I just viewed the pic of your engine and noticed that you have what looks like a plastic/metal and fiber air intake filter. The engine preheat coil that is mounted in the air intake manifold an inch or two below the filter is supposed to ignite diesel fuel to warm the intake air. When you use the preheat coil, you may melt the filter and start an engine room fire. The fix is to get the Perkins/Westebeke air intake which is made of steel and has no synthetic filter. The current filter looks a bit melted or squished or twisted.

During the Hansen Marine diesel course, they did a maintenance demo of a 4-107 that was mounted on a pallet. To demonstrate the preheat function, they removed the intake filter and energized the preheat coil. Within a few moments, a flame about 12″-18″ erupted from the air intake. (The instructor let the fuel burn off a bit and then hit the start button, and the remaining ignited fuel was sucked into the intake and cylinder heads). Pretty scary…the lesson learned is never use the preheat coil without the filter installed, and use a non-combustible (probably OEM) filter.

The short black hose coming from the head gasket should connect to the air intake cover. I wonder is this may be contributing to your oil leaks since the air in the top end of the engine is not being extracted from the valve cover chamber? Just a thought.

Best regards,
s/v Endeavor

Was hoping to take you and the gals out to lunch or dinner. If you’re still in St. Auggie next Wednesday maybe we can hook up.
Merry Christmas.
