How to replace the lifters in my 04 chevy cavalier 2.2 ecotec with out pulling the head

SOURCE: spark plugs

The spark plugs on the cavalier are under the 2.2 ecotec panel located on the top of the engine. There are no spark plug wires to deal with. The electronic coil pack directly attaches to the plugs with rubber seats like in a spark plug end. Then you use a deep socket ratchet to get the plugs out. Use anti-seize compound when replacing the plugs.

Just the guide is probably making the noise. So either a new guide or a new chain. I would start with guide first, unless chain looks loose or cruddy

You should buy a manual. If someone gave you an incorrect number you could have serious problems.

You usually don't need to pull the heads. I'm not exactly familiar with that engine but 50% of the time you can get a magnet and pull them out through the valve covers. But to make sure it's the lifters. Let it run until it's warm and remove the valve covers. You at that point should push with your finger on the push rod side of the tappet. If one of them ticks (you will be amazed you just did it with your finger) thats the bad one. However the whole cause of the problem with hydraulic lifter is oil pressure. The 0-ring seal between the oil pump screen and the oil pump may be cut, causing aeration of the oil. Thus lowering oil pressure causing the tick. It is normal for some LIGHT ticking to occur in the 4.8L and some noticeably louder ticking on startup. Good luck!
