Anyone else had lot trouble with Silverado? I have slightly leaking rear seal an oil lines, the latest thing is a regulated sensor on oil pump an 02 sensor bad, luckily I have a extended warranty , suppose to be pay for new oil pump an 02 sensor, a 12 hr shop job, the sensor is integrated on oil pump, it cause check engine lite to go on,

What year?

I had similar issues but older truck
and not 12hr flat rate. Fixed by myself.
Bunch of experienced guys om here.

O2 sensors and oil cooler lines were pretty common on those in the 2000s.

Can't recall doing anything with oil pumps though.

What year and what engine?

Ive drove my 2015 Silveraydo 250000 miles. Ruined a transmission pulling a camper but other than that nothing but preventive maintenance.

If it is 20 years old with 150,000 miles things happen.

the trans cooler lines are not good on those either

but once you replace your
lines both brake and trans
your door handles
your shift clip that connects the shift linkage to the transmission
the fuel lines
and just ignore that the fuel tank vent sellenoid sticks

they run a very very long time.

most of that is rust issues
the door handles are plastic fatigue

also keep the frame oiled up

2014, with 3.7 I believe, 125,000 on it

Yeah,
My buddy has one, has just about 150,000 miles. 2018 I think. In the shop more than it isn’t lately.
