James and I redid the wires on the T/A yesterday. Got the Accel universal wire set, crimping tool, and two sets of Taylor looms. I think it looks much better and I don't have to worry about burning wires on my headers! Wink
I think I will get some brackets that attach to the center bolts on the covers to clean it up a bit.

And it only took you like three years to finally do it! LMAO

On my old center-bolt engine put little L-brackets on the valve cover bolts and then ran an M8 bolt with a nylocker through one hole of the three-slot Taylor clamps. I ran the front pair of wires through the remaining two holes. This also supports the rear pair as it, combined with the four-slot, holds them up.

Also, while I'm looking at pictures of your engine, what are you doing with the crank breather on there? I can see your PCV valve on the other side! Pokey pokey

You gotta let air in somehow. As long as its not a MAF setup the breather works fine. Of course.. is that a maf i see? If so thats a major tuning issue.

Look just above the shiny Chinese filter, B. Cool

The beauty part is that you can see the capped-off bypass line just inches away on the throttlebody. Laughing

Ok John you need to ditch that crankcase filter and get it hooked back into the air intake tract behind the maf. The filter is allowing air to enter the injection without being metered by the maf. Throwing the tune all out of shape.

I've been teasing John about that for awhile now, and I'm reminded every time I see that car.

It's one of those John things that may get fixed eventually (like the burned plug wires) or maybe the apocalypse will happen first, and he won't have to mess with it! Laughing

Yeah, was trying to remember how you had described your setup to me. I got some extra 3 hole looms so I'll give that a try.

As for the breather, I just haven't gotten around to running a hose up to the TB. I also need to get vacuum hose for the PCV valve as it pinches closed under vacuum and makes a horrible squealing noise (some of what I thought was belt squeal).

I almost bet the reason it runs well at all is that the hose is pinching shut! One problem almost cancelling another.

I did not know the breather allow air into the intake! How? It is capped at the TB.

Through the pcv! The pcv system is designed to suck air from the air intake through one head, out the other head, through the pcv valve and into the intake. That's why the breather port is between the maf and the throttle body, so the pcv air gets measured before actually entering the intake.

Yup yup With the setup you have now the air being drawn through the crankcase is not seen by the ECM, so it does not add fuel to account for it. That will cause an overall lean condition.

If you want to see it in action take the oil cap off while the car is running. The idle will dip and the car will start to run rough.

Yup! Want to get a few more things done before then. Might try to do a little more tuning, but tuning in $6E isn't very intuitive.

Since the breather and the pinched off PCV hose are essentially cancelling each other out, I have no mechanical issues. Very Happy I am more trying to get into tuning theory right now as I have only done minor changes to my prom so far and am still learning. Wink

I did the wire bracket how Aaron described to me. It worked out really well! And it was cheap! Wink

Would still clean things up to run the fresh air line to the TB the way it is supposed to be done.
