Who are you talking to Bariga?

As for capping them, ( I think thats what Bariga is referring to) I could do that, but if they are for equalizing pressure between the heads and the crank case, then it might be a good idea to keep them. HOWEVER if having a catch can on the heads and PCV ventilates enough, then I could see being able to cap them, because there shouldn't be much difference in pressure anyways.

Long ways from that dilemma. Hoping to get my gasket kit this week so I can start bolting things down.

And the 'merely connections', I see your idea but isnt it all equalized inside the engine/heads, or are you just saying for some extra help?

PS - I still think of myself as a dodge diesel person more than an Audi person!

More power means more crank case pressure. I would not suggest capping off vents for the power you are looking for.

What's the point of routing that case pressure through the heads and into a different catch can?

I mean, if you're concerned about case pressure, why not just connect each catch can to a 4-way connector that connects to a crank vent and two head vents? That way you get basically a straight shot from two head vents into two catch cans when case pressure is high.

Parker makes a 90deg PTC (push to connect) fitting with a 320micron filter built in. I think I am going to try it out on my PCV setup. It is made to hold back oil and oil bubbles so it sounds perfect.

just a heads up.

Thanks for help. Going with setup in picture above. I'm trying enough new things on this build. I've already got everything to route and make my catch can setup.

One head is on!

Been cleaning up the sealing surfaces for valve cover and getting oil pan on tonight.

When I was torquing down the head studs, it was the absolute most nervous I've ever been working on a car. ... And no matter how many times I read the instructions... I still missed the friggen bold statement right in the instructions..."If protruding into the waterjacket, use ARP thread sealer"

My dumbass didn't catch it even though Ive seriously read them like 4-5 times since this morning, trying to avoid something like this. Any tips on what to do?

The head studs do not protruded into the water jacket. You didn't forget anything.

the heads are only meant to torque to 90ftlb?
And what are you waiting for or is it just a matter of throwing it all together now?

Depending on what studs you go with and what type of boost you run I've seen people torque the head studs to as much as 110 ft-lbs but for the standard ARP's they recommend 90 ft-lbs.

Well - waiting on getting some camshaft seals for exhaust. Kit came with 4 AVCS sized seals. . . Bummer. Other than that, I might throw on the Intake Manifold tomorrow just to take a sneak peak. Ultimately waiting on money for my transmission right now. I'm struggling not to buy the little things right now so I can get gtasti his money for the trans.

Battery relocation to trunk completed. Thought that it would have to be moved 100% for sure to run reversed IM. Well... Guess it is just easier to remove it now. Might put that Catch can in that location instead.

Interior cleaned up from all the bull**** that has accumulated since September '03. Found a previous owners pocket knife under the carpet

Along with the battery relocation being done, I think that I got the electrical portion of my fuel system complete. Taps into the relay for fuel controller so that it primes then shuts off like oem, though once the AEM is installed this will be gone anyways. Should be all good to throw the carpet in once I get my walbro (another small thing) and set the system up.

Can anyone else comment on the Stud torque? I'm sure that before I get my final tune that I will have the motor out again to fix the inevitable leak out of a seal or something else. This would fit in line with retorquing once heat cycled anyways.

Question time - On the bottom of my heads, there is a location that looks like it is for a cam position sensor or something, but it doesn't protrude into the head, just is a inverted boss so to speak. Only thing that I can think of is maybe that it was for the casting on the V8 heads or V7 WRX heads? I really have no idea. I see there is a cam position sensor on 08+ STi, but Im assuming that is for dual AVCS

Heres a picture.

Yea looks like that. More than likely there was either a model that had both ( I don't know of one, what year are those??? If 07 sti would make sense they were preparing for dual avcs ) or they were just preparing I know my jdm ver8 don't have those , or none that I remember, I only have the larger cam cap on the intake cams exhaust cam is a standard cap

Looks like a awesome build man.

Looks like you have a T in your fuel line, its on the return side so it probably won't be an issue but I've always prefered Ys when ever its possible.

Thanks Sean. They are 07 Heads.

Thanks for the compliment man, hoping it comes together smoothly. As for the fuel line - I can't take credit for building the rest, but I can't take the blame for using a T, as I bought the system. I could look into a Y I suppose. . . The other two merged connections are Ys, so that is good.
