thanks.

I think I paid 30 for my gasket. 40 is not that overpriced once you factor in shipping and whatever profit margin your shop has to make.

+1

Spark plug tube seals need to be replaced and only come with new valve covers. I know Toyota sells these seals separately for their v6 engines.. would be interesting to see if we can substitute their spark plug tube seals in place of ours...

I know their differential and trans aluminum washers are a direct replacement for the ones that Nissan sells AND they're less than half the price

My leak wasn't as bad as I thought it was, I had the valve cover gaskets replaced and the tube seals sealed up with silicone. The coilpacks were cleaned and reused no problem.

So far so good.

Im thinking u might be able to reseal the plug gaskets if u can get creative with 3m 5200 sealant. That **** is super badass marine sealant. Just a thought.
