Some technical supercharger questions
Some technical supercharger questions Wondering if you have too much crankcase pressure and it's causing oil to come out of dipstick tube or other vented areas (breathers) what can you do?
I've heard of running a crankcase evac system and that you can run them to your headers or to the suck side of your supercharger but I don't quite understand how it sucks pressure from the bottom of the engine when it's being sucked from the top (valve covers)?
Also do rings take time to seat?

Weekends sometimes take a little longer to get a reply.
I ran more breather lines to catch cans when I upgraded to the T-trim and really started making over 10#. I have a -8 line to the front of my oil pan, on each valve cover I have a K&N breather and a -6 line to a catch can.
I don't like using a blower 'suck' vent with an intercooler, because IMHO it gets the inside of the IC dirty with oily residue too quickly and cuts down its efficiency.
Rings do take time to seat. What kind do you have?

I haven't gotten the car yet...tomorrow but I know the 2nd rind is gapless from my understanding.

What is your point about the gapless ring? It doens't mean anything. And I don't care if it is an LT1 or and LS1 if you have enough crank case presure to push the dipstic out then you are having way too much air go by the pistons some how be it through it or around it period. And asking someone to diagnose something not in person is not the best way to figure it out as we are all shooting in the dark. If the compression test was good what are you saying is good they are all with in what percentage??? Do a leak down it will tell you more.

I have pix but mine's a 383SBC in a 81 Malibu... Since you have an LT the solutions I used might apply more than they do to a LSx motor.

Thanks for the replies.
On mine the dipstick tube isn't flying off or anything like that, rather under throttle it's leaking out oil from the crack of the dipstick tube and dipstick.
Mike, where would you run a set up like that on a supercharged (vortech t trim) application?
Thanks

It wasn't pushing the dipstick out unless the pistons were broke. However, I had a hellacious oil leak that I eventually figured out was coming from around the dipstick tube where it inserts into the block. That totally went away when I added a 2nd vent.
sworaz, the stock Vortech setup should run a single vent from the PS valve cover to the plastic SC inlet pipe. You'd simply replicate that on the DS valve cover. Drill and tap another hole in the SC inlet pipe.
