This is my first time removing spark plugs and looking at their quality. What do you think of the quality of these 4 spark plugs?

To me, cylinder 4 and 2 don't look that bad...

Cylinder 4


Cylinder 3



Cylinder 2




Cylinder 1

 

Belongs in the integra forum, look pretty dirty to me. A lot of build up.

 

Moved to the proper forum.

#4 and #2 look oil fouled. #3 and #1 look good, #1 being the best.

Looks like you have an oil consumption problem.

 

Yeah the engine does have an oil consumption problem.

 

How much oil it eating?

 

i didn't calculate it, but i know i have to check the oil level each 2 week.
