Knocking On Idle
copied from another post i made on diff forum
I searched and couldn't come up with a conclusion so here it is...
today i went out to pick up some spark plugs and other things from the store... so i turn onto the main street and hit it in first and then shift and slow down to turn... im turning on my street and hit second and see at like 4000 my boost is going over 5 psi... now on idle there is a slight knocking and when i rev after it drops to about 25 vac and when shifting at like 3000 it drops to almost 30 vac. I switched out the spark plugs to new ones... same problem...all hoses connected... we just tuned the car yesterday...i have no wideband in my car so couldn't tell you any a/f ratios... also the wastegate is surging a lil on idle...it starts where its pretty much almost closed and surges a lil open...
updated.....
just went out to check and the car is making a slight ticking noise now along with a slight bog type sound...this is the new sound, different from the first...

Re: Knocking On Idle
you happen to have an oil pressure gauge ?
i'm curious as to what kind of oil pressure your running at an idle compared to what kind of oil pressure at 4K
at the same time, sound more or less like an ignition ping ? or just something knocking ?
have yah checked the oil to see if there's any metalics in the oil pan?
what all did you do to the bottom end of the motor ? how long have you had the setup like this ? fresh rebuild ? or turboing a 200 K motor ?
I don't understand why you come here all high and mighty.. and start being a dick ..on your what ....12th post .....get of your high horse, and start respecting people on here ! most of us are here to help you, or call you names, if your gonna be an ***....your gonna get more of the name calling than help ,
