try installing a new PCV valve and were the valve seals ever replaced?
Just as long as you get the proper length plugs for the engine you won't damage anything.
they are on both sides of the engine just under the spark plug wires.
The spark plugs are located right under the exhaust manifolds of both sides of the engine. You should just follow the spark plugs wire from the distributer.
The spark plugs in the 3.8L V6 are located directly below the valve covers on each side of the engine. They are very difficult to get to in the Camaro, because the engine sits so far back in the engine bay. Follow the wires to find the plugs. (3 per side) Look for the six flexible wires going from the tom of the engine to the sides. There should be three a side going from the common point (the distributor cap) to three spark plugs on each side. i have a 99 camaro and i just changed plugs. To change them you have to get under the car and they are about middle way on the block. they are a pain to get too and you will need a swivel socket to get to most of them. There is only 1 you can get too from the top of the car. make sure you let you car cool down. 2 plugs are right by the exhaust manifold.
i would check the freeze plugs on both sides of the side of the engine block.
.060 is the specified gap setting on spark plugs for a 2000 camaro rs.
0.35
There are two, both on the backside of engine near flywheel. Can be accessed by removing engine or dropping tranny. I know, I just left the shop for the same reason.
.054
3 of the plugs are on top of the mottor and 3 of them are on the bottom side
