Yeah I’ve had problems with this and have made sure.

I will do this as precautionary but replacing the coils have seemed to have solved the problem.

However, given how easily it is to change that sensor seal, you can first clean off the oil with electronic parts cleaner, and replace the sensor seal. See if the problem returns.

So I’ve replaced the valve cover entirely because I believed it to be cracked near the valvetronic motor. But after installing the new valve cover there was still oil in the same area. And it turned out to be the valvetronic motor gasket the whole time. and I fixed it with RTV and hasent leaked since. It didn’t end up being cracked but oh well. The previous valve cover has as new ESS seal in it so I’m probably gonna rob that and install it in the new one. But I’m just worried about the oil pooling in the connecter leading to failure.
