Another cam plug leak question.
Hi guys so I dropped my oil pan to redo the gasket since it was leaking. It’s sitting overnight now letting the rtv cure before I put oil in it. I looked at the cam covers that I read were also prone to leaking while I was down there and noticed they are also having little leaks. My question is. To replace the gaskets for those does the oil need to be drained? I have new Mobil 1 to put in in the morning. But don’t want to fill it if I’m gonna have to drain it to fix the cam plugs, I’d rather just keep the car in the garage until I get the parts

The spots I found leaks are the two bigger covers on each side. As circled in the pic. Does anyone know the actual name or have a part number for new gaskets by any chance?

I found a replacement kit for all the parts. Except the big cover on the left of the picture. Is the bigger plug in this kit inside the cover by any chance?

The big one on left side with rectangle sticker is vacuum pump.

I assume you found the answer (if you've found the kit) but just in case...
The cam plugs do not have gaskets... You replace the actual cam plug itself...
As for the vacuum pump, that does have an o-ring to prevent any leaks.
Lastly, no need to drain the oil to replace any of the above.

Perfect guys thanks. I was able to find a rebuild kit or the vacuum pump (it’s just the putter plate leaking from what I can tell so I should only have to pull the end cover off and not the whole pump) and MB oil separator from amazon. Plugs aren’t leaking yet but will keep my eye on them. Finally stop smelling burning oil haha. Like I said finished the oil pan seal today can’t wait to fix the last of the leaks.
