Should I purchase an aluminum valve cover instead of the plastic one on my I6?

Hi folks,

My Jeep's previous owner did a shoddy replacement of the valve cover gasket, and it's leaking oil. It has the 258. When I replace the gasket, should I replace the valve cover with an aluminum one? Plastic seems like it might be prone to warping/developing new leaks.

Thanks

Yeah get an aluminum one BUT make sure you read the fine print, Some new valve covers like that require you to drill and tap the head... Just a heads up. Its not just a direct bolt on.. I can guarantee The Omix Ada ones require this and some sites like JC Whitney don't tell you that.

My Brother in law drilled into the water jacket too.
