engine failure

I recently acquired a 1973 P337 Skymaster and had a bit of trouble with
it on a flight to New Jersey when I lost an engine enroute. I left
Magnolia Arkansas in the morning and flew to Knoxville for lunch and
refueling, then on to CDW --Essex County, New Jersey. Over Allentown,
I noticed fluctuations in manifold pressure on the front engine and
rough operation. The EGT and cylinder head temps were fine, but my oil
pressure was down to nothing, so I shut down the engine and feathered
the prop. I called ATC and let them know. Then I flew the plane on
towards CDW keeping a close eye on the rear engine guages. Since the
engine is turbocharged, I had no trouble holding altitude on one engine
and therefore decided to continue to my destination (about 15 min
more). When I arrived at CDW, they had men and equipment waiting and
let me use whatever runway I wanted. I chose 22, entered a right
downwind, and put my gear down. But it wouldn't go down. So I circled
and pumped it down. Then no gear light came on. I tried to call the
tower, but I had lost all electrical. (Hence the gear light failure).
So I lined up on final and landed the plane.

The mechanic at CDW looked everything over the next day and reported
the front engine had blown an oil seal for one of the cylinders, and
the rear engine's alternator was bad. In addition he said the fuel
line to the rear engine had eroded through and there was a gas leak in
the rear engine compartment. He noticed this because of a leak of gas
on the hanger floor. I swear there was no leakage of gas under the
plane prior to the trip. So I had three systems fail in one leg of the
trip.

The plane was one month new to me. I had 30 hours on it since
purchasing it and had fortunately practiced single engine landings and
manual gear extension. For 30 hours there was no excessive oil
consumption or leaks or ther signs of trouble. So it's hard to blame
the mechanics who worked on it last. Just fate I guess.
