Thanks magnus, i hope Dave will take you up on that offer, you can't beat experience and Dave--- deserves--- all the assistance he can get, very few guys are as persistent as he is and i can't prase his efforts enough.
If the piston is made out of plastic it may be affected by heat somehow.
Here is the spring in front of the piston;
___So does this mean that if the valve is not threaded down completely when it is installed (like mine was when I removed it) then the ECM will automatically compensate and send the proper signal to the motor to properly locate the valve?
Depending on the forces involved it may be a reason for failure, although not likely, think the spring may be part of damage control or the problem depending exactly what it's function is.
___So, then the fact that my valve was not threaded completely to the bottom of the threads when I removed it (the way it is supposed to be when installed) makes no difference? I was hoping that this was the root cause of my problem.
It may be that the shaft has moved on the bearings and mis-aligned itself somehow but that is just speculation from me, hence the question for pictures ( magnus? ) because once the iacv is mounted the comparison is no longer possible, we know the iacv fails sometimes, we don't know how though, here is your opportunity to find out, all we know is the pictures magnus posted regarding his iacv replacement.
Thing to remember is that the engine ran fine for a long time when you got it, if the piston was mis-aligned ( position-wise ) it would have shown up very quickly, so something has changed some time later.
Q; does the shaft rotate freely?
