How long has it been from oil change. Have you checked Oil pressure? If filter is old and dirty fluid needs to warm to be thin enough to get enough volume to valve train. If oil pump is getting weak it will not pump sufficient fluid to valves at low RPM. First change oil and filter. After that make sure pressure is in spec's.

Tapping in engine


You could have a piston slap from worn rings or oil passage is blocked or oil pickup tube blocked or valves have worn guides or lifters loose.

Tapping Sound from 2004 GC 4.7l Engine


If the tapping noise speeds up with the speed of the engine, it's a worn valve lifter.
If the service light is on, change oil and filter, if tapping is still there, the lifter is the culprit.

91 previa LE, 205K miles. diving Tucson to St George, UT, 800 pound load. After 3 hours at 65-75 mph, had to slow down as engine was struggling to keep up speed. Stop for gas, and engine was "tapping"...


It is probably a oil pressure problem. If there is some sort of small blockage in an oil journal it could stop oil from flowing to the lifters which would cause the the tapping noise. at this point the best thing to do would be to try and flush out the engine with some sort of desludging agent. One thing i usualy do is drain the oil and re-fill it with atf and run it for about half an hour or an hour and then re-drain and replace with normal engine oil. transmission fluid contains tonnes of detergents and should help clean out any blockages.

There is a faulty sensor or valve. Sounds like a valve. The best thing to do, is take it somewhere that can diagnose the trouble code. Autozone can I believe, and they can tell you exactly what's going on with it.

ENGINE HAS A TAPPING NOISE AND IT SPEEDS UP WHEN THE ENGINE SPEEDS UP, SOUNDS LIKE IT IS IN THE DRIVERS SIDE FRONT


Make sure the oil is not low first, this sounds like valve trane noise, check the valve rocker clearances they may be loose.

Check Utube for lifter tap, valve tap, and rod bearing noise. If you pull each spark plug one at a time, plugging it back in after each one, the tapping will go away if it's a rod bearing. At any rate, on your next oil change add some valve-medic or similar additive for valve noise. Make sure you follow direction or you will get massive lifter tap if you pour it into a cold engine.
