dip stick blew off need help
You get more compression blowing past your rings under boost. The blowby pressurizes your crankcase and pushes out your dipstick. It happens more on older motors, generally speaking, but can also happen if you are boosting at higher than stock pressures. You can band-aid the symptoms with dipstick zip ties, springs, etc., or address the problem with a second vent hose, or re-ringing your pistons 
hmm I've always watched my dip stick to see if its comes out. I've seen japanese pictures of wire loom holding it down etc. but I have never expierenced this first-hand. I run ~22-23psi daily and no dip stick popping. Weird...

Removing the PVC valve and threading in a n extra Brake booster fitting to provide a second 3/8th inch vent line helped a lot in my 2g. If you don't have an extra fitting around a 3/8th BSP to 3/8th hose barb fitting from mcmaster works, for the DSMs at least. I'm not sure if the EVO valve cover has the same thread, might be different since there is an elbow there. As Eric said, if the PCV doesn't seal well, you'll build a lot of pressure in your crankcase in addition to the normal blowby. This is fairly normal on older DSMs especially, but I've yet to have the dipstick pop out on the EVO yet (42k miles). Some extra valve cover venting and a spring and hose clamp on the dipstick tube is the usual fix.

i just bought my evo about a week ago when i took it home i checked the oil and there was electrical tape around the dip stick.i maybe thought they put it on to clean the motor and they forgot to take it off.i take it off and the next day i take the car to the track car was running fine no problems.so when i get home i popped the hood and i see oil everywhere,by the dipstick area,the dipstick was out about 2inches it was hitting the struct bar.i dont know how stiff your guys dipstick is, but mine comes out like butter is this normal. i have read other posts and people seemto have the same problem about dip stick coming out.does any body know who sells a dip stick to prevent this. mods are k&n filter,front mount with piping,3inch turboback,safc,ebc set at 21psi,exedy single,the car also has a catch can shouldnt this prevent from the dipstick popping out. thanks for any input
