ok...heres the deal.....

5.3 Radix'd....FMS dyno tune.....

I just got my 3" pulley in after Futral tuned it.....i threw it on for the hell of it and goin back to get it tuned this week. I took the truck out after work to show a few guys and they talked me into takin them for a cruise. I opened it up to WOT a few times and all was good. Then on the way home, i noticed this knocking/clicking noise. Popped the hood, and when i gave it gas, there was smoke coming from what it seemed like my intake. At Idle i can still notice the tapping noise and it sounds like its coming from the blower!?!?!? HELP!!!!! One of my buds just graduated from UTI and he said it doesnt sound like piston slap(although ive never heard piston slap in person). What can this be?!!??!?!!?!
PLEASE HELP ME!!!!!!

Was it tuned for the smaller pulley? If not, I would get there ASAP. The extra boost probably caused a good bit of detonation, which could have done some damage.

 

 

i'm no expert but i would suggest pulling the plugs and see if you shattered any of them, and maybe a compression check to see if you did any damage.

 

/\TTT/\

sorry to hear man, hope its nothing serious.....

 

wow... no ****...

 

it was tuned for the 4.3 pulley, not the 3"

what kinda damage could i be lookin at?

 

Start your truck and take the oil fill cap off. If there is alot off
steam and oil coming out, ( a very little bit is normal) Than
you probably busted a ring land. Let us know and best of luck.

 

You could have broken a piston,detonation can do a lot of damage quick.Pull the plugs and see what they look like you may have only lost a plug electrode.If that's the case a plug change and a more conservative tune of your timing could fix the problem.

 

i took a look at it for a few mins today. i noticed an oil leak right behind the EGR, right where the blower meets the block it looks like. a buudy of mine said the knocking might be the cam hitting thie lifters without oil?
