![]() I brought this auto because I felt compelled to buy an American company automobile, but needless to say I should have bought Hyundai or Kia that have a better/longer warranty. It is now beyond the extended warranty I had purchased when vehicle was purchased new. Only recently I have become aware of ALL THE ENGINE PROBLEMS associated with Chevy 2.4 engines. Even at only 77,000 miles, probable cost is in range of 2650.00 including tax. Engine is very noisy, and I have been advised that probable cause is a TIMING CHAIN ISSUE. I took vehicle to my Chevy dealer who advised me not to drive it as it might incur severe engine damage. I have had recent issues with service engine alerts. I purchased this vehicle new in 2013, and I have always changed oil & filter even more frequently than required by Chevy. Can’t remember what it was quoted at previously. ![]() Someone will chime in with the “Book Number” for this job. and they’d kill you more on the parts, too., And if your Independent rate is $100/hour, and the parts are $400, that’s $1200.ĭealership rate would probably be more like $130/hour, I’m guessing. you should be able to replace a timing chain on one of these engines in an 8-hour workday. to me - if you call yourself a “professional mechanic”, and you therefore have a hydraulic lift and all your tools right there “at the ready”, AND you’ve presumably done at least one of these jobs previously (so you have some experience, which greatly speeds things up). So my experience says “they last forever - as long as they aren’t starved of lubrication” - which is what ends up happening with some of those 2.4L Equinox/Terrain engines.Īs far as replacement cost, I think I’ve seen Independent quotes of around $1200-$1500. Replace your timing chain before it fails!! IT WILL FAIL.Ĭlick to expand.I’ve driven the last three vehicles I’ve bought new well over 222,222 miles and never changed the timing chains on any of them. A complete engine vs cylinder head repair. Sorry to ramble, but this can be a big difference in repair. 3 weeks of misery and the light bulb went on. I ordered new cams and upon installing them I saw clearly the difference in key way locations. I assumed the snouts were all part of the machined cam. So I started tearing apart the original head to find NOTHING wrong. That eliminated the short block as cause. I finally tried a head from a known good vehicle and had compression. I blamed the machine shop for possible putting wrong cam back on my head. I reset timing chain 3 times (like a fool hoping for different outcome). I was ready for this situation from experiencing it once before. I have not seen an exhaust camshaft suffer this fate. So if your shop is going to rebuild your head to repair, might want to provide them with a new intake camshaft. Luckily, in both cases the snout had moved in a way that simply caused intake and exhaust valves to be open simultaneously without pistons colliding into them, but no compression. Unless you have a known good cam to compare to, you simply cannot know that the pressed on snout has moved or is still aligned. This is why GM dealerships replace cylinder heads as opposed to repairing (in my opinion). Machine shops assume cams are good if all the lobes are free of scoring and the snout is free of damage. However prior to altering timing it spun the snout on the intake camshaft by several degrees. Each guide snapped into 2 pieces “jamming” the chain in a way that skipped timing. Both engines had broken front timing guides (cam to crank timing chain). I also asked for all broken/damaged parts from each repair to be sent along. I asked for vehicles to be towed to me for an estimate. I was contacted by one owner and by one shop manager to inquire about a rebuild. Shops informed owners that possibly block was cracked or piston rings broke and engine would need to come out. Timing sets were removed and re-installed to no change in result. Upon re-installation of head and new timing sets the engines still had no compression. Cylinder heads were removed and sent out to 2 different machine shops for reconditioning. ![]() Diagnosis was that engine timing system failed and jumped causing bent valves. Vehicles towed in with a no start complaint. Last week I had two vehicles dropped off to me from other shops here in Vegas that could not get them running again. I work out of my garage as a hobby and second income. I offer tune-ups, SMOG repair, timing chain replacement, and full engine rebuilds. I have an ad on Craigslist that offers my services on Ecotec engines. I wanted to offer up some advice to Equinox and Terrain owners with the 2.4 engine. ![]()
