Pull 5 degrees out of the entire base b timing map
if knock doesnt change then its very likely rattle vibration problem its a common issue
if the knock goes away with 5 degrees out of the map then likely fueling ignitin timing issue

Hey Steve, I am pretty sure I've narrowed down my cruise knock to having UEL headers, no factory heat shields, and being down in South Florida where it is really hot 75% of the year. I do not have header wrap because I don't want my headers to crack and in the event I have an oil leak, I do not want my car up in flames.
Note: Before I got an oil cooler, after doing some light pulls I would get to oil temps of upwards 240+ degrees Fahrenheit. It wouldn't take me any more than 3 minutes driving to get to 185 degrees Fahrenheit.
Tagging @
Kodename47 so he sees this too. What do you guys recommend? I was thinking of wrapping my OP + FP in header wrap, but I am hesitant that my OP / FP could crack.
Please let me know what you think
