p38 blowing oil up dipstick
hi ,i have a 1998 p38 2.5dt.at 3000 rpm oil squirts out small hole at the top of the dipstick.
oil level is ok. have changed oil,filter, cleaned all hoses,cleaned rocker cover breather.cleaned mesh under rocker cover,and have looked for egr valve which i dont seem to have being 1998.
would anybody have any suggestions as this is beginning to get to me.
also if you put your hand over the breather hose on rocker cover it squirts oil out.
would it possibly be rings ????
hope somebody can throw some light

You checked all of the things that I would have. To get oil out of your dipstick there must be a huge amount of pressure building. The biggest thing would be the PCV valve. If that can't handle the blowby you might have some serious problems. Does it seem to run ok with normal power? I think you need to do a compression test and a leakdown test. That should alert you to any problems with your rings/pistons. You could also try temporarily pulling the breather hose off the valve cover and see if that changes anything. On my Rover I had a breather hose that became creased at one of the bends and bocked airflow. Might want to check for that.

thanks Chris
have ruled out head gasket asno loss of water ,no oil in water or no water in oil.not overheating,and power is as normal.
I am doubtful if it is rings ,as it does not burn oil,and i can only presume if it was it would have gotten worse as time went by.
I hope it is something blocked,and really like to think of pcv valve.however i am no mechanic and perhaps you can guide me to location of this ????
you also mention taking off pipe on valve cover,is this the breather hose on rocker cover ?
many thanks fitz

Sorry, thought it was a V8. I would check your compressions, if they are low, that is probably the problem right there. As the pressure would leak into the crank case and cause oil to spray. It could be a worn block or worn piston rings like Krazz said. Check your compressions and then go from there. BTW, how many miles are on your rover?
