I did some research and it seems like it could be the cam chain tensioner gasket on the drivers side. This could be the problem since there is oil residue in the place where the gasket would be leaking. How do I tell if this is the issue or if it is a valve cover gasket issue. Obviously the cam chain tensioner gasket is a lot more work to fix and I would not be able to do this myself.

 

is it wise to also replace the crankcase breather hoses? I understand that when they become clogged or cracked they can cause backpressure issues that will cause seals to leak. ECS tuning has the entire kit and also separate parts. Does it make sense to get the kit or just get the hoses? Thanks
