My gear shift quality was degrading as the car gets older. At first I thought the synchro condition is getting worse but to my finding, it was the leaked clutch pump that make my gear crunches all the time especially when cold. There was no oil left in the resevoir. Shit, I've saw some oil stain at the lower part of the pump and some on the firewall but it never crossed to me that the pump has fucked.. i mean, spoilt. Silly me. And belief it or not, I've never change my clutch oil since swapping to this engine. Pity the pump never get the same pampered attention like the engine gets.
But after taking off the pump, it clearly looked like the pump has already past its' peak for quite some time. The rubber bush has went hard and swelled. Even if I took care the clutch oil, this pump eventually will fail one day, but a bit later I guess. Since it is almost impossible to get a brand new Made In Japan part with reasonable price tag for this car nowadays, an OEM clutch pump from 4G92 Wira will do the trick. Beside, the pump looks exactly the same.
The mech had a hard time to fit the new pump. Later it was discovered that the new pump was for Proton Waja. It seems like the spare part guys when asleep while searching for the pump. Soon after the designated pump arrived, the installation was quite fast. Now, the gear shift is much better. The gear grinding is still there and I'm thinking of using a lighter weight of gear oil. Redline 70W-80 again? Maybe...
