This is what is called 'blow by.' Changing out the PCV will help this out. Change the filter as well. I assume this is a higher mileage vehicle. You might want to pull the intake and clean all of the carbon out of the valley. Better gas/performance will be a result.

Like this one depend upon the year.

The PCV valve connects the crankcase to the intake manifold. Ask your mechanic he know's exactly where it is.

PCV means positive crankcase ventilation.
It depressurizes the crankcase from normal and abnormal blowby.
Without this, pressure will build up and will find an outlet to release and the weakest exit is the front and main oil seal.

hi, Once na makita mo na yung PCV, better check mo na. hipan mo yung dulo na galing crank case, (see picture from v6dremaer) ayun yung kulay itim. one way valve ito. Dapat may lalabas na hangin sa kabilang dulo, pag walang lumabas ibig sabihin nyan sira na yan, kung hihipan mo naman sa kabilang dulo (grey) wala dapat lalabas na hangin sa kabilang dulo. Kung bibili ka ng PCv, chk mo na rin yung rubber socket na pinagsasaksakan ng PCV, COST could be around less 300 pesos (PCV & Rubber socket).

replacing the pcv might work but it's not a surefire solution to the problem. minsan the engine is just on the way out na talaga due to age and neglect.

try the pcv muna and see if may oil pa, if meron pa then you know what needs to be done

lowrider17,
in my opinion, wag mo munang ipa-overhaul yang makina mo. i'd suggest ipa-change oil mo na lang. first use flushing oil para tanggal residues sa loob ng makina mo. tapos ma-drain yung old engine oil mo, use a 20w-50 engine oil and a can of Pertua. ang level lang ng oil sa dipstick ay should be only 3/4 of the marker, 'wag mong ipaabot sa "F" or full.
