Back in 2005 a group of friends and I took vintage early CJs and flatfenders across the Rubicon. Everything was going pretty well until my buddy Don Allen knocked a hole in the oil pan of his nearly original M38A1’s 134-cube F-head. We quickly captured the escaping 30W oil and gathered some JB Weld and silicone while Don pulled the pan. Naturally, as soon as the pan was off the wind kicked up, blowing dust and dirt into the bottom end of the F-head. The JB Weld cured, Don slapped the pan back in place, and we filled the crankcase back up with the oil we had captured. And the dirt? F-heads eat that up. To this day the engine is still running like a top with perfect oil pressure.
