Hi Folks,
An oil and filter change today included the following:
1. Rerouted and secured the red water hose so it was not in the way of the oil filter (engine clamp reversed to raise hose about 1.5" and plastic tie wraps added to secure transmission signal cable in the area of this hose).
2. Prefilled the oil filter with about 3 quarts of oil.
3. Drained oil for 5 hours - about an extra quart was collected.
4. Added 3 gallons and ran engine for 1 minute, then verifed 3 gal mark previously filed on dipstick. Note - Coach was leveled first.
5. Added another gallon and verified the 4 gallon mark.
6. Added 3 quarts and verified the associated mark.
7. Added the final quart and verified it aligned with the full mark
which equals 20 quarts or 5 gallons. This is the required amount for the ISC330 (year 2000).
Why all of this? There has been many threads on improper dipstick length and in addition ruptured dipstick housings. Note that the engine takes 20 quarts and the filter 3 quarts. Inspection of the dipstick housing is a good idea during an oil change.
Addition note - a 1 pint plastic bottled is fitted to the blowby hose and it had 1 oz of oil in it after the last 5000 mile trip - the pac brake butterfly valve did have its holes enlarged some time ago.

Fred,
Many thanks for the oil/filter info. I will pay much closer attention the next time my CC gets serviced!

Fred,
Would you explain what you mean about enlarged holes in your pac brake.
Thanks

Hi Vaughn,
The pac brake has two holes in its butterfly valve to let some exhaust through when activated (closed). When activated, back pressure causes a higher pressure and turbulence in the oil pan and oil exits the "blowby" vent and hose located between the oil and water filters on the ISC 330. The holes are enlarged to reduce the pressure and therefore reduce blowby. There is a loss in slowdown.
