Parts cost is cheap, so let's change it.
Since the vehicle is old, we changed the oil pump seal and other parts while performing OH on each part of the vehicle.
It is not available from Manufacturer only in this part here, but you can buy it only in this Seal.
Worst case scenario, the Engine breaks, so changing a part that costs a few hundred yen makes a difference in my mood!
If you haven't done Engine in a while, you should change the vehicle with the White Smoke Moke Moke.
It is not a difficult task if you can bleed air from the oil pump.
Rakuten's webike has a high shipping cost, so if you plan to buy this much, buy it from here! (Lol)
