I have a Perkings 4-107 in a 1974 Seafarer Ketch
. The Perkins
, while noisy and leaky, has always started on the first turn of the crank, doesn't overheat, and is very fuel
efficient. The oil
line that runs down to below the injector pump
recent burst, spewing oil
every where. Engine
still had oil pressure, but I heard a knocking so killed engine
and discovered problem.
Replaced the oil line and oil, but engine didn't start right up: took 4-5 seconds to start, very unusual for it. After a few seconds, knocking stopped, but then redeveloped 10 minutes later. Killed engine, checked everything, and restarted: same thing, it took a bit to start. It then seemed to idle rough and then died at normal idle speed. Ran for a few minutes and a very loud knock developed. Haven't run since.
My question, is the knock the engine or the injector pump
? I've rebuilt many car engines, but never had any experience with an injector pump. I don't think the engine was without oil, even though pressure was very low, but line to below injector pump was not delivering oil, whichever direction it goes.
