My B20B With B16 (small Vtec) started to have annoying taping sound...
but the engine run great..
So Questions is it ok to ignore it ? was planning saving more money for the rear disc-brake conversions / and manual..
Or i shall change it ASAP ?

Fyi i using 10w/40 for my motor ~~

 

No lifters

Use engine stethoscope to pinpoint noise.

 

Is not my injectors too..
The valve leash ok too.. So that is the only thing i can think of..

 

You are correct that there are no lifters. These engines are OHC so they do not have lifters or rods that require valve lash. But you could have said that they do have valve tappets can and do make noise if the they are out of adjustment (kind of like valve lash).

OP, is the noise coming from the head or the block, only when it's warm or all the time?

and why 10w40?

 

Understood, but seemed premature prior to knowing location of noise source.

 

some times it happen more is the engine is warm...

but even is cold is still there...

and why 10w40 ? i have no idea the pervious onwer are using this. so i guess i just continue

 

10w40 is a heavy oil, not ideal for your application. it is possible the previous owner was using to mask oil consumption issues, quiet a knock, or both. if it is knocking, don't ignore it... stop driving it. like now.

 

Thanks for the reply.. Is not knocking sound is only like tap tap tap.. From the head.. Any recommand oil for my engine?
