what engine is there exactly?, (step 1 to work any engine is. this.
gas/petrol of diesel? engine size. like, 3.0L? V6?
wiki
The 1400 Bakkie was assembled by Nissan in Rosslyn, South Africa (Nissan)

1.4L engine a very small pickup truck and tiny obscure engine
that wiki fails to identify.
buy the manual for NISSAN.
it is not a diesel ,and this list is all 1.4L listed by maker,1.4L and in year range.
GA14DE DOHC, 2 CAMS? AND ROCKERS? 12VVALVES
The GA14DE does not have hydraulic lifters, so special shims are used to adjust the valve clearance.

CGA3DE DOHC, 1,4K Sold as but is 1.348L
data super hard to source on the engine.
one photo shows head cams over valve stems, no tappets at all
see photo, I see bucket lifter there, so are shims.

CR14DE, with vvt

The Nissan CR14DE motor does not have hydraulic lifters, so special valve lifters are used to adjust the valve clearance.

so knowing this engine fact and the exact one makes this more easy

lacking manual or engine name, i'd look first.

CDA3DE, FOR SALE, SEE THE BUCKETS , I DO.

Not all modern engines need you to set the valve clearances. Most engines use oil filled 'tappets' that self adjust the clearance as the oil temperature changes. Depending on which engine it is yours has a lot of the time you can only check the valve clearance but not adjust it.

Valve lash is the end of the rocker arm and the valve stem clearance between. When the engine is running, due to the thermal expansion and contraction, if there is no gap between the rocker arm and the valve stem, rocker arm swells, the top valve open, the impact of engine power and economy. Engine valve clearance will be different, usually when the car is cold, the intake valve 0.08-0.10MM, clearance exhaust valves 0.10-0.12MM Car Diagnostic Tool

Does anybody know what is the valve clearance for inlet and outlet for this type of engine? ... Nissan Xterra Forum · Nissan Armada Forum · Nissan Frontier Forum ·Nissan Titan Forum ..... the head so they don't burn up, especially the exhaust valves.Tight exhaust valves are the #1 reason they burn up.

12 inlet and 15 exhaust is used on most engines unless its a old 60s GT model

What is valve clearance of Nissan TD 25

When it is stated that valve clearance should be set when hot, you first adjust the clearance on the cold engine after assembly to the hot setting specs if they are the only ones given, then let the vehicle warm up to operating temperature. Then adjust the clearances again.
If it is just a tune-up(undisturbed engine), let the engine warm up to operating temperature, then adjust.
The reason is that metal expands as it heats up, which affects the valve clearance.

First off you need to disconnect the battery. then you will need to take the plug wires off be sure to number them per cylinder. NOTE on the passenger side you have cylinder starting from the front of the engine 1-2-3 3 being at the back of the engine. on drivers side you have 4-5-6 6 being at the back of the engine. firing order is clockwise- 1-4-2-5-3-6.. then you will have vacuum lines that have to come off so you would need to mark those as well as to where they go, you can use masking tape and a fine point black marker. You must take out the altenator for better clearance on the passenger side and you may have to loosen the distributor to have clearance because of the ignition module if it is in the way. most hoses and fuel lines can be lifted up with a bungie cord and connected to the hood for getting those out of the way. the biggest pain is the wiring harness for the engine that runs through the pentium you can wiggle it enough to bungie it up out of the way. you may also find that you have to remove the heater hoses also since that will give you more clearance on the passenger side. the bolts are a 10 mm they also should have a spreader on them that you must look for under the bolt very important to put these back on. carefully lift and remove the vavle covers. clean all gasket and material off of the engine and on the vavle covers you want them clean enough to eat off of.. check vavle covers where the bolts attach to see if the vavle cover is straight if not then use a board under the vavle cover lip to tap the holes back down from the underneath side to get them straight. once all this is done then you need to get i suggest the cork felpro gaskets and some black sealant for valve covers. once the vavle covers are clean and ready for install then coat the valve cover where the gasket goes with sealant and let it setup- very important. then coat the gasket on one side and put it on the valve cover the valve covers have cutouts to where the tabs on the gaskests go then install on the valve cover. then coat the gasket again and let it setup for awhile very important. then reinstall the valve covers using a criscross pattern staring from the center out then tighten all bolts the same . very important do not over tighten the bolts just snug them up otherwise it will leak-reason the valve covers will warp by the holes.. and let the vehicle sit for about 12 hrs to make sure the silicone is set up.. it is a good weekend project did my fathers took about 2 days sat-sun but never leaked since..

i do not know but give these websites a try www.alldatadiy.com and www.autozone.com if all fails stop by your local library and get your hands on a Haynes auto repair manual for your car wish you the best of luck Michigan Man.
