gurus, kindly enlightened me on this. my brod is currently using my car. he had change oil last month and his mechanic recommended using oil treatment, on which he cant remember the brand. yesterday, i check the car and noticed there is gas pressure coming out from the dipstick tube. occasionally, may tumatalsik ding langis na pa kunti-kunti. i immediately advised him to changed oil. malabnaw talaga ang oil na nagamit nya, i suspect it is due to the oil treatment. i asked my mechanic on this. it may be blow by, but there are also cases, according to him, its normal even for new engines to have blow by. by the way, the car is isuzu crosswind XT. does it mean, my engine is dying?
