I need to know how to go about the second procedure for valve clearance on my 1.5l mitsubishi lancer. ive started on TDC AND COMPLETED THE FIRST STEP BUT LEADING ON TO THE SECOND STEP IS TROUBLE?????? HELP

The clearance, or gap, of the valves on a 2002 Mitsubishi Lancer OZ Rally is the distance between the valve and the valve seat when the valve is in the closed position. The clearance is typically specified by the manufacturer and is measured in thousandths of an inch.
To determine the valve clearance for your Lancer OZ Rally, you will need to refer to the manufacturer's specifications or service manual for your specific model. The valve clearance may vary depending on the type of engine and the specific application of the vehicle.
It is important to maintain the correct valve clearance on your Lancer OZ Rally to ensure that the engine operates efficiently and effectively. If the valve clearance is not within the specified range, it may cause problems such as reduced engine performance, increased fuel consumption, and increased emissions.
To adjust the valve clearance, you will need to remove the valve cover and use a feeler gauge to measure the gap between the valve and the valve seat. If the gap is not within the specified range, you will need to use a wrench to adjust the clearance by turning the adjustment screw on the rocker's arm. It is recommended that you have the valve clearance adjusted by a qualified mechanic if you are not familiar with this process.

There is a specific procedure for setting valve clearance . I highly recommend getting a repair manual for the correct specs & procedure. The engine must be at TDC with the #1 cylinder on the compression stroke , that will allow you to adjust ONLY certain valves , then you have to turn the engine one turn to TDC again only now #1 will be on the exhaust stroke & the rest of the valves can be adjusted . it's important that you know the difference between the two !

Valve clearance Intake 0.20 mm (Hot- at operating temp)
Valve clearance Exhaust 0.25 mm (Hot).

Sounds like timing may be off. Recheck your procedure. Did you change the timing belt?

I would start by putting crankshaft to the zero point on scale-TDC on the compression stroke. Crankshaft will be at zero, TDC, twice; on the compression stroke and on the exhaust stroke. To find the compression stroke, pull the spark plug on number 1, with finger over hole, turn crank by socket until you feel pressure against your finger. Now turn the crank (clockwise) until it is at the zero mark-TDC of compression stroke. Pull off the distributor cap-rotor should be pointing at number 1 plug wire tower-Is it?
If good so far, look for inspection rubber plug to check camshaft timing mark on cam sprocket, OR pull the valve cover off and check the number 1 cylinder camshaft lobes that open the valves-both lobes, intake and exhaust, should be away from the valves. Valves should both be closed on number 1.
Post back with what you find. Good luck.

Take the rocker cover and the upper timing belt cover off.
Set No 1 Cylinder to TDC - use the markings on the cam spocket to get this - and confirm it's on the compression stroke by check both inlet and exhaust valves are closed and on the heel of the cam.
In this position, check rockers 1,2,4 and 5.
Take care with the feeler guage to make sure you're right under the pad under the adjuster screw properly and completely passing under it, not sticking part way.
Rotate the engine (crank shaft) 360 degrees. This should bring No 4 to TDC - confirm that both inlet and exhaust valves are closed and on the heel of the cam.
In this position, check rockers 3,6,7 and 8.

Clearance for Intake and Exhaust is 0.25mm at normal engine operating temp.

Don't forget to fit a new rocker cover gasket and half moon seal (use something like Hylomar to help make sure the half moon is sealed properly - usual suspect when rocker cover leaks at the back of the engine).

The valves for any given cylinder will be closed when that particular cylinder is at TDC and on the "firing" cycle. Since 4 cycle engines have four "cycles" the piston can be at TDC twice. Once for firing and once when the exhaust cycle is completed and the intake cycle is starting.

Cycle 1: Intake valve is open and piston is travelling DOWN. (Intake)
Cycle 2: Both valves are closed and the piston is travelling UP (compression)
Cycle 3: Fuel has been ignited and the piston is travelling DOWN ( power)
Cycle 4: Exhaust valve is open and the piston is travelling UP (exhaust)

TDC is Top Dead Center, or the point that the piston is at the top of it's travel.

Depends on which engine you have. If you have

ADJUSTMENT Although it is sometimes possible to reuse an old cylinder head cover gasket, in most cases it makes more sense to purchase a new one before beginning the procedure. Some vehicles may require the use of silicone sealant either with or without a new cover gasket. For more details, please refer to the cylinder head cover procedures in Engine & Engine Overhaul of this repair guide and refer to the gasket manufacturer's instructions.

Z24i Engine
See Figures 1, 2 and 3
For the intake valves: 1-4-5-8 valve clearance is 0.012 in. (0.30mm). For the exhaust valves: 2-3-6-7 valve clearance is 0.012 in. (0.30mm). The pivot locknut torque specification is 12-16 ft. lbs. (16-22 Nm).

1. The valves must be adjusted with the engine warm, so start the truck and run the engine until the needle on the temperature gauge reaches the middle setting. After the engine is warm, shut it off.
2. Note the location of any wires and hoses which may interfere with cylinder head cover removal, disconnect them and move them to one side. Remove the bolts holding the cylinder head cover in place and remove the cover. Remember, the engine will be hot, so be careful!

1. Rotate the crankshaft until the timing marks indicate that the No. 1 piston is at TDC of the compression stroke. If you're not sure of which stroke you're on, remove the No. 1 spark plug and hold your thumb over the hole. Pressure will be felt as the piston starts up on the compression stroke.
2. Refer to the accompanying illustration (upper part), then check valves (1), (2), (4) and (6) using a flat bladed feeler gauge. The feeler gauge should pass between the valve stem end and the rocker arm screw with a very slight drag. Insert the feeler gauge straight, not at an angle.
3. If the clearance is not within the specified value, loosen the rocker arm lock nut and turn the rocker arm screw to obtain the proper clearance. After correct clearance is obtained, tighten the locknut.
4. Rotate the crankshaft until the timing marks indicate that the No. 4 piston is at TDC of the compression stroke. If you're not sure of which stroke you're on, remove the No. 4 spark plug and hold your thumb over the hole. Pressure will be felt as the piston starts up on the compression stroke.
5. See the illustration (lower part), then check valves (3), (5), (7) and (8). Check and adjust valve clearance as necessary.
6. Install the cylinder head cover gasket, the cover itself and any wires or hoses which were removed. Check the engine oil level.

KA24E, VG30i and VG30E Engines

These models utilize hydraulic valve lifters. Periodic adjustment is neither necessary or possible. There is however a bleed down procedure that is necessary when the valve train has been disassembled.
HYDRAULIC LIFTER BLEED DOWN

1. Remove the cylinder head cover.
2. Check the lifters for proper operation by pushing hard on each lifter with fingertip pressure.
3. If the valve lifter moves more than 0.04 in. (1mm), air may be inside it. Make sure the rocker arm is not on the cam lobe when making this check.
4. Install the cylinder head cover.
5. If there was air in the lifters, bleed the air by running the engine at 1000 rpm for 10 minutes.
