Hello M42 friends.
I have been on M42Club before.
I lost the name of my old account. I made a new one, and will keep this one.
R3vlimited is the other E30 fansite where I'am reading and writing.
Last summer I did rebuild my M42 engine.
I decided that on M42Club, I could explain and show how I did rebuild my engine.
First I start with background about the car.
I do own an 318is E30 built in april 1990.
The car was only registered on women since 1991, till I bought the car around four years ago.
In its first year 1990, it was not registered to an actual person.
Maybe it was a showcar in a BMW carshop for potential buyers, but this is just a guess of mine, because I could not explain it in another way.
When I was new to the E30 scene, all the engine swaps that people did impressed me, and I liked the idea of replacing the M42 by a newer and more powerful BMW engine.
As time passed, I started to love the M42 just the way it is.
I changed my mind, and I wanted to keep this engine and rebuild it.
I simply wanted a brand new M42, no matter if other people told me it is not worth the money.
Drive it until it explodes, get another engine, and so on...
The day I drove to work with my 318is was special.
I knew when I shut down the engine, next time it will fire up, it will be brand new. You guys sure understand that feeling.
I started in early morning on the first day, removing the tubes, let out the coolingwater and motoroil, removing the bonnet of the car.
Almost all the things that keep the engine connected with the car.

The top of the engine was clean because I had cleaned it longer ago, when I didnt know I was gonna rebuild anyway.

A workbuddy of mine helped me to pull the engine out of the car
(http://www.abload.de/img/bild06232gy5a.jpg) (http://www.abload.de/image.php?img=bild06232gy5a.jpg)
In the beginning we used a jack to support the gearbox, and prevent it from falling down as we removed the engine.
(http://www.abload.de/img/bild062288y67.jpg) (http://www.abload.de/image.php?img=bild062288y67.jpg)
After around one and a half hour, the engine was out of the car, and the fun part could begin.

Welcome back! I remember your earlier posts, especially the wheels!

Hi Dave, thanks for fixing it... :)
My car as it would rest for the next three weeks.
(http://www.abload.de/img/bild06204lybj.jpg) (http://www.abload.de/image.php?img=bild06204lybj.jpg)
The engine bay after the engine was just removed.
It was not possible yet to remove the exhaust manifold, so we left it in the car. The bolts were destroyed because of the rust, there were actually no bolts of it left, it was simply rusted together wit the exhaust pipe under the car.
We would fix that later.
(http://www.abload.de/img/bild0628icdu0.jpg) (http://www.abload.de/image.php?img=bild0628icdu0.jpg)
We put down the engine on a metaltable and started to take it apart.
Inside you could see the engine did not get much oil changes, and probably bad oil was driven over a long distance.
As I made my first oil swap on the car as I bought it long ago, the oil filter looked like a mess, you never saw such a dirty filter.
Watch the black background in the head.

I did not expect that timing gears would be in this condition, I thought the teeth would be sharp, so gears would have been replaced, but that was not the case, so I will use the gears again.

Now the head was off and we could take a first look at the cylinders, dont look to bad?

Now I went to preclean the parts with a pressurewasher in a washroom.
Just to remove the dirt and oil, so later we could inspect the clean parts, what could be used again, what had to be thrown away and replaced by new parts.

I prepared the engineblock. Used different kind of sand paper and a scraper before, to remove the old seals, and then make the surface clean and even.

(http://www.abload.de/img/bild0659ac86o.jpg) (http://www.abload.de/image.php?img=bild0659ac86o.jpg)
The same goes for the bridges, piston rods.
A before and after photo.
(http://www.abload.de/img/bild06620tm4g.jpg) (http://www.abload.de/image.php?img=bild06620tm4g.jpg)
Here we have the old clutch, it will be replaced by a new one.
(http://www.abload.de/img/bild06616586t.jpg) (http://www.abload.de/image.php?img=bild06616586t.jpg)
Later that day, I started to sandblast parts of the engine.
After parts are beeing sandblasted, I had the option to paint them, but I did not want to do that, as I wanted to keep the original look more or less.
Because sandblasted parts have no protection against dirt and grease, you have to polish them after you did blast them.
It is a hard job and takes alot of time, but the surface will become very smooth and will look clean for a much longer time.
Some parts before the blasting.

(http://www.abload.de/img/bild06659zjt5.jpg) (http://www.abload.de/image.php?img=bild06659zjt5.jpg)

(http://h9.abload.de/img/bild0699zealr.jpg)
(http://h9.abload.de/img/bild0700yyznu.jpg)
I also blasted, and painted pullies, dont know if this is the correct word. :D
(http://h12.abload.de/img/bild06704k79v.jpg)
The cylinderhead had to be taken apart. Remove the valves, the two sensors...
The valves were all fine, so I had to buy no new ones.
(http://h12.abload.de/img/bild0672kuueh.jpg)
(http://h12.abload.de/img/bild0671cm7rx.jpg)
(http://h12.abload.de/img/bild0673mx7d3.jpg)
(http://h12.abload.de/img/bild0674cu7qp.jpg)
Now I could blast, polish and, and seat in the valves.

The cylinderhead recived a first wash in a washbox with chemicalcleaner.
Later I did throw the head in a bath of another chemical cleaner over the weekend, so it will be become clean.
I could not blast the head because of the oilpaths in it.
(http://h12.abload.de/img/bild0675dh7ge.jpg)
The surface of the cylinderhead was then removed down around 5/10
Down until the rings.
(http://h11.abload.de/img/bild0682g8kdm.jpg)
(http://h11.abload.de/img/bild06861w8ri.jpg)
Because the cylinders in the engine block were worn out in top, the block needed to be bored and new honed, and for sure, I needed four new broader pistons aswell.
The new and old piston, old original one is from Mahle, the new one KS.
(http://h9.abload.de/img/bild0693vjyrm.jpg)
Some new parts arrived.
The new clutch, new starter, new generator.
I wanted it all new instead of waiting for it to fail sooner or later.
(http://h9.abload.de/img/bild0701kvzqn.jpg)
(http://h9.abload.de/img/bild0711xsyj0.jpg)
But back to the engine block, honing and boring.

Step to other parts of the engine.
Here we did polish the crankshaft.
(http://www.abload.de/img/bild07251su0z.jpg)
There were few little scratches in the camshaft mounts, so I polished these by hands.
After polishing, I did throw them into the chemical cleaning bath for twenty minutes.
(http://www.abload.de/img/bild0692hrulk.jpg)
(http://www.abload.de/img/bild0726ibuzq.jpg)
Made the flywheel a bit lighter, minus 2.5 kg, or 5.5 lbs.
I could feel the difference as the car was running again.
It revs faster, and the engine brake was not as heavy as before, really liked the result of this.

Came to the point where I could build the engine together again.
Painted the engine block simply black.

I did break in the engine for the first 3000 kilometers.
First oil change was done at 1000 kilometers, and it runs and sounds so much better compared to before.

Thanks for taking the time to post pictures and narratives. It helps me visualize the process as a whole...and makes me extremely envious!
-
Thanks.
-
Now that's some serious dedication to your auto. Car is gorgeous. Personally, I don't like the wheel color but I'm old so that might have something to do with it?
I am amazed that you polished all of those bits with hand wire brushes and a drill?! That's crazy. :)
Kudos to you.
How many hours do you estimate it took?
-Dean
-
Took me around eight hours.
-
On the interior I use E30 convertible seats.
You are able to sit a little lower in them.
It was alot of work to refreshen the leather, as the rest of the car.
The seats were worn out. It might not be perfect, but Iam happy with the result.
Same goes for the E30 M3 backseat.
Leather was going off the seat at points. A good friend of my dad is a tailor, he helped me out to fix the backseat.
I did not like they grey floor before, so I painted the floor black.
The headliner is black by stock.
Car had a Momosportswheel, which I replaced with an Mtech2 with new leather.
These were the majorthings. Other stuff is just minor.

So I bought BBS RS...

Is it possible that you have the most loved and doted on M42 powered E30 on the planet? Keep the uplifting updates coming!!
-
Mounted the RS on the car, with new tires.
Tires are 205/55 on front, 225/50 on rear.

O my.... So pretty
-
Those polished (chromed?) rims look so right on your car. What size are they (diameter X width?). Did you have to roll the fenders?
-
Wheels are BBS RS 001 for the front. 15x7 ET 25.
BBS RS 071 for the rear. 15x8 ET 18.
Not using spacers.
I think rear fenders are a bit rolled, since of the old 17'' wheels.
Wheels are fully high gloss compressed.
-
I changed some bearings of the rear axle.
And I also changed the O2 sensor in the exhaust pipe for a new one, was really hard to get the old one out, but I managed it without destroying the thread.
Powerflex bearings in:

You did a great job on the restoration! Is that the Mtech 2 wheel from R3V, is it brand new or did you have it wrapped?
Nothing beats a freshly rebuilt M42, It totally transforms the car.

Thanks!
The wheel is an old Mtech II, not a new one.
Its just got new leather and so on, like you said.
Bought it from a member in a german E30 board, so its not from R3v.

Mercy, that is such a lovely looking e30...
