WHAT IS THE TAPPET CLEARANCE FOR NISSAN GA 15 CARBURATED,INTAKE AND EXHAUST?

The valve tappet clearance for the Mazda Bongo Brawny can vary depending on the specific engine model and year. Here are some general specifications for the different engine types: 2.0L FE engine: Intake valve clearance - 0.18-0.22mm, Exhaust valve clearance - 0.28-0.32mm 2.5L WL engine: Intake valve clearance - 0.20-0.25mm, Exhaust valve clearance - 0.30-0.35mm 2.5L RF engine: Intake valve clearance - 0.20-0.25mm, Exhaust valve clearance - 0.30-0.35mm It's important to note that the valve tappet clearance should be checked and adjusted by a qualified mechanic using the correct specifications and tools. Incorrect adjustment can cause engine damage and poor performance.

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.

Try setting the valve clearance on your 1999 2.7 Nissan Hardboy diesel to 0.14 inches on the intake and exhaust sides.

The tappet clearance for your Hyundai Atos 2007 would be:
• Valve clearance Warm: 0.2 mm intake, 0.25 mm exhaust.
• Valve clearance Cold: 0.1 mm intake, 0.17 mm exhaust.

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

If you have adjustable tappets bring the engine to top dead center no 1 piston firing The rocker will be on the back of the cam lobes. Inlet .010" hot exhaust .012" hot and then turn until next firing piston is in position. Go by firing order. I suspect that a 1997 model would have hydraulic adjusted tappets which means no manual adjustment. If it is rattlly I would be checking for worn rocker shaft and rocker bushes.

The intake should have a .070 clearance and .080 clearance for the exhaust. -------------------------------------------------------------

make sure engine is warmed up. Put cylinder one at top dead center,remove the valve cover,loosen all adjustment lock nuts,adust intake and exhaust valves on cyl #1 and intake valve on #2 and exhaust valve on #3. now rotate crankshaft 360 degrees clockwise, now adjust intake valves on cyl#3 and cyl #4 and exhaust valves on cyl #2 and cyl #4.now tighten lock nuts and install valve cover. specs are intake valves 25mm clearance and exhaust 28mm clearance, use a feeler gauge,heres a picture to show you where to check clearance.

forget book set intake at 10 exhaust same use 20/50 oil hey vote for me ok

On the intake 0.0008 or 0.0020 (it's in between these 2)

this is for the stem to guide clearance. (for the intake)

The Exhaust 0.0018 to 0.0030 stem to guide clearance.
