Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

Very clean exhaust/CAT area. Should be easy to disconnect the spring loaded bolt/nut.




Interesting way of preventing CEL at the secondary O2 sensor.

I know several owners tried extended tube method but you don't see so often using this angled method.
Seems to be working well for this setup as there was no history of CEL when reading through the OBD2 scanner.
Will look at the O2 sensor voltage output after cleaning the TH body as it should stay very stable.




Fairly dirty eng bay so hope I can do better job in cleaning it.




Another engine with FR/RR IG coil cover installed at wrong orientation. The rubber gasket was at the bottom side doing nothing and allowing water to enter the IG coil area.






Also, on this engine, two metal collars/spacers were missing resulting in damages to one of the IG coil cover. The cap nut can't hold the IG coil cover down. Someone must have known it as I saw another nut used instead of the spacer to prevent further damages to the other bank coil cover.

Thought about repairing the damaged cover but considering the fairly cheap price, not cost effectivne so agreed with the owner to order new one. I just hope it's in stock as last time, the front one was on back order. I need the rear one this time but can swap the rubber gasket and use front one insead if the front side is available and rear one out of stock.




Will carry out the compression check followed by preparation for the engine removal.

More to follow later.
