Decided to bring the car back to its owner the other day. Went to the Farm in the morning, started the engine drove out of the shop, boxer starts smoking. If I had a gun, let`s say an AK-47, at this moment I would have taken it and emptied a couple of magazines into the engine bay.
Removed the exhaust pipes and found water in pipe of cylinder 1. Removed the lhd head and found water in the chamber, too. All clear, head cracked. Ordered new head gasket, prepared the best of the remaining rotten spare heads and installed it. Started the engine, no smoke! Hurray! Two days later, one test is no test, started the engine, white smoke! At that point I would have taken the AK for myself if I had one. Two tests is no tests, tried again a few days later, holy white smoke, habemus papam!!! The other head down as well? That can┤t be true. and no more usable heads around. Ordered one from classiclancia.com, never give up!!!!
Dismantled the intake manifold put it on the workbench and wondered why it would not lay flat. Due to whatever reason it had twisted so that the two ports where not in one plane any more. For this reason one of the sides would not seal, depending on my sequence of bolting. As the manifold contains water channels, the water could run into one of the inlet ports.
Is there any lesson to learn?
I need a gun!
Why the story? Today I drove the Flavia home, end of a mightmare!
Time to go on holiday

Rather exciting pressing those pistons out.
My Spider had sat for thirty years (almost typed thirty tears...), and to get the crank out I had to hammer out the rods, pistons, and liners also. At least the 4th Series liners are "slip fit" to the block, but they still didn't want to move easy.
Pressing the last/worst piston took a similar force to exit the liner, 9 1/2 tons, and broke loose with a similar explosion. Really makes you jump! In my case, the major corrosion was the aluminum pistons, especially in the ring grooves.
Which chamber matches the rod? With all that corrosion I wonder if a leaking gasket filled the cylinder(s), and it hydro-locked, bending the rod.

hello Hubert, can it be that the cause of the disaster is the rubber rings?
it may have reduced the lubrication, it blocked low the valve and hit by the piston the connecting rod is bented

Pulled, or better say pushed the pistons today. Had to apply 10 tons in minimum to get them moving. But then they jumped a few mm with a loud bang.
There is always something new to be detected. In this case someone had the idea to reduce oil consumption through the inlet valve guids by putting handmade rubber quad rings on the valve stem. Wonder if there was a measurable change.
The combustion chambers require some welding
Not clear what bent the conrod

wow, data overload for sure. i always love to hear what people that really know their stuff have to say. i try to just keep my own mouth shut and soak up as much as i possibly can.
that conrod, isn't that lancia design?

Today my friends from classiclancia.com and Werner from ARICAM high performance gaskets dropped in to have some serious technical talk about the head gasket in particular and engine testing in general. Werner had been managing the testing department at Goetze for more than ten years. Goetze, now part of Federal Mogul, had been the # one supplier of piston rings with a market share of more than 80% in Europe back in the time of our Lancias. Werner just touched the piston ring issue, yet left massive info about this. You won┤t believe how much know how is in there.
He also gave some advice about the test stand, but honestly that was high on the professional side. Ventilation from below and front, suction from above, cutout with differencial rpm control, temp controls for both exhaust lines, torque compensation for the engine frame, cutout with overtemp control, new digital controls all over . . .
But we also talked deeply about the head gasket. We inspected the common aftermarket stuff which I got from the traditional sources, detecting quite some imperfections. Received so much input on the lining of the cylinder bore, how the pressure bores of oil openings and water openings have to be made, how the main bore has to be designed and so on. Again, so much know how that makes the difference between a high-end product and a simple look-a-like. We are considering to transfer the knowledge coming out of the 3.0l project to the standard 2.8 and 2.5 engines to make gasket sets according to German standards.
My friends are discussing the head gasket
Note the conrod
