RE: unknown noise

can you narrow it down a little more? Speedo cable wouldnt sound like it was comin from the vents on the passenger side, and and exhaust leak would *probably* get louder as you accelled. sounds like sticky lifters- seafoam is your friend, even if its not the problem, its always a good idea to burn the crap out of your engine.

RE: unknown noise

i still have the smog pump, but the tube going back to the exhaust it cut off and just hanging back there, could that be whats making the noise becausei think my air pump still works.

ill probably seafoam it because ive been meaning to do that anyway. And i know its now the oil, because i change it religiously

thats exactly what i think it is....the pump is pushing out air and the pipe that runs to the LH head is pushing out air....i had the same problem...i thought i had an exaust leak....i crimped the tube in the back and the noise went away
