oil dipstick seal

after 12k miles I have concluded that the seal at top of my 8.3s oil dip stick is allowing enough oil to cause many little speckles on rear of coach. My stick has the loop type handle not a T-type. Does this mean mine is a replacement? can I get a new seal ?

I have been having a problem with my oil do stick for a couple years now. Have not found a suitable replacement yet. Have tried two with no luck. Not a priority but something I am working on. I use rescue tape to seal the top but it is a pain as I have to replace it every time I check the oil. Going thru a lot of rescue tape but it does stop the leaking from the top of the dip stick.

Roland, go to a lumber store and ask the shipping guy if he has a roll of the shipping wrapping tape (3" wide) that you can have and just wrap the dipstick with it every time or get a cork bottle stop (wine cork?) and shape it to fit into tube and slide it down the stick and glue with silicone in place. Lots of ways to temp fix it

If you have that much back pressure check the crankcase vent system. Should not be enough to bring oil all the way up the stick,

Had the crank case pressure checked a few weeks ago tech told me everything was OK. It isn't like a lot of oil leaks out of there its just that it doesn't taker much to make a mess.

Hi Roland,

Have similar problem so I use "Rescue Tape" or silicone tape and wrap the end of  the stick in layered fashion, about ~ 21/2"  to the end, helps somewhat still some oil spots on coach rear but less that before tape.  I will have my crankcase vent checked on my coach.

Thinking about this problem,I would clean the so called slobber tube from top to bottom and if there is a screen in the valve cover clean that also.Not sure how a shop would check pressure but if they check it at idle as opposed to you going down the road
at full load there is a difference.
Roland,I will bring my ounce gauge to "Q" and check for you.

Will be interesting to check the pressure at different rpm's. In the. Meantime I will take a look at the slobber tube. But the rescue tape does a great job.

Isn't there a replaceable O-ring?
To check crank case pressure I have heard of just setting the oil filler cap on the valve cover to see if there's enough pressure to blow it off when running.

If you have that much crankcase pressure your seals would be leaking.

I have also noticed a fair amount of oil spots on inside of the  door just aft of left rear wheel. There is some wheeping at 2 places besides the small amount from the dipstick.  With all that air flow coming through the radiator fans and the A/C fan any oil drops are going to get sprayed to the surrounding area. My oil consumption is interesting in that actual levels do not drop until about 5k miles. At that point I add 4 qt. Since adding and 1500 miles later the level seems to be about a quart low from full. Not bad for a 16 yearold coach with 125k miles. We are 5k into a bucket list trip and after traversing 3 major passes up to 10800 ft I am thoroughly impressed with the coolant system and retard system. Highest coolant temp was 205 per these old VDO gauges.
After a hot day on the road I raise the engine cover and the 2 side doors to facilitate cooling of engine/compartment. Our bedroom still requires some time to cool off with A/C and after hours the area below the mattress is 80+ deg.. That area needs some new space age insulation for sure.
I can not thank you all enough for the contributions to having an enjoyable trip in this 2000 FT. We just exceeded 5k miles and expect to top 6.5 k by the end.
