just want to make sure its rod knock before I drop the pan. its a z24i motor. There are no metal shavings in the oil so thats why I wasnt 100% on the rod knock.
Sounds like an exhaust leak to me, but I don't hear so good anymore.
Check your valve lash. Sounds like that. Doesn't get louder under load only speeds up when revved
Rods before they are totally trashed, tend to make louder sounds under load or suddenly letting off on the gas.
Exhaust leak is always louder under load.
like if im driving and I with the windows down i can hear it at idle but i can not heard it while driving at speeds
Get a couple of wrenches, a screwdriver and some feeler gauges. You've nothing to loose doing this and if the rod's fucked this won't hurt it. 😄
Warm engine thoroughly and set engine to TDC compression on #1. Take valve cover off and quickly adjust both valves on #1 to 0.012'. Adjust the intake on #2 and the exhaust on #3.
Turn the engine exactly ONE turn to TDC and adjust all the other valves not yet adjusted.
You should easily be able to complete this before the engine cools. Beats bumping the engine over... and over... and over.
