The Proper Cleaning of the LSx engine bay..
i really do not have a lot to contribute, b/c a lot has been covered already. But here is my input
- Your motor must be COOL TO THE TOUCH
- Cover your PCM, Fuse Box, MAF/TB and Battery
- Rinse your motor with lower pressure water, be careful of the KNOCK SENSORS
- Apply what ever degresser you choose
- Let the degresser stand for about 15 mins
- Rinse your motor again with low pressure water, make sure you get all the degresser off. But again be careful of the KNOCK SENSORS
- Use 2 gallons of distilled water, this will ensure no water spots will be left behind
- Remove all necessary items you used to cover your PCM, Fuse Box, MAF/TB and Battery
- Dry your motor; whether it be by towel, leaf blower or comressed air
- Start car, let idle for about 20 mins to get nice and hot, also go for a cruise to get all the water out of tight spots.. Hint, go WOT
- Detail the car with what ever you choose
That should just about do it... Good Luck and keep that motor

Im a little cautious of doing this, I just bought a t/a with 99k miles doesn't look like the bay has ever seen a bit of degreaser. From what I've read on here so far main thing you need to do is cover up the pcm, maf, and battery. Should I be ok driving it to one of those wash booths and using the spot free rinse to wet it down and rinse it also?
It's been mentioned several times, but I don't think there is enough emphasis on this:
Water can (and probably will) get UNDER the intake manifold. The knock sensors are located there and sit in pockets. When water gets in those pockets it has NO PLACE to go except to evaporate. If it doesn't evaporate it will destroy the knock sensors.
If you have a bad knock sensor do a search for the GM TSB on a sort of "fix" for the water problem. If you need any more info on this, PM me and I'll be glad to share (I have pictures, too).
Other than that, cleaning the engine bay is a snap.

time for a good old fashioned resurrection. Call me a stupid n00b and flame me for these stupid questions but I'd rather ask them and get info than fubar my whole engine.
WHAT WHAT WHAAT is a knock sensor and where is it? annnd what is a PCM!? where do I find it and what do you recommend covering it with?

Knock sensor is on the driver side of the block.
A simple search will reveal these items, even a google search
Cleaning the engine area is a simple task.. Here is my view for it.
1. Wait for the car to cool( so I clean the rest of the car)
2. Take a bucket and I use the same car wash soap.
3. use the "mist" setting on the water hose.
4. use a rag and toothbrush(prefer the wife's haa) combination to get everything out.
5. let it sun dry (I also start the way with the hood open) I don't have a fancy compressor or leaf blower..
6. I prefer a light coat of WD-40, and wipe everything down(it also repels water) and once it dries it gives a "new" shine to plastic and rubber + it prevents rust..
You guys above got it covered tho..
Could we get some more before and after pictures?

i recommend Pine-Sol, one part pine sol mix with four to five parts water, in spray bottle is perfect. also works great on interior and leather, but be sure to condition afterward.
Weird, cleaning your engine bay resulted in a new lid, wire mod, and air/egr deletion lol.
Looks good, after doing motor mounts and seeing how nasty it was down there, I'll be doing this the next time it's warm out.

would anyone mind posting a pic highlighting the areas to be covered before washing? I know I'd feel a lot more comfortable if I saw another '00 camaro engine bay and which parts were covered before cleaning it. Especially with all this talk about being careful with the knock sensor! is the knock sensor coverable?
