I'm not good at forums, but need help. Had Cam shaft seal replaced recently, now I'm told the valve gasket cover is leaking. It was replaced 6 yrs ago, 2013, and we put on around 10K a year. Didn't expect to need to redo again this soon. Might they have messed it up when doing the Cam Shaft seal job?

Maybe the bolts just need to be tightened slightly.

Who replaced the cam seals? The valve cover bolts are somewhat delicate with a very low torque setting. It's very common for them to come loose OR get over torqued, causing damage to the washer, both of which can cause leaks.

If you are keeping the car do it and be done with it!
