94 3.0 V6 ticking/nock sound through RPM's
Its not very loud but always there, i did search and the only thing i hear is timing belt. anyone ever have lifters get a little slacked? i hear they are hydraulic, but it sure sounds like lifters. anyone out there with any tips? i'm gonna read through the haynes manual tonight.

The 3.0 is a noisy engine, usually a little noise is nothing special, just the sound of gas being guzzled

My 3.0 did this ever since I got it with 100k miles. It even got a new shortblock, adjusted valves, plus the timing belt and waterpump replaced, however it still ticked. It is just normal. My 3.4 has this same tick, but I am pretty sure its just the vsv for the emissions. If you search for "ticking" you will find a lot of info.

check for exhaust leaks as well, I had a very small leak in the pipe near the manifold. i could only hear it under acceleration. made it a real bear to find in the driveway! (it made an almost clicking sound, like injectors/valves)

Oh well, live and learn I guess!I might look into that firewall plug just to quiet things down in the cab.
