: Looks like time for a catch can

08-03-12, 01:00 PM
I opened the intake to see what I find since my car has never had a catch can. The initial view in photos was enough to tell me I need one.


Also got the scope down to the valves. It doesn't have the best view, but it's enough to see I need to address the carbon buildup.


This is with just over 30,000 miles of someone else s driving. Gotta clean up my ride! ;)

Tough to see the valves, but it was carbonized.

Yea, the scope has 4 small LED lights, but they're not the brightest, especially when everything down there is covered in black soot and carbon. Next time I have the top off, I plan on shining an external light source in there to see better. Just kicking myself for not thinking of doing that the first time.
