I'm trying to set up a pcv and breather system for my maf operated TPi system. Any thought or suggestions? In the diagram below, i was going to route the pcvline to the underside of the top of the stealth ram where there is a hole tapped for i think 1 1/2" fitting. The breather line I was going to run to the throttle body. Doesn't one of those fitting produce air and not vacuum?

Billest Specialties Breather #BSP-20120
Diameter (in): 2.491
Height (in): 2.500
Valve Cover Breather Attachment: Push-in
Notes: Designed to fit 1.250 in. valve cover opening.

Summit PCV Valve #SUM-440308
PCV Angle: 90 degree
Inlet Attachment: Hose barb
Inlet Size: 3/8 in.
Grommet Included: Yes
1.22 in. O.D

Please give me your thoughts/changes!

I dont quite understand why your still asking about this? did I miss something?

The top line on the TB will be the on for the breather. The second one down should be for the CCP if your car is still so equipped.(double check this I am going from memory, vader and i have both posted the correct ones if u search.)

I would rather see u install a stock type delco pcv valve. On the breather side, u could use the breather or just a line like originally came from the factory.

Either way u should have a pcv setup on any street type car, helps out with crankcase pollution and doesnt let the pressure build up in the actual engine itself.

Alright, I got it. It has been so long since started this swap that I forgot how the vacuum lines were routed. I needed the memory refreshment. I'll go to NAPA tomorrow and pick up some grommets, vacuum hoses, and a pcv valve. Thanks again Jeremy.

In case anybody is doing a search and needed this information.
Top Port = Air
Lower Port = Vacuum

When in doubt, get it as close as u can to the factory way.

U gonna do your own prom tuning on that thing?

I already started. I'm using the "APYP" bin for the `165 which is used for the `89 5spd TPI corvette. The timing tables is the big part that differs. Basically, all I really did now was take out the emissions, vats, and othermisc. things. When I get back to college for next semester, I'm going to tryto use the dyno there instead of emulating myself. If all goes well, it should start tonight or tomorrow.
