calling all split porters

i did the split port on my 94xr7, so far so good. however i noticed that i have oil dripping from the inside of the throttle body, im curious if i did my PCV set up right. could someone take some up close pictures of the PCV routing on there splitport set ups.


Also for those that did this swap, do you guys have a howl coming from your cone airfilters, i got a 73mm maf, and the stock stang TB, no air box though... any thoughts on this.? it sounds incredibly loud, i can hear the suck action over my dual exhaust,,,... kind of embarassing!


thanks for all your help guys

Conical air filters do tend to make a fair amount of noise, especially if you don't have a cold air box or divider of some sort. The one on my Splitport 94 LX is a little noisey, but the one on the XR7 is noticeably louder.

rod could you take another picture for me, underneath your throttlebody catching the valvecover. because on my BBK's i have a hose that attaches to the valve cover going behind the TB. is that right?

and where does that hose you have go to? the black hose on your intake pipe?

The black hose going into the intake tube is the PCV hose, which comes off the PCV at the grommet in the valve cover (which is what I believe you're talking about above).

Not really, but I don't even remember the last time I popped the hood on that car. It sounds like it's a vacuum line. If I get a chance, I'll take a look on mine.

There were big probs with the 99+ valve covers sucking oil threw the PCV.

My buddies car when we did the swap (mustang intake) the howl was horrible sounded like a pipe organ while running.

I now have a 4.2L and running the windstar intake setup and it has no howling noise.

Here is another.

Note that placing the MAF that close to the TB doesn't work. It needs to be reworked.

We never could fix the howling,, it was something to do with the mustang intake and the IAC

214/200???? cam is that right? most cams have more EX durataion then INTAKE.

Also do you remember the LSA and Intake centerline angles?

Hows the idle?

4.3Lcougar, I took a look at the line you're referring to tonight. It is a vacuum line, which needs to be routed to the main vacuum tee on the firewall behind the upper intake.

Here are some pictures. Excuse the dirtiness, daily driver duty (500 miles a week) takes its toll.

In this picture, I've highlighted the line that I believe you're referring to in yellow (it's a vacuum line).



I've circled the vacuum tee in this picture:



Here is an overview of the passenger side of the engine:



And here is one of the PCV on the driverside:

Jim, I think the bigger problem there is that you have the MAF mounted backwards. Though you're right, ideally you don't want to have the MAF that close to the throttle body.

I just got home from work (super long day) so I'm not going to be able to get a picture tonight, but I know which vacuum port you're referring to, and I also know that I just have that port capped off.

well the intake is the 214/220 and the exhaust is the 512/512. the idle is pretty lopy, but thats how i wanted it. wanted to sound like a muscle car ( and it does) throttle response is really really good, like with the SC when you floor it and get thrown back in the seat. but thats also because of the transmission i have and the gear ratio.

I think you mean that the intake/exhaust duration is 214/220 (which doesn't sound right), and the lift is 512/512.

Scorpion Rockers ehhh.. Curious if you just bought a set that fits a 302 ford? or are they for a 351C?

I'm trying to locate a rocker with the exact same geometry of the stock 1.73 Rocker.


Actually, 214/220 does sound right,, any ford and especially the splitports need alot of duration on the exhaust side.

The single ports required less because the ports were bigger.

i actually bought the rockers from supercoupeperformance, and they also carry them at SSM. the reason i had to do that cam spec is because of the 351W long rods i used in the stroker kit.

you wouldnt by chance know the part number stamped on the rockers? or did they come in a box with a part number? I'm trying to figure out what vehicle they were originally designed for as nobody makes a rocker specifically designed for the 3.8L/4.2L engines.
