Me on my first trackday.

Car had some refreshments.

All suspension rubbers are renewed (I mean, all of them). Bilstein B8 with H&R -35 springs, Z3 1.9 SSK (which I like very much!) and Mark D chip. I renewed every single part of the distribution and most of the hoses under the intake. The car's idle is great now!

Damn, I love it!

After some tracktime, one of my brakes came lose, mangled the alloy, bend my new control arm, so that was it.

If there's interest, i can put the pics of all the work done on the car here.

Ok, let's write a bit about the history of the car.
2.5 years ago, I bought this car for a small price. It was my first car and I didn't know a thing about mechanics.
The owner gave me a confident feeling. The engine didn't run, but he said it was just a small fault and easy fixable. Body seemed ok, interior was kinda bad.

Later turned out that the chain slipped, intake valves bent, so I bought a second car for almost the same price and used it's engine, which had not so much miles on it. There was some rust on the car, which I got fixed and I used some of the seats of my 2nd car and renewed the engine.

Results: kinda good engine, interior looking quite well, but with suspension parts, still original from factory, worn rubbers, ...

Being a student, I drove the car for about a year (It took me about one year to put it on the road.) Then I went to the Santa Pod (UK) BMW meeting, broke some tooths of my diff and noticed that my front subframe was torn at the engine mounts. Due to a mistake of us when swapping the engines.

This was the point where I decided to renew all of the suspension rubber (every single one!), a new suspension had to be installed, the subframe needed to be fixed and since I had a Mark D chip waiting to be installed, I wanted to do the timing chain job too, because it was noisy between 3 and 4K rpm, only when at operating temperature.

First of all, I started shopping. At the same time, I had some engine parts cleaned. Luckily, I have two spare M42's, so I could still use the car when some parts were being cleaned.

Some things I bought:

Good tools make the work easier

5 Weeks before the deadline, we started working on the car. We decided to remove the rear and front subframe and the engine, leaving almost just the shell and its interior.

Prepartion: street mechanics. Removing the bolts from the rear drive axles



After one weekend, the car looked like this



Two subframes removed.

On a lazy wednesday evening and after 3 hours of work, this happened:



And the car was em-pty



The checklist: (in dutch)

I decided to remove the front also. The car has had a collision on it's right handside, and the front bumper sticks about two inches out of the grill. I wanted to take a look at it and try to fix it (which I couldn't)



Some things removed from the car



Location of the rear subframe



No oil dripping allowed!

After removing the rust, repaint most of the parts





Old new subframe, from a '86 316 :D



suddenly things started moving. We only had 3 days left until the deadline, which was a trackday I was attending. The car needed to be ready.

Due to delivery problems, I still had no rubbers for the rear axle. Luckily I have a friend who has these things in his sleeping room, so I could borrow one for a few days (or weeks :D). That's why there are no pictures of a new and freshly painted rear axle. His rear axle also had new rubbers, so that was sorted out!

Rear axle with new springs and shocks installed! Looks shiny, doesn't it?



And the front suspension struts


New top mounts
new wheel hub and things
freshly painted front struts:D

On saturday, I did the timing chain job. It took me far more time than expected, but I did it very slow, making sure not making any mistaks

Saturday evening, the engine was almost ready for installment. We still had the sunday to work on the car, Monday evening we had to be at our hotel in France.

Sunday:
I also renewed most of the vacum hoses under the intake. I left most of the water hoses apart, I renewed only the hard plastic one and the two heat change thingies. I have no leaks, luckily.



Engine compartment cleaned and front subframe installed. I also renewed the brake lines to the back of the car, a new clutch slave pump, ...

Moved the engine back in, renewed the oil seals of the gearbox, installed 1.9 Z3 short shifter (I just realize that I have no pics of those things. Sorry, we didn't had that much time left :D)

Putted the body parts back on, installed the exhaust, used new engine mounts, gearbox monts, and a lot of other parts that I'm forgetting at the moment.

After + 14 hours of non stop working, ordered a pizza at 12 o'clock in the evening :D, the car was ready for it's first test drive. 6 o'clock in the morning, easter monday.

Putted the contact in 1, the dash came alive and the water temp popped into the red. Damn. We came fast to the conclusion that I switched the connectors from the oil pump and the water temp sensor in the head.
For the people who knows the M42, they know that the water temp sensor is nicely hidden away under the intake. Not wanting to remove the hole intake mess, and with the help of a screwdriver, I managed in less than 20 minutes to remove the connector, switched it on the oil pump and pushed it back on the water temp sensor. Try it yourself without removing the intake :D

Second time, everything seemed ok, started, wait a few second until there's some fuel in the lines, engine puffed, one more, vroam. M42 was back alive. No rattles, already popped out tensioner did it's work good!

Brakes needed bleeding another time and we did it's first kilometers. At 4 am we had made plans to go to Paris, to break in the car, the suspension and the timing parts. Due to the sensor, the bleeding and the fuel problem we had to set those plans aside.



Mondaymorning, the first trip ended a bit with a downer. Easter Monday, 7 o'clock in the morning and no fuel. After 14 hours of non stop working on the car, pushing is the last thing you want to do.



But after all, the car drove, and like hell! I was impressed. What a great thing to drive.


Pitty that the trackday didn't end so well, but I'm going to write about that another time. Long story short, I need a new right front strut, possible a new shock and some other things.

I'm really sorry about the picture size. Most boards I visit have an auto picture resizer and I'm really wanting to do something else at the moment than resizen and reuploading pictures :p
