dipstick blowing out

[wull]

hi was out in my evo 4 the other day and while accelerating from 30 to 60 in fourth gear the dipstick blew out and sprayed oil all over the engine bay
have checked breathers on cam cover are clear and done a compression test and im getting 12 bar on all 4 anyone any ideas wats causing this

seals gone on dip stick , very common .
just crimp the pipe by a few mm ,wont blow out no more

ino ther quite bad for tht but shouldnt b blowing oil out should it

It could be the o rings on the dipstick that have gone weak but on a E4 chances are the ring lands could be on there way out its quite common on them.

You need to get a cylinder leakage test done not a compression test.
