Good'ol BMW
This is coming out of a BMW 335xi, intake valves. The 335xi is the twin turbo 6cyl. this engine has tons of fuel issues and turbo issues. One of the cars I warn people about owning outside of warranty.
This car is getting a head for other reasons but I need to swap everything over and decided to show you guys some carbon build up that you will probably never see like this.
Car has 98k miles and has always been on time for schedules maintainence.
Exhaust valves are spotless.
I will soak these vavles in a combo of fuel system cleaners over night then take a soft wire brush to them before I lap them for the new head.
BTW this repair is about 12-14k $ out of pocket for a customer. This customer is getting lucky and its being goodwilled
one of the two from cylinder 6 intake valve
This is after a few hours sitting in my concentrate and a light cleaning for those that aren't sure what they shoud look like
Rushed the process, but all clean now
a few other from bank 2 (cylinder 4 5 6)
A combo of carbon scrapped off from the 12 valves before soaking in some fuel rail cleaner and fuel system concoction that I make to clean valves.
Newly added
Good for flow right ?
