Title pretty much said all.

Thanks

 

...and a search will say even more. This has been discussed a lot. In a nutshell, cover all of the critical components (intake, fuseboxes, battery, etc) with plastic. Wait until it dries fully to start it.

Yep. Just spray any of the engine cleaners (GUNK, et al.) you can purchase at any auto parts store, let it sit for a few minutes, agitate heavily soiled areas, and hose it all off. I detail my engine bay every few months this way and have had no issues.

 

Thank all.

I will do the search feature next time.

 

Hose the whole thing off.

washed 25+ FD engine bays, more than once...

 

ok, i read that other thread and it didnt say anything about covering or not covering an aftermarket bov.. i know im an idiot but i want to make sure.. also, what about the a boost controller? i have a turboxs boost controller in there, can that get wet?

all the other stuff i understand..

 

If you are using a water pumps and don't powerwash the pulleys. I did it and destroyed a bearing.

 

i have sprayed everything on the engine on almost a weekly basis(or everytime I wash the car) on every car i have owned. I have never had any problem; I think that most people hype the danger. i don't mean that you should go spray all the electronic components without regard, but covering them with little plastic baggies or something like that is just a waste of time. the only thing i try to avoid on the FD is the turbos(if they are are hot) to avoid heat stress or the manifolds on a NA car.

 

That's my only concern too. I have power washed my engine and many others numerous times and everything is fine as long as you don't get stupid. No need to cover anthing.

 

I just let the motor/turbos cool a while then spray everything down...Didn't cover anything, just avoided the intakes and spraying directly on anything electrical. Done it several times and no probs here. But if you have a polished engine bay it can be a PITA to clean water spots after.

 

I spray mine down good with the hose almost every time I am working on it. Frequent washes keeps things clean so you dont have to use lots of chemicals or high pressure. I never cover anything up, just be careful and dont dont spray anything directly if it looks like water could get in and mess it up.

 

I use Simple Green automotive degreaser. Let it sit for a few minutes and scrub the really dirty and greasey areas. Works great. BTW - GUNK and other "engine degreases" do not recommend using their products on aluminum! Check out the directions on the can before using them.

 

Funny that you mention that Gunk shouldn't be used on aluminum when the US military has banned Simple Green as a cleaner since it corrodes aluminum...

 

Yes, check Simple Green's website FAQ, and scroll down to "Aluminum":

GUNK engine cleaning products OTOH, I've had zero issues with on aluminum parts.

 

Modern auto electric systems (in my experience esp. Japanese cars) are pretty well designed to keep the elements away. Most stock connectors have friggin' o-rings, and are designed for outdoor use. I wouldn't worry about any of it, unless your planning on submerging the car.

Though, I'd watch out for any non-factory wiring jobs you're unsure about, or damaged wires, for that matter.

 

Like everyone said above cover critical parts

If engine is realy dirty and greasy use
Castrol Superclean !
on a cold engine.
Do not get it on glass or on polished parts.

Semi dirty engine use S-100 found a Motorcycle Dealers

I Sware by both products!


After your done rinsing dry off with Compresed air
(from your air compresor) and a Towel.
