What are the intake and exhaust valve tappet clearance specs. of a honda civic 1999 1.6 liter vtec sohc engine?

large trucks.
D4xx diesels engines used x4 some turbo and not.
its 4 engines not 1, and maker has an EM# engine manual on each

16valves, 4cylindes. SOHC about 4Liters

6.5KG ,MGVW
SO BUY the service manual
or google D4 specs?
i read you D4, service book and it has no such thing at ALL
it uses HLA tappets. hydraulic lash adjusters
so let may guess they make noise and is why the hunt started.
end another fake hunt to nowhere.

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.

valve clearances sohc 4g63 carb motor both hot and cold

Valve clearance - INLET mm: 0,15 hot
Valve clearance - EXHAUST mm: 0,25 hot
This engine is set hot if you are repairing the engine and have to do this cold
then set to 0.10mm INLET and 0.20mm EXHAUST
Then once hot readjust to specs

- 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.

Intake: 0.007-0.009 in. (0.18-0.22mm) Exhaust: 0.009-0.011 in. (0.23-0.27mm)

Valve clearance with the cylinder head temperature less than 100 degrees Fahrenheit, is as follows:
Intake .007 - .009 inches
Exhaust .009 - .011 inches

The 96-98 Civic EX came with an OBD2A D16Y8 engine. That is the only engine that will go in as a direct replacement with your current engine ECU. It's an SOHC VTEC engine that has two extra connections not found on the other 96-98 Civic engines - a VTEC solenoid and a special oil sensor used to determine if VTEC engagement is possible. If you swap in an older Civic engine (92-95 generation) you'll have to convert the car to OBD1 (requires a special adapter hardness) and run the ECU that goes with whatever engine you use. This will break functionality of your OBD2 diagnostics port, and depending on which state you live in will cause you to fail emissions checks. If you install a D16Y8 engine from a 99-00 Civic EX, you will have to swap the intake and exhaust manifolds from your old engine to the new engine, and you will be able to continue to run your existing OBD2A wiring and ECU. The 99-00 Civic EX engines have additional sensors, since those engines are OBD2B. The easiest fix would be to find a SOHC VTEC D16Y8 from a 96-98 Civic EX, as it would be a direct plug and play replacement.

7k clearances are ( HOT ) Inlet 0.008 in ( 0.20 mm )
Exhaust 0.012 in ( 0.30mm)

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.

Intake valve clearance 0.15mm-0.19mm (6-7 thou); Exhaust clearance 0.17mm-0.21mm (7-8 thou). All measurments COLD engine. 2.2 VTEC Prelude engine 1992-1996, import and UK.
