Cleaning up the engine bay (removing stuff)

Hey everyone. I just got my first job at a dealership (huzzah!) so I now have the funds to start fully restoring my Firebird. I wanted to know what I can remove from the engine bay. For reference, it is going to be street legal. I live in New Hampshire and the car is 22 years old as of right now, so I do not know what laws it must meet.

But I want it to look nice and clean and be easier to work on...less stuff to break...ect. Are those clean stripped down bays just for non-street cars?

Re: Cleaning up the engine bay (removing stuff)

theyre for non emissions cars, if youve gotta run a smog test i wouldnt bother. I yanked my smog pump and got a different belt to clean up my engine bay a bit, but then you run into federal law stating all vehicles must retain factory emissions equipment

keep in mind the more you strip the more "comfort" features you lose, you pull the AC stuff, you lose AC in your car etc

Re: Cleaning up the engine bay (removing stuff)

well here in johnston county, nc on anything older than a 96 model I don't have to deal with the emissions I have to keep the CAT but as far as anything under the hood no one even looks they say that you're supposed to have a muffler but none of the shade tree inspectors check or even care just give them their $13.75 and leave.

with that said what can I clean up on my bone stock 89 rs? or does the computer still need everything that is there?

Cleaning up the engine bay
removing stuff
Those are 2 very different things.

The first is done at the quarter car wash, then perhaps in more detail with a rag or sponge. It is done by people who want their cars to work right and be dependable, and who take pride in caring well for them.

The second is typically done by ignorant people who (a) can't assemble a car sufficiently well to where they can just DRIVE IT and LEAVE IT ALONE and don't have to fiddle with it constantly; (b) are clumsy and careless; (c) are ignorant, so they don't know what any of that stuff does and don't care to find out; and/or (d) don't understand that NONE of it has really ANYTHING to do with why their car isn't fast. So instead of calling what they're doing by its real name, which is HACKING, they substitute... that other phrase ..., that makes HACKING sound like something positive. It's not.

So in short:

clean ... bays
are for any kind of car. Similarly,

stripped down bays just for non-street cars
is a pretty good description: they're either for purpose-built race cars that need to have as little as possible extra weight that doesn't directly contribute to winning races, or for cars that spend alot of time on cinder blocks. Since it doesn't sound like your car is destined to be either of those things, I'd avoid getting infected with the misguided idea that hacking parts out of your car is somehow an inherently desirable goal.

Besides, the only people who would have the slightest interest in finding out what's under your hood, can't see through your back bumper as you drive off and leave them, anyway, and probably wouldn't understand even if they could; because there's a good chance they're the type that hacks off everything in sight for no reason, and that's tied in with why their car is slow. Now granted, I've only been in this hobby for 35 or 40 years or so, so I definitely haven't seen "it all" and I know I have PLENTY left to learn about it; but in all this time, I have NEVER ONCE found a correlation between a car being desirable (fast, reliable, economical to drive, etc.) and having a clear view of the castings while it's sitting still with the hood open. In fact, seems to me, the correlation is usually the OPPOSITE: the ones that are missing their A/C and accessories, are usually the ones whose owners are complaining about stuff not working, have leaks everywhere, can't drive on a long trip (say, 15 miles or greater) without requiring someone getting out and fussing with something under the hood, and so on; whereas the cars that are COMPLETE but CLEAN are usually the ones you could walk out to the driveway, turn the key, and drive from coast to coast without doing anything more to them than putting in gas every few hundred miles and oil every couple thousand, with the A/C blowing cold and their female companion with them and not griping about the noise, filth, heat, vibration, and all the rest that goes with hacked-up junkers. Between those 2 types of cars, which do you want yours to be more like?

Re: Cleaning up the engine bay (removing stuff)

Alright so now that the preaching has been done you can remove your smog pump, you can either get a delete pulley or re route the belt using an 89ish s10 belt with ac, kinda tight but it fits. If you wanna nix the ac you're gonna need a pulley for that, you can reroute the cooling lines to get rid of the bassackwards mess from the factory I haven't don't that one myself but apparently you can simplify it a lot and ditch the metal cooling line etc

The only thing the ecm is really gonna need is stuff that's plugged in, except like the ac and smog pump, if it looks removable go for it but just be cautious and watch your ses light for a few days

Re: Cleaning up the engine bay (removing stuff)

how much do you like playing with wiring?
you can always reroute the harnesses to be more out of the way, remove the heater diverter valve to eliminate a hose (and the valve)

-depending on your emissions, you can go to non-smog headers and get rid of the air pump

-if you don't care about ac, a non-ac box will open up a lot of room on the passenger side and the compressor & hoses can be taken out too

Re: Cleaning up the engine bay (removing stuff)

Yea sofakingdumb...um, I just wanted it to be a little more organized and cleaner like the ones at car shows. Please don't lump people who don't want a bay full of wiring as dumb hicks who are trying to save weight. Thanks.

Re: Cleaning up the engine bay (removing stuff)

Look around on the site I have seen some sensational engine bays on here. Stuff I drool over. That type of bay though will require a complete tear down some body skills, and being handy with the paint. If you just wanna get rid of some engineering stuff that only works on well cared for cars and ultimately will not do you much good unless you are in one of the lucky states that require an inspection look closely at this and some other cars. The air pump is a failed idea, it can be removed, replaced with a non air cat, and the car can be tuned for better efficiency assuming you have TBI or TPI. As stated before the Heater hose routing can be moved or all together simplified. Why GM left it hangin over the valve cover with no support seems pretty bonheaded or lazy to me. The harness in the engine bay is atrocious, but it takes good documentation and some know how to get that moved correctly. Here is my attempt at cleaning a mess, who knows it may be more messy, but I like it.





The work here is probably not noticeable, but it did all of 2010 Power Tour, many people mistook it for stock, which is cool by me :-)

Hey is that your coil mounted in the back kinda hangin down? If so mines stock but I want to mount it somewhere else off the intake manifold. Where did you get that carb hat, that setup rocks little $$ for me, but if I could find the hat I could run me some cheap piping.

Re: Cleaning up the engine bay (removing stuff)

Dude I ripped my complete smog system out, I even plugged my exhaust manifold holes were the piping came out. I cut and closed the pipe that went down were my cat used to be. PLated my egr valve. Relocated battery to the trunk. Completely removed cruise control including wiring and hose, frees up a usable gromment and hole. Pulled my charcoil canister. Removed the diverter valve for the heater and rerouted simplified the hoses. Removed the stock wiper fluid tank and overflow tank. Going to replace with 4th gen ones there hidden under battery tray and in the fender. Read a article on it. I also pulled all wires rerouted simplified them. Moved all relays to the battery location. I tried to hide most wires. Everything I read was on here, but the wiring is a huge headache so be prepared and try to cut as little as possible and if you do cut, fix correctly. Also the smog argument, there isnt one,rip it. But the egr seems a little split on here to block or not to block. But like mentioned those systems only work when in working cond. these cars are old most are clogged not working correctly are not at all. I just feel sorry for those in cali. there screwed with the strict laws. Lastely if your gonna pull stuff, take the time to pull it 100% do it right. Dont pull the pump but leave the plumbing, same goes with the a/c. Have fun your engine bay will look b#$chin.

Re: Cleaning up the engine bay (removing stuff)

I really like your bay, that's what I'm going for. In class we were going over state inspections with a state trooper and I asked him about our state laws for removing stuff he said if it came factory it needs to stay there regardless of whether it's being tested so :/

Re: Cleaning up the engine bay (removing stuff)

technically. not actually. IF a cop wanted to be a real jerk he could hit you with a ticket for tampering with federally regulated pieces...

however in the real world unless he is tearing your car down youll never have an issue with it, ive been pulled over god knows how many times and only 1 asked me to pop the hood, but he was just being cool and talking about the camaro with me lol

go for it, just keep the parts that way if you need to put them back you can

Your completely right most dont notice are care, but thats why I felt the need to do everything 100% that away if someone did look, and didnt know exactly for what they wouldnt notice anything. But if you have pluming going to nothing and theres a huge gap in the bracket its a dead give away. I even contimplated cutting the bracket but I feared it my be strained by the a/c compressor or something. You know because those brackets are so soft. Ya and like he said keep the parts I did, but my tubing for the smog system is ruined I got frustrated an had air power tools.

If your car is a bad *** restore, or in really good condition and everything is working the way it should, than pulling stuff is in vein. However these cars are old and alot or way beyond peoples wallets to restore or fix. You know theres a thing called dominishing return(you wont get out of it what you put into it). So pulling useless nonworking crap isnt such a big deal. If you have t-tops and your vehicle isnt your main sorce of transportation, what does it hurt to pull A/C crap. If your emmision stuff is no good, clogged not working. Pulling it would probley save you gas, car would run better which is better for everyone. I pulled my cruise control, I dont even know if it worked ive had the car for 8yrs, so obviously I didnt need it. I mean its not a Lincoln Town car, its a Camaro!

Also for most there camaros are there weekend warriors or 3,4 vehicle like me. Not there primary source of transportation. I guess the guy who removed the A/C and left a open hole in the firewall or the guy who pulled the smog crap but didnt pull plumbing or plug holes change belt. Those people would need a talking to I guess. Are the guy that cut the wires going to those things, are left them hangin.

The A/C was already off the belt when I bought the car, leaving it there was pointless. I was going to do that, anyway. If I don't use A/C...why have it in there. The whole A/C system and EVAP system does clean it up a bit when you remove them, I like my bay more already. The 305 is coming out next week, I will be cleaning up everything, painting it, and probably seeing how many wiring harnesses I can bundle and tuck away. I'm not sure why that guy thinks I'm gutting it out, but there is no reason to not have a cleaner engine bay...

Re: Cleaning up the engine bay (removing stuff)

The carb hat is an old ATI procharger hat. It is the best flowing low profile hat I could find.

I guess the best advice I can think of is the following. As you remove devices and systems, your best bet for success is to understand what they do and how they affect your vehicles operation. It you can improve, replace, or remove that system without negative effects to other systems than go for it. If you cannot you need to understand what the drawbacks are and how you plan to use your car.

The most visible example on my vehicle is the PCV system on my car. As you can see it is modified with the Moroso catch can. The new system helps eliminate intake mess at extended RPMS over 6K

Re: Cleaning up the engine bay (removing stuff)

On mine, I removed the AC, smog pump, heater diverter valve, cruise control, EGR, and all the related wiring, along with the huge ugly coolant and washer tanks. I have also relocated the charcoal can behind the front bumper.

I have T-tops so I'll never use the AC, not that I would have anyhow I hate it. I have always preferred having the windows down and the fresh air blowing through my hair.

Cruise control I don't use since I don't spend hours on the highway every week.

The AC and smog pump were also disabled when I got the car. The smog pump was missing the tube to the cat and the bearings were going bad anyhow.

The AC condenser and lines were destroyed when the PO wrecked the car. The diverter valve was just ugly, and 2 heater hoses is a lot easier to reach around on the passenger side.

The EGR was not needed once I swapped in the carb'd V8.

As for the pulleys/belts/accessory mounts, I have only an alternator, power steering pump, and water pump running and only have the brackets and belts(v-belts for now) mounted.

I know what all those systems do/did and I am perfectly happy living without all of them.

The coolant and washer tanks were replaced with a single combination tank from a Ford Explorer, mounted across from the battery. I think it makes the engine bay more "balanced" visually.

All the "extra" wiring was cut where it comes through the firewall/behind the passenger fender, with the ends folded over and covered with heat-shrink tubing. The few wires I had to shorten or lengthen were soldered and wrapped with heat-shrink tubing. I even installed an extra fuse box near the battery to accommodate the extra electronics I have added/plan to add to the car instead of trying to splice into the fuse panel under the dash.

Everything I have removed also makes it much easier to reach things in the engine bay for cleaning or if maintenance is needed. I DD my Camaro from May to November every year since I have had it. It has never given me any major problems requiring me to perform emergency maintenance on the side of the road. If things are removed properly and correctly, then the car will run normally and with no problems.

In the future I will be relocating the battery to the trunk, moving the washer/coolant bottle under the battery tray, hiding all the wiring and relays in the engine bay, removing the heater hoses/core(have to leave the blower motor since a working defroster is required to pass inspection in PA), and swapping in a serpentine setup from a G-series fullsize van.
