Engine oil

[youngrider]

* sir speedy, how do i determine if i already have a defective or worn out valve seals? Parehas kasi kami ng prob ni threadstarter, nauubos ung langis ng wla naman leak sa engine, and wala rin smoke...

Magkano kaya if ever ang repair ng piston rings/valve seals... thanks

Palagay ko di mekaniko kelangan dito kundi detektib baka may nagnanakaw ng langis Fully Synthetic siguro gamit .
