No. You can remove the engine and leave the transmission in the vehicle.
The plugs run down the center of the engine under the coils. You can see the coils after you remove the resonator (Thing that says Vortec 4200)
You have to remove the engine cylinder heads to get to the lifters on the 5.3.
USE special wrenches.
Begin by removing the engine wiring harnesses. Remove the motor mount retaining bolts. Disconnect the engine from the transmission. Lift the engine out.
how to remove the starter from a 92 s-10 4x2 with a 2.8 engine
The knock 1 sensor on a Vortec 4.8 is located on the top of the engine. You will have to remove the intake to gain access to replace it.
With great difficulty.
On my 93 it is right after the pipes meet from the left and right heads, it is pointed up toward the floorboard. Warm the pipe up a little to make it easier to remove by running the engine for a couple of minutes prior to removing the sensor.
