I would think it would be a good idea for performance applications. I'll talk with Tim at LPE tomorrow to see what he says.

One thing.. LPE swaps out the valley pan with a LPE designed Aluminum plate. I have the stock one in my pile of take off parts. Does the LPE valley plate have the hose barb fitting on it? I don't remember seeing it on the LPE plate.

What this is doing is separating and collecting the oil that the stock setup would have pushed back to the intake tract and burnt. The oil will get burnt in the combustion chamber, and dealt with as part of the emissions process.

Is there any benefit from having the oil dumped into the intake tract, I.E.: lubricating the S/C?

Downfall is it will (over time) deposit soot/sludge on the plugs and valves, and eventually clog the catalytic converter. IT will take a very long time to cause the above, but with a boosted engine, I would think it would happen quicker, as the engine will be worked harder. It would be better to not burn it, and collect the oil in my opinion.

High HP applications use a vacuum pump to create negative pressure in the crankcase and route the suction hose to a 1 qt catch can. The droplets are much bigger on a 800 - 1000 HP engine - no baffles required here for oil seperation. the hose has to pass to the vacuum pump, and the output side of the vacuum pump goes to the catch can.

Thanks Guys, I was pretty happy with my truck upgrade.

I had doubts the 1/2 ton was going to be able to pull the enclosed trailer all the way to the C5Fest come April. No problem getting there now!

Does LPE have any experience with tuning VVT cams?

You probably want to call them and ask them directly.

In the S/C'd applications, I believe they eliminate it as it would not be wanted in a performance application.

Okay, will do- the bold part, however, is very entertaining...lol

Speed, Hold off on buying anything until I/we/us check with LPE to see if we need to do this. LPE may have already taken this into account.

Post #1706 (2010badss engine) shows the LPE valley plate. The hose barb is not there that lawdog refers to from the valley pan that he connects to the catch can - it appears LPE has deleted it.
I believe the hose connection at the back is cooling. Here is the Picture.

We should have the one from the valve cover still.. but it will be worthwhile to check with LPE to see if this is worth doing to our cars.

Know what you mean Junkie. I slowed down....actually stopped the booze and bars and other things 22 years ago. For me it was a real good thing never could just do the social thing, figured I was better off leaving it to the professionals.

Thanks for checking on this 570. I wanted to check with them to make sure they didn't account for something like this already. It is the little things they do that makes them the best

Junkie wants to slow down?

Liking your truck 570.

Speed, I know all that snow sucks for driving, but I sure do love it. That's quite a dumping you got there!

With the LPE setup, you would pull from the drivers side valve cover at the rear, and configure the rest as the diagrams show (anyone wants them just PM me your email & I'll send the whole file of most every application forced induction or NA.)

The other issue aside from the obvious excess carbon buildup on the pistons & valves (which affects the burn pattern and reduces the velocity of the intake charge into the cylinder) is that the oil reduces the amount of energy released from each explosion and therefore less power. You want air & fuel in the cylinder before combustion, oil reduces the octaine & the completeness of the explosion.

On our drag cars:


We run alcohol and belt driven vacuum pumps. We keep the vacuum at no more than 14-15 inches (any more will pull oil off the mains & the wrist pins resulting in failure) with an adjustable relief valve in the opposite valve cover that we pull from. This not only evacs all the unburnt fuel & moisture...but the rest of the nasty combustion byproducts from the crankcase.

(a few pics of some of our wins):









We hold championships in both NHRA & IHRA classes at the local, divisonal, National, & World. as well as one of the first to win the NHRA Wally with a C5 corvette.

Anyone with questions on ANY application relating to a proper crankcase ventelation system, just ask & I'll answer all I can.

Oh, and the youngest driver on the team:

Has anyone heard directly from LPE on this yet?

All forced induction is the same....the LPE is a typical roots type blower and will configure the same as any Whipple, Kenne Bell, or Magnuson.

Were dealers for most all and install & do these builds weekly. You need to have a flushing flow through the crankcase & you also need a filtered fresh air source for the make up air.

With a supercharged application, we add inline check valves so when at idle or low/no boost the intake is the vacuum source, but when under boost the checkvalves shut off any chance of reversion or the boost pressurizing the crankcase. Then it is the intake side of the blower that provides the vacuum.

Stay Tuned maybe LPE will post up on this issue soon.
