No guarantees, but it may just be that oil is draining back into the pan when the car sits. Once you fire it up, it knocks till the oil is pumping again. Especially if it only does it after the car has been sitting for hours and hours. Good Luck!

Another trial fix is using a top quality oil filter, that is one that has a better anti-drain back valve inside. I used a "Fram Tough Guard" on a similar problem and the noise went away.

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.

I ran my 2.2 Vauxhall astra very lo on oil, all of a sudden it started making a loud tapping noise coming from what seems like the very top left hand side of the engine, I immediately filled it up with oil...


Yes the noise is the lack of oil to the cams as these will lose the oil pressure first ,these engines are using hydraulic tappets so no doubt the oil was squeezed out which means the tappet gap is too wide ,i think you may be better off just getting another engine from scrap yard ,new timing belt and fitting this engine as no doubt a local garage will try to give you a complicated excuse for a bodgy repair that will not last long,you would need to remove the rocker at the least and have a better look to get some idea of the damage ,if the cams are damaged then its another engine or trade it in quick after adding a can of STP

Hi, i have a toyota fielder 1.8cc with a some problem which has now come up. when i switch on esp in the morning after staying overnight, it produces some really annoying sound from the engine. when the...


If it is a 'squealing' noise it's probably the alternator/power steering drive belt. Before you turn on the engine in the morning, lightlt smear or spray some oil on the inside of the drive belt to lubricate it. If the squealing stops/disappears, then that's the fault ..

That squealing noise can be caused by an incorrectly tensioned belt, or a worn belt. Replacement is the only option.

The other frightening sounds can best be described as 'rattles' or 'tapping'. When a car stands overnight all the oil drains back into the sump (oil/pan).

There are two things (usually) that can be cause the rattle/tap:
1. Because the oil hasn't been pumped around the system, at start up worn big end bearings can rattle and tap on the crankshaft until the oil 'fills the gaps'. The tapping/rattling goes away as the engine warms and oil is pumped around the lubricating system.

A 'bottom end tapping' is a symptom of worn big ends (they are bearings at the bottom of the piston and fit around the crankshaft).

2. A rattle/tapping from the top of the engine can either be a worn camshaft or 'lazy tappets'. Again, when the engine warms and oil gets to the camshaft and tappets (also called 'hydraulic lifters) the noise will disappear.

If your car has this rattling/tapping noise - identify whether it is coming from just under the rocker box (ie the camshaft/tappets..) or the bottom end of the engine (big end bearings).

If the noise is coming from the top of the engine, try an oil change with a can of thick 'additive' included. A lazy tappet (lifter) isn't too much to worry about. A worn camshaft will affect the performance of the engine, though continue to do its job. An oil change with an additive included may help in quitening things down.

A bottom end tap/rattle (or 'knock') - the sooner that is sorted out the better.

On my 1994 L200 3000 mitsubishi there is a tappet which has stuck and is rattling,can you help.


Mits are well know for top end noisedue to hydrolic tappets. Note we are talking about a tapping or clicking sound here not a knock. You can try using an engine flush product if the noise is bad and then changing your oil. Follow manufactures instructions on the engine flush product. I have also used Marvel Mystery Oil (available at Walmart and most auto parts houses) with some success on this. Generally if the oil is not changed regularily eventually the tapping noise starts happening. FYI: hydrolic tappet can and do fail but generally the noise is associated with not maintaing oil changes

Fast tapping sound from top drivers side of engine when excellerating fast any ideas?


Tapping on the top of an engine is caused by excess valve tappet clearance.

You can have a worn rocker arm also.

Loose valve tappets usually are the loudest at a constant engine speed. when there is little torgue being produced.

A worn rocker arm with a bearing problem will make more noise during acclleration.
