This is going to sound like a REALLY, REALLY STUPID question. Can someone tell me how to go about steam cleaning the engine of an 83 Supra. I told you it was going to sound really, really stupid but I am no mechanic; I build, fix, troubleshoot computer systems and networks.

Its actually quit simple Ed.... First you take your backup domain controller down off the network, then you need to add a new scope to your DHCP, re-subnet your network and disable DNS for any IP address that is class C... :wink:

Seriously... Its not too hard. Remove the AFM and cover the open hole in the intake pipe that is left, remove the coil and ignitor, and cover the Fuse block (I used Aluminum Foil.. works well... stays on relatively well, won't melt, and if ya wrap it right, keeps all the water and steam out of there). Then the only other suggestion I can make, is to try not to spray directly on any of the sensors (A co$tly mistake I learned on the blue car... In fact... when I do it to the black car, I plan on removing them entirely..)

Bob,

Where are you located? The first part of your reply was good one.

well i dunno about steam cleaning but take the vacuume line off at the top of the intake manifold and stick it in a glass of water with the engine hot and at between 2500 and 3k. i'd recommend no cat when doing this cuz excess carbon buildup can really plug a cat up good. i did this with a mower of mine and didn't think to move it away from the house...i almost never got all the black off out white house lol so i just repainted there. my mom said to clean the whole house cuz that one spot looked to nice...shhhh!

Other things that you don't want to get too wet.

Distributor

TPS

All of your CE diagnostic plugs (too much water got inside the plug on mine & the CE light was doing a steady blink. Thought something was wrong, discovered it was the water that got inside).

If you are using a open intake element, cover that up as well.

Once you get excited blowing off the grime you're going to wanna try but..
DO NOT spray the hood insulator piece.
If you dont believe me, try it. :roll:

it depends how exactly your doing it.

i go to a carwash i used to work at, and use their "tire and engine cleaner" because i know it actually has solvents in it... does a half assed job, but youve got to repeat the cleaning regularily if theres built up dirt.

it comes out at a lower pressure, and a fairly solid stream, so you can aim it pretty well.
i just avoid all the electrical stuff i can, if i happen to spray something, i either wipe it off, or spray it down with wd-40 (let the car COOL before starting it!)

hmm, ive also been known to put it on soap, and high pressure hose everything, from crawling under the car all the way up to the insulation.
it does get it fairly clean, quickly, but youll miss spots and the electronics are in danger, so do that at your own risk.

Wet the engine compartment with a low pressure hose.
Using full strength Simple Green, throughly spray the engine and surrounding areas.
Let sit for 5-10 minutes but do not let it dry, respray as needed to keep wet.
Scrub stubborn build up with a small brush if needed.
Rinse with low pressure hose.

This will even work with the hood insulator mat.

Go for a drive to dry the the engine and surrounding areas.

Engine bay will look good as new.

i'd be careful with using too much water tho cuz between the cams water likes to build up.

Had this happen. Drove home with it there. By the time I got home the water in the valley was boiling. By the time the engine cooled down the water had boiled away. It wasnt above the plugs though. Didnt seem to hurt anything.

 

[Tanya]

my best suggestions is to get some engine degreaser, and cling wrap, tightly wrap up all the sensors, using rubber bands if necessary for the check connectors, spray the engine down w/ degreaser, let it sit well for about 10 minutes, spray again, let it sit for another few minutes then hose the engine down, should look real good.
Words of caution, try to keep away from the spark plugs or it'll be a PITA to start until the plugs dry off and if you get water between the plug valleys, you can use like a turkey baster to suck it up along w/ any dirt ( just don't use the baster for cooking anymore )

i always used the purple stuff from discount to clean my 5m. worked really well. havent cleaned the 7mgte yet. too many friggin wires and sensors. lol

best way to clean the motor....

remove motor, and clean with toothbrush...lol....

personally i find the carwash vacuums work real good to get that crap outa there

External cleaning rite??? spray solvent (degreaser) let sit spray iff with hot water.. carefull of all conector just spray soap(solvent) off. if you can get a hold of compressed air you can just blow everything off.. just be carefull....Good Luck

whaaa?

 

[Felixatvtc]

Ok stupid/silly question. What sensors should i be worried about. Can anyone photoshop up an engine bay picture with appropriate warning areas :?:
I know i'd find it helpful

 

[MAD_83supra]

Heres is how i do mine ( my car leaked up to a quart of oil per tank gas till I resealed the engine and tranny last week) So it was a real mess.

You need an air compressor to attach a siphon feed spayer. Home depot carries them for about $20. (No compressor? Garden pump up sprayer works too)
Then go the Walmart and get a gallon of mineral spirits for $2. Spray any greasy areas liberally(i dont spray the spark plug galley or the fuse box area). Use a parts brush on the very bad areas. Hose off with garden hose but not into the spark plug galley. The spray simple green all over.. wait.. hose that off.. Fresh as a daisy.

whaaa?

it gets rid of the carbon deposits in the combustion chambers(a side benifit to water injection on turbo vehicles), although id recomend a smaller vacume hose for this myself, like the one going to the power steering pump from the intake crossover pipe.
