Tired of rod knocks...

ill try that.
the thing with the burnt spot was that it was just as loud then as it is now. it never gets louder it just makes the exact same sound the same volume but this time i have some flaking in my oil so i know its further gone.

anybody with experience hard mounting these know if it makes a difference? I've heard of people having issues with hard mounting certain engines because at a certain hertz they match the frequency the oil flows and it causes the oil surface tension to break... and miatas are known to chew rod bearings with aftermarket crank pulleys for the same reason. just a thought anyone running solid mounts?

the engine sits 2 degree tilted not enough to make any sort of difference. and the first time it was rod #3 ill know when i pull it apart if its the same rod.the first set of bearings were run for about 15 minutes and started making noise along with the head (there was a blocked passage in the head) i didn't pay attention to which bearing it was because I knew the head was the issue. everything mic'd good on the crank and i cleaned all the passages AGAIN got a new head cleaned it THOROUGHLY and put it all back together.
