Oil leak, rear lower intake.

You better not "vent" the valve cover to vacuum, As in behind the throttle body on the intake side, unless its the pcv system. The crankcase needs the pcv hooked to vacuum and a port to breathe through.

It's a pcv system and from the factory they have a hose from the oil fill to the throttle body. I'm not sure if its before or after the blade.

I didn't add this feature back with the new set up, figured I wouldn't need it.

Side note. Ran a 01 cobra from a 70roll and tore his ass up lol

Something makes me think that would smooth out my idle.

Sometimes it's fine and sometimes if I've been driving a while and go to idle, it shows 17-18:afr and gets really rough and hunts for an idle. As soon as you tip in it goes back to 14:1, and fine otherwise. I was thinking maybe a slight miss or something? Maybe tune related?

I set the idle through using the tsb method, idles good.. Most of the time.


I just want everything working 100% before I have someone tune it. No sense in tuning a turd.

I was thinking of putting a hose barb on the upper intake behind the the tb, there is a plug there now, run it from the oil fill to that.

That should work, right?

Yes .

[Diabolic]

Yep.

You have the Accufab Race tb that does not have the tube on top. You will have to tap into the intake tube.

You can run a hose from the VC to the tb or to the intake tube after the MAF meter. This will vent the crankcase at wot.

I remember reading this a while back. I'll have to put it back on.

I just used orange silicone on my Capri and no leaks.

I use guide studs to set the intake down also. Leaves no room for you to "wiggle" the ends and fuck up your seals.

Not much of a contribution on my part but this always works very well for me.

Use Ultra Black...... if you're not already using it, not just a black silicone. Like mentioned above, let it get tacky before putting the intake on, give it 10-15 minutes to cure after applying then lower intake down. You should be able to lightly touch the surface without it being wet, it will have a light skin to it when ready. I rarely use gaskets between the block and intake on any of the v motors. Also, if you have excessive blow by, it will push out and leak from somewhere, it's just a given. The down side to not having a fresh tight bottom end when you install a nice tight top end is the potential for heavy blow by. A leak down test would help to diagnose this.

What he says. Toss the end gaskets. Use the Ultra Black in the pressure can. I use one wide bead then another thin bead on top with build up in the corners on both sides of the intake gaskets. Let it sit long enough to get a light skin. I use guide studs to set the intake down also. Leaves no room for you to "wiggle" the ends and fuck up your seals.

How long after you dropped the manifold did you start the engine? If you didn't let the RTV cure you just blew it out anyway.

Maybe lower intake to head fitment? What Brodix head?
