washing engine

Postby cacasplat3 » September 27th, 2006, 8:26 pm

ok, so i open meh bonnet to check meh fluids and i realised that the engine bay had a lot of dust, and sum water had splashed up from the under carrage and now that left some stains that cant exactly be wiped off.
i have washed the engine once before, and all the sensors and harnesses that could be seen were blown out with compressed air. now my problem is that i've been advised to not wash the engine bay.
i'm real picky about a nasty engine bay, so i take a paint brush and dust off the loose dust every once in a while, but for the things like the stains that dusting wont take off, i'm looking for a solution.

i dont want to wash the engine cuz many ppl say not to do it. do you all have any ideas on what to do? or any alternatives?
thanks ppl 8-)

Don't use high pressure water, and I don't mean like a pressure washer. I mean don't even use the spray attachment on your hose. Just use gentle running water. High pressure water can sometimes get into connectors, then when you turn on ignition, short out electronics.

Simple Green I have heard is pretty good as a degreaser. I use castrol super clean, but it strips paint, have to be careful with it.

Service stations have used Kerosene on my engine, then washed it out with a pressure hose then sprayed WD40 to displace the water. When I actually saw what they were doing (and how it ripped out the paint from my Valve Cover) I was horrified and I have not returned since.

But the kerosene and the WD40, are those bad practices?

i use keroscene and also the $10 cleaners and never spray water directly on any engine part
where i do spray water it is very low pressure, water can reach places where u can't begin to see

i don't cover anything but i wipe where is dirty and then rewipe clean, at least it may take longer but at least i have surprises when done

purple blaster not friendly to aluminium :!:
best option is Simple Green
If ur engine really nasty, there's Simple Green Crystal
Simple Green is also non toxic and environmentally friendly
and will not damage rummer seals and components cuz its water based

I covered all sensors with plastic bags, then sprayed Purple Blaster over the engine, followed by a thorough cleaning with a 2" paint brush. I washed the engine with water, using the paint brush, i.e. no hose or spray of any kind, with a pass over of Purple Blaster for the tougher spots. I then removed the plastic bags, and did the cleaning CAREFULLY around the sensors.

I then towel dried the head and various "shiny" parts, leaving the rest to air dry. After which I used the Turtle Wax tyre wax and sprayed over all the rubber components, using a small cloth to take up the excess. I then used the soaked cloth to give the head an extra shine.

This brought a very dirty engine bay to showroom condition (the Purple blaster even cut grime from the body in the engine bay area and on the firewall where the chassis number is), and all that it needs to maintain that look is a quick wipedown every weekend and a couple sprays of the liquid wax.

I used to use WD40 to get the engine bay shining, but that attracted a lot of dust and when the engine got hot, used to fume a lot when vaporizing. I didn't like the idea of driving down the road with my engine bay smoking.. :lol: :lol:

So far the tyre wax is working wonders, and it doesn't burn off easily. (AND it's non-flammable!!!!!!!)

^^ The key point here is that no water spray of any kind was used in my engine, and for added protection the sensors were covered.

I learnt a major lesson with my first engine wash at a well-known car wash place, with a pressure washer. A day later, the ECU started throwing CELs, which is a cause for panic with ANY engine, especially an Evo. Checked the code with Robert Chan's diagnostic tool, and it was the TPS and a couple of other sensor faults. After they were cleared, only the TPS fault re-occurred. A thorough spraying with CRC fixed that issue.

Since then (and based on his advice), I only apply water to my engine with a small paintbrush.

first off, thanks for all the info.
secondly, there is no greasy spots on the engine, its just 'dirty water' stains, and lots of dust and very very small stones.(these collect in the space between the 2 banks os cylinders)
i'm not in a position to cover all the sensors in my engine bay, by doing that i'm covering almost everything. :?
the engine has coil packs, i know these are not supposed to get wet, by washing the engine (even with just runing water) the packs will get wet :|

my only guess is to remove the plastic engine cover and whatever stuff that blocks up space, and just blow out the engine with compressed air, as for the stains, it wont be easy, but i think i'll wipe it off with a wet cloth or sumthing.

Man I thought it was diesel? In the service station I go too, they use diesel... and breeze...

take my word for it, never let ppl spay your vehicle with diesel. it softens up the rubbers on your vehicle, and eventually they burst. cuz of doing this just once, i had to change 4 engine mounts, stabliser bar rubbers, stabliser likages, a cradel, two booth rubbers, plus sum other rubbers i cant remember. in total it costs over $7000 to replace those things. so dont do this. :wink:

I don't think spraying your engine with breeze/diesel/water will cause $7000 in damage after ONE engine wash pal... :roll:

^^^^^^ wasent the engine. it was the entire under carrage. man u should have see what that diesel did. almost every suspension rubber i have had to be changed. i still have a couple rubbers to change, only thing is i cant get them without buying the entire back banjo. and that is really expensive.


man if u doubting me, thats yur decision, but i can safley tell you that the diesel was the cause.


....any difference in washin a diesel engine vs a gas engine....do you have to be as careful....

i wouldnt say u have to be just as careful,but be careful, still. because gas engines generally have a lot more sensors. if u can cover up whatever sensors u have, then IMO it shouldnt be a problem.

I washed mine this weekend using my own pressure washer. didn't set it to full pressure. First of all i removed the stock airbox by de rad and then covered the opening to the air filter. also tied in the air intake temp sensor harness in there to. then took off the engine cover(de nissan cover eh) den i washed it out, making careful note not to linger on any spot. the prob is not gettin to much water in the middle of the V where the intake bolts to the engine. Then i used a wet and dry vacuum that has a blower to the top to blow out all the water. (note, it's not pressurized but it does the job). When i started the engine it started in a 1 an i jus let it idle to dry out any excess. no probs since. will check to see if water got in the spark plug guides but as the engine slant i doubt, any water got in.
