did you overfill your engine with oil?
Anyway, yes your hoses do need to be replaced. That they are clogged up is....well i tell you what, can you shoot us a video? Sometimes its difficult to follow when you take close up shots without a zoomed out version showing us the bigger picture of the engine bay area. We are not experts at this as yet so the zoom out to zoom in view helps alot in understanding things. The video would be best. It can be easily done by any standard camera that you take shots with. Select the low res setting for the video feed and proceed.
