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?

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.

Re: smoke from valve cover breather
Excessive crankcase pressure is caused by 2 things-a non functioning PCV system or compression leakage by the piston rings.

Re: smoke from valve cover breather
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.
