I have a 96 300ex bored out to a 314 with an 11:1 wisceo piston k&n air filter, sparks header, and a 250x cam. the oil level is ok but it keeps blowing oil out the engine vent tube. this has happened before and we recently overhauled it to try to fix the problem and it still does it. and anyone please help me i need to get this problem fixed once and for all

Sounds like compression is getting into crankcase. Do a compression check.

Yep, had that happen once, it sucks :)
do a compression test. I forget what my compression was,or i would tell ya, ill go and look here tommorrow.If it has low compression ,tear it down(yeah i know, it sucks)and find out if its a cracked head, a headgasket, or whatever. Tell us what you find out.
