What is the clearance between the rocker arm and the valve spring in a GM 2.2L motor


there is no specification for what you want
the valve clearance is between the end of the rocker arm and the end if the valve stem
the stem end is proud of the spring retainer so if your rocker arm is touching the spring retainer , you have a big problem as for the procedure it is set out in the workshop manual but if you don't have a manual it can be done like this
you will need the firing order of the engine first
now adjust no 1 piston valves when the next piston to fire has the valves in the rock position
that is the exhaust valve just closing as the inlet is just opening a bit of movement of the crank makes either valve move up or down
adjust no 1 piston valves
now move on to the next piston to fire and adjust the valves that were rocking
follow that procedure until all the valves are adjusted
for example
on a 4 cylinder engine with a firing order of 1--3--4--2
bring up no 1 piston and adjust the valves when the valves on no 3 piston are rocking
next piston to fire is no 4 so adjust no 2 piston valves
next piston to fire is no 2 so adjust the valves when no 1 valves are rocking
the procedure is the same for engines with any number of cylinders

How do I adjust valve lash on a 2001 pontiac montana 3400 enging


The lifters are hydraulic, so adjusting them is not possible. The lifters can take up very little play, so valve ticking when cold is normal. I have had two of these engines. Be sure to have the heads torqued properly, to keep play at a minimum.

Can you adjust the TPS on a 2001 Corolla? If yes how do you adjust it?


The best way to adjust the TP position sensor is by a scan tool. With the accelerator pedal fully released the value should be between 9.8% - 18%.

you can pull the valve covers and inspect the rocker arms, but you may have a bad main or rod bearing. im leaning toward the main bearing being spun, at least.
