This engine is equipped with hydraulic valve lifters. No adjustment is required.Rocker arm bolts (10) to 32 N.m (24 ft. lbs.). The hydraulic lifter should be on base circle of the camshaft. DO NOT OVERTIGHTEN. Hope this helps.

I believe valves in modern vehicles are hydraulic and do not require adjustment. It is possible your vehicle may be different or has been modified. Solid lifters are not unknown just not real popular because of the maintenance they require. If there is a problem with the vehicle and you suspect valves are out of adjustment, you could remove the 4 bolts that hold the cover on and look. If there are adjusters, they will be immediately visable.

.006" both valves
when no3 piston has valve rock adjust no 2 cylinder valves
when no 1 has valve rock adjust no 3 cylinder valves
go google and type in valve clearance of deutz 3 cylinder engine

Tip

Adjustting valve lash


If the firing order is "1-3-4-2". First put it no.1 piston TOP DEAD CENTER. with the marks aligned. Adjust valve lash according to spec on intake and exhaust. Then turn crankshaft on whatever rotation it is suppose to go eg counter clockwise etc. quarter turn ( four cylinder engine). then adjust number 3 ( firing order 1-3-4-2). Then do the same for cylinder 4 and 2.

A ticking sound in the engine when it start heating up...


sounds like hydrualic lifters , if sound goes away when warm then they are wearing , but dont panic sometimes they can be like that for years , if you car does'nt have hydrualic lifters then valve tappets can be making this noise , they may need adjusting.

Valve settings


- Pull the hand brake and put transmission in neutral.
- Remove spark plug cords.
- Remove the spark plugs.
- Remove the Tappet cover
- Lift up the left front wheel.
Cylinder number 1 is toward the pulleys and belts side.
- Rotate the crankshaft anticlockwise with socket and extension rod and bring the valve tappets (intake and exhaust) No. 4 cylinder on dancing position.
NOTE: THERE ARE OTHER WAYS ALSO TO ADJUST THE FOUR VALVES AT A TIME. BUT AS DIY FOLLOW THE FOLLOWING METHOD TO AVOID ANY CONFUSION.
- Adjust the valve clearance of number 1 cylinder.
Valve clearance:
Intake 0.18 - 0.22 (cold) Exhaust 0.25 - 0.28 (cold)
- Rotate the crankshaft anticlockwise to bring the valves of cylinder 2 on dancing position and adjust the valves of No. 3 cylinder.
- Similarly rotate the crankshaft to bring the valves of No. 1 cylinder on dancing position and adjust the valves of No. 4.
- Rotate the crankshaft anticlockwise to bring the valves of cylinder No. 3 on dancing position and adjust the valve clearance of No. 2 cylinder.

You said youknew the torque specs for my rocker arms on the 92 chevy s-10 pickup 2.8 liter v-6


  1. Crank the engine until the mark on the Harmonic Balancer lines up with the "0" mark on the timing tab and the engine in the number one firing position. This may be determined by placing fingers on the number one valve as the mark on the damper comes near the "0" mark on the timing lab. If the rocker arms are not moving, the engine is in the number one firing position. If the rocker arms move as the mark comes up to the timing tab, the engine is in the number four firing position and should be turned over one more time to reach the number one position.
  2. With the engine in the number one firing position as determined above, the following valves may be adjusted:
    1. Exhaust: 1, 2, 3
    • Intake: 1, 5, 6 (Even numbered cylinders are in the left bank; odd numbered cylinders are in the right bank; when viewed from the rear of the engine).
  1. Back out the adjusting nut until lash is felt at the pushrod then turn in the adjusting nut until all lash is removed. This can be determined by rotating the pushrod while turning the adjusting nut (figure 7). When the play has been removed, turn the adjusting nut in one and one-half additional turns (to center the lifter plunger).
  2. Crank the engine one revolution until the timing tab "0" mark and vibration damper mark are again in alignment. This is the number four firing position. The following valves may be adjusted:
    • Exhaust: 4, 5, 6
    • Intake: 2, 3, 4

Can you please give me the tappet settings for a Honda civic 2004 1.6 Vtec please.


Do you mean 1.7L? I do not see a 1.6L in the manual. Instructions from autozone.com are pasted below.

lash:

Intake, 0.007-0.009 in (0.18-0.22mm).

Exhaust, 0.009-0.011 in. (0.23-0.27mm)

Civic
1.7L Engine

NOTE Adjust valves only when the cylinder head temperature is less than 100 degrees F.

  1. Before servicing the vehicle, refer to the precautions in the beginning of this section. Disconnect the negative battery cable.
  2. Note the radio security code and the radio presets.
  3. Remove the ignition coil cover. Remove the ignition coils. Remove the throttle cable clamps and harness holder from the cylinder head cover.
  4. Remove the cylinder head cover retaining bolts. Remove the cylinder head cover from the engine.
  5. Remove the grommet from the upper cover and disconnect the camshaft position (CMO) sensor connector. Remove the upper cover.
  6. Set the number one piston at TDC. The UP mark on the camshaft pulley should be at the top, and the TDC marks on the pulley should line up with the top edge of the cylinder head.
  7. Using the proper gauge feeler gauge, adjust the valves on cylinder number one.
  8. Rotate the crankshaft 180 degrees counterclockwise. The UP mark on the camshaft pulley should be toward the exhaust side of the cylinder head.
  9. Using the proper gauge feeler gauge, adjust the valves on cylinder number three.
  10. Rotate the crankshaft 180 degrees counterclockwise and bring the number four piston to TDC.
  11. Using the proper gauge feeler gauge, adjust the valves on cylinder number four.
  12. Rotate the crankshaft 180 degrees counterclockwise. The UP mark on the camshaft pulley should be toward the intake side of the cylinder head.
  13. Using the proper gauge feeler gauge, adjust the valves on cylinder number two.
  14. Install the cylinder head cover.
  15. As required, reprogram the ECM/PCM engine idle characteristics. Be sure all electrical items are OFF.
  16. Start the engine. Hold the idle speed at 3000 RPM-s in park or neutral until the radiator fan comes on or the temperature reached 194 degrees.
  17. Let the engine idle for about five minutes with the throttle fully closed.
  18. If the radiator fan comes on during the five minutes, do not count this toward the five minute programming time.
  19. Set the clock.

How do you adjust aftermarket roller rocker arms


well first you need to know the firing order...if it's a small block chevy the firing order is 18436572. You need to write the second four digits underneath the first four digits.

so it looks like this 1843
6572

This will let you know which rocker to adjust...turn the engine over by hand using a rachet on the crank shaft bolt by the harmonic balancer until you get both rockers for number 6 cylinder moving at the same time. Now you may adjust the clearance for both rocker for number 1 cylinder. Then crank the engine over by hand again until number 5 cylinder rockers start to move. Now you can adjust the clearance on number 8 cylinder. You will need to know the manufacturer specs for the valve clearance...continue until all rockers have been adjusted.

Note: The engine should be warm when you make the adjustment.

please rate this.
