Funny how car maintenance works

[dsaundry]

Have you determined if it is bottom end knock or top end? Bottom end might be the early indication of a rod starting to let go. You say that the timing does drop out when it is knocking which is normal as the knock sensor would cause it to drop. It might also be a valve issue as well. As big of a pain as it is, its time to pull the heads and inspect..I would really like to hear it first...

Sorry dont mean to hijack a thread here....
