Guys noticed that the extreme right part of my camshaft is slightly broken. Any ideas what will a replacement cost and how much.

I am also looking at a new throttle body as its leaking.

It's normal for oil to be present in and around the throttle body, just remove and clean it, they get really clogged with rubbish. No need to replace it, New or old they will have same issues

what do you mean broken?take a picture...

TB is impossible to leak,the oil is from the intake,is a bit normal

Thanks guys! Is there any PDF available how to clean the TB?
