Their's a big difference betweene a Knock & a Spark Knock !!
How many miles do you have on the engine??
It is very hard to know what you are hearing without hearing it
myself.
If im correct i beleive those engines have hydraulic lifters in them. Thats probably whats making the noise. it's useless to replace them. It's not gonna affect your engines performance. just let it knock

you don't adjust hyd valves, use t- to spec- 90ich. are you makeing fun, Ha lol on me, however, do you have a solution to this problem.
Clarifying Question, My apologies, I have what seems to be a valve or rocker knock at start up and seems to increase at acceleration. As previous stated, I have done some diagnostic trouble shooting, and am still clueless as to what is causing this problem. If you can please help me.
One more time is this spark knock?? was really curious about the valve adjustment, I guess you kinda did run the valves we call it in the trade.
Do you mean spark knock?
HOW DID YOU ADJUST THE VALVES? THEY ARE HYDRAULIC??
I'am Like Dennis, Does it knock all the time or when your driveing?
