Re: Tapping sound in The engine Head
Sounds like lifter noise. The best solution for lifter noise is, change
the oil use a good quality oil , i would recommend a synthetic oil or
at least a couple of quarts. Then get a bottle of MARVEL MYSTERY OIL
this stuff works good add that to you oil when you change it and that
should clear up any lifter noise. Another thing that might help use a higher grade gas a couple of times.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Probably a combination of parts. Lifters and or rocker arms. Could be dirty lifters also. If your ready to change oil, what I do is get the engine to operating temperature. Pour a half quart of transmission fluid in and let it run 15 to 20 minutes. It's high detergent and helps clean out the lifters. If the lifters are tapping from dirt, this will stop the tapping or at least quiet it down some.
Possible there is a need to set the gaps in the valve clearance and so you might need the assistance of the service center. If the regular service check was not done please include this work as a routine check up. If the noise is high specially in the morning please have it checked up as it can be due to problems with engine bearings.
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
check oil pressure possible valve tapping -start vehicle and open hood if the noise is on top and sounds like metal tapping u may have a problem with a bad lifter ,oil pressure not lubing head,bent valve/push rod,loose rocker arm. if noise towards front check belts and pulleys-power steering level
step 1: remove the valve cover///step 2: if you see nice gold color around the rods, lifters, and valves and you do not see any black sludge in between the lifters the engine is pretty clean and will also tell you if the car religiously has been getting its oil change every 3k. Also start up the car; listen for tapping noises BUT MAKE SURE YOU HAVE THE VALVE COVER ON. If you dont hear any abnormal tapping noises then your engine is solid. Try to stay away from arco or cheap gasoline. shell, mobil, and CHEVRON is really good gas for the engine.
