Valve covers have been off. 273 adj rockers. valve springs, pushrods, shafts, etc all good.Time to pop a valve cover off
My guess is, you send a pushrod through the rocker arm
ticking,rattle,knock noise.Really can't tell, The ticking or the drone ?
Exhaust leak.
Ticking stops or changes when you let off the gas
Do you have a shroud?
Motor mount allowing too much movement fan hitting shroud????
It gets faster with engine speed. flex plate bolt? something on the accessory drive loose? I think the next question is "where does it sound like it's coming from?".
it sounds similar to when I had rod bearing failure a couple years ago. (2 rod caps were mistakenly swapped during assembly)
dropped the oil and cut open the filter. No metal found.
all rubber mountsTorque converter bolts and or dust cover are my guess without more info.
Is it solid or poly motor and trans mounts or still rubber?
I've had that happen.flex plate bolt?
backed the timing way off added octane booster and topped it off with high test. still doing it.Detonation?
Okay this might be in left field...but are you sure it's coming from the engine side and not something rattling in the interior/under the dash/window components/etc?
Few years ago my car had a nasty rattle, consistent with RPM but only from idle to about 2000.
I was going crazy trying to pinpoint it while it was happening....finally one day I went into the trunk with a flashlight and mirror, checking all the nooks & crannies. Wedged down on the sides of the trunk floor, down between the inner and outer quarter panel skins, was all this...
