why did this happen?
if any of you know I thought I blew a head gasket last night, I pressurized the cooling system and it didnt leak so its farther in the motor, I pulled the upper intake and the ports looked like this? any ideas as to why?

RE: why did this happen?
Theres about three reasons - and it's somewhat normal to look like that. You have the oil breather tube going from the oil cap spout sucking into the throttle body - so any blowby and oil vapors go right through there, also the PCV valve vacuum gets sucked into the intake - so once again oil vapors and blowby vapors get drawn in there, and one last thng is exhaust vapors sucked in through the EGR go throuhg there. The mixture of all of these makes the intake runners look sortof like that.
If the motor is tired, it will look a bit worse as compared to a good running one.

This one is mine... engine runs ****... super clean on the inside, but a bit dirty on the outside... you can still see the factory paint that they use to distinguish between intake and exhaust valves...
But the intake runners are a bit messy never the less.
