What is the valve clearance of nissan caravan


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

Torque settingsfor head on lister petter mini6 engine


I have just rebuilt one for our Westerly 21. This is from my Petter 'A' range workshop manual:-
The water cooled engines (AC1W etc.) are:cylinder head nuts: 30NM (22 lbft) except 32.5NM (24 lbft) for the one that also holds the rocker.
Valve clearances are 0.1mm (0.004") COLDReset valve clearance after one hours running since torquing the head.
Retorque head and set valve clearance after initial 20 hours running
I believe Mini-6 refers to the water cooled engines but just in case, the air cooled engines are 27N (20 lbft)

There is a tapping noise in the motor but its not knocking I think its a lifter it hasent lost any power and its really not getting worse I would like to know what the spec is for tighing down the lifter...


Depends on which engine you have. If you have


ADJUSTMENT Although it is sometimes possible to reuse an old cylinder head cover gasket, in most cases it makes more sense to purchase a new one before beginning the procedure. Some vehicles may require the use of silicone sealant either with or without a new cover gasket. For more details, please refer to the cylinder head cover procedures in Engine & Engine Overhaul of this repair guide and refer to the gasket manufacturer's instructions.

Z24i Engine
See Figures 1, 2 and 3
For the intake valves: 1-4-5-8 valve clearance is 0.012 in. (0.30mm). For the exhaust valves: 2-3-6-7 valve clearance is 0.012 in. (0.30mm). The pivot locknut torque specification is 12-16 ft. lbs. (16-22 Nm).

  1. The valves must be adjusted with the engine warm, so start the truck and run the engine until the needle on the temperature gauge reaches the middle setting. After the engine is warm, shut it off.
  2. Note the location of any wires and hoses which may interfere with cylinder head cover removal, disconnect them and move them to one side. Remove the bolts holding the cylinder head cover in place and remove the cover. Remember, the engine will be hot, so be careful!

Fig. Fig. 3: With the No. 1 piston at TDC, adjust the top set of valves FIRST; with the No. 4 piston at TDC, adjust the bottom set of valves SECOND-Z24i engine

  1. Rotate the crankshaft until the timing marks indicate that the No. 1 piston is at TDC of the compression stroke. If you're not sure of which stroke you're on, remove the No. 1 spark plug and hold your thumb over the hole. Pressure will be felt as the piston starts up on the compression stroke.
  2. Refer to the accompanying illustration (upper part), then check valves (1), (2), (4) and (6) using a flat bladed feeler gauge. The feeler gauge should pass between the valve stem end and the rocker arm screw with a very slight drag. Insert the feeler gauge straight, not at an angle.
  3. If the clearance is not within the specified value, loosen the rocker arm lock nut and turn the rocker arm screw to obtain the proper clearance. After correct clearance is obtained, tighten the locknut.
  4. Rotate the crankshaft until the timing marks indicate that the No. 4 piston is at TDC of the compression stroke. If you're not sure of which stroke you're on, remove the No. 4 spark plug and hold your thumb over the hole. Pressure will be felt as the piston starts up on the compression stroke.
  5. See the illustration (lower part), then check valves (3), (5), (7) and (8). Check and adjust valve clearance as necessary.
  6. Install the cylinder head cover gasket, the cover itself and any wires or hoses which were removed. Check the engine oil level.

KA24E, VG30i and VG30E Engines
See Figures 4 and 5
These models utilize hydraulic valve lifters. Periodic adjustment is neither necessary or possible. There is however a bleed down procedure that is necessary when the valve train has been disassembled.
HYDRAULIC LIFTER BLEED DOWN
  1. Remove the cylinder head cover.
  2. Check the lifters for proper operation by pushing hard on each lifter with fingertip pressure.
  3. If the valve lifter moves more than 0.04 in. (1mm), air may be inside it. Make sure the rocker arm is not on the cam lobe when making this check.
  4. Install the cylinder head cover.
  5. If there was air in the lifters, bleed the air by running the engine at 1000 rpm for 10 minutes.

Settings and the valve clearances


Valve Setting is usually done only by authorised service center of Hundai, because if you do the setting wrongly it may hurt the car performance. Kindly go to the car service center or you can get the data only by visiting any Hundai service center directly.

Oil leak from rocker box on 1996jeep cherokee2.5td


Get you a new gasket for the rocker cover, make sure you clean the mating surface good,and all traces of old gasket, and silicon etc. make sure you dont overtighten the bolts to the rocker cover. the torque for the rocker cover is 35 in lbs (4nm). as far as vavle clearance it is none adjustable. A clicking valve can indicate worn lifters, sometimes an oil change will quiet down noisy lifters. If noisy lifters persist you would have to service the heads. If you decide to do that yourself you can ask for a procedure on that too later on. Removal of the head is very difficult, because you need to remove a lot of things, and require you to do a timing on the engine.
