Engine maintenance help pls

Hey guys,

i got another set of Q's, lol. Well I've got my new job, and i'm driving like crazy. I deliver checks to my employee's all over the place plus my commute from and to work is about 60 miles all together in heavy traffic ( I live in LA and have to go through downtown LA at 5 pm, sigh, jesus, gd, o well lol!)

My engine is dirty and full of dust. Its completely bone stock and I would like to know if any of you have any recomendations for a few upgrades that will help with gas issues and how best to clean it with out damaging any electronics in the process!!

I've already put NGK iridium spark plugs, i should do the wires but don't know which? I don't need anything performance just something that'll give me the best spark and help with wasting fuel that isn't burned up due to lack of ignition... would a better air filter ( a k&n) be a better choise than just a new TSP filter? or would that just make me waste more gas? again I'm not trying to squeeze out any horse power, just trying to save gas, lol.

On the cleaning issue- i've seen a setting at car washes that says "engine" and refers to engine cleaning, how does that work if anyones done it?

I've heard i can crack the block if i take it to a car wash and spray the engine down

My idea was, let the engine cool for a few hours, cover the distributor, battery, alternator and fuse box and then spray the entire thing with an engine degreaser, let it sit for 10 min or so and then spray it with the pressure washer at the car was( that shoots water) or is the "engine" setting a special solution that won't harm your electronics?

Thanks guys :_)

I found this and thought we all might benefit from it :)

Many car, truck and RV owners spend hours cleaning and waxing the exterior of their rigs, but do not give any more attention to things under the hood beyond checking the fluids periodically. There are many reasons why it is important to clean the engine and its surroundings routinely. A clean and tidy engine compartment makes it much easier to detect oil and fluid leaks, damaged or worn drive belts and rust or battery corrosion before they lead to more serious damage. And if things really get out of hand, the dirt could provide fuel for an engine fire.

Cleaning the engine compartment is not that difficult and unless you are a perfectionist or plan to enter the vehicle in Concours d'Elegance competition, it does not require much elbow grease.

First, warm up the engine for a few minutes. This will help soften the grease and crud. However, do not let the engine get hot. Never spray water on a hot engine since sudden temperature changes can cause serious damage. Also you can get serious burns from hot engine parts.

Next, cover critical parts of engine with plastic bags and rubber band to protect them from water and other liquids. Either cover the air intake and filter or remove it and cover the opening. Protect electrical components like distributor, coil and fuse box. Use rubber bands to seal the bags around the components. Check the oil filler cap, the power steering filler cap, oil dip stick, etc. to make sure they are tight.

After everything is sealed up, spray the engine, accessories and surrounding components with a high quality non-petroleum-based degreaser that will not harm the paint. After letting the degreaser work for about five minutes, use a soft brush, a paint brush works well, to loosen up the crud. Respray with degreaser and rebrush if grease and grunge remains.

When the entire engine and engine compartment looks pretty clean, rinse with lots of water from your garden hose. If you can, hook up to a hot water tap since hot water will do an even better job. Better yet, do the job at a do-it-yourself car wash which usually has higher pressure hot water and is set up to handle the dirty water in a more environmentally friendly way. Even though the degreaser may not contaminate the ground, the nasty stuff washed off can get into the groundwater supply and do harm. Many car washes have equipment specifically for cleaning engines. If you want to use a degreaser that you know is safe, I only use the facility to rinse with plain, hot water. Clean the engine first and wash the vehicle after cleaning the engine compartment making sure all overspray of the degreaser is removed. Since all degreasers will remove wax, plan on rewaxing after cleaning the engine compartment.

Once the engine and compartment is clean, immediately remove all plastic bags and rubber bands. Dry standing water and aluminum parts with a soft cotton towel. Start the engine and let it to warm up to dry the rest of the engine as well as evaporate any moisture that may have collected in electric parts. If you do not start the engine immediately, often moisture will seep inside parts and it now will take a long time for things to dry out. If this occurs, use an ordinary hair dry to heat ignition systemparts like distributor and coil.

Once everything is dry and has completely cooled, you may want to coat hoses, weatherstripping, shields, gaskets and other rubber parts with a rubber protectant. However, do not use it on rubber belts since it could cause them to slip.

I like that article you put in here. I'm gonna have to do that before the big meet. Anyways, with the air filter, a K&N would be a good idea, unless of course you wanna get a full intake (cold air or short ram), which you don't seem to wanna do. I had a K&N filter in my old car and it made a marginal difference, but a difference nonetheless. Also, if you go with the K&N, you won't have to keep replacing it as you need to do with OEM filters; just remove it, spray it with a high-pressure hose, and re-oil it (K&N makes filter recharge kits with the proper oil to use when reinstalling the filter). Good luck with everything. Hope it all works out.

P.S. I'm sure this isnt the case, but if you got a lude to save gas, homeboy, you got the wrong car. Haha.

Ditto, K&N will definitely help marginally, and eliminate future replacement filters. You're doing good with new spark plugs as well. Make sure the fuel filter has been replaced at proper intervals. Try adding some injector cleaner and such to your gas. Only use quality gas, Shell has plenty of detergents in the gas to help keep all the gunk build up on the valves down as well, always good.

As far as cleaning the engine you pretty much nailed it. Spraying down a hot block with cold water could definitely crack it... or warp it. Combustion temperatures inside the cylinder are immense! Think about throwing ice into a hot drink.. it cracks instantly. I covered up all the electrical components and shot it down with the degreaser a few times, and rinsed with a hose.

Yeah I kind of put my foot in my mouth on the gas department- when i researched the car the review said it got 19.4 city and 23 highway. which isn't too bad, compared to my 8 per gallon on my 500hp mustang =\

I've always liked this car though, and its not like i'm doing "super" bad on gas- i just wish i had a hybrid, LOL! i hate those 25 mpg bastards, lol. But for as nice a car as this is-looks, performance and style, its good on gas, but every bit helps, specially when i sometimes drive over 100 miles in one day

I put a fuel/carburator cleaner a while ago and it seemed to worsen things LOL my gas seemed to disappear- the fuel filter i haven't done- i don't think i want to, i'm hoping for partical cloggage :P LOL! jk

I need to do my timing belt cause i have some oil leaks and i'm getting the kit so those'll get fixed- I think on these cars, and no offence to those who have, any power upgrade in the end is just another expense with little results...i got an sh, rated at 195, thats like 160/170 to the ground after drivetrain loss, even being that they're front wheel drive and not much is really lost since the damn thing is fron't wheel drive....but a cold air intake, with out header and full exhaust upgrades and a bigger/ported throttle body won't really show much power, specially if you don't do any tuning

To me the car is super slow until i crawl it up to over 100 and hold good rpm's then its a fun car to be going twisty turny...other than that under any gear at low speeds it has no torque, or atleast i can't feel it- but being that preciously i was strapped to a rocket it might be a while before i readjust to regular acceleration lol

But I am extremely happy with my prelude- i love the color( ucalyptus green!) its sessy! drives really really nice and smooth and i think over all its a good choice on my first import =)

I'd love to fix it but i'd have to put some real money on it to get it to where it would be acceptable for me, power and looks wise...doesn't it just look great stock though? Get an inch drop on the front and a thicker walled set of wheels for the back and you got a crazy nice stance...oh who knows lol i better shut up before i get ideas lol

You could try one of those tornado things you know the ones on TV. I've seen them at Auto Zone and other car parts places. They brag about helping fuel economy, but yes I have to agree you should have bought a CRX or a civic if you want MPG.

oh i'm not much for gimics. I'm pretty sure that if ignition modifications don't do it theres pretty much nothing else that will the problem is that ignition modifications will most of the time create better detonation but at the same time make you burn fuel faster cause they'll also make you go faster=\ I was hoping for the regular stuff with out getting into ignition boxes and such, if i could just hit 21-22 mpg city that would be awesome!

mine gets right around that, 20-23 city... and yeah, that tornado thing doesn't work worth crap.

I assume you are using the correct octane gas right? At LEAST 91 octane.
You might also want to head over to the 5th gen resource thread and do some of those maintenance/modifications. Cleaning your IACV should help, also can't hurt to adjust your valve lash. you should also clean your EGR valve if you get a chance... there's a bunch of good easy maintenance tips in the 5th gen resource guide.
