Back in March 2013, I got a Killer B oil pick up tube installed in my 2005 STI. Car was otherwise stock. I decided to do this because I had read the failures of the stock pick up tube. Ever since that install, I have had knock while cruising (up to -12*), and no knock in boost or WOT. Also, my oil pressure is normal according to my gauge.
Trying to diagnose this issue almost 2 years later, it was mentioned to me by a tuning shop I was talking to that it could be the pick up rattling against the pan causing an issue.
I don't want a discussion about why/how I think it's false knock. My A/F ratios, DAM, and FKL are all exactly where they're supposed to be, and motor mounts, trans mount, and heatshields were all already checked. Can anyone offer ANY thoughts on this? I have limited funds to fix/diagnose this problem and would like to have it done efficiently, obviously. Thanks for any info.
