- Wanting to gain a bit more power by going with a vacuum pump or dry sump setup? Something as simple as your rear main seal could become headache when diagnosing mystery oil leaks or not showing enough vacuum.

There is a full time vacuum evac system on the market that does all the same functions of a belt driven system but designed for the street. The Elite E2-X series. Uses a series of special checkvalves and a special Venturi Vacuum Generator for continued vacuum during acceleration so no crankcase pressure can build. Excellent for turbo or centrifugal SC applications.
thank you for sharing information 🙏🙏🇺🇸🤠🤠
I have a built LSX block that has Gibtec pistons with a very smooth cylinder wall finish. I hooked vacuum to my catch can when I was first trying to set up my PCV set up. With vacuum hooked to my catch can I could feel the power in the seat. It was pulling oil into my catch can so im running it vented to atmosphere now. Might hook up a vacuum or even use the exahust to pull a vac on the PCV system.
I went to a taller valve cover to eliminate the oil consumption. I also went to a check valve on the intake side to stop the reversion in the pcv system.
What vacuum level do you see issues? I run 12-14in on my dry sump ls3 and monitor crankcase pressure. I have not noticed an issue with that as of yet.
The LT seal was toast at 15 inches of vacuum.
The LS seals appear to be a bit more robust.
@@Sdpartscenter thank you very much for the info. ill be picking up a seal for the next winter. For my dry sump road race ls3.
Do you install seals dry or lubricate them? what parts of the seal do you lubricate? also if lubricating the seal what lubricant to you use, engine oil, grease, silicone paste?
They're installed dry, the Teflon beds in on the crank and promotes a better seal.
Why would the Lt pump not work?
