Top end sounding rattle on my 01 Bullitt 4.6

[dviskoe]

hi all, looking for anyone who's seen /heard anything about possible valve train noise leading to issues on a 4.6

i've 51k miles on mine(some of those were put on 1/4 mi at a time), and it's started to rattle between 2-3k RPMs when accelerating.

ideas on what it could be ?

If I take off the valve covers will I be able to see anything obvious ??

any help would be great,
thanks

I've not tested to see if it !@#$% ing works yet though ...someone let me know,
also,
the sound comes over crappiely (it's word ...) but I do hear the rattle, let me know if you do / don't

Thanks !

bad news,
stopped by lincoln dealer on 61, just to have someone take a real life listen.
he's thinking it's bottom - end, prolly bearings. the way it knocks coming off of idle. ( and an exhaust leak too by the way, which I'd not noticed... but the custom exhaust hangs low and bumps on crap no matter how careful I am)
After Driving it awhile, I'm tending to agree. Bad ugly news for me though.

I'm eyebrow - deep in my '73 convertible restore, and do not have resources to dive into this right now. he really needs to make it through the summer (I've a bike and a truck to help with that).

If I want to just replace the whole short block, could I use this:

I'm *assuming* this is an alum. TEKSID block, correct ??

thoughts ?
input ??

That towncar motor will be an iron block. Should be the same shortblock.

Can't hear the noise in the video....

It might be the timing chain guides...

I find it hard to believe that it would be bottom end noise only at certain RPM.

going to put in this:

as a long block,

any advise for pulling that engine ?
separate trannie 1st , or puill them together ??
where do i chain to ???

what don't I know that I should?

... any volunteers to help out for a bit sat. ??
I pay in beer !

The set up can come out together but its a pain in the ass without the correct tools. What am I saying, its a pain in the ass with the correct tools, but its possible. I've dealt with a few of these and would be more than happy to take a look at it for ya if you can get it to me. Don't just take a dealer's word for it that your bottom end is shot. Always get a second opinion. PM me if you have any other questions.

pm sent ...
i'm all about 2nd opinion!

You second long video clips did not have any good audio. Does it sound like this crapbox? http://youtu.be/SiXzMNclvxQ
A good audio recording might help, or better yet a personal look from a TCS expert. I've delt with a couple of timing chain issues on the 4.6 (both pickups) and both were not a terrible fix, didn't need any special tools. Cloyes makes a good set. Goodluck.

[dviskoe]

Yes, not quite that bad, but thas it, Ibelieve

[CS]

does it make a boom boom bang ding or just ding ding ding ?

[dviskoe]

Not as high pitch as a ding, not as loud as a boom, more of a thunk?!?
Not as loud as the other video though...
