On 5-25-2013 Chevy started putting better quality engines with improved piston rings in cars. That is how "running changes" are done and tracked. It is the day the car is made.
Yes, engines are built in advance and existing inventory is purged, but 5-25 is the change over date...
Obviously, the new rings made no difference, as explained by several folks on this website have had the same failures again, even with new rings
Do Not tell them, you were low on oil, don't volunteer the info.
Just describe the noise...
You know that gdi equinox's burn oil,
That is why you keep a quart of penzoil platinum in your equinox at all times...
Along with paper towels, so you can check oil levels
Look ( point it out) its penzoil platinum
And you have your notebook.
You now hear noises, and you have the $3000 gm warrentee
bring it to the dealer....
And let the dealer figure it out....
(You know you need new solenoids timing chain and guides, pistons and rings.....)------play dumb!
" but when I pulled the oil cap off with it running tonight I got pressure blowing out of the crankcase,"
That ^^ is probably because...
1. You have major piston blowby, worn piston rings, and scoured cylinder walls.
2. your dirty side PCV orifice which is internal to your engine, is not able to evacuate the blowby crankcase gases fast enough. The dirty side PCV orifice, probably has engine oil sludge and crankcase vapor gunk plugging up (or partially plugged up) the 2 mm in diameter by 6.35 mm in length orifice "hole" , which is molded into the nylon 6/6 intake manifold.
3. your cleanside PCV breather hose which theoretically brings fresh air from air box (after air filter and before throttle body) into crankcase,
is actually trying to vent crankcase pressure, crankcase air is flowing the wrong way (out of crankcase) all the time, (instead of only during wide open throttle))
and this cleanside PCV breather hose is filling up with crankcase gunk, further reducing the crankcase's ability to vent the high crankcase pressure
A solution to all that ^^^ is the the $80 cfm one way vented, with 1 inch nylon ball, it will also prevent crankshaft rear main seal failure,
and then "never mind" the plugged dirtyside PCV orifice. The cleanside breather hose is easily cleaned.
that ^^^ is after you get your engine fixed.
Plugged dirty side PCV
IS NOT ROOT CAUSE of engine oil consumption
(In link above, on page 4 , you can see a picture of a 1/16 inch diameter drill bit inside the dirty PCV orifice
And...... cleanside hose (( top of page 3, #1 in link above)
Root cause is GDI engines, which eventually will consume oil when carbon deposits (like lava rock) that accumulates on intake valves falls of into combustion chamber, .... resulting in oil consumption.....
then unknowingly folks drive cars even though their engines have low oil, and everything in the timing chain system is at risk of failure and then engine is at risk of failure.
Gm always says "your vin number is not covered"
Not your problem you have the warantee
My 2 cents ^^^^
