So this is my 95 mustang Gt that developed a valve train knock. It comes from the rear passenger side valve cover. It had 2 bend push rods so I replaced the push rods lifters and rocker arms on the bent ones and I still get this noise...Ignore the variable Rpm's this is most likely due to the fact that a vacume house is not connected correctly.
If anyone is curious it was a rod knock and I put another 5.0 in.
