Seems to me we've seen post 2013 model year oil consumption complaints here. GM claimed (in the Class Action Lawsuit for the bad piston rings), that any 2.4L Equinoxes built after May 2013 had the corrective rings already installed. so why cave right now and pony up $5,000 when you may have a condition, though not ideal, that you can live with. But that day might be way off in the future. And then, only if the oil consumption started moving rapidly toward engine destruction would I finally make a decision to either replace the engine or dump the vehicle. Personally, I would just drive it to failure, but I would try hard to avoid that by continually monitoring the oil level, making sure the engine never experienced a low oil condition. Use quality gasket sealer where recommended, and you will have the best results if you allow the sealer to dry overnight before running the engine. When you're installing the new chain and gears, keep in mind that it is possible to turn the engine or a camshaft to the point where a valve may contact a piston, so don't force anything! Also, follow the directions to release the chain tensioner after is is re-installed, and if you haven't done so previously, pull the sparkplugs, and temporarily install the harmonic balancer, and turn the engine by hand to see that you aren't hitting pistons with valves you will notice that it takes several chain revolutions for the timing links to line up again with the marks on the gears, but don't put the covers on until you are satisfied that the timing marks are still all lined up. If the timing chain cover doesn't pry off fairly easily, make sure you have removed all the bolts! There is a bolt in the middle of the cover that is easy to miss. Have a large adjustable wrench to hold the camshafts while removing the sprocket bolts, and for the chain tensioner. (See this post for location of port P0420 - Its not the Cat or 02 sensors ) Prevent the engine from turning counter-clockwise at all times, since the timing chain will skip teeth on the sprockets!īe prepared to reset the timing chain 's fairly simple with a vice and a screwdriver, just don't stab yourself!Ĭlean your PCV port with a small 90 degree pick since you're going to have the valve cover removed. Be careful not to damage female threads in the crankshaft when using either of the pullers ! You may want to replace the Woodruff key (~$7 at a dealer). Use an impact driver to loosen the crank/harmonic balancer pulley.
