I was quoted $500 to replace all the lifters. Is this a good price?


That is a ridiculously high price to replace lifters on a 4 or 6 cylinder engine. On the Mitsubishi 4 cylinder motor, the only thing that is needed to do is remove the valve cover and remove the rocker rod. (2 rods which hold the rocker assembly.) Next is remove the lifters from the bottoms of the rockers and pop in the new ones. Be sure to soak the new lifters in oil for 24-48hrs prior to install so they are pre-filled before install. Replace the rocker assembly and torque down to specs. replace valve cover and then start the vehicle. Check that there is no loud tapping noise and do not race the engine until the lifters have pumped up with engine oil. You should replace oil and filter for this engine work as well.

How to fix nosiy vavle on 1994 chevrolet c 1500/myself


The way a mechanic would do it is to remove the valve covers, feel for rockers that are ticking with your fingers. Note the locations. Pull the intake off and replace the hydraulic lifters for the offending one(s). If you find several, just replace the whole set (16).

Alternatively if you are really skilled is to remove valve covers and distributor. Put a small light down the distributor hole to illuminate the interior lifter valley. Using a small magnet and etc, fish the offending lifter out and up the distributor hole. Reverse to install a new lifter. I have fished lifters out like this from the very front of the engine. The key is to illuminate the engine valley with a small good light. You can see what you are doing by looking through the push rod holes.

Where are the timming mark for 1993 nissan quest


ignition timing is normaly on the harmonic balencer (the pully on the crank that drives fan belt).if not it will be on the fly wheel and there will be a small inspection plate and pointer.if your looking for vaulve timing / cam timing remove timing cover on the front of engine block (dont mess with this unless you know what your doing)..if your engine is belt or chain driven over head cam never ever turn engine backwards or the timing belt/chain can slip/jump and then the vaulves can hit the pistons upon starting ruening the engine

I have a loud ticking under my valve cover. 97 ford escort. I think its a loose valve but is it some thing i can fix. I know a little about cars. but not an expert


not a valve, but a lifter. I will paste procedure below. You judge if you can do it or not. Recommend you replace them all while you're in there. If you let this go, the lifter will wear out the camshaft. Lifters are $22 each, and you have 8 of them. You will also need a new valve cover gasket.
Please let me know if you have questions, and thanks for using FixYa.

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.

Need instructions on how to change the lifters in my 1998 Chevy S10 2.2L


Please don't forget to rate!!!!

2.2L Engine When installing new lifters, a pre-lube should always be applied to the lifter body. It is also a good idea to prime hydraulic lifters by submerging them in clean engine oil and depressing the plunger using an old pushrod. This allows the internal components of the hydraulic lifter to coat with oil before initial operation in the engine. All lifters should be replaced when a new camshaft is installed.
If any valve train components (lifters, pushrods, rocker arms) are to be reused, they must be tagged or arranged during removal to assure installation in their original locations.
  1. Remove the rocker arm cover.
  2. Remove the cylinder head assembly from the engine.
  3. Remove the bolts retaining the lifter anti-rotation brackets, then remove the brackets.
  4. Remove the hydraulic roller lifters from the bores.
  5. Inspect the lifter and lifter bore for wear and scuffing. Examine the roller for freedom of movement and/or flat spots on the roller surface.

Use a lifter removal tool to remove the lifters from the bore

To install:
If installing a new lifter, coat the lifter body with a suitable camshaft pre-lube
  1. Install each hydraulic lifter to its bore being careful to align the flat sides (top) of the lifters with the flat sides of the anti-rotation brackets. When properly installed the flat sides of each lifter are aligned parallel to the anti-rotation bracket. The roller at the bottom of the lifter is parallel to the camshaft lobe.
Make sure to properly align and install each lifter as improper installation of the lifters or brackets could result in engine damage.
  1. Install the anti-rotation bracket retaining bolts and tighten to 97 inch lbs. (11 Nm).
  2. Install the cylinder head.
  3. Install the rocker arm cover.
