Since the 4.2L is a push rod engine, you have the 4.6L or 5.4L which the valve train system is the same. The lifter can be removed without removing the camshaft by using two special tools that can be purchased from any tool house that sells special tools in your area. Tool 1 is a spacer to prevent the valve from traveling too far (damage to seal), Tool 2 is a valve spring compressor, that uses the camshaft as a fulcrum to depress the valve and spring enough to remove the rocker assembly, use a plastic pen to determine piston location before using the compressor tool, you want the piston approximately 1-2 inches below TDC, once the rocker assembly is removed the lifter can be pulled out the top. It is very improtant that the rockers and lifters be kept together by location (ie. exhaust number 3 rocker and lifter together) and installed back in thier original positions. If you can not get the special tools, then the only other option is to remove the cams. Hope this helps, let me know

Replace lifter on 5.7 hemi


I take it you have determined which lifter it is? The task is relatively easy if the lifter in question is not heavily worn by the camshaft. Remove the centre manifold and various pipes etc. You will have to drain the coolant system.
Remove the centre or valley gasket/shield to expose the lifters and push rods. Re determine which lifter it is and turn the engine until that valve is closed, releasing most of the load on that push rod. Remove that rocker cover and loosen the nut/bolt in the centre of the rocker arm until you can release the push rod. Now here is where it gets tricky because as a matter of design the lifter rotates during operation to even the wear on the face of the lifter and cam. You can get a tool from a parts house or online that has 2 small jaws that you expand into the face of the lifter under the top groove and you can pull the offending lifter out. Its quite possible that after high mileage there is a burr on the lower end of the lifter face and you should not apply more than moderate force to extract the lifter. If you do you risk pulling the burr through the block bore and effectively reaming it oversize, this is not good and could affect the fit of the replacement.
I regret to say that if its tight to extract, the only solution is a block strip in which case get a kit of camshaft and lifters and replace all parts. If the lifter has failed due to sludge, which is a common problem on v8's, then its likely they could all soon be in trouble. It is possible on some lifter designs to disassemble the lifter, clean all the parts and replace it in the block but you have to weigh up the time taken to do the job plus parts as to whether its better to take the whole engine out for rebuild. If mileage is high, lots of short runs, cool conditions leading to low oil temp and sludge then consider a rebuild before bothering with one lifter.
Good luck.

X25xe noisey lifter


Sounds like a bad lifter or a bad lobe on a camshaft. Not real familiar with the brand, sometimes you need to pull off the valve cover if it is a pushrod design and check with fingers on rocker arms while engine runs.

But if this is an overhead cam you would need to pull the camshaft and look at cam lobes. Then look for flattened lifter face. Some overhead cams can have lifter discs to adjust gap between lifter and camshaft. Some of the old VW engines used this system. It worked pretty well, but you needed discs on hand to make precise changes.

My Nissan 1400 makes a clicking noise in or near distributor and sounds like runnig on 3 cylinders


Hi, sounds like to have a failed lifter/lash adjuster. If you drive the truck, the lifter will eventually damage the camshaft. I recommend you replace all of the lifters. If you can tell me what engine you have, I may be able to provide instructions, to replace the lifter. I'm not familiar with this model, but from what I can read online, it appears to use a pushrod engine. In this case, it is likely the cylinder head must be removed to replace the lifter.

Have a lifter ticking noise in my 1996 buick regal. What does it take to repair the problem


The repair depends on the exact cause. Typically one of two things happens.

A lifter fails to "pump up" and looses pressure. Sometimes oil system cleaners can help this.

The other thing that happens is wear realted, called a collapsed lifter, this issue requires replacement of the camshaft and all lifters. I recommend against replacing only a collapsed lifter, as the cam lobe usually gets damaged, as the two parts are hardened and wear against one another (cam and lifter).

It is always possible to have a rocker arm come loose. The only way to know for sure is exploritory surgery.

The directions to fix involve replacing the lifter, and all worn components... Often this is the camshaft, gears, and all lifters...Fairly major surgery for most guys.

Hi i have a ticking noise in my vg30e pathfinder, i believe it may be a hydrolic lifter, what are the adjustment specifications


The lifters on your vehicle would not be adjustable, so depending on mileage, a lifter could need replacing. Listen to this sound to determine if it is at engine speed, or at camshaft speed, which is half as fast. If at engine speed, it could be any number of things. If at camshaft speed, it couild be a broken vavle spring, a sticky valve or a noisy lifter.

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.

Ticking noise comes and goes i took it to the dealer they said the camshaft and the#6 lifter is bad do i have to replace the engine


should be able to rebuild. sounds like you will need a new cam and lifter set. Cam and lifters could be replaced without completely rebuilding engine, but I wouldn't recomend it. All the metal from the cam and lifter goin down will have already gone through your oil system therefore engine really needs complete disassemble and cleaned.

Lifter making noise


depends, how long between oil changes, how many miles, try and engine flush, sometimes debrise adn sludge will cause a lifter to stick and not move freely causing the tapping noise you hear, if this doesn't fix or quiet the problem it may be to far gone, but if you really love the car get a tear down manual and go to work....put aside a weekend and about 500 dollars it'll be a job
