smoke from valve cover breather

when i turn on the enigne, there is a lot of smoke that comes out from the breather, it looks like my car is blown up why is it doing that? and the timing is right, but the valve adjustment is wrong, will the piston damage the valve still?

Ok so you replaced the head gasket recontly right. If not what was the last thing you did to the motor before this happened.

yea, i just replaced the head gasket, and it looks like the breather is a 2nd exhasut.

oh, and i adjusted the valves, i think i did it right .08mm on the intake valves and .15mm on the exhaust. and the timing is right on the red mark on the crank.

Excessive crankcase pressure is caused by 2 things-a non functioning PCV system or compression leakage by the piston rings.

ill check the pcv valve, i broke it when i changed the head and i got a new one. how do i check if its broken or not?

Take a pair of pliars and gentley pinch the hose that connects to it and see if you hear a click noise, if no nosie then it is likely bad. Remove it and shake it back and forth and see if you hear a ball moving inside, if not then it is deffinatly bad.

the pcv valve is ok, can i just take a hose and t the pcv line and plug it in there?
