Technical Support / Re: C9 400 HP Excess oil from breather tube
« Last post by Frank Bergamo on June 19, 2024, 03:36:14 AM »
Overfilled crankcase will push excess out breather tube. Next oil change, put the exact amount of oil that the spec calls for, then check dip stick and mark the level with a file to calibrate dip stick. It is common for the dipstick to not be accurate, as the dipstick is installed by the coach manufacturer, not the engine manufacturer. Hope this helps.

Shop that knows the system, most of the buses of this era were built in Eugene / Coburg. Can’t find any shop in the area I’m comfortable with.
Technical Support / C9 400 HP Excess oil from breather tube
« Last post by Bryan Beamon on June 19, 2024, 01:03:23 AM »
After a 160 mile drive today found oil on ground from the breather tube and minor amount on the tow shield. Checked oil level and it was 1/4 inch over filled but had been that  level since last oil change at 1000 miles ago. Coolant level was full and hydrolic  fluid level full. Any ideas as why the oil leak from the breather tube was excessive?

Assuming that your coach is equipped with a power water hose reel you won’t have a standard city water connection with a built-in check valve. Open the access door inside the wet bay, look to the right of the hose reel and you should see the freshwater check valve. I’ve attached an image showing the location on our PT.

Another thing to consider, if your coach has the full version Aladdin (shows the status of the freshwater tank) the autofill function uses the tank fill level to know when to shut off. Are your tank level readings accurate? If not, you will need to recalibrate your tank levels. When using the autofill, you should see an ‘AF’ indicator on the freshwater status line, does the freshwater tank continue to fill after the ‘AF’ indicator turns off? If so, then your problem is likely as Eric explained.

Sounds like two separate issues
1) there is a check valve and pressure regulator built into  the city water connection it sounds like the check valve is failing to prevent back flow.

2) the red hat valve is responsible for filling the fresh water tank if it doesn't close the tank will over fill and water will run out the overflow/vent

check the valves to the outside shower
if you were using it and shut down the water at the shower head instead of the hot/cold valves you could be back flowing through your system
Same with your shower head on your inside shower IF there is another shut off valve inline on the line after the faucet nobs

On my 2002 Marquis the porch light problem was the switch under the light.  Jumpered the switch and I saw the light!

The step/grab handle lights & porch light are on different circuits.

The porch light and map lights are on the same fused circuit, it is labeled MAP LTS.

Do your map lights work? If not, perform the following.

Turn the ignition to run and the porch light on.

Front Run Bay.

PCB14, check the 15-amp fuse labeled MAP LTS, the associated red LED should be illuminated (if the ignition is in the run position), if the LED is not illuminated fuse is probably bad. If the LED is illuminated check the connector on the circuit board.

If the porch light still doesn't work check the green LED on PCB1 labeled RELAY OK PORCH LT. If the LED is not illuminated, you may have a bad relay on PCB1. If the LED is illuminated check the connectors on the circuit board.

Please report back your findings.
