Breather

[n144sh]

X3 + on Vetterman exhaust. 1200+ hours on the Vetterman on my RV-4, 70 hours so far on the muffled 540 Vettterman on Bearhawk. All trouble free. Building a robust exhaust is a bit of an art and these guys have it figured out. Highly recommended.

I wish I could have talked them into making a muffled system for the 360, but with our odd arrangement of angle valve cylinders and the offset carb Clint didn't think he could do it. I have respect for a supplier who knows his limits and will say no before compromising quality of the final product.

To add a data point about the breather, I have mine oriented to drip just above the exhaust pipe. I end up with a little oil on the belly, but it's certainly manageable. It seems like I clean it about 3-4 times a year. I run the 360 with no more than 5 quarts on the dip stick, and add oil at 4. I calibrated my dip stick by adding a quart at a time and marking the stick, so it only indicates the level of oil in the sump. I speculate that there are about 6 quarts in the engine when the dipstick indicates 4, considering the oil cooler and prop and all.

Clint built my exhaust. I gave him the dimensions he asked for and the exhaust fit perfect the first time. I have talked with them since my purchase about possible modifications and they have shared the pro and cons of my ideas. They have been a great source of information. I appreciate his input on this group and highly recommend them.
