Slowly, the bottom end progresses

With the crank in the block and the pistons and rods assembled, next was putting them into the cylinders.

First, rods needed to be separated. The bolts were torqued down pretty good and I needed a little help loosening them. An impact wrench does the trick.

Then, on goes the ring compressor.

And placed in the block (with rod bearing installed and assembly lube applied. Also, make sure the crank journal for that cylinder is at the bottom of its stroke, so the con rod doesn’t ding it (don’t ask me how I learned that lesson!).

One at a time.

Eventually, all six are in.

Torque the rod bolts.

And if you’re lucky, it still turns.

Meanwhile, the reassembly of the body has stalled, waiting for a new headliner. The head, too, is MIA, still at the machine shop waiting for “the end of the week.”

Up next: oil pump, flywheel and the head getting back for the machine shop and then mating it to the block.

Tomorrow is today – or, more correctly, tomorrow was about a week ago

Tomorrow is today – or, more correctly, tomorrow was about a week ago

Avid readers will remember that the body work was chugging along, accomplishments each week to keep the momentum going, but the machinist seemingly was making no progress. For months he kept promising to be done “by the end of the week.” And then, about a month ago, “by the end of the week” turned into promises to finish “tomorrow.” The “tomorrow” promise went on for weeks.

Well, tomorrow finally came. About a week ago. For the lower end. Which was picked up and carted off to my garage, leaving the head behind to be completed, yes you guessed it, “by the end of the week.”

Since I knew assembling the lower end would take me a couple of weeks, I have not called the machinist about the head. Instead, I started chugging along.

Before assembly could begin, I needed to (wanted to?) paint the block. While I asked the machinist to do that about a month ago, I saw it was unpainted when I went to pick it up. My friend helping me advised, correctly, not to say anything. Rather, we took it home, I taped up the openings and primed and painted it, black.

Then I tried to figure out which way the end caps went (internet research helped as it wasn’t obvious from trying to fit them).

With the order and orientation of the end caps clarified, it was time to install the rod bearings in the block.

And the end caps.

Then it was time for the turbo diesel crank.

Gently place the crank in the block.

And install the end caps with bearings.

And, miracles, it turns freely (as if I know what I’m doing)!

Next, gap the rings.

And install them on the pistons.

Then attach the rods to the pistons. The hardest part being, without the right tool, installing the wrist-pin retaining clips.

A New Year

A New Year

According to Stu, it’s best for the project to keep momentum. So, while there was certainly time to finish the body and paint work since my last update in early December, he chose to do a little each week (holidays excluded), slow but steady. This approach was perfect, as the motor parts were languishing in the machine shop, that turning into it’s own little comedy.

While it might have been a little overly dramatic to call the comedy with the motor a tragedy, I tried to appreciate the humor in the situation. For background, when I dropped off the block and attendant parts in November at the shop, the machinist said he’d be finished in about two or three weeks, as he reeled off a list of projects that sound like they wouldn’t be finished in twice that time. I was in no real hurry, as the justdashes.com was not going to finish my dash until mid-January at the earliest. That meant the body would not be ready for many months. So why rush on the motor?

Who knew that meant that more than three months later I still wouldn’t have the motor back from the machinist?

Now, to his credit, after 10 weeks of saying his work would be finished by the end of the week, the most recent time I called he said it would be done “tomorrow.” That was three days ago. But, progress!

Real progress: the slow but steady body work.

As previously reported, the hood and trunk were painted in November and in early December Stu finished rust repairs and priming the body. That continued a few days a week.

And then finally the shell, including the engine compartment, got painted.

Next? The “new” dash and the glass will be installed and the body re-assembled. And with any luck, “tomorrow” may eventually come and the motor parts will be ready for me to begin assembling the motor.

Frustration and Progress

Frustration and Progress

Almost a month ago, progress was slow but hopeful.

The car had been taken to Sacramento and the shell stripped down. Motor parts were ordered, acquired, and taken to the machine shop. I wrote about both tracks progressing, but slowly.

Since then one track is completely stalled, the other chugging along.

Stalled is any progress by the machine shop. He’s busy building another motor – this a 4 cylinder air-cooled Porsche variety. What’s taking so long isn’t clear, other than, well, it’s taking a long time. Frustrating.

Body restoration, however, is humming a long. Disassembly and repair continued. The torn spare tire well was touched-up. The rusty, torn piece was cut out.

And some sheet metal welded in and made to look pretty.

And blended in.

Rust was found hiding under the rubber trunk gasket.

And welded up.

The engine compartment continued to be cleaned up.

And the battery tray – the original culprit starting me down this slippery slope – was welded back into place.

The front fender gets cleaned up, including plugging the holes for the USA sidemarker lights.

Waves a long the rear fenders and roof are smoothed out.

And the air dam gets cleaned up as well.

Next up: finish prepping for paint, prime it, and then paint it. The body work has good momentum, I sure hope the motor will start moving along.

Two lanes, both slow….

Two lanes, both slow….

Around a month ago the engine-less shell was loaded on a trailer and taken to the body shop. About the same time I started delivering parts to the machine shop after deciding what to do with the engine (conclusion: squirrel away the genuine Alpina engine and build a bigger displacement, higher horsepower mill that retained the stock-looking K-Jet injection). The project was running on dual tracks, and neither has been rocketing along.

The post about loading up the engine-less shell on Stu’s trailer ended with some immediate progress: the front windshield was removed; because I couldn’t find a good used dash, the cracked one was sent off to be repaired; and a little rust was found under the rubber windshield gasket. Since the, Stu has been tearing the car apart and repairing it.

First, Stu had a bunch of holes to plug. The body had been drilled for USA sidemarker lights which had then been removed by a previous owner.

The shock towers had been drilled for a rear strut brace/battery holder that I removed (putting the battery back in the engine compartment).

And there were weird holes drilled in various places, including in the engine compartment near the VIN plate; what those holes were for is another mystery (I thought it might be for an Alpina VIN plate, but it didn’t fit the spacing of the holes).

Bits of rust – typical for a 1980s BMW, even one that spent it’s whole life in California – and other imperfections are taken care of.

The trunk lid and hood are taken off, prepped.

And painted.

And then the whole body is stripped and prepped. And someday, painted.

While all this was going on, I began delivering parts to the machine shop. The guy I’m using specializes in 4 and 6-cylinder air-cooled Porsche motors, but he is the shop used by one of the local vintage BMW specialty shops. I loaded much of the parts in my Porsche and brought both the forged M20 turbo-diesel crank and a bin of many other parts (custom pistons, clutch, forged rods, etc.), and the Schrick camshaft.

The block and head are already there, as is the intake manifold, which needs to be bored to match the bigger ports in the 325i “885” head.

Both of these track are going forward, but the progress is slow.

We interrupt your regularly scheduled program

The motor is out. The rebuild decisions have been made, the path mapped out (mostly, more on that later). It’s time to focus on the body and interior.

While the car languished, waiting for my motivation to remove the motor, I tinkered with the body, interior, engine compartment and truck. For a while, I went back-and-forth on whether to paint the car. The clear coat was peeling off on much of the horizontal surfaces, way beyond patina. It was kinda cool. My wife encouraged me to leave it alone and I was tempted. My prior projects have only been mechanical restorations and I really like a driver-quality car with new mechanics. But the condition is way-worse than driver-quality and I do have a friend with a body shop.

And there were a lot of things I wanted to do to the car; one was take the battery out of the trunk and put it back in the engine compartment where it belongs. Sometime ago, by some owner a while back, the battery was moved to the trunk and the battery tray removed from the engine compartment. If the car wasn’t an Alpina, and just a nicely modded vintage BMW, I’d probably want the battery back in the truck. But, given my philosophy with this project, I wanted to keep it’s appearance stock. And the engine compartment needed some other work: wiring was messed up, the compartment was dirty and had a bunch of things added (like a now inoperable cruise-control), and there were several little holes drilled for various little things. And the car had air conditioning, which I don’t want (ironically, I removed much of it while reading Rob Siegel’s articles about installing a/c in his 635csi). These little things were too much for me and I needed a professional to weld up the little holes, replace the battery tray, etc. So, while it’s at the body shop getting that done…..

Once the paint decision was made (some might say preordained), the slippery-slope kicked in. The windshield needs to come out for the paint job, and the dash is cracked…. The car was drilled for USA side markers…. I could go on….

So, my friend Stu, his dog Pickles, his pick-up truck, and a friends trailer made the two-plus hour trek and we pushed the motorless Alpina on the trailer in-between our arguments about politics.

Suddenly I had an empty parking spot in my garage and Stu and his crew had a rough 1982 shell in the shop. Windshield out revealed a bunch of rust in the bottom corner, under the gasket.

Dashboard removal revealed a banged-up heater control panel and JB Weld holding parts of the dash together. Stu already sent the dash off to Justdashes.com, where it will be returned to prior glory (I tried to find a good used, crack-free dash – but no such luck).

The gauge cluster, which looked fine installed in the car, once removed, looked like it bobbed across the ocean on the way over from Germany.

Each day, it seems, brings a new revelation.
