I had already posted about a month and a half ago about taking off the valve cover to adjust the settings and discovering large chunks of buildup on all the internals. Since the problem Ive changed the oil 3 times using engine flush each time and running it once with a qt. of marvel in the crankcase. Still the last time I changed it there is still obviously alotta crap built up inside. Im just curious as to how many of the internals are also clogged up with crap robbing me of horse power? Kinda skeptic on taking my car to a Honda dealership want to get it taken care of right but no one seems to have much experience on this situation.. Thanks in advance for any help....

 

describe this gunk
you are aware that oil runs through the head right? Seeing oil in the cylinder head is not a bad thing...just making sure we are on the same page.
So again describe this gunk.
