As seen before, I'm not a fan of the way this pulley shield is welded and also attached to the TB lower cover.
The corrosion is already started at the welded area and very little clearance around the hex key fastener that I had trouble loosening the bolt.
Will apply silicone grease around the bolt head but ideally, I prefer something with an open end fixing.
On the other hand, there was no corrosion on the AT crank pulley so going to re-use it as it was replaced recently.
MUST item to be replaced at every TB/WP service although AT crank pulley has better chance of surviving for much longer period.
As reported earlier, what a mess. This area should be in silver colour…
Interesting thing was that the accumulated debris was not like very wet mixture of eng oil, road film, sand, etc that you normally see on other engines.
It was more like very sticky but not so wet texture, like you will see when you get a/c oil leakage.
I checked the compressor and there was not a single sign of leakage so that was not the case…..
Any way, it’s easier if I remove the TB lower cover before start cleaning the area.
Later, cleaned to this level for the 1st stage cleaning.
Will clean it further once the oil cooler removed as I can’t access the area behind it.
The TB tension was very-very loose…..
It was so loose that it managed to polish the rear TB mid cover and this one is the later spec so it won’t warp like the old spec.
