O2 sensor cables were not secured at all....


Somewhat the oil pan looked too flat. Probably someone used the jack to hold the engine. Big no-no without wide enough attachment as it will dent it.
For now, it is not enough to cause oil pressure issue so going to leave it.





Both drive shafts were making clicking noise and the right inner joint was just about started leaking the grease.




There were lots of ABS error code stored on the controller but all of them were related to the FL and RR w/speed sensor.
FL one looked to be replaced in the past but not the RR one.

The owner actually told me that he saw ABS warning light on the way to my place but when he stopped and started the engine again, there was no more warning light.
Looks like some of the codes were not erased after the FL sensor was replaced.

Later, after reading the code, reset the ABS controller using SCS terminal, IG SW and brake pedal then carried out another test driving session but nothing happened so not sure which one was bad but very likely to be the RR one with noise issue as none of the code triggered the TCS warning light and FL one was already replaced.





Speaking of wheel speed sensor.....
I found that the FR sensor was not installed properly and the cable was allowed to touch the coil spring.
As it was left for many miles, the cable sleeve was scratched. No error code so not enough to damage the shield but one thing to keep eye on it.






Wrapping time......






Found that the Rear IG coil cover was installed at the front bank and vice versa. The rubber gasket was sitting at the lower side.... Not good.
So, it was allowing water to enter under the cover especially at the rear bank.
Checked with the mirror before lifting the IG coil and no moisture or huge debris.
Will install them at the correct position later.





Found out that the IG coil harness guide was broken in two pieces....
Will replace it with new one. I hope it's in stock in Japan as I never had to order one in the past so very rare parts....
