Intake and exhaust valve clearances? - 1991 Nissan Pickup

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 when the engine is completely cold.

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).

make the engine runs for about 30minutes before adjusting the valves,
valve clearances:
intake valve = 0.20mm(0.008 in)
exhaust valve = 0.25mm(0.010 in)
for reference only when the engine is cold,
valve clearances:
intake valve = 0.25mm(0.010 in)
exhaust valve = 0.30mm(0.012 in)
engine specs: mitsubishi 4g13 1.3L (if you have same engine)

the valve clearance is intake .006 exhust .010 they must be set with engine cold passenger side is the intake driver side is the exhust send me your e-mail and i will send you the procedure.

This is the specs for the 4H Diesel engine:
Intake valves clearance cold 0.4mm(.016inches)
Exhaust valve clearance cold 0.4mm(.016inches)

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.

valve clearance, with engine hot, intake valves are .005-.006 in, exhaust valves are .011 in, if engine is cold then its intake .009-.011 in and exhaust is .007. hope this helps good luck.
