Adjusting tappet clearance

The valve clearance specification for a 1998 Hyundai H100 2.6 diesel bakkie is:
Intake valve clearance: 0.25 - 0.35 mm (0.010 - 0.014 in) Exhaust valve clearance: 0.45 - 0.55 mm (0.018 - 0.022 in)
The tappet setting for this engine will depend on the specific valve clearance measurements for each valve. If the valve clearances are found to be outside of the specification, the tappet settings will need to be adjusted accordingly. It is recommended to refer to the manufacturer's service manual for detailed instructions on how to perform the adjustment procedure.

What year is the vehicle? Most modern cars often don't need the valve clearances adjusted. They are fitted with Hydraulic 'Tappets' that automatically adjust to suit the valve clearances as the engine warms up. You can usually tell by looking at the valve rockers. Hydraulic set ups don't have adjustment screws fitted to the ends of the rocker.

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.

Adjust intake valves to .008" (.20mm) and exhaust valves to .010" (.25mm) for the R16 engine. For the R17 engine the clearance is the same with the exception for the Gordini engine. On that one you adjust the exhaust valve to .012" (.30mm) https://www.6ya.com/callphilipforhelp

The Chilton and Haynes manuals are your best bet. Order it at your local Autozone or goto the Library and research them online fro free.

Valve clearance specification when cold :
59 to 77deg F or 15 to 25deg C (engine temps)
Intake: 0.0063 to 0.0094 inch (0.16 to 0.24mm)
Exhaust: 0.0123to 0.0153 inch (0.31to 0.39mm)
you must remove the bucket,tappet , to change lash.
MIKE IT (that means a micrometer)
then buy shims or new buckets to fit. (generic answer)
the book says buy correct tappet after measuring, yours.
and it's out of range, and doing the math first.

that is it.

- 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.

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.

According to http://freespace.virgin.net/tommy.sandham/databook.htm# Rocker Adjustment, the cold clearance is .008" intake/.018" exhaust in the non-GT 1500cc, and .012" intake/.022 exhaust on the GT. Sweet little car!!!
