Annoying sound of engine tapets in suzuki cultus

[5644-8788]

guys anybody drives a suzuki cultus euro 2 models. the tapets of my engine a are making alot of sound. the' tik tik' sound that comes from the engine is becoming very loud and can be listened when sitting inside the car with windows up. i have taken my car for tuning for about 3 times and even went to suzuki center also. they said its the genuine sound of the engine. but they said that they will do tuning and the sound ' will become less. the sound was lowered but after driving few kilometers the 'tik tik' sound is coming again. the sound is too annoying. overall car is running fine. please suggest a good solution for it. P.S when i changed my engine oil from suzuki engine oil to zic x5 after then the sound has started coming.

Umm possible valve tappets need adjusting to the correct clearance also check the correct oil is in

Too thin oil inside the car which is slipping past tappets too soon...can be a cause..
Another can be (as my car had it too) that some rocker is slipping and not working as per its path..that created a lot of sound in my case..i had to change two rockers for that..in the pic attached, the first and third ones from right..

dear sir,
The sound will disappear after 400 to 800 km because it become more viscous. Yes the zic oil is very thin oil initially it will give sound but disappear after some running. If u still think the tappets are too lose don't gauge the tappets when the engine is warm. Standard is that when your car is cold and obviously you have to leave ur car in evening at mechanic place and he will do the tappet gauge at early in the morning, if u will gauge it in warm condition then when it will become cold at morning it will give starting problem in morning more over the pick of the car also effected by tight tappets. I suggest not to finger so much to the engine just wait and observe it more. Not take too quick steps.
Regards

tik tik'

So can any one tell sound difference with 20w-50 Mineral & 5W-30 Synthetic

Are you sure TIK TIK sound is of Tappet? May be u r mingling this with Engine knocking sound.

For this purpose, finish your Petrol to "E", then fill Full tank Petrol to "F" with High-Octane, then observe the sound.(Preferably add some Hi-Octane treatment fluid for better performance)

If it would be Knocking sound, then it must be disappeared with High Octane Petrol
