Didn't like the level of corrosion at the brake banjo bolt so replaced both RR & RL ones.
Bleeder screws were fine at all four corners so just re-used them.
As we are not replacing the Brake master cyl, very important to use the pressure bleeding method.
Otherwise, you could destroy the old master cyl if you use the old text book method of pressing on the brake pedal.
Due to the effect of the white balance of the digital photo, not easy to show how dirty the air filter was.
It was almost like black. New OEM green one to be installed.
As reported earlier, disconnected the suspicious fuse from the wires hidden under the side sill pad.
New clip at the rear upper trim athough the fixing point was already damaged so I have a feeling that it will come off again.......
Compression check after the Eng Refresh.
Interestingly, the data from all three cyl at the rear bank were almost exactly the same as the ones measured before the start of the service.
However, the front cyl were dramatically improved by carrying out the Eng Refresh.
Normally, it's the rear bank that people tends to make mistake due to limited space.
Very happy with the result but already expected it when I fired up the engine with the rhythmical sound.
The owner will receive the full data through email later.
The missing spacer under the IG coil cover. Without this, the water can enter behind the IG coil cover.
New Rear IG coil cover and applied silicone grease to the gasket on both covers.
Adjusted the base idle rpm and checked the IG timing as well.
If your engine is properly adjusted and tuned, it should be able to idle even at about 600rpm. If it stalls, you have some sort of problem.
Already knew someone touched the idle air bypass screw as there was no locking paint.
Sealed it with the liquid gasket.
