Can you adjust valve clearance on kia optima 2.0 cdti


Depends on the year and engine. The older engines have hydrolic lifters. The newer engines 06 and up with CVVT have solid lifters so you would have to pull the valve covers and use a feeler gauge to measure clearances and replace the tappets accordingly.

Tikking noise coming from engine


Yes, you're right, those could be the cause. Also, possible it's a collapsed hydraulic valve lifter, if your car has hydraulic operated (from engine oil) valve lifters. At any rate, it sounds like something loose in the valve train-valve lifter with push rod engines; or cam followers {rocker arms) with overhead cam engines that push on the top of valve stems .
Check a repair manual to see if your engine has valves that can be and need adjusting. Engines with valve lifters do not require periodic adjustment for proper valve clearance. Engines with rocker arms do require checking the valve clearance every couple of years or so.

What is the piston to vavle clearance at top dead center on a 1998 chevy s10 2.2L?


The problem with this question is its not revelant to the engine so there is no spec for this . I can give you the closed valve lbs for the springs 78 lbs or open is 228lbs the valve lash is not adjustable it has hydrolic lifters the plunger travelis 0.2177thpush rod length 8.299 inchs. So i can tell you what you want to know but you need to ask me the question differantly .What do you want to know and i'll will tell you

There is a tapping noise in the motor but its not knocking I think its a lifter it hasent lost any power and its really not getting worse I would like to know what the spec is for tighing down the lifter...


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!

Fig. Fig. 3: With the No. 1 piston at TDC, adjust the top set of valves FIRST; with the No. 4 piston at TDC, adjust the bottom set of valves SECOND-Z24i engine

  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
See Figures 4 and 5
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.

Overhead valves making noise like they need ajusting


Valve Lash ADJUSTMENT 1.6L Engines NOTE: Measure valve clearance with the engine cold.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Remove the valve cover.
  3. Set the engine to Top Dead Center (TDC) of the compression stroke for the cylinder to be adjusted.
  4. Check the valve clearance. The valve clearance specifications are as follows:
    • Intake valves: 0.005-0.007 inches (0.13-0.17mm)
    • Exhaust valves: 0.005-0.007 inches (0.13-0.17mm)
  5. After adjustment, tighten the locknuts to 11-14 ft. lbs. (15-19 Nm).
  6. Repeat for each valve to be adjusted.
1.8L, 2.0L and 2.5L Engines The 1.8L, 2.0L and 2.5L engines utilize automatic hydraulic lash adjusters to maintain proper valve lash at all times. Periodic valve lash inspection and adjustment is not necessary or possible. prev.gif next.gif

I have to adjust valve clearance on my ford 110 engine from 1994. year. Can you tell me right clearance of inlet valves and inlet valves


What engine do you have (size)? Valve adjustment is generally a thing of the past after the introduction of hydraulic lifters (no adjustment). In 1994 your engine should have hydraulic lifters and are not adjustable. Is this a high performance engine? New camshaft, lifter, and rocker set that are adjustable?

Lifter knocking on 1999 Nissan Frontier


red: there were two engines used in the1999 frontier.
The VG30 (V-6 )and the KA24DE (4- CYL)
If you have a V-6, there is no adjustment you can make on the valve clearances. They are hydraulic and self adjust. If they are noisy, you might try changing the oil and filter and using an oil additive designed for addressing high mileage motors with noisy lifters. Marvel Mystery oil actually works, but follow the instructions. MORE IS NOT BETTER!
The 4 Cly engine does not have adjustable valve clearances from the stand point of using a few wrenches, one to adjust and the other to lock the adjuster when the clearance is correct.
These valve clearances are set using shims which are "metal discs about the size of a quarter. They come in various thicknesses and based on the measurement between the base of the cam when the highest point of the lobe is facing the 12:00 position, you place a feeler gauge between the base of the cam and the top of the shim.
If it is too loose or too tight, you use your feeler gauges to find out what it would take to make a zero clearance situation. From there, you remove the shim, measure it. Based on your findings during your initial measurements, you can calculate whether you need to use a thicker or thinner shim.
So to answer your question: unless you have a lifter confused with some other component, there is no means of torquing a lifter down on either series engine which came in that truck.
Please let me know if I can help you further. There must be some reason why you have asked this question......?
