PLEASE HELP!! I have a 2002 Pontiac Grand Am 2.2L & I installed the new timing chain as follows. I installed crank key @ 12'o clock, timing mark on cam at 5 o' clock, inatke cam shaft @ 2 o'clock,

You use the "0" keyway, the others are for modified engines with aftermarket cams.

A new timing chain will not affect ignition timing unless the chain is incorrectly installed then the whole engine is out of time. Why not state what the problem is instead of a generic question like you posted.

My info showed this. Overkill, got an email saying, "can you answer this"? Everybody have a good day.

Hi.

I uploaded the instructions for 2002 Pontiac Grand AM L4-2.2L VIN F engine in the page available at the link below. Before startling please make sure that you have the L4-2.2L engine.

Timing Chain replacement.

Regards.

Ginko.

By :"specs" I assume you need install position? To index the gears, whne you take it apart, turn the crank pulley 'till the timing mark aligns with the "0" on the timing scale. Don't turn the crankshaft again. When you are ready to install the chain, locate the mark on the crank gear and align the mark on the cam gear so they point to each other. The mark on the crank gear should be at 12 o'clock and the cam gear mark at 6 o'clock. Make sure when you put the cam gear on the cam that the location pin fits into the gear to position it correctly. Jeep recommends that after putting the chain and gears on, you rotate the engine by hand and place the crank mark at 6 o'clock and the cam gear at 3 o'clock, then count the number of pins in the chain (pins, not links) between those two points. There should be 15 pins. If you are rebuilding the engine and have the cylinder removed, it's a good time to check the front crank pulley (some have the outer ring move on the rubber). Put a piece of flat steel across #1 cylinder with a bolt through the steel extending into the bore center. Turn the engine by hand 'till the piston contacts the bolt. Make a mark on the pulley and turn the engine in the opposite direction till contact is again made. Your timing mark on the pulley should be exactly between the two marks you made. If not, make a new mark at that point and use that as your actual TDC reference. If it is radically off, replace the pulley.
When setting up cam position I always use a degree wheel. If you are installing an aftermarket cam
its important to do that. If you're just replacing a stock chain, You will be fine with the method I've outlined.

84 should still have points. before you remove the old chain make sure number 1 cylinder is at top-dead-center for firing. Be sure the rotor in the ditributor is pointing at number 1. If you are careful in your instal and dont move anything all will be fine when you are done. If something moves be sure the timing marks and rotor are lined up again before you install chain. Timing marks should be on the crank and cam pulleys and should be lined up. Check a manual for correct alignment

YOU WILL SEE A HOLE IN THE CAM GEAR THAT A 3/8 BOLT WILL FIT INTO. PUT A BOLT INTO THE HOLES OF BOTH CAM GEARS. THEN LINE UP THE CRANK PULLEY KEYWAY AT ABOUT 12 O'CLOCK WITH THE MARK ON THE ENGINE BLOCK.

MAKE SURE TO COMPRESS THE CHAIN TENSIONER AND RELEASE IT WHEN THE CHAIN IS IN POSITION.

Mark are on the crank and cam timing gears. Cam gear mark at 12 o"clock crank gear mark lined up with TGC mark on block when installing timing belt.
