SOURCE: valve clearance check

the only time i would worry about getting the clearance on the valves checked is if the bike starts acting up there is no need to break the gasket seal just to check something that is probably alright anyway

I just did the valve clearance on the engine of my SJ413 that has the 1000cc engine of an SJ410 :
When cold: 0.13mm Intake and 0.18mm Exhaust
Engine sounded well and worked fine after that.

Hey there I need the exhaust and Intake(valve) clearance for a komatsu 300-6 please


note Perform the valve clearance check and adjustment at the engine cold state. 1.Remove all of the ignition coils. 2.Remove the cylinder head cover.
caution Turn the crankshaft always clockwise. 3.Turn the crankshaft clockwise, and align the timing mark on the exhaust camshaft sprocket against the upper face of the cylinder head as shown in Figure. Therefore, No.1 cylinder goes to the compression top dead center. 4.Using a thickness gauge, measure the valve clearance with the arrow shown in Figure. If deviated from the standard value, make note for the valve clearance.
Standard value:

    Intake valve 0.20 ± 0.03 mm (0.008 ± 0.0012 inch)
    Exhaust valve 0.30 ± 0.03 mm (0.012 ± 0.0012 inch)
5.Turn the crankshaft clockwise 360 degrees, and put the timing mark on the exhaust camshaft sprocket in position shown in Figure. Therefore, No. 4 cylinder goes to the compression top dead center. 6.Check the valve clearance with the arrow shown in Figure. In the same procedure as 4.
7.If the valve clearance is deviated from the standard value, remove the camshaft and the valve tappet. For the camshaft removal, refer to Camshaft Removal and Installation . 8.Using a micrometer, measure the thickness of the removed valve tappet. 9.Calculate the thickness of the newly installed valve tappet through the following equation.
A: thickness of newly installed valve tappet
B: thickness of removed valve tappet
C: measured valve clearance
Equation

    Intake valve: A = B + [C - 0.20 mm (0.008 inch)]
    Exhaust valve: A = B + [C - 0.30 mm (0.012 inch)] note The valve tappet ranges 3,000 - 3,690 mm (0.1181 - 0.1453 inch) and has 47 types per 0.015 mm (0.0006 inch). The thickness below a decimal point is stamped on the reverse side of the valve tappet. 10.Install the valve tappet selected through the procedure 9, and put the camshaft in position. For the camshaft installation, refer to Camshaft Removal and Installation .
    11.After installing the timing chain, measure the valve clearance using the procedure 3 to 6. Confirm the clearance is within the standard value.
    caution Completely remove all the old FIPG, which might be remaining among the components. 12.After completely removing the liquid gasket adhering on the timing chain case, cylinder block and cylinder head, degrease them with white gasoline.
    caution The cylinder head cover should be installed within 3 minutes of applying liquid gasket.
13.Apply a 4 mm bead of liquid gasket as illustrated.
Specified sealant:
    THREE BOND 1217G or equivalent
14. Install the cylinder head cover and tighten the tightening bolts using the following procedures.
(1) Temporarily tighten to the following torque in order shown in the illustration.
Tightening torque: 3.0 ± 1.0 N·m (27 ± 8 in-lb)(2) Tighten to the specified torque in order shown in the illustration.
Specified torque: 5.5 ± 0.5 N·m (49 ± 4 in-lb)15.Install the ignition coils.

What is the clearance between the rocker arm and the valve spring in a GM 2.2L motor


there is no specification for what you want
the valve clearance is between the end of the rocker arm and the end if the valve stem
the stem end is proud of the spring retainer so if your rocker arm is touching the spring retainer , you have a big problem as for the procedure it is set out in the workshop manual but if you don't have a manual it can be done like this
you will need the firing order of the engine first
now adjust no 1 piston valves when the next piston to fire has the valves in the rock position
that is the exhaust valve just closing as the inlet is just opening a bit of movement of the crank makes either valve move up or down
adjust no 1 piston valves
now move on to the next piston to fire and adjust the valves that were rocking
follow that procedure until all the valves are adjusted
for example
on a 4 cylinder engine with a firing order of 1--3--4--2
bring up no 1 piston and adjust the valves when the valves on no 3 piston are rocking
next piston to fire is no 4 so adjust no 2 piston valves
next piston to fire is no 2 so adjust the valves when no 1 valves are rocking
the procedure is the same for engines with any number of cylinders

Set valve clearance on 21hp briggs and statton


Valve clearances are set by either tappet screws in the lifters or on a lot of small engines, clearances must be set by either cutting out valve seats with a special cutter tool (to DECREASE clearances) or grinding the end of the valve (to INCREASE clearances) and generally are from .008-.010 on intake valves and .010-.012 on exhaust valves. Check engine specs to insure proper clearances.

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.

I have problem with my engine 4K toyota. It heard an engine noise during idling, for my little knowledge in engine repair, can you give me any procedure mannuals in adjusting engine valves for my...


Valve Clearance Valve clearance is there to allow the valves to cool in between combustion events (spark), and to make sure the valve closes properly and contains the combustion explosion. You need to cool the valves a little bit, the exhaust valve moreso than the inlet, as it's what sees the most heat as spent burnt gases go past it into the exhaust port. Run too little clearance and you'll cause the valve to "weld" a little bit to its' seat every time it closes, and then take seat metal off again when it opens. Do this enough times and you burn out the valve seat and need the head reconditioned. However, by running less clearance, the valve stays open for that little but longer, and you get more air in and out of the motor, and make more power. Run too much clearance and your motor just sounds like a diesel and loses power and tappet rattle annoys you while you're driving, so it's better to err on the side of caution.
The stock valve clearance (0.008" inlet / 0.012" exhaust, warm) is pretty good for any of the cams I've listed above, they're well-sized street cams, not really wild top heavy race cams that require super high compression to work, so don't be afraid to close the valves up a bit from the suggestions of the cam grinder, which will usually say between 0.010" and 0.014". There are a few ways to set your valve clearances:
Yellow Book Method This is from the factory 3K/4K/5K engine manual, aka The Yellow Books. It's the quick and lazy method.
Set engine to #1 TDC. Crank pulley timing mark should be on 0, distributor rotor should be pointing towards spark plug 1 or 2. Set tappets (counting from the front) 1, 2, 3 and 5. Rotate engine 360 degrees, crank pulley to 0 again, distributor rotor turned 180 degrees. Set tappets 4, 6, 7 and 8.
Nine Method I've never really gotten into doing this, takes too much time and maths for my liking :P Rotate the engine through its' range of movement, as one valve is "on the rock" of its' max lift, subtract the valve number from 9 and that's the tappet you should be setting. For example, if #8 valve is open, set clearance on valve #1. If valve #7 is open, set clearance on #2. And so on.
Stewart uses this method, and rotates the camshaft through its entire base circle and sets the clearance at the highest point. Which is a pretty good idea, as it compensates for the possibility that the base circle has been ground unevenly, and allows you to run the proper valve clearance that you want to run, instead of something that may be a few thou larger in reality.

No compression on #4 cylinder on a 84 Mazda 2.0L Where is the exhaust going? What part do I need to fix it? Thank You!


If there is a COMPRESSiON leak in ur cylinder, either ur intake valve or exhaust valve is open during compression! First check ur gap settings of push rod or valve CLEARANCE using FEELER GAUGE. Check also ur BLOW BACK gas by opening ur OiL CAP, and run the engine, too much air from that oil inlet means ur PiSTON RiNGS are busted. Finally, sometimes SPARK PLUG are LOOSE or threads are gone and gas scapes thru that area! Hope that might help u out!
