Hickory is in North Carolina why do you ask?

 

just wondering

 

I'm only seeing knock when I take off now

 

how much?

 

Usually.3 to 1 but when I left class today I saw one knock of 2.1

 

Does it go away slowly or instantly?

 

It goes away instantly why?

 

well from the looks of a couple of your plugs you may be getting oil in the cylinder i would do a comp test and a leakdown test

 

if it goes away instantly it is most likely false knock.

Knock sensors are really really sensitive, and they detect a certain sound frequency that the computer determines is "knock" and then retards the timing.

However, if something is banging up against the block or matches that sound frequency it will show false knock. the PCM is designed to pull timing slowly and usually at .7 per second. so if you were getting true knock and you had 3.0 it would go 3.0...then 2.3...then 1.6...then .9 and so on till it goes away.

False knock will show knock, then disappear completely. At least thats how It was explained to me.

However, I would recommend doing a compression test just to make sure.

 

I have a video of it running should I will upload it

 

Couldnt get it to upload guys gonna do a compression test n will load results

 

Ok so it sounds like I have false knock. So then what would cause the big decrease in boost? Would the bypass valve maybe cause this

 

Nvm guys it still boost the same if not actually a little more I guess I just freaked when it bogged down on me a little. It is really ******* cold here so Im figuring that is affecting my vaccum and boost a little but I will keep things posted if something does happy. Thanks everyone
