Engine bay cleaning
Before the spring is in full effect I would like to clean my 986 motor/engine bay. I did a ok job when I bought the car a year ago. I have invested a small fortune according to my wife on the car as to be expected when buying a 16 year old Porsche. I would like to clean the old grease,oil, dirt, etc. from under the engine and topside. My plan is to mask off the cabin with plastic sheeting and use a engine specific cleaner. I have done this on my previous cars but this time I want a really good cleaning. I also will raise the rear of the car on ramps to clean under the motor. I will not use high pressure water but more of a fine mist from my hose. I usually use Meguiars/Griots products but does anyone have any tips before I buy any products or attempt the detail? I will use an engine detail spray to freshen up the plastics nothing that leaves a greasy residue.

My method:
Sprayer 1 - full-strength Simple Green Sprayer 2 - tap water Mist on, and then mist off (repeatedly) until clean. :) |
Be careful, you may inadvertently do much more harm than good.Water + low voltage electrical=problems.
It is cleanliness inside the engine that matters. We could give you n alternative to-do list if you want :-) ? |
I use Adam's In & Out Spray and a rag. I couldn't believe something as simple as this spray and a rag would do much until I tried it out. Now it's the only way I clean my engine bay. You can use it on every surface in your bay. You also avoid using any water in the engine bay that may cause problems.

I use spray 9 ( citrus cleaner ) and a paintbrush to loosen everything up then gently rinse with water. I go over it with 303 protectant.

If your UOA matches the outside - great !

So it looks like a 50/50 mix between rinsing with and without water. I have cleaned engines before and obviously your using a fine mist to rinse. Our engines are exposed to the elements for the most part so I can't see why a fine mist of water would harm anything. Its not like I will use a full jet of high pressure water on the alternator. What product do most use?

If you care to Google "washed engine problem" you may understand. On an M96 the OCD cleanliness issue is UOA not outside shine. |
most of the grime is at the undercarriage which is where I will concentrate on. As far as the top of the engine near the intake manifold I will probably concentrate around the out edges not directly of the top as I cleaned that area as much as I could by hand.

Good. That will help you track down oil leaks. Most are just a nuisance but some are good to catch early- like RMS or spark plug tubes or cam covers.
|
I use a small home steam cleaner and simple green. A stiff paint brush to loosen up anything that doesn't want to move and then blast it off with the steamer. The steamer gives control where a water spray does not. Makes the dirt disappear!

So the last time I cleaned the engine bay was may 2015
Changed my air filter today and here is how it lookedhttp://986forum.com/forums/uploads02...1493864955.jpg I simply wiped it down with a cloth and a bit of quick detailer http://986forum.com/forums/uploads02...1493865016.jpg |
Its an ugly engine and its buried in the car. Aside from cleaning up after a major oil leak, whats really the point? Best I did was wipe with a damp microfiber

A clean engine bay is easier to find leaks and other issues plus my OCD wants a "clean" engine bay.

I also wash my engines. Always use simple green or any of the citrus based cleaners, a nylon brush and a rag. Never pressure wash as I don't let them build up to the point of needing that and just don't want to get water into something that it doesn't need to get into.
One thing that I hate is when people use armor all or any of the other shiny treatments afterward. All they do is give a sticky surface for dust and grime to accumulate. They make the car look like it was on a used car lot IMHO. |

I used aerospace protectant, it seems to have repelled most of the dust for the last two years. |
