I'm working on a 2013 Leopard
48 and trying to help the owner figure out next steps for his generator
- Northern Lights
OM773LW3 with 8,940 hours on it.
- The owner reported that previously the dipstick would pop out causing oil
of course to escape and go all over the place. He would of course replace the lost oil
yet the issue persisted.
- He bought a new, tighter fitting dipstick figuring the one there had slowly worn and that was the cause of it fleeing its post.
- Oil loss continued and eventually oily residue was found in spots along the head gasket
- Is it possible that the head gasket
was slowly failing, which caused blow by to increase, which then pressurized the crank case enough to blow out the dipstick? Is there a way to diagnose or definitely answer this?
- The fear/hesitation with moving forward with the head gasket replacement is that whatever pressurized the crankcase previously enough to cause the dipstick to pop out will just then cause the new head gasket to fail again in short order?
Tests/Notes So Far:
- Opened lower oil fill while generator
under load, don't have a manometer on board but definitely felt air puffing on my hand.
- Visible oil residue around head gasket
- Checked air filter and intake - clean, no apparent, issues, no clogs
- Checked crank case vent - clean, no apparent issues
- No milky oil
- No oil in coolant
- Has not overheated with the current
owner (though could have in the past)
- Are there any other simple tests that I'm missing prior to moving forward with a head gasket replacement?
Thanks in advance for the collective knowledge!
