So spark plugs wells were filling with oil so I decided to change valve cover gasket after changing it and running for couple of KMs it started to seeping oil don’t know what went wrong even though I properly and carefully placed valve cover gasket and tightened bolts according to Chris cross pattern.
Also properly cleaned surface of gasket placement.
Can anyone guide me in this regard what to do to prevent it.

Does the gasket come with plug tower rings as well? Locally made gaskets are so inferior that you need to add gasket maker to it for proper sealing.

Yes it does come with plug tower seals. I have tried gasket maker too but didn’t helped much.

Is the gasket an OEM part or after market?

Aftermarket

Sometimes the gasket can just not be of good quality.

Did you ensure the sealing surface was clean and not warped or damaged?

Did you ensure that the valve cover itself is not damaged or cracked?

I've also had the valve cover warp and not seal good. Had to do gaskets on a g35 twice before I noticed a teeny weeny crack. It was a pain in the butt.

I think it is worth the investment in an OEM part, but do inspect your valve cover as mentioned by Affan.
