My compresor pumps oil out of the oil dip stick "BAD"while compresor is on.

Check oil pressure.

As a test, you might try a heavier weight oil (SAE 50 diesel) to see if the knock goes away. Just drain and put in 4 to 5 Qts. No need to change filter.

i think you mean
when running the engine
the DIP STICK seal as it fits the dip stick tube end. leaks oil
this a bad PCV valve.
excess crank case pressures.... cause by not doing service on car.
or worse a very worn out engine with huge blow by gassed.
is engine miles high? over 300k? miles?
or the dips stick seal there is bad.... looking at it tells you that.

if to much oil in vehicle --not on level ground --engine running while checking oil -or not swiping stick clean before reading it these are reasons for high reading on dip stick oil pressure sensor/switch only measures the pressure of the oil

Oil pump is in the oil pan. Sensor is probably bad. should have error code in the computer. You can go to Auto Zone they can check it for you free.

Very first thing, check your oil. Even if it is a little low, when making a turn, the oil will shift and starve the oil pump making your oil warning light come on. This is a common problem on that modal Ram! My 1999 Ram 1500 would do the same thing. I check my oil regulatory, even with the oil 1/2 way in safe range on the dip stick, the oil warning light would come on when making turns. I have to fill my engine all the way up to the top mark in the safe range on the dip stick to keep this from happening. Be careful not to over fill. If this continues, you may have a bad oil pump/pick up. I would almost bet, you are have the same problem I had. Good Luck.

looks the rings are stuck.when you have head off check piston. john.

Most likely place for oil into coolant is oil cooler, the aluminum box that mounts between the oil filter and a flange that comes off the block.

what kind of dip stick??? Transmission. No dip stick as tranny is a sealed system. U cannot add any fluid or check levels. U need a special machine to pump it in. Well....actually I jimmy rigged a hand pump to refill mine after I acidentally drained it thinking I had found the oil pan! Believe it or not I am not the only one who has pulled off that ******** move.

Sounds like the engine can't breath,
make sure pcv valve is good,or oil cap is vented.
your engine is building up pressure and has no where to vent,so it blows the easiest thing,the dip stick

it is either the oil sending unit or the oil pump remove oil sending unit from the side of the block and do a manual pressure check should read atleast 30 psi if not the oil pump is bad if it does then sending unit is bad
