Interesting thing the overhaul shop had provided ground test reports that included the fuel pressure at all RPM's
Folks,
Apologies for what is a bit of thread drift, on my occasion the engine was a bit bigger (P&W R 2000) as was the engine overhauler, who shall remain nameless, but it was not QF.
Come the day, said engine was hung on the wing of a DC-4, and out they went for an engine run.
The numbers were a bit off, so back they came for a change of plugs.
Next time, still the same "bit off", so back they came and this time they did a compression check. Low and behold, there was nil compression on one jug.
So, off came the rocker caps, but everything looked fine there, so off came the jug, whereupon the cause of the lack of compression was was very obvious.
There was a complete absence of a piston and link rod in said cylinder.
Despite the test cell run sheets having all the numbers within limits-just!!
I suppose you could say that, at least they got thirteen out of fourteen right, so it was only one fourteenth wrong, which was about average for said org., which went out of the big engine business not long after.
Tootle pip!!
