After looking around the engine bay after noticing smoke from oil that leaked down onto the block towards the driver's side rear (firewall), I've noticed multiple leaks on the driver's side.

There are signs of the cam plug leaking, some valve cover gasket seepage (changed 20k miles ago), some residue on the cam adjuster seals (both sides, but they may have not been cleaned off when changed 20k miles ago), leaking around the oil cap, and where the breather hose goes into the bank on the driver's side.

As far as I know, the passenger side is completely dry except for some residue on the cam adjuster seal.

I recently replaced the suction pump along with the green and blue check valves. None of these seemed clogged at all, but it definitely seems like this could be PCV-related.

I'm wondering what could cause all these seals to fail around the same time. I'd definitely like to get that fixed before having the seals changed just for more to leak.

Any suggestions would be appreciated.
