Im not too keen when it comes to heads and their parts, is a valve guide the same thing as a lash adjuster? I google imaged both and they look exactly the same. Im starting to think the noise or "rattle" I hear from 3000 to 4000 RPM's when at cruising speed is either or, but oddly enough I dont hear it when throttling through at a quick pace...thanks!!!

HurrycaneStang · May 16th, 2011, 06:05 PM

Im starting to notice they are different and have different purposes lol, so any idea which might be the culprit?

SWEET2KSTANG · May 16th, 2011, 09:13 PM

guides are powdered medal stock or aftermarket bronze. this is what holds the valve and tolerences are crucial in life of the valve. lash adjuster is little black cylinder thing with adjustable piston. it is on the other side of the follower.

as for your noise, if it were an adjuster, the noise would generally be there all the time no matter if you at idle or WOT.

HurrycaneStang · May 16th, 2011, 11:08 PM

yeah, I got a chance to pop the hood today when I got home and listen to it, its kinda odd, it doesnt make any more noise than most 4.6L do when revving it up in the driveway, but when i took it around the block I can hear it again between 3000-4000RPM, im starting to wonder it has something to do with the drivetrain? The guy supposedly put in an aftermarket clutch/flywheel right before I bought it and it has an aftermarket short throw in it as well...

Lefty · May 17th, 2011, 12:16 PM

Maybe a throw out bearing. Press the clutch in and rev it up to 3-4k. Does it go away?

HurrycaneStang · May 17th, 2011, 01:03 PM

yes

... well a lot more than if im in gear...

Lefty · May 17th, 2011, 03:08 PM

So the sound goes away with the clutch pushed in?

HurrycaneStang · May 17th, 2011, 04:37 PM

I dont hear it unless im in any gear and between 3-4K RPMS and at cruising speeds, but if im in neutral and rev it up there I dont hear it, also if im in gear and with heavier throttle through it I dont hear it as well, sorry, I dont know how to word it exactly lol

HurrycaneStang · May 17th, 2011, 05:15 PM

So researching a lil more into it, I found out alot of people suffer from "shifter noise" whether it be from the aftermarket hurst shifter or my Steeda Tri-ax shifter, I found a link to this guy that makes shifter gaskets and it supposedly cuts out like 95% of noise, im really hoping this is the issue, im gonna pull the boot today and listen to it, does anybody else have shifter noise?

Lefty · May 17th, 2011, 07:13 PM

Cobra Bob's gaskets? lol, from SVTP...

HurrycaneStang · May 17th, 2011, 11:13 PM

Lol yeah, its only 10 bucks so we'll give it go and see how it turns out

Lefty · May 18th, 2011, 08:55 AM

It's a good product.

HurrycaneStang · May 18th, 2011, 10:42 AM

Im gonna look through the forums and see if i can find somebody that bought them and made a thread on them, im crossing my fingers that this gets rid of the noise

Lefty · May 18th, 2011, 01:43 PM

It's cheap. It doesn't hurt to buy it anyways...

HurrycaneStang · May 18th, 2011, 10:49 PM

Well Friends, Im really hoping its just my shifter rattling, but unfortunatley preparing for the worst, it might be a spun rod bearing

I found this video and it sounds almost indentical to my issues, and it happens at 3000 RPM's only....fuck my life, at least I have a spare Mark VIII motor lying in my garage maybe I can reuse some of its parts or use what I get from selling my 98GT and just buy forged internals....

HurrycaneStang · May 19th, 2011, 10:25 AM

the only thing different is, you dont hear mine until 3K

HurrycaneStang · May 19th, 2011, 09:32 PM

Okay so I got a video of my actual car, its kinda hard to hear unless your volume is up high, so maybe the noise is originating near the shifter? If it isnt good enough sound quality let me know and ill re-do it, thanks guys

04GTAMPA · May 19th, 2011, 09:39 PM

I want to rule out the spun bearing. Does it change when the engine is at different temperatures? How's your oil level?

Do you feel it in the shifter? Try to feel it by the feeling the noise to a "tap" on a rhythm pattern in the shifter.
