Ok I had an exhaust leak that was causing a chattering noise at high rpm's. I finaly found it and it was a missing header bolt on the back passanger side so i put Stage 8 locking header bolts all around. i also replaced the oil sending unit and spark plugs while i was at it and now when i put my car under a load there is a BAD chattering noise at about 3500 rpm's and up.


Dose ANYONE have any idea what this could be????

 

So. No ideas

 

Did you replace the gaskets when you did the bolts? Where is the sound coming from?

 

hows your oil pressure?
