Hey people...... it's a 302 with EFI.
I've wondered about some strange engine noise since I started driving this
car (about 2 years now). My household has had the car for 18 of it's 20 (or
21?) year life...(parents bought a month before I was born).
First time I heard it I freaked.......told my dad about it. It's a
staccatto clack sound....almost sounds like rockers makin' noise.....it's
proportional to engine rpm, but I really don't hear it as much at higher
rpms (I barley, if at all, hear it at high speed idle, but when it kicks
down to normal, it appears, and at gradual throttle increase, the sound
level of that noise decreases).....mayber just cause the exaust and all the
noise in general is louder.....
My dad said it'd been makin that noise ever since they got it, he never
figured out what it was. We'ver had any trouble with the engine before,
other than some crap getting stuck in the EGR valve holding it open. The
water pump has probably been up 3 or 4 times. We've inspected under valve
covers. The thing runs absoloutly great, I can totally step on it and make
it to 60 in a little over 14 seconds (woop-te-doo....), almost no
pre-ignition, and I put 87 in it. it has about..... 135,000 miles on it (I
know not that much!...small town). But it just bugs me!
Anyway, if anyone has some ideas on what this mysterious sound could
I agree - my '84 T-Bird (302, CFI) had a similar noise. It was especially
noticeable when just taking off from a stop(relays and vacuum solenoids
clattering). I got to the point where I got nervous if I didn't hear it
because it meant something had come loose or failed. My '84 also had what
seemed to be rod knock when first started each day that went away as it
warmed up. I gave the car to my best friend with 184,000 miles on it and it
is still going strong.

The solenoid that operates the EGR valve makes a very noticeable staccato
racket and does vary a bit with RPM. It quickly energizes and then lets go
to vary the amount of vacuum to the diaphragm on the valve. At higher speed
and RPM, it is mostly open so less noise. Mine was located on a plate that
had several others and sat under the coolant recovery tank in front of the
driver. The noise traveled back thru the inner fender. I was always told
it was a noise only "car nuts" could hear. Welcome to the club!
Well thanks for the welcome.....and I think I'm not just a car nut......but
a nut in general....lol.... most of my "peers" (I'm 18) make fun of me for
what I drive, and the fact that I like the car (these are the kids that are
mostly all spoiled with their brand new (or mid-late 90's cars) and really
don't do anything but drive them. (uh oh, here comes the life story of the
car and I...)
A few months after I started driving the car (16 yrs old), one day I was
driving to school, and I saw the school bus comming the other way and I knew
it was about to stop, so I just floored it in hope to get by....and I heard
a big boom. Needles to say It scare the sh** out of me. Slight releif came
when I realized the engine was still running....and the exhaust was
extremely loud. I got to the school parking lot and looked.....muffler blew
up. So a couple of weeks later we had dual exhaust put on (true dual....).
Then about 6 months ago the air pump started makin a lot of racket....so we
took that in fear of it locking up, and since that came off, might as well
cut off the cats......(don't tell the epa!). Now the thing sounds pretty
good. Not too loud, not too soft.
Also last summer it had its very first radiator transplant. Also took off
the water pump and cleaned it up, and sealed some bold holes that we
suspected were leaking. It doesn't leak nerly as much coolant now :-D
Also in the life of it, there've probably been 6 master cylinders, 6 power
brake boosters (UHG!). Done full brake systems once or twice.
And the most fun came a few weeks ago, a friend of my dad had an 83 grand
marquis LS (yeah yeah, mine wasn't an LS...) But his engine croaked and was
going to send the car to the crusher, he said we could take what we wanted.
So I got the LS seats, I pried every emblem off the thing, I have a spare
grille, Tail lights/lenses, spare steering wheel, power antenna, all the
power lock/window motors & Mechanisms, door pulls, arm rests, cornering
lamps, tone generator (this one worked a little, which I fixed and made it
work like new!), fuse panels.... The list goes on and on......even a few
things that I didn't know what they were. Not often you get a nearly
identical car free for the taking. The only thing I"m dissapoined
about....the guy kept his nice aluminum wheels... :-( and put then on his
trailor. Ah well, can't expect too much for free...
We also have a '92 grandmarquis (LS I think...it lives some where else right
now), '90 accord ex, '79 F-100, and '66 Thunderbird.
Well, that's my automobile nerdism in a nut shell. If anyone even read the
whole thing.....Hey I'm also an electronics/computer nerd! Yahoo
Anyway thanks for the advice on the noise...hehe
Nice collection and a great friend! Those parts will keep you going almost
forever. I have driven mostly T-Birds but am selling the only one I have
left - my 1967 UNrestored one. I drive a '95 Crown Vic right now. I like
it because it doesn't scrunch me up like a lot of other cars do. It's fast
enough for me and stops quick. Of course, the nice Hi-Fi I put in helps
