i have a y8 on my 91 si i jus recently put.every time i drive above 4000 rpm it makes like a grinding noise.yesterday i was recharging my ac and wen i went to rev it i can hear a clicking noise in the head .could my engine break down any time soon.oh and i havent connected the vtec yet.could this be a problem.

 

i think you need to re-write your question because i can't understand it for sh*t but it sounds to me that you might need a valve job

 

x2!!! you need some valve adjustments.

 

damn.never done this.thanx.

 

It's easy.
