I own 95 toyota 4runner. I would like to check.and adjust the valves. Will someone walk me thru the right way of doing this?Thank you.


First of all you will need a decent set of tools. depth feeler gauges, a workshop manual with the valve clearances, and a method of turning the engine by hand. You will need to take off the valve covers. After this you can check each of the valves for clearance by sliding the feeler gauges into the gap between rocker-arm or cam lobe and valve or tappet. Trick is you can only do this when the engine is in the correct position, so consult the manual and rotate the engine by hand accordingly. Remove the spark plugs to make rotating the engine easier. Adjust the tappet to gain the proper clearance as documented in the workshop manual. The feeler gauge should drag just slightly as you slide it out or slide it in. In ideal conditions I would guess this is about a 2~3 hour job, assuming ideal conditions, and not too much stuff in your way that will need to be moved. If your working at home, those are not ideal conditions.

For the record I've only done this sort of job on motorcycles, so I've never actually adjusted tappets. The theory is the same though.

Can you adjust valve clearance on kia optima 2.0 cdti


Depends on the year and engine. The older engines have hydrolic lifters. The newer engines 06 and up with CVVT have solid lifters so you would have to pull the valve covers and use a feeler gauge to measure clearances and replace the tappets accordingly.

Wht is the procedure in making tappet clearance of honda vtec 98


for adjusting the valves look for a sticker under the hood with valve clearance specs or a service manual.You will need appropriate feeler gauges and a 10mm wrench and a flat tip screw driver.If the car is a 4cylinder the cam gear will have 4 notches on it they represent watch cylinder to adjust if it is a six cylinder the front cam will have notches on it with numbers on it you adjust the valves of the cylinder number that is lined up with the timing marks.I recommend using a vernier caliper and setting it to the correct clearance that the valves are supposed to be set to and drag the feeler gauge through it so you can get use to what the correct clearance feels like on the feeler gauge.If you have never done this I would take it to a good shop because this does take some skill and drivability problems can occur if done incorrectly.Good Luck!

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.

How to measure tappet clearance with dial gauge


When setting tappets, it has to be born inind that the valve stem wears an indentation into the face of the rocker. This prevents a really accurate tappet adjustment, so the customer is right again. If you do not posess a tappet setting dial gauge, a normal engineers dial gauge will do just as well. The procedure is the same as using your feeler gauge except that you set the dial gauge up on the cylinder head with the pointer resting on the head of the rocker. Press down fairly firmly on the rocker valve end and zero the gauge. Next lift up on the rocker and read off the clearance, from the gauge, Use a magnetic base to support your gauge and repeat the pocedure for each valve pair.

Procedure of tappet adjustment


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.7675a52.gif

I did a valve adjustment and now it wont start


You adjusted the valves too tight. Back off of the adjustment before you break parts. You Have to set the rocker arm clearance when the engine is cold. (Not warm, not hot)

Use a feeler gauge.
The clearance for the Intake valves is .007 to .009. (7 to 9 thousandths)
The clearance for the Exhaust valves is .009 to .011 (9 to 11 thousandths)
You want a slight drag when you pull the feeler gauge through. This technique takes a certain amount of 'Feel'.
