I had made a cruise
from Galveston Bay to Lake Ponchartrain to visit an old friend. I ended up staying in Madisonville for 2 months.
I was doing maintenance
on my cooling
system when I noted a crack in the base of one of my engine
mounts. I bought 4 new mounts but only replaced the cracked one. Duty called and I headed back to Houston
on the spur of the moment.
I ran most of the way on the engine
. On my arrival I found that I had developed a fuel
line leak. I replaced a couple fuel
lines and found another leak on my injector pump
end cap. This turned out to be just the gasket
. (A square sided "O" ring)
After bleeding the system and running the engine I found that i still had a small leak to the tune of 1 drop every 45 seconds of so. This leak continued despite the engine being stopped. It increased a little when running but not a lot.
I continued to look for the leak while working on other projects. I replaced the other engine mounts and re-aligned the shaft coupling. About 4 gallons of diesel
had collected in the pollution pan in 3 weeks.
After chasing the leak again, I had just about decided to pull the pump
but decided to look at the pump
breakdown diagram again. I noticed bolts for the control cover were a might camouflaged by be multi-purpose. A 1/2 turn of the wrench and leak is no more.
I am convinced that vibration was the root cause of my leaks
. The old Perkins
runs smooth for now. Knock Wood.
