If the engine runs good and has high mileage, it might be the timing chain guides that are worn out

You could try running a flush chemical in the engine oil just prior to changing the oil, and then using synthetic oil. This may free up the little tiny valve in the lifters and reduce the noise. At the very least, it will help prolong their life. It is a very big expensive job to change these because they are generally replaced as a set and they are not cheap, but replacement is often the only true fix.

Yes, but there is still a lot of stuff to move out of the way to get in there and pull them. I would try all the chemical remedies for sticky lash adjusters (oil flush, marvel's mystery oil, etc.) first, then check the timing belt to see if a worn timing belt has let it slip a tooth and the valve timing is off for that reason before digging into the lifters. There used to be a forum that had video and audio from a subaru legacy this model before and after swapping out a bad lifter. Google for it and see if the noise matches.

SOURCE: replace lifter

Lifters are usually replaced in sets with the cam or rods and rockers, replacing just one lifter, rare, but if it is making noise, then just locate the trouble maker, you can run the engine with the rocker cover off, find the bad one, shut of engine, loosen up the rocker, twist it out of the way, pull the rod out, then go in the hole with a piece of heavy wire, rod, steel, with a cut in the bottom to hook on the lip of the lifter, then pull it out. Put it all back, you should be all set.

I had heads replaced on my 2004 Dodge team 1500 5.7 hemi due to valve and spring issue. Then lifters became very noisy so replaced those also. Truck runs ok but lifters are making noise at start up now...


the hydraulics will leak down after the engine has been stopped for a while . The noise on start up will be until the oil again fills the lifters. If it is getting really cold (under 32F of close to 0 c) then you may have to consider a lighter viscosity grade of engine oil (10w-20 or 15w -30) the manual will have the recommended viscosity of oil for cold areas or you can check with the oil catalogue at any auto parts store.

Why does the initial cold start on my2.5L 1996 subaruhave noisy hydraulic lifters


Noise lifters on a 2.5 engine of the first generation are an unusuak problem; these engines are known to have "piston slap", which can sound fairly similar to noisy lifters. I owned a Forester with those symptoms and drove the car for more than 3 years without doing anything about it. The only real cure would be an engine rebiuld, which is , in most cases, not worth the effort, especially since most of the "stricken" cars continue to work without any problems for a long time.

Previous problem - hydraulic lifter noisy - car first lost oil hose to turbo - before this lifters, etc. were fine- 2003 PT cruser w/ turbo


that oil hose probably lost enough engine oil to starve lifters... but then again, that engine shouldn't have lifters since it an overhead cam... suspect your tappets were starved of oil... might come around, might not...

Valve tapping ccan I fix it myself before I take it to mechanic


Inspect/Test/Service/Replace Hydraulic lifters can fail for several reasons:
  • Dirt lodged in the check valve can allow the lifter to leak. Too much wear between the lifter and the body can cause excessive leak-down. This results in a noisy lifter.
  • A lifter might be noisy because of an oil pressure problem.
NOTE An oil pressure problem will be evident on hollow pushrod engines if no oil is reaching the rocker arms.
  • A lifter can become stuck because of varnish that accumulates between its plunger and body due to a lack of periodic oil changes.
  • A stuck lifter can sometimes be freed up by the addition of an additive to the oil, or by spraying fuel system spray cleaner down a hollow pushrod oil channel.
  • Lifters that stick because of varnish buildup can sometimes be loosened up by squirting carburetor spray cleaner down the hollow pushrod lubricating channel, where it contacts the rocker arm.
Hydraulic lifters are not rebuilt because they are relatively inexpensive. It is possible to disassemble and clean lifters but they must be reassembled with their mated parts. Because of the labor time involved, this procedure is usually impractical.
Sometimes a piece of foreign material becomes lodged in the lifter check valve. If the lifter is removed and disassembled before serious wear between the lifter and cam lobe results, it may be cleaned.
Worn mechanical (solid) lifters can be reground.
  • The base of the lifter is ground to a radius on a special lifter grinder.
  • Roller lifters have a longer service life than standard lifters.
  • Wear can occur on the roller pin. Some of these pins are serviceable.
It might occasionally be necessary to disassemble a hydraulic lifter to clean it or to inspect it.
  • If this is necessary, disassemble one lifter at a time and pay attention to the order of the check valve assembly.
  • Lifter disassembly is done by pressing down on the pushrod seat with your thumb and using a screwdriver to remove the snap ring.
  • Remove the plunger from the body; this may require tapping the body.
  • Next, remove the check valve assembly.
  • After thoroughly cleaning the lifter components in solvent, visually inspect them for signs of wear.
  • If the internal components pass inspection, the lifter can be reassembled.
  • During reassembly, cleanliness of the parts is of utmost importance.

Looking to adjust valves on a 2.2 chevy motor in a Corsica hydraulick lifter


Sorry but there is no valve adjustment with hydraulic lifters - can turn the lifter upside down fill with oil - let sit for a while and then tap on the lifters to see if they make noise - if noisy replace.  Camshaft may be worn on the lobes or may have jumped timing if belt.

Do the valves need periodic adjustments in a 1999 Chevy suburban and how many valves per cylinder


The valves never need adjusted, .Do to hydraulic lifters and zero clearance.The rocker arms are torqued to 35 ftlbs.So you never have to worry about it.If there is a noise have your lifters checked:)

Engine runs good then I hear a tapping noise. could I have a bridge broke inside the engine? 1987 brougham with a 350 Olds motor.


noisy lifter is number one....get an addititive like hyper lube and run it 20 min on the freeway,. lifters are hydraulic and get gummed up with a varnish like substance. an additive dissolves it and restores the hydraulic lifters action,which operates the pushrods that operates the valves

Noisey valve lifters in 2001 blazer


I suggest Blue Devil products for noisy valve lifters. If they are too worn or one of them is broken , no product will work . The lifters and valves have to be overhauled.
