1030 oil leak

MattLF9 · Sep 14, 2020

My 1030 all of a sudden started leaking engine oil out of the #1 exhaust port.

Everything looks good on top, no visible cracks, valve guide looks good, no vertical crack.
Has anybody experienced an issue like this before?
Is the guide pressed through an oil passage on these heads?

Thanks for any help.

Forgot to add, the engine doesn't smoke at all, no blue haze, runs perfectly clean.
I have practically no blow by, no loss of compression on that cylinder either, no knocking to speak of.
Just a little over 100 hours on a major overhaul, heads are crack free remans.

Sounds like wet stacking to me. Diesel exhaust temp is much cooler than gas engines at idle/light load use. Try working it harder, I'll bet it clears up under heavy load.

I'll give it a shot and see what happens, but it doesn't smell anything like fuel.

Use an infrared thermometer and point it at each exhaust port. The coolest one would be suspect to a bad injector.

IR thermometer shows even temp across all 6 cylinders.
I pulled the #1 injector, pop tested at 2175 psi, very little leak down.

This has been the best starting 30 series tractor I've ever had, starts right up like a gas at 50°F.
