| + | ===== Test with air cleaner removed ===== | ||
| + | The A/C was removed to see if it had any impact on crankcase pressure testing. \\ | ||
| + | There was no noticeable difference with it off through the RPM range tested up to 5000. \\ | ||
| + | There was also no noticeable oil mist during this period. \\ | ||
| + | Condensation and light oil mist accumulation at the bolts was from original testing before replacing the umbrellas. \\ | ||
| + | But none of this is was in the filter and no oil puking. \\ | ||
