You might want to check the oil. if its not that then it could be your valves that need to be adjusted

What causes a tapping noise when the engine is running in a 2002 Saturn L200?


Lifters, push rods and rockers arms. That's what does it. To check lifters. Start the engine and get it up to operating temperature. Put a half quart of transmission fluid in it and let it run. If the tapping goes away, let it run for about 30 minutes. Drain the oil and change the oil filter. Refill it and add some oil treatment first, lucus, slick 50.. what ever you prefer. If the noise doesn't go away. Look at the rocker arms and push rods, they should be polished, replace them as needed, I would still put the additive in.

Please check to see if the slapping noise is from the belts, the idler , the water pump or alternator. Also check if this is the tappets or the valves, if so this might require a check up after removing the valve door covers. Check for oil pump pressure and also for settings of the valves.

The cam followers are self adjusting,so an engine flushing agent and new oil (10/40 semi synthetic), should sort out the "tapping" noise,When the engine is hot run at 3500 revs for 30 secs to reset gaps

Tapping noise like a bad lifter Replaced lifters, it is still tapping One guy said it is GM knock does not effect running of car


one guy is right,it could be a vauxhall tap,even new vauxhall cars do the same.but lets be serious?to calm this and slow down the noise,get the tappeds checked out .it will need the cover removed and with engine running feeler gauges placed between tappeds it will revel one tapped loose and can be fixed within a couple of secnds.adrian,,,

Hello there. I've recently bought a 54reg mk5 golf 2.0 gt fsi and the engine is making a tapping noise - even when it's been running. Is this normal?


a light tapping noise is quiet normal .Use a flushing oil before you change the oil and filter.then use 10/40 semi synthetic(as recc by VW)when engines at operating temp run at 3500 fo 30 secs,this will "charge" the hydraulic tappets,a cold engine has a valve rattle for about 15/20 secs but if longer then cam followers faulty.normally at 120,000m(roughly)
please leave feedback..

Engine tapping.......


Tapping and oil burning when both are together are tappet trouble. Get another mecanic to check. Any other part of the engine tapping would get a lot louder after a lot less miles. Sounds like tappets and valve stem seals are worn hence tapping and oil burning.

I forgot to put oil into my engine now my chrysler grand voyager is not running right now,it is now making a tapping noise,do i need a new engine and how much will it cost


When you say "tapping noise" it names off several problems, please clarify :)

- Can the car "turn over" (aka try to start)
- What do you mean it "doesnt run" it wont start - or - does it not drive forward/backward (but will start)
- When does this tapping noise happen?
- How hard do you drive the voyager?
- Can you do your own mechanic work (for small - medium sized projects)?

IN lite of my coolant leak, a bad pump will somtimes have a tapping noise. At time s at crank up there is a tapping noise but it sounds like its from a rod tapping from lack of oil. Could this be related...


First, change the pump. If it's bad just to protect the engine it has to be done! Second, The noise you hear has to be isolated. A sticking lifter can cause a tapping noise and is more common than rod or other bearing failures. BUT, if you have "cooked" the engine oil from repeated overheats or higher than normal engine temps all bets are off. If you have an oil pressure gauge, what is the oil pressure? Should not be below 15PSpsi running, in or out of gear.(in reality, should be much higher than that!) If too low, then you have a problem.If normal, change oil & filter.
