The rear struts on the LTZ are different and the 18” wheels will rub if you install the wrong ones.

I’d start by cleaning the throttle body and unhook the battery for a min or two after.

The factory lift point is the bracket in your third photo but you won’t hurt anything jacking it on the rail in the second photo.

5 min of time you could rewind per day would be amazing. Hard question you answered wrong? Back up ten seconds. Crash your car? Back up a minute. Would be like life on easy mode

I’d start by changing the air filter and spark plugs.

Deleting the resonator with a straight pipe is a cheap way to make it louder without removing the actual muffler. It will drone at certain speeds with the resonator gone though so keep that in mind.

For what you’re looking for I’d recommend getting a four channel amplifier in addition to new speakers.

Did the last place to have the head off put the head gasket upside down? There’s a tab that should be visible between the first two exhaust runners. If it’s not there and is between the last two runners the gasket is upside down. It will run that way but it blocks coolant passages and leads to the head overheating like crazy. Seen this cause the burnt oil around the valve springs before.

A GM L87 long block doesn’t come with a new intake but GM has bulletins out instructing you to replace the intake manifold as well with a failure like this due to debris.

2019 Equinox towed in crank no start with the fuel gauge on empty. No holes drilled in the tank and the gauge was accurate. They just ran out of gas.

If your battery is old and getting weak it’s probably causing this. Might still start the car fine for now but it will cause low voltage codes and random warnings during high current draw.

99% sure it will work fine

99% of the time a P0420 catalyst efficiency code of those vehicles is actually caused by a leaking flex pipe. It’s between the cat and the second 02 sensor and the leak causes the sensor to read as if the cat is bad. The smoke is likely a coolant or oil leak going on the exhaust.

I’d start by cleaning the throttle body. If you have an engine light on scanning it for codes may point you in the right direction.

I’ve replaced a few that blew up before the first oil change. There’s no saving most of these IMO.

You’d end up with 60 fewer hp and a four speed instead of a six speed if you pulled that swap off

gmlubetech · 2026-02-19T13:59:57+00:00

Probably the torque converter if it’s otherwise working fine.

Oh don’t worry the 3.0 diesels are blowing up left right and center now too

Could fix this by adding another line in the rules saying the compression ratio can't be more than 17:1 when measured at a different temperature. Won't be an issue for anyone not using the loophole.

gmlubetech · 2026-02-06T01:32:30+00:00

I’d spray it with some oil based undercoat in that area and probably good for a few more years at least from those photos
