Crankcase engine Fault Please help

[kpretro84]

Hi i am with small port 1600 red top 4age engine.

starts fine works well still in process to run it in since it's a rebuilt.
anyway....

Has anyone had a problem with the engine breather pumps heaps of air out?

turned off the engine i could actually hear some air noise seems to be under pressure. ive also noticed oil leaks its forcing oil out the engine through the dizzy and on top of the can covers.

i unbolted the dizzy to check if seal is in good condition as soon as i removed the bolts the dizzy got pumped out? what causes such things?

someone must have had this problem i would like to know what was the problem so i know if i have to pull the motor out or not

Any feed back would much appreciated
