Oxygen sensor safer rtv sealant
Do not install the oil seal dry, pre lubricate the oil seal lip with engine oil or vaseline

done replacing, I brought it on a nearby mechanic

here's what they did.

1. removed compressor, ps pump and alternator belt.
2. remove fan
2. removed some cover, based on manual its a rubber noise cover ...
3. put a socket, i forgot the number, they did not removed the radiator
4. put the gear to engage mode and hit the brake, then turn the socket holder ( facing the bolt of pulley - counter clock wise turn with tube holding the power handle of socket), i think they did the gear engament and brake to lock the crankshaft and so the pulley bolt can be loosen. - it work.

- then after oil seal in place, and return everything, run the engine and observed. there is still a leaking, but not on the oil seal, instead on the portion of the gearcase cover, they said that there is an o-ring behing it and might need to be replace.. well, at least I know what is the problem i am going to attack next.

Socket to use for the pulley bolt of 4Ja1 is 24MM. Just to record.
