to most engines out there, including the 2.2L OHV and 2.2L Eco, the 2.4L is a pretty crappy engine. It is unreliable, it blows the bottom end quite often. Head gaskets are very common, and unlike the OHV, they are time consuming, and expensive to fix. Many burn oil like nobodies business, they are very well known for this.
On the other hand, the 2.2L Ecotec DOHC is a fresh design, not related in any way to the old 2.4L. Much more reliable, with better torque curve characteristics. More fuel efficient, lower emissions, better all around. The only way they are similar is in the direct singlular numbers. Unless you know what you are talking about.... Don't say that Eco = 2.4L, because the Ecotec is a much, much, much better engine all around.
So why did you make this post exactly? Not everything you say is true. Head gasket issues? I have owned many 2.4's, and worked on many more never seen a blown headgasket.
I have seen some spun rod bearings but all but one I can say was low on oil.
I will admit the 2.4 is not prefect.
I have seen a OHV @!#$ the rod bearings out of the rod cap and it looked like paper. It was not low on oil.
the 2.4, OHV, and Ecotec are all good motors if taking care of, and can all be fun to drive.

Im just going to assume you dont know what the hell you are spewing out of your mouth. You are wrong on damn near everything you say about the 2.4.
I guess I should get rid of my 98 since it still has the original 2.4 in it. Maybe the 220k mile 2.4 in my 02 is junk as well. As far as I know it still has the original bearings in it (i picked it up used with about 190K on it).
He's just mad that in another thread he called me "unqualified to touch cars" and then i listed my current profession, with all the certifications and the degree that backs it up.
makes sence since he stopped answering after i said that up until now... and i've been saying the ld9 and the eco are = in terms of performance and where you can take them.
unfortunently for the O.P. there are more people on here that can 'discredit' what comes out of the O.P. mouth.
did you really think you could post this without getting slaughtered? No one likes to be told that the time and money they spend was on a sh*tty engine. Everyone is proud of what they build, drive, and race. Furthermore, all engines have their pros and cons; including the eco (especially when you're trying to find a cheap clutch for one). That's why we have more than 1 type of car and 1 type of engine. There isnt enough room on this forum for non-productive rants. But if you must; maybe the general forum? That way, those who want to actually accomplish something don't have to listen.

Sorry if I missed it... but where did anyone call the 2.4L Twin Cam (LD9) engine an Ecotec? Or vice versa?
I've seen lots of confusion between the 2.2L and the 2.2L... and the 2.2L.... but not the Quad 4 LD2 or LD9...

um i love my 2.4 ld9 an the only thing i had to change (thxs to whitecav) was the injector o-rings and that was it! SO yeah thats pretty reliable to
further... since i didn't post this in my above post...
i've owned a car with a 2.4 motor since 2005. in this time i have never blown a head gasket, and my motor has never consumed oil. (i've had it leak from the timing chain cover, but never burned it)
the only motor problem i have had was my own fault. there was a period of time where i pushed the oil longer than i should have, and mixed with the slow timing cover leak, i let the oil run low, causing the number 1 and 2 rod bearings to "tick" .... mis-diaging this tick as in the valve train, i stepped up to royal purple 20w50 oil (as mobil 1 15w50 quieted the tick considerably). shortly thereafter, one of my lash adjusters froze due to the heavy weighted oil, and bent a valve, destroying the exhaust cam and cam tower. i replaced the head with one that i had fully P&P and brand new valve train componants, and replaced the exhaust cam with an HO exhaust cam (i had been already running the 95 lo intake cam), started it up... still had the tick... by the time the tick turned in to a rod knock, 2 years had elapsed since the tick began... and by then i was ready to build my performance build that i now have. (listed in my profile)
so all of my ld9 issues were my fault... if you well maintain the engine, it will not fail any sooner than the eco.
further, my 2000 Z24 has always got better gas milage than my brother's 2004 base.
If you want to talk about fresh design try this. Look up the history on the Quad family. Never mind how much power they made, but how they did not have to run extra emissions junk because of efficiency. They got a bad rap because people were lazy and let them blow head gaskets. Probably the same dumb a$$ who notices his car is running how in traffic so he turns on the ac more since it is making it uncomfortable for him (or her)
The first time my ld9 blew rod 3, my fault 100% every other problem i had was my dealership being cheap when they fixed it.
I love my LD9, and if I was not considering boost, it would propel my car forever. ( just want more aftermarket support aka eco) GM really screwed the pooch in the small car market by not offering more for this engine.

Thanks for the info that we already know.
My old LD9 went 150k before it was sold. I pushed that motor hard too, and NEVER replaced ANYTHING on it EVER. My father bought it new, and then I took over. Never had a bearing issues, or oil pressure issues, or a head gasket. Never had a timing chain problem. And I was young too, so you know i have that @!#$ at near red line almost every day. It had 75 k miles of my dad's hard and fun driving and it had 75k miles of my hard driving.
No wait, there was one little thing I did change... The spark Plugs... Oh yeah, and the air filter. Oh and i think I might have changed the oil too. You know... just once or twice in 150k (I'm kidding here people, relax)
Dude, there's a lot of people out here who have had Zero issues with the LD9, but then there's a lot of people who have had huge issues.
Now I have an eco now, and I will admit, the torque band is a bit smoother and longer, and it does get a bit better MPG's, but I love the LD9. It's my favorite motor of all time.
Isn' t there a newbie section for this crap?
I have now wasted 5 minutes of my life.
you know bypassing the language filter is still breaking the rules...

Wow, ok first off im going to guess you have never owned a LD9, or if you did you don't know how to take care of an engine period. My old sunfire GT had 279kms on the original motor and i drove it like a nail everyday working delivery, but mind you, i did regular maitnence to it.. never once had a problem with these engines. this is my second LD9 and still no problems.
