Here's a D.I.Y. thread of before and after of my engine detail.

This took about 4 days total, can be less depending on how dirty your engine bay is.
I used WD-40 and a paintbrush and 4 microfiber towels.
Works amazing on 20 year old buildup of dirt and rustproofing. No joke. =)
Car had been sitting for 10+ years.. Buildup of rustproofing and dust on it takes its toll.


Step by Step:

1. Go to the automotive store, buy 2 cans of WD-40 , 4 microfiber towels, paintbrush.
2. Open Hood.
3. Remove battery, air filter box and arm, fuse box cover, wiper motor, map sensors assembly, coolant overflow tank, move away side wires and tubes on shock towers.
4. Start attacking the dirtiest parts with WD-40.
5. Spray and brush/agitate the grime/dirt
6. Wipe off dirt with towel.
7. Once all the bay is clean, you can buff and polish the paint around the bay and dress the rubber hoses with rubber and vynil dressing.

Keep doing this until all dirt is removed. It takes a while, but well worth it.
WD-40 wont remove the paint.

AFTER"

 

good write up. my engine sure needs a cleaning

thanks

 

looks really nice after man!

 

That's inspirational.
Nice work, Rob.

 

wow that engine bay looks mint. Ive detailed my 92 and it def isnt in that good condition

 

this looks like 2 different cars!!! lol how much for you to do mine????

 

Check PM

 

You used wd40 as a cleaner?.. I've seen P21s being used but never wd40

 

wd40 breaks down the gunk easily

 

It depends how thick and dried up the rustproofing is.
In this case, the buildup was 20 years ! WD40 breaks down the gunk with a little agitation.
In most cases, simple green or any other All purpose cleaner is sufficient.

 

wow i wasn't expecting it too look as mint as that, good d.i.y

 

WOW .. incredible.. will defo try this out and post before and after pics.. thanks

 

by the way.. what kind of paintbrush.. does anything need to be rinsed with water after or anything?

 

On occasion, you can clean the bruch.. have a bucket of water handy, but not necessary.
I usually just used the rags to clean the brush.

 

works great im going to do it again,bay is getting a lil dirty again.this time im going to do the hood first lol.

 

Guys, it's not necessary to use WD40 unless your engine bay was as bad as mine.
Mine had 20 year old hardened rustproofing on it.
In most cases, using all an purpose cleaner or degreaser, with powerwashing is sufficient.

 

wow..that looks immaculate!
did you paint your valve cover?

 

Yes powdercoated. Lasts longer than the shitty Honda valve cover paint!
Plus mine was chipping at the base.

 

what type of paint did you use? what brand?

 

The valve cover was powdercoated, not spray painted.
