Hi I have 3 questions. Number one how do you take a crankshaft pulley off without a stap wrench to keep it from turning. Then how do you remove the wheel without a 3 jaw puller. I am trying to get into the timing cover so I can remove everything to inspect the camshaft. I had a lifter go so I need to know how bad it damaged the cam. Question 2 is I have removed all the head bolts and the heads will not come off I tried a screw driver in the intake port and it does not even budge is their a easier way to get them off. I have also hit it hard with a rubber mallet and nothing. Last question is their was no refrigerant in my a/c I know it has a leak somewhere so I am still looking. I am going to replace the seals is their a certain torque rating for these seals. This is all on a 1998 Chevy Camaro. This is a LS1 motor. Thanks.

First thing if you have a bad lifter and it's worn on the bottom the cam is gone so you need another. If you are pulling the head, you don't need to do that for a camshaft but it has tocome off now. The intake and dist will need to come off to pull the head. There are three bolts that hold the pulley an done that hold the crank balancer when the pulley is off the three way puller bolts where the pulley was after the large bolt is out for balancer. If yo don't have an impact for the large bolt hold the fly wheel with a glarge screwdriver inone of the teeth you may need an assistant.

Yeah I am trying to replace the lifters also but I can't get to them unless I take the head off. The heads are stuck. I already took the manifold and intake off. I also removed the pulley and all the bolts and it still won't come off. Is their an easier way to get these off. I want to spray wd40 on it but I am afraid that it may rust the heads. For the A/c is their a special torque that I should use so it doesn't leak. Like I said I am replacing all the A/C seals. Thanks for all the help.

Iwas thinking of wrong engine there is a special puller for the harmonic balancer.
Disconnect negative battery cable. Remove intake manifold, exhaust manifold and valve cover. See procedures in INTAKE MANIFOLD, EXHAUST MANIFOLD and VALVE COVERS.
Remove rocker arms, and pushrods. See ROCKER ARMS & PUSHRODS. Remove vapor vent pipe. See VAPOR VENT PIPE. Remove ground wires and bolts from rear of head. Remove power steering pump pulley using Pump Pulley Remover (J 25034-B). Remove power steering pump mounting bolts.
Remove power steering pump assembly, and set aside. Remove power steering pump mounting bracket bolts and bracket. Remove cylinder head bolts and cylinder head
