SOURCE: Lifters knocking..

You might want to try an old trick that I have use twice in life but it accomplished the goal without problem.
When you are due for an oil change, preferably with the oil level somewhat low (don't overfill), add a quart of kerosene to the crankcase and let the engine idle for 20-30 minutes; do NOT drive it or race the engine since the kerosene is a lousy lubricant and you want it to function only as a solvent for the possible buildup of sticky crud that might be impeding things.
Drain the crankcase completely, allowing the thing to drip for an hour to get the majority of the oil-kerosene mix out of the engine and then fill 'er up with fresh oil.  
If you decide to try this, please post back to this thread so hat others might benefit from your experience.

SOURCE: 1997 jeep grand cherokee laredo replace collapsed lifter 4.0l il6

What motor do you have? The V8, you can remove just the intake manifold and the valve covers/rocker arms to remove the lifter. The V6, I believe you need to remove the head to access the lifters.

SOURCE: my valves are making a tapping noise do i need to adj. valves

Before adjusting the valves, 1. check the oil level 2. use an engine cleaner that you add to the oil (berryman's or equivalent) and run thru the engine for 30 minutes 3. change oil and filter 4 run and check for tappet noise. This may improve things without opening things up.

SOURCE: lifter tapping

Yes, you can have just a lifter replaced, but it could be other parts as well...like a valve, rocker, or cam shaft. The valve cover needs to come off for a better inspection.

Valve tap cause


Most engines now use hydraulic lifters and they can leak a little, this causes space between then lifter and the push rod. This results in a tapping noise that goes away when they get warm or fill back up.

What are the correct rockers/lifters to order when replacing ALL of them on 97 nissan pickup?


A normal sohc 4 cyl. has 4 intake and 4 exhaust.
That motor has 8 intake valves (2 in each cyl.) and 4 exhausts.
I thought all the lifters were the same ,but if what you say is correct you need 4 intake front ,4 intake rears and the 4 exhaust,if they were all bad.

Lifter noise


by changing the exhaust I take it that you removed the standard exhaust manifold and fitted extractors in instead. The noise may not be lifters but a exhaust leak form the exhaust not being fitted properly (gasket ) or just and gas noise as the exhaust valve opens that is normally silenced by a stock manifold.

Adjust valve tappets on flat head engine


I'd say that it all depends upon whether or not you have adjustable lifters. All flatheads have solid lifters, but most of the older (pre-50's) flatheads had non-adjustable lifters. Elimination of valve lash was accomplished by welding a glob of metal on the top of the valve stem and grinding it down to the required height. In the 50's, adjustable lifters were introduced, but it seems that at the same time, manufacturers increased the weight of the valves (thicker stem walls or solid rather than hollow stems). If you have adjustable lifters, try .008 on the intakes and .016 on the exhaust.

Bent lifter 2006 Saturn vue


Well, the lifters are metal cylinders that use a spring and fluid to push on the valves, so I doubt it is bent.
What you probably have is a bent intake or exhaust valve.
If that is the case, the cylinder head would have to be removed to replace the valve.

I have a ticking sound coming from the rear of the car in between the rear tries sounds like a clock ticking, what is it


An increasingly noisy ticking sound coming from your engine could indicate a lifter malfunction. I once had an exhaust valve lifter 'mushroom' where the cam makes contact with the flat tappet and the lifter wouldn't move up & down smoothly. This kept the exhaust valve from letting out the unspent fuel through the exhaust and the fuel had only one place to go: past the rings & into the oil. My cylinders needed rehoned.

It could be just a lifter gone bad. Unless you're into major HP(say over 400) you've probly got hydraulic lifters. This type builds up oil pressure to take up its 1/8" or so of slack they'll see when the engine hasn't recently run .

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.

  1. Disconnect the engine air cleaner-to-valve cover hose from the cover by compressing the hose clamp with pliers and sliding the clamp back, then separate the hose from the cover.
  2. Remove the spark plug wire separators from the valve cover and set the wire assemblies aside.
  3. Unfasten the three valve cover retaining bolts.
  4. Remove the valve cover and gasket from the cylinder head.
WARNING Do not use any abrasive grinding discs to remove gasket material. Use a plastic manual gasket scraper to remove the gasket residue. Be careful not to scratch or gouge the aluminum sealing surfaces when cleaning them.

  3. Remove the guide plate and the lifter.


To install:
  1. The oil feed hole in the lifter must face away from the oil feed hole in the cylinder head.
  2. Lubricate the lifter(s) with clean 5W-30 engine oil and install them in their original bores.

Make sure the lifter guide plate retainer tabs are towards the rear of the cylinder head, and the lifter guide plate tabs are towards the front of the cylinder head.
  1. Install the lifter guide plate and tighten the retainer.
  2. Install the rocker arms.
Do not use any sealer with a silicone type gasket.
  1. Install a new gasket and the valve cover.

Lifter noise.


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
