The previous owner had upgraded the engine to a 1948 super eight 5 main bearing 327 cu in eight cylinder engine. Original was a 282 cu in engine
With the car lying out in a yard open to the elements with its carb missing water had entered the inlet manifold and completely ruined the innards.
It was a nightmare prying the pistons loose as the rings had rusted into the sleeves causing a bad jam. The valves were a complete mess and some had corroded to wafer thin
It took me days to gently ease the pistons (I had to save them) and after loads of WD40, kerosene, diesel, thinner finally managed to remove them without damaging any
Once I had the entire engine dismantled I carted it to a machine shop to have new sleeves put in, new valves cut from truck valves, new guides, crank journals polished to new bearing sizes (luckily I had new bearings). The gudgeon pins were a problem so ended up hardchroming them and having them machined to spec. The pin bushes needed renewing, so I had fresh alloy metal cast to spec and new bushes made.
As I had the manuals I was able to work on the engine as per Packard recommended tolerances
The engine shop hadn't seen a petrol straight eight in years so the owner himself wanted to machine it with pride. That was fun watching their excitement. Before the machine work the water plugs were pulled out and the block chemically washed to remove all sediment.
Once the block work was done, had new studs made (originals were weak and corroded), had both head and block surfaces machined and she was all ready to go home. Once home I painted the block and head in Packard green and started the assembly process. At the machine shop I had made sure the pins were a push fit by boiling the pistons and also the liners were lapped and honed keeping the recommended clearances in mind. It was great fun assembling the engine, went about meticulously following all the torque specs, no chances taken!
The Packard engines had a balancer up ahead of the crank that was basically a circular weight encased in rubber. This was meant to work as a shock absorber and was critical in making the engines silken smooth as it ironed out vibrations.
Obviously the balancer rubber was as hard as wood so had to dismantle the contraption and with a great deal of persuasion and planning managed to make the moulds and convince the rubber guy to mould fresh rubber renewing the balancer to like new.
The oil pump facing was okay so didn't have to fiddle with that.
From the junk that it had become, bringing this magnificent eight to this level was a very satisfying journey. The engine was now assembled.
