This is what happened when I put my roller rockers in, and after I let it run for 5 min to let it "learn". Anyone had a 3.0 that sounded like this after? I like how it sounds - (I know that's not how it's supposed to sound) - in the back but it's got a BAD shake and it idles low. Could I have tightened a rocker too tight?

 

sounds good, but did you mix up your rods? seems like the valves are opening / closing at the wrong time

 

the exhaust sounds damn good.

 

No, all the pushrods are the same length. I don't know what could be up with it.

 

ha, thats a mean *** sounding 3.0


but sorry, i dont know how its supposed to sound

 

And yeah, the exhaust does sound good, but the thing has the shakes like a chihuahua passing a prune pit . I have no idea what it could be that's making it do that.

 

is it cat-back or full exhaust? sorry to steal the thread, just the best sounding 3.0 i've ever heard and interested in the same setup.

 

CEL on? I dont think it should sound that lopey, but who knows.. wayne or fred should be able to tell .

 

i dont think "dead"s truck sounded like that.. well as lopey or w/e


he has the rocker rollers too

 

lol, It's stock back to the last cat, that one is gutted, then a si/do Flo 40 into 4" by 18" stainless rolled tips.

I don't think this is how it's supposed to sound when I just changed to roller rockers, but I'd be fine if it kept the sound coming out of the exhaust, just not the roughness in the engine bay.

This is how it sounded with ^that^ same setup minus the rockers, coil pack and wires.

 

The CEL I think is an old code I haven't cleared yet (misfire) when I got the coil pack wires mixed.......oops

 

have you given it any gas or driven it to let it really reset itself?

because when i put my efan on the engine was idling funny(not that bad though) but after a quick drive it got better.

 

word, thanks for sharing. back to the rockers.

 

I gave it an easy rev up to 2 grand but it didn't want to go there very easily, was super sluggish (almost like a miss) but no backfire, sputtering, or surges. It wouldn't crank a minute ago, I finally did get it cranked after pumping the gas while starting.

 

See, that's whats aggravating me, I didn't unhook the coil pack, I left it just how it was before (it ran great then). I even traced the wires to the right cylinder to make sure.........Something just came to mind, is it possible to "break" plug wires, like if I bent them?

 

yes

 

Hm........Maybe I yanked a little too hard on 2 of those wires attatched to the back of the valve cover. D., when you said "2" it flashed a clip of me pulling 2 wires to get that "clip" off of the back bolt. It holds the plug wires and clips on a valve cover bolt in the back and one wire had already come out. I'll have to try changing out those wires in the morning.

Anyway to "feel" or "see" if they are busted?

 

i have roller rockers and it doesn't sound like that. my engine sounds much smoother than before the rr's. i had a faint ticking noise when i first started it but it quickly went away. are you sure you followed the tightening procedures correctly? i know i had a little bit of trouble figuring out top dead center.

 

Pretty sure about it. I'm having it double checked tomorrow by a mechanic who lives across the street but I'm pretty sure. Both valves closed, tighten till push rod don't move up and down but can spin freely, and one full turn after that for the .042 preload.

 

Problem solved!!! The #6 cyl. intake valve was too tight, therefore always open. Tore the intake and valve covers off and re-adjusted all the arms and it ran fine.

 

glad you got it figured out.

I hate messing with a daily driver, something is bound to go wrong for a week or so.

The original video is nice. Sounds really good if you had a cam in it but when you find out its stock . . . Reminds me of the old "pull a spark plug and vacuum advance" trick.

My 66 falcon (when it had the 200 inline) sounded a lot like that at idle with 5 cylinders

 

glad you got it fixed,I thought it sounded like my old V8 when the timing was off.

 

How does it run now that its fixed? More Power? what range? gas mileage differences?

 

Eh, to be honest I feel little to no change. Just a tad more torque, I know that because I could never accelerate in 5th gear- it always downshifted -and now it'll slowly creep. But with my jump in the truck and romp on it test-drive, I felt no difference. Even after I let it "learn" to work with the new ratio I still can't feel it now. My rev limiter in P and N is bumped to 3,250 rpm instead of 3,000 and it's quieter in the engine bay, but that's it.
