Hey don’t feel bad about $150...some of us have spent way more than that. Money wasn’t really a consideration in my case. :head3:

I was going to mention earlier...I wish my money manager (my lovely wife) would allow such purchases as a supercharger. :drool:

And I just noticed you wrapped your intake with exhaust wrap. Great idea!

This is good to know. Since Covid hit I’ve been working from home and the only use my ‘07 is seeing nowadays is the trip to the community mailbox down the block.

Yup. The temperature swing from the engine cooling after a drive produces condensation inside the engine in addition to the moisture created as a byproduct of combustion. Short drives produce moisture but aren't long enough to burn it off, so it collects in the oil in the pan. When the engine does get hot, the oily water is the first to steam off in the PCV system so it fills the catch can. In the meantime, you're pumping oil polluted and thinned by water through your engine.

Depends on what is causing the oil consumption. If it's not severely worn rings and it's the usual rocker cover design and AFM, then a catch can will help. Getting the updated rocker cover will help even more. Disabling AFM or adding the deflector to the relief valve in the oil pan would help even further. All options combined should just about eliminate oil consumption issues.

The updated rocker cover keeps the oil in the engine, which makes it the better option out of the three. But, with how cheap a catch can is, there's no reason to not get one even if you have the updated cover since the PCV system will still pass oil. IMO, I'd disable AFM before dropping the pan to install that shield. Having it disabled can be done for a little as ~$65. The labor involved in removing and replacing the oil pan, plus the ~$50 gasket makes that $65 a bargain!
Hi @iamdub
Is this something I should do for my 97 5.7 vortec?
