Ten-year-old champions clean the air intake and oil nozzles by yourself!

September 13, 2024

The old champion, the generation of EA888, has been ups and downs for ten years!
I’m lucky that I’ve caught up with all the problems that should have been on the 888!
Fortunately, Volkswagen has successfully trained me to become a half-repairman!
In the first few years, it was a part of modification and trouble. The enthusiasm was high and there was a lot of trouble. In the following years, it became a part of maintenance!
Carbon deposits are like this in the first and second generations of 888. They cannot be avoided. There is no other good way. It is the most direct to remove and wash!
This time, you must clean the manifold, intake passage, intake valve, fuel injection nozzle, and throttle valve carefully and thoroughly! Replace the inlet port sealing rings, the front and rear sealing rings of the fuel injection nozzle!

Here, I must thank my brother,”One Person 666″ worked so hard for me in the early stage!

Operate the whole process alone for 5 hours!

Prepare some materials and tools!
