When I posted pics of my engine bay a few people asked me to make a guide ( my bay is no way the nicest on the zone...but I have a lot of time and want to contribute so here goes ) This thread is ongoing, Il do it as I go so bare with me. All work will be done without removing the rocker ETC so it does not need mechanical skill.

Il show how to
clean bay
polish metal risen parts
paint rocker/inlet
paint/polish other metal parts like throttle
hide or cover bottles + cables

A lot of guys dont care about their bays ( barx I remember said he doesnt care, aslong as it works which is fair enough ) I totally can understand this viewpoint but i prefer it looking nice and tidy.
I got it to this point a few weeks ago but it was a rough job and now im doing it all properly

Image

As you can see here...there pitting on the metal and its annoying me greatly
Image

I decided to redo it as I want my car to look as German as possible plus there was ALOT of pitting on the polished parts.

Iv decided on this as a design
Image

Before you start, heres a little inspiration. Iv been called dubscum but thats pretty accurate, it was vw that got me into the euro scene and made me remember e30s...it also gave me a love for clean bays

[youtube][/youtube]

First off you will need

SANDPAPER

120/ rough grit ( this is if you have extreme pitting like I did )
600 grit ( this is to get the parts shiny-ish )
1200 grit - to get rid of the scoring left by the 600
1200 waterproof or emery cloth - this is to get to the final point before polish

METAL FILE - this is to bring out the metal on the emblem/bars on the intake ( often these corrode and fade ) the best way to right this is to file them a little

AUTOGLYM - or other metal polish


PAINT

This part is very important, decide what you want very carefully ( I have been informed that you do not need engine paint for the rocker, normal spray paint shall do just fine....you will need heatproof for the manifold )

MASKING
masking tape/tape
paper,newspaper or bin bags

Step one

The best way to start is by getting the shiny parts shiny...this is because innevitably you will score or mark the inlet/rocker whilst doing so and if youve already painting it this is a pain in the gentleman vegetables.
Start off with the emblem and bars on the inlet manifold...take a metal file and very carefully file the raised parts

CAUTION!
This is soft metal and wears down VERY quickly, if you file too much it will disapear completely, keep the file very horizontal so you dont angle it all. Use 1 or 2 strokes on each part...this is plenty to get it shiny.

STEP 2

Once youve done this you can start on the rocker cover. If you dont have pitting ( chip like marks or deepened fades ) ignore this, if not read on mofos. Take your heavy grit paper and begin to sand the letters...start on the letters for the same reason and youve started on the polished parts, if you shine up the bars you will score them when doing the letters. Yes I learned this the hard way this afternoon. Keep all the sanding in the one direction. Vertical for the letters, horizonal for the bars. This may take a while but trust me its worth it.

TIP
This job is utterly soul destroying but if you dont do it you will regret it...I did a half assed job and now im having to redo it all, dont make my mistake aswell. If theres pits get them out, when the rest is mirror shiny they will show up even more than usual.

Almost done....
Image

STEP 3
Once youve got all the pit marks out and the fades your ready to get the scoring out left by that nasty 120 grit. Get the 600 and follow the vertical on the letters ( doing the letters first ) and then the bars horizontally until they look smoother and there are no scores. You want to be keeping the area clean as possible, dusting and sorta cleaning so you can see whats done properly. Then take the 1200 and do the same. Once its all smooth your ready to autoglym ( wait )

No more pits!!
Image

Image

Step 4

Take your tape and very carefully mask off the raised areas youve just slaved over for between one and ten hours ( dont mess this up or youl feel like a dafty.
You then want to remove the harness bar ( 6 bangers ) the black bar that sits above the plugs, its just held on with 2 or 3 little nuts. You then want to cover the windscreen in bin bags or newspaper. carefully mask off the throttle assembly and cable ( DO NOT GET PAINT ON THE CABLE ) as it may get sticky or jam on. If you do, sand it off or itl bite you in the ass later. Take great care masking off the hoses and radiator, just use your brain, if your gunna be painting near it, cover it up.

Make sure to leave no gaps, over spray on the screen = BIG PROBLEM
Image


Make sure to tape round the tricky parts like the throttle carefully, you dont want sticky paint jamming the throttle waiting there for you on a sunny day when you decided to give it some tits.

Image

Image

( will be showing how to mark the letters as soon as the feckin rain stops )

Step 5

Take the 600 grit and roughly sand the rocker and intake main parts. Blow off the dust and wipe the area clean. ( pictures of this and masking to come )

Step 6

Carefull spraying evenly around 6-8 inches away from the parts, apply the colour of your choice to the area. You want to apply two or three coats leaving 10 minutes between.

Step 7

Once dried take off all the masking on the bars and letters and look at your work so far,. Take your metal polish/autoglym and a cloth, applying a small amount to the cloth, in circles begin to polish the metal on the rocker ( this will not work on the soft intake ) Be careful not to get too much on your new paintwork. Once its looking nice and shiny, take a clean cloth and wipe off the excess metal and polish.

Step 8

Take clear coat ( If you want a matte finish remember to get matte clear ) and apply to the whole of what youve just painted including the metal ( this will stop it coroding again )
Remove all of the other masking and go get yourself a fucking beer, youve earned it!


There will be more parts to come, including how to hide reservoirs and paint other pieces like the manifold. Silicone hoses and the like - I will also be getting more photos as i finish my bay over the next few days.

Hope this helps a few of you

Good guide Verde, I degreased and painted the rocker cover when it was off, then carefully sanded back the raised letters with a sanding block after painted. Quick and easy with great results.!

There is a benefit to having a nice clean grease free engine bay, is when you put the blowers on you don't get the smell of a hot oily engine inside the car...!

Thats definately the best way. If the covers are off do it then. Its so much easier, but if its on and u cant afford or get a new gasket just leave it on.

Definately cuts the oily smell. Plus its easier to see if you have a leak " why is their oil allover my paint " as opposed to, theres oil allover the place anyway its nothing-2 days later engine seizes

It may take a while but it could be a nice addition especially if I get it how I want. I want to get either hidden bottles or stainless steel reservoirs. Maybe individual brass throlle bodies one day, silicon hoses. Get it a proper full on guide of how to be wagenwerks ready

u cant go using a grinding disk on an e30 if u leave the rocker in look at all the fuckin wires. Clip one of them and its game over.

U did a good job on that though

a knot wheel will probably gouge the alu of the e30 rocker cover and will go through an exposed wire like a hot knife through butter.

Painting has commenced. Since i got ill i can no longer paint which saddens me, so im teaching my friend how to spray, so it will take longer than usual and the finish wont be AS good...but its looking nice so far.

I'll be doing something like this at some point for mine...although I have a spare engine and so can do it all off the car even when the car is running. :D

I also need to give the actual bay a good scrub whilst there is no engine in there and try to clean the block up as much as possible too.

Yeah man thats the ideal situation :) much easier when its out and on a table or something

I was speaking to my old man ( good with bikes ) about fitting individual throttle bodies but decided it would be an absolute bastard unless i could find something that would fit right on. Found e46 m3 ones on ebay but doubt theyd even nearly fit.

If anything get some proper masking tape that parcel tape is nasty stuff, only a couple of quid and much cleaner to use.

As an engine detail homo im interested,

This was my first M30.

Thats fucking gorgeous man! I didnt have time to nip out. And I had to give up.spraying cos it permanantly thickens my visual snow so.all my.paint supplies like the masking tape went. Its nasty but it proves noone has an excuse not to do it...u can do it with anything u have, sellotape bin bags, sandpaper
