a tapping sound from under the valve covers at any eng.speed. some eng. have adjastable valves but I sugest you use a repair manal for you car type or have a good mecanic do it for you
if it is cracked or the gasket is bad sometimes they sound like ticking lifters. look for carbon deposits at joints and on the manifolds themselves.
In most cases, you can tell that your lifters are bad, in your car engine, by the ticking noise. A bad lifter will make a tapping sound.
yes, if its ticking bad and you like the engine, get it fixed
on a 98 ford taurus what are the symptoms of a bad hydralic valve lifter
Yes it can, but try to isolate the sound by using some thicker weight oil and/or oil additive like lucas to quiet the ticking lifter. If the noise doesn't change it's probably an exhaust leak, if it quiets down you might have a collapsed lifter.
You can't fix a bad lifter, replace the bad lifter with a new one.
Answerif im not mistaking that sound should be the solenoid opening and closing.Improved: it also could be a sticky lifter, a lifter going bad, exhaust leak, or a spark not grounding right.
Sounds like a piston hitting the cylinder head. A lifter will usually tick, but a piston will sound more like this knocking noise.
This is a toughie. First you have to decide which lifter it is then pull the rocker cover and find the rocker arm that has play in it. Then look at the lifter and where the push rod rides should be stuck down further in the lifter bore than the rest. Or press down on the inside and if it goes down over 1/8 inch and is springy the lifter is bad.
Maybe, or you have a bad lifter .
Depends on how the lifter has failed. In most all cases you will have loss of power and there may or may not be a ticking or tapping noise. There will be a "misfire" in the cylinder that has the bad lifter, There is loss of fuel economy. The car will fail emissions testing.
they would go all mental and start a gran theft auto like everyone else
