Caution, GRAPHIC NSFW PHOTOS!
This is on an engine with 48,000 miles, after a 9,000 mile rebuild. I'm not sure if the tech cleaned it during the rebuild. I run Mobil 1 synthetic, K&N filters, and my only real performance mod before this dis-assembly was my vararam.
Significant puddles of oil on both sides! NOT good!
Throttle body plate had significant build up
Lots of oil on each runner...
Real glad I bought an entirely new manifold + catch can. You don't need to be a mechanic to see how bad this is. I can't imagine what 100,000 miles would look like!
