Wow! I had heard this forum was active, but what a response. Thanks guys. I'll try to get some pictures up soon. Just a quick update on what I've done so far:

~Replaced PCV valve (also cleaned out the Y-pipe it was attached to cuz it was all clogged up)
~Flushed radiator (it was surprisingly clean, but still had a little rust/funk)
~Flushed transmission fluid and replaced fuel filter (fluid was definitely used, but not awful. But man that fuel filter was clean as a whistle! I replaced it anyway since I already bought the part and was already up under it)
~Installed Sony 6x9 speakers in the rear (will definitely post pics of this ongoing audio project)
~Replaced factory stereo with new Sony head unit
~Got a key cast for the doors (owner who sold it to me had replaced the starter and had a key for that, but his daughter had lost the door keys).

Up next is replacing the spark plugs, wires, and distributor caps. Then buying an amp for those 6x9s (the head unit really doesn't push enough power to let those speakers realize their full potential). Then eventually addressing the issue with the front seal. The front seal replacement is going to take some time so I need to wait until I have a full day to spare, and between work and college I've had practically no time.

Finally, I have posted about an idling/coasting issue I have here:

If any of you are tech savvy on this and want to check it out and give me a hand, please do!

you also need to clean out the pcv line through the air cleaner housing, its square plastic molded in. ends over the top of the tbi.

Save your money. Don't put a $500 stereo in an $800 car.
Why not?
Because young people do not need to waste $500 on a car stereo. Spending as much on a stereo as you did on a car or a year of insurance is pretty damn stupid. Just trying to help him put his priorities in order...

... If you live in a dense area, like I do, it's a straight up, no bullspit, collision avoidance system. Bumper to bumper traffic or just hawkers at every intersection, they hear you before they see you. And when they walk up to my window to sell me stuff or beg donations... what?! Can't hear ya brah! :lol
Sure hope you have insurance that covers hearing loss. Driving around with such high decibel levels is going to have an effect on your inner ears' sensitivity.

(For reference, 85 dB is the level at which OSHA requires hearing protection. 85 dB is the level at which you have to start raising your voice to be heard when conversing with the person next to you. The higher the sound pressure levels above that, the less time it takes to cause partial or total deafness.)

If you carry passengers, or maybe you give that cute girl a ride, it gives them something to focus on, and keeps you from looking like a total cheapskate. My stereo will straight up pull your girlfriend out of your passenger seat and put her in mine... B-)

Insurance can be bought to cover your stereo, it can be pulled out in less time than it takes to get your tires mounted, and is safer than money under a mattress if you spend a lot of time in your car as I do.

So I have to disagree. :rasp
I'm going to look at an Astin Martin this weekend. If I buy it I will be paying cash. Nope, I think your girlfriend will be riding with me. She likes a man who saves his money and can focus on long term goals instead of one who buys stereo insurance. :D

Holy cow people. That escalated quickly :P From stereos to aston martins. Geez.
Well either way I appreciate the input. But yeah I'm going to be putting a good stereo in there. I produce music so a good sound system is extremely important to me. I'm willing to spend the money on it. And it's not like I'm going to go broke doing it, or spend inordinate amounts of money, or blow my ears with five 12" subs or anything crazy. Just something that sounds clear, loud enough, and with a little bit of kick on the bass end lol

By the way, it's Aston, with an O.

Here in Miami, stereo insurance comes in calibers... and being in the motorcycle racing field means I have girlfriends to spare. And they pretty much come with their own money. :D
You win...

To the OP, as far as your car and your stereo go, it's yours. Do what makes you happy with your car, but take the cautions about high decibels and hearing loss to heart. :thumb

While hearing loss is a possibility, quite often it's the distortion in the signal that is doing it. Sure, loud anything can cause it, but I use top notch signal processing and that seems to make all the difference. Been building car systems for years and so far, nothing noticeable.
That's quite the theory... "My real loud good stereo won't cause hearing loss like a real loud bad one will..." Ever run those theories by the medical profession? :dunno

IIRC, the eardrum does not distinguish between "distorted" or undistorted signals, the brain does. The "content" of pressure waves received at levels high enough to cause mechanical damage to the ear is pretty irrelevant. Of course, once hearing loss has occurred, research suggests that the actual clarity/quality of the signal does become more critical for using what's left. So all that high fidelity "wisdom" may actually pay off in much more meaningful ways later in life. ;)

I'm waiting for someone to be able to scientifically identify the "wife frequency" so a young guy can crank the eq UP on that one alone to intentionally cause real, physical, selective hearing loss (instead of the mental one we already have) in order to better prepare for marriage by getting a written excuse from a doctor that medically "explains" why we often don't hear what she says. :lol

If you're going to replace the front crank seal, then I'd suggest you replace the timing belt while you're at it. You have to remove the old belt to replace the seal so there's no extra work involved, and the belt is cheap (about $10 on ebay). Look at the crank pulley it should have 5 bolts, but it may have four. The belts are different, but most are listed as working on an engine with a specific pulley. Replacing the alternator/water pump belt is also a good idea at this time, since again no extra work is involved, and the belts are cheap (<$10 on ebay). Count the number of ribs (ridges) on the old belt to be sure you get the correct replacement. Remember your car's over 20 years old and none of the rubber bits may have ever been replaced. Another good (though more expensive) preventative repair you can make while replacing the seal is to replace the water pump. They do go out periodically. Replacement at that time requires only a little extra work and the pumps are pretty cheap ($20-$30). You can find instructions for all these little jobs here on the site. Advance autoparts also has pretty good prices on parts if you want to source things locally. Check their on-line deals. They often have $10 off of $50 order deals and such, and you can pick-up at a local store. Good luck and welcome. Oh, feel free to just ignore all us old farts arguing about stereos and such. We're just being ornery and cantankerous, because its fun (and not overly strenuous) to argue about things.

Don't know where you are IIRCing from... but I'm not repeating old shop installers tales. It's simple resonant science. The same reason clipping your subs and sending them distortion blows them is the same reason the tympanic membrane in the ear blows out.

If you really don't have anything better to do than sling pseudo science from recollection at harmless hobbyists with 500 watt stereos, perhaps you should take up a more daring hobby. Like underwater basket weaving?

:thumb

I've run several kilowatt systems using top of the line PRS equipment and Boston Acoustic Pro Series speakers, and my hearing is as good as ever.

Even if we disregard the fact that you slipped up somewhat and whipped out that tell-tale "home made rocket science" approach to "proof" that consists of "I do it/did it and nothing badhas happened to me therefore it must be ok" approach that screams "unscientific" and is an instant credibility killer...

I should admit, you got me. :D If you would be so kind to assist a poor dumb pseudo science slinger like me with no professional experience to the dangers and long term side effects of repeated exposure to high sound pressure levels, feel free to provide as many scientific references and published articles as you must have to support your position, and i will gladly be the first to admit I was mistaken about this.

I was IIRCing from prevous study of basic inner ear physiology and NIHL (noice induced hearing loss) because they were relevant to the last two professional careers I have been invoved in. My mistake to think what I remembered may be relevant or correct.

that "logic" fell out of common use in the scientific world say severla hgundred years ago, and unfortunately doesn't even rise to the level of pseudo-science that people like me sling around. :thumb

Oh, and those that know my professional background know I'm fairly risk averse, and manipulatively challenged, so even with several hundred dives worth of experience, I doubt I could handle the additional manipulative and mental challenge of adding basket weaving to that, so I'll have to pass on that thoughtful suggestion and stick to extremely boring .

Look forward to those scientific publications/references that support your theory, and thanks for your concern about my lack of scientific knowledge/method, and also you should consider contacting the scientific world about their obviously mistaken beliefs about NIHL. If you were to read anything about it, you would surely be the first to recognize the entire scientific community has obviously gotten that whole thing all wrong.

let me know what you think about all the published information you can find online about NIHL, ok? Or do we already have your answer to that knowledge base?

I'm not going to argue something that a child can research through Google in ten minutes on this new guy's thread.
Funny that's what I thought! I actually did take the time to go back and review the subject a bit to ensure I didn't owe you an apology for interpreting what you said to not be supported by most if not all of the basic available information on the physiology of hearing loss. :D

But if it helps, here is a start for you. American Hearing Research Foundation - Noise Induced Hearing Loss

Other than apologizing after you provide respected scientific/medical references that clearly show your position to be correct, I'll leave the thread alone and apologize now to the OP for getting dragged into something I should have known would just degenerate from the original mud-slinging/name calling you started out with.

And I hope that in spite of my sarcasm, I have tried to be somewhat respectful. I used sarcasm to hopefully infuse a little humor into my beliefs whcih conflict with yours, that's all. Being the old, ignorant, sarcastic, apparently dumber than a 10 year old, etc. (and I sincerely apologize if I left any insults you threw my way out!)... sometimes that goal escapes me.

I guess I could have just started learning about underwater basket weaving instead of actually re-researching something you initiated that to me seemed to conflict with and/or ignore everything I have ever read on the subject. It's just that when an old, ignorant, less internet competent than a 10 year old people with technical/scientific backgrounds that rely on actual published research to learn what those experts have to say on a particualr subject they are interested in learning more about hears (no pun intended) someone else who actually believes that the old "I did it and it didn't affect me in "x" way..." "logic" is some kind of earth shattering "proof, " it's hard to resist. :D

This has degenerated into a silly pissing match, but I do find the base question fascinating. There is no question that distorted sound is far more likely to cause damage to speakers or amplifiers, but is it also more likely to damage your hearing? I've never heard that before, but then again, I've never even considered it. I don't know how you would differentiate the fact that someone who has so little quality judgement that they would sit and listen to obviously distorted sound is probably far more likely to listen at insanely high levels.

The link that myredvert provided doesn't address this at all, they are using the word noise in a different way than a stereo aficionado would. It's proving a challenging search because every mention of hearing loss goes straight to "sometimes loss, sometimes distortion".
