lots of people just go to the carwash and use the pre-soak and then rise the whole engine, i always was worried about it, and several people have said as long as you start your car after its fine. Jassics on here sprayed his 2nd gens engine and he had a bunch of problems after (IIRC low idle and stalling). i was about to spray my 3rd gens engine bay but that made me not want to

Simple Green or Purple Power, brush heavy grim areas with a soft brush.
Rinse well, blow dry with a leaf blower and then use your favorite dressing to really make it pop.

Dawn dish soap + hot water in a spray bottle with the nozzle turned to the jet setting. Spray the engine bay down, let it set for thirty seconds, and then blast the engine with some high-pressure water. Then hit it with a leaf blower.

Worked decent for me. Didn't have any issues afterward, either. Just makes sure if you have a CAI or SRI that you remove the filter and cover the intake tubing with something.

i just removed my AE engine cover use purple power full strength let the engine warm up w/ the degreaser doing its work, softening teh grime, then shoot it down with the garden hose. sometimes i hit it w/ armor all to give it a shine, but lately i havent.

bring some saran wrap or plastic bags to cover your CAI/SRI filter, MAF, alternator and any exposed electrical areas and you should be fine. do the rest as everyone else says... degreaser/APC and low-pressure hose off. then some protectant.

FYI i've never covered my components (although i've worried about my HIDs) and have never had any issues.

simple green for life... Spray (trying to keep away from hoses if you can) a solution 2X what ever the bottle says to dilute it. Let it sit for 5-10 and then rinse off. You will smell simple green for a while if you dont rinse the driveway down.

engines can obviously handle water without being submerged, but it's just to be cautious. if the OP is worried about damaging his engine, just a bit extra protection might help. i've only covered my filter and alternator before, and been perfectly fine.

ive thought with the dish soap thing, it fawks up your paint? i looked it up and people are saying its micro-gritty and can scratch, and theres salt in it

phatboislim

iTrader: (27)

another FYI...rinse your fenders before you spray the degreaser..it could mess up your paint

Mr. Brett

iTrader: (7)

No, it's not micro-gritty. That's Gojo. Dish soap's grease-cutting ability removes the wax from paint, which is why it's so bad for your car. In other words, if you'd like to start from scratch with a fresh coat of wax on the paint, wash your car with Dawn. Just make sure you wax directly afterward.

In the engine bay, it's not going to make that much of a difference. Especially if you just spray it on, let it sit, and then hose it off.

yeah i heard on Yahoo answers and another site that its gritty and stuff, more sh1tty answers from Yahoo lol

sweet gonna try this

Oldgeezer

Simple green! That stuff can be diluted like 10:1, so one bottle goes a looong way.

Just don't spray directly onto electrical components and you'll be fine. Even if you do, the car will misfire a little and stutter. Once the water dies up from the heat of the engine bay, everything will be normal again.

i use purple power

Mr. Brett

iTrader: (7)

I just throw clods of dirt at my engine bay and then spray everything down with a hose.

Nothing says hardcore racer like the filthy, muddy, look of an engine that appears to have been in rally races.

Oh yeah, pouring sand into your intake while the car is running is a good way to clean out the upper manifold, too.

A citrus degreaser is good for your purpose as it wont dry and crack the hoses and other rubber in the engine bay. Just spray, brush and rinse. I did this on my dd last weekend and ended up tearing the hoodliner to shreds with my pressure washer. So pressure washer may not be a good idea.

chrome91

iTrader: (1)

lmao this thread still reminds me about the idiot who cleaned out his Mustangs engine with water and was complaining that it wouldnt start

ivorton23

i remember taking my datsun for an engine wash and the guy didnt cover my distributor and it was bucking and stalling all the way home. when the water dried it was back to normal.

Did this over the weekend. Wow engine bay looks great, just gotta finish it and paint a few items lol

I have used this stuff in the past. Works great.

I use DP Engine Degreaser, followed with a light spray of Sonus trim and Motorkote, and the engine looks great.

Dave Holmes

The cheapest can of engine degreaser from AutoZone or Advance Auto. ~$3.00 for a can, and extremely effective at removing grease and oils. Plus it is safe on all underhood materials.
Problem wth Simple Green (and IIRC, Purple Power) is it's alkaline. This has the very real potential of eating into aluminum parts (basically, most of our engine covers, block, etc...). This makes them oxidize extremely fast, resulting in a white, chalky appearance on the surface. It's aluminum's equivalent to rust. If you must use it (and some people do with no problems), I'd take simple recautions like diluting it and not leaving it on the surface long. I've learned first hand the hazards of using it on aluminum without those precautions. For that reason, I don't use it anymore, even though I really like the smell of Simple Green.
As for damage from water, common sense should be used. I don't spray anything directly on my alternator and don't use pressure on/around electrical connections. A leaf blower or a highway drive dries everything out nicely.

thanks for all the replies Dave Holmes cleared up was i was wondering about seen alot of the white corrosion on engines parts on peoples cars wanted to steer clear of that

I used rim cleaner on my engine bay, so far no problems!!!!

Haha old repost but still not better than the Audi Sand Port n Polish.

what works great for me is to use foam engine brite degreaser. Put aluminum foil and seran wrap over any wiring that water could damage and just spray a bit of the degreaser around, then blast it with water from a hose, go in with a brush on any metal details like the intake manifold.

Gotta look for that one

BENMAX03

I just used the cheapo autozone engine degreaser today and it worked great! Just wanted to throw that in.

Acadian

cover your alternator with a garbage bag. then rinse your motor with the garden hose realy good. After spay the engine bay with spray nine all over let it work for a couple minutes and then rinse it all off and voila. dont forget the garbage bag on your alternator.

grease is good, it keeps the engine from rusting.....

Acadian

The VQ35DE engine is an aluminum head so it’s very hard to rust but all around it it’s good to have the clear or yellowish colored rust proof coating but the downfall is that dust and **** sticks to it.

just got mine cleaned he used a degreaser and it looks brand new

Im afraid to do this now because of my projectors. I have done it twice before, but I didnt have the retro then

illmortal

Agreed did this over the weekend with AutoZone's engine degreaser + pressure washer, my engine bay looks beautiful

I had to clean it up after my radiator blew + oil leak out of valve covers.. No way was I doing that by hand either.
