Question Oil coming out of the dipstick!

Hey Guys,
Maybe one of you can help me with a question. I have an 01 dodge 24 valve and yesterday it started spirting oil out of the dipstick bad and smoking white after I fueled it up. I know its not the puke box plugged up, because i checked that. Is there any other places I should check for maybe crankcase breathing? Or am I going down the wrong path? I took the oil cap off and its puffin out the valve cover? It never got hot or anything, what is going on?? It only has 310,000 on it.

High crank case pressure is caused normally by to much oil in the base not allowing the vapors to vent back to the front cover. Other things are the turbo can vent air from the compressor side to the crank case. Valve guides can leak air into the crankcase or you could have a piston scuffed and putting air into the crank case.
Your oil pan level should be 15 quarts / 14.2 liters. That is the level to the full mark.
To check the turbo, you have to isolate it and pressurize it to about 10 lbs, and if it vents into the crankcase it needs repair.
Pressurise the turbo outlet and that will test the valve guides for internal leakage, and if you release the pressure and turn it you can also find the cylinder.
The cylinder you can remove the pan and look up or remove the injectors and do a cylinder leak down test.
Just a thought!

Would the ehote smoke coming from the exhaust due this also the puffing from the oil filler cap?

If you have white smoke coming out the exhaust then you can remove the exhaust manifold, and see which cylinder it is, look into the turbo turbine to the ends looking for damage. Cut apart the oil filter and look for piston aluminum.
Then you have decisions to make.

Someone said it could ne fouled injectors. Will that push oil out the dipstick? I know it will cause the white smoke un sure about the other.

I have done a lot of these engines and changed very few injectors, if one has blown or cracked a tip it will smoke a lot but if you are already getting the puffing from the breather, it already has damaged the piston. You need to test it and fix it.

Hey John,
Thanks for the info number one. Number two since I am waiting for the compression check guage, now coming on Saturday, how would I check the vaccum pump and turbo?

The turbo you have to block off the intake and use the plug for testing the CAC pressurise the compressor housing to about 10 lbs.
The vacuum pump I do not know I worked on trucks that did not have them.
If you are going to pull all the injectors and do a compression check, I would recommend a cylinder leak down test it will give you more information, and is a lot less mess.

Johnp3, I finally did a compression check and the 1 piston only had 100 on the reading. The others were over 300 varying a little. Could this be a valve seal, ring or head gasket?
