Troubleshoot it starting with the cheapest “fix” first. I would change the oil you use first. Get away from Mobil 1 and use a heavier weight. You don’t drive it in the winter or below 32 degrees so you could def, get away with a 20-50. 10-30 is even better than what your using now. That should help, if not, catch can. ---

5w30 is not too light IMO. I wouldn’t go any heavier than 10w30… see if you can find something like this: [http://jlttruecoldair.com/zencart/index.php?main\_page=product\_info&products\_id=23](http://jlttruecoldair.com/zencart/index.php?main_page=product_info&products_id=23) 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. ---

All my old shit i run thick oil in too, but the new shit it’s really not required and will cause excess friction and loss of the all important HPs! yea I suppose… On another note Try 5w40… not sure how much differant it is from 5w30 but Im running amsoil 5w40 in the z and seems to burn way less oil than it did with 5w30 ---

thats some heavy oil for a cold start. 20w50 would be better in africa, not here… use a quality 10w30 or 5w40. i use castrol, but amsoil is awesome. ---

the 10 is the cold weight. 30 is the hot vicosity rating. if you run high oil temps a 40 would be better… id say a 10/40 or a 5w40, like the Rotella T ---

I have the Ported LS6 oil pump because its cheap, safe insurance on my new motor. I spin to 7k now with Patriot performance gold dual valve springs(.660 lift), texas-speed chromoly hardened pushrods (7.425) and a big cam so the more oil pressure I can get to the top end, the better off I am in the short and long run… not to mention when the cam swap goes under way, the oil pump is right there anyways so why not have it changed? It was installed with no extra cost. I did alot of research on my setup before I went with what I got, and I have the oil pump because its highly recommended for my setup on ls1tech. ---
