Alfa Romeo Milano Verde Part 3: Rebuild

I get the idea that foreign or classic car owners on the coasts often have “a guy” to help them out of trouble when things start to fall apart.  For instance, my dad, when he was piecing together his 1973 3.0 CS, had most of the work done at shops within a 15 mile radius of our house in York, PA.  To have the carbs tuned, he sent the car down the road to the shop with plenty of Alfas out front.  For upholstery, he commissioned a shop downtown with a slew of Grand Wagoneers in the lot, and, at one point etched into my memory, a Watusi bull in various stages of meat grinding inside the shop.  To get the brakes ready for inspection, he dropped the car off behind a trailer park, close to the river.  He kept the car in shape without ever leaving York County.

Living in Columbus, IN, undertaking an Alfa V6 rebuild posed some geographical challenges.  The only European shop in the county was the local Import Auto shop, where I buy all of my VW and BMW parts.  So, for ignition and fuel system components, I had the convenience of stopping by after work to pick up parts.  I asked around for recommendations on local machine shops, and drove south to Jackson County, where I found a shop for head work, and a shop to take care of the bottom end.

Alfa Romeo Milano Verde Part 2: Disassembly and Diagnosis

DSC_4183

Continued from Alfa Romeo Milano Verde Part 1: Introduction

Understanding why the Milano’s engine had seized so suddenly and ruinously on I-70 required minimal disassembly.  The first bolt revealed metallic sheen of the oil – not good.  17 bolts later, I was staring at a mangled connecting rod cap sitting in a rubble of rod bearing annihilation – oh no, crank is bad.  Then I noticed the coolant lingering in the lower oil pan, and started feeling better knowing that at this point, at least I’d get to meet another Alfisti, because the block was toast.

Now, the root cause of the spun rod bearing and subsequent destruction is more difficult to establish. 10 minutes prior to the excitement, I had checked the oil level, so oil was available, at least to the oil pump. The oil pump seemed to be working too, since the low oil pressure light never came on, and the oil pressure gauge never dropped.  Some cavitation damage was present on the oil pump rotor, but given the adequate oil pressure, not enough to blame for loss of oil film.  The oil itself was in good shape, having been changed 700 miles ago.

A.L.F.A: Always Looking For Another

Only in my case, it would be Always Looking For Another Because One Broke, or ALFABOB.  I imagine somebody already has the as a personalized plate – likely in California, where extroverts seem to thrive.

Now, I’m not the first person to experience a broken Alfa, but both my ’89 Milano Verde and my ’95 164LS both have experienced bottom end failure within their first weeks in my garage.  I am documenting the Verde failure and rebuild, but to summarize, it threw a rod while I was doing 75mph on the Interstate.  Since I missed it so much, I bought the 164LS to have something over-the-top to shuttle me around in while the Verde engine is on the stand.  Well, the 164LS developed rod knock while driving at 55mph on the highway.  Luckily, it will only need new rod bearings, which I can manage to replace with the engine in the car.
