How to deal with oil that always leaks even though you repeatedly replace the Supra X engine seal 

How to deal with oil always leaking into the left engine block of the Supra If oil keeps seeping on the left side even though you have replaced the starter siel, front gear siel and front gear siel, there are several factors. 1, the seal is leaking, there is a possibility that the installation was not correct, namely the seal pressure spring came loose during installation 2, worn crankshaft, worn crankshaft can cause oil to always leak even though the seal has just been replaced because the grip between the seal and the axle is not normal 3 bolts 10 of the keteng chain tensioner retainer are leaking 4, engine breather plug If the engine breather blockage is very fatal and interferes with the engine's durability, the engine is hot because it doesn't breathe in cold air and releases hot air so the air settles in the engine and pushes all the seals and gaskets and then releases oil. @mandirimotorst
