Camaro LT5

[srode1]

You brought up the PCV topic in the Hobbs camaro build but I didn't want to ask the question about your system on the LT5 there and corrupt that build conversation, so I'll ask it here. Other than the vent on your oil tank on that build, what did you do if anything to modify the stock PCV system on this engine? And for the oil tank, did you use the air inlet tube as a source of clean air for that side?

Just power read through the entire thread over two days!

Mark - such an awesome build with tremendous attention to detail! You and Matt at Sled Alley have skills and knowledge I can only dream to achieve.

I appreciate the fact that you share so many details and information regarding your builds. I have taken many ideas from this thread alone and hope to apply them to my build. Thank you for sharing it with us.

How many miles have you been able to log on it? Any track time to test all the cooling improvements?

Sorry for the delayed reply. I will say "This is what has worked for me". Not saying it is the only way to go but so far it has worked well.

After a few iterations on dry sump tanks we landed on the system that is on Apex.

A modified Peterson tank that tucks into the cowl of the car, it hold about 10 quarts of oil. I vent out of the valve covers with 2 -8AN lines that tee together to a -10 AN line. That vent line goes to the top of the dry sump tank. There is a little effort inside of the tank to get most of the oil out of the air.

A -10 AN vent line then leaves the dry sump tank to a air oil separator. I like the Mann and Hummel ones. The Mann and Hummel air oil separator has a nice filter in it.

I connect a drain line from the bottom of the air oil separator to return and oil back to the dry sump tank. The drain line has a very low pressure check valve in it. The line need to return to the dry sump tank below the running oil level. The "Clean Air" vent line then connects to the inlet air tub where it is vented to atmosphere, but can suck in clean filtered air. The vent line should go in the air tube after the MAF sensor.

I have done this set up on 3 cars now. If you can keep the oil temp down to about 270F while running on track I have had no issue. Engine bay is clean and dry.

I know it is a bit of messing around, but so far it has worked great with zero oil pressure drop outs and no oil going into the engine.
