5w30 is not too light IMO. I wouldn’t go any heavier than 10w30… see if you can find something like this:

that should keep the oil out of your PCV system. It’s a problem on the boosted cobras too. I know when I took my intake off to swap over the K&N there was oil in the TB. Dunno if they have em for Chevy’s but if they’re the same size it’ll work.

5w30 seems like water in high temps… I mean granted its fine but i dunno I’d rather use a heavier oil and not have to worry about it breaking down and burning off really fast
