Car won't start all of the sudden...

I do have a stock oil cap and the PCV valve and tube are in place. No breather on the valve cover tube yet.

The Ford Racing finned EFI valve covers (the ones that say either Ford Racing, MUSTANG, or COBRA) have a baffle that clears roller rockers fine. I've got a set of finned COBRA valve covers on my Thunderbird and the baffle inside clears the Ford Racing roller rockers I'm running just fine.

I have those, but the baffle was just a flat piece of metal, wide open on the ends and sides.

Do not run a breather with a closed PCV system on an injected car. This is unmetered air and causes idle problems.

New baffle will be fabbed and tested, then, we'll see what happens after that.

Just ordered an NOS Motorcraft PCV valve. Maybe it'll help, maybe not, but it sure can't hurt. LOL. Once the weather allows, I'll do as I stated above, fab the baffle and see what else I can come up with. I didn't drive the car anywhere today, but I did move it up in the driveway. Started right up. Good stuff. Hopefully it'll stay that way. Now to focus on the other issues.

Hmm. Works fine for me. I don't think it sucks much air from the vent tube (I believe it only does under WOT conditions).

One thing to remember is when you increase airflow into the engine (ie better H/C/I) you also increase the airflow through the PCV system.

Im sure you know this but the volume of "air" moving through the valve cover filler neck tube back into the upper intake is directly related to the percent blow-by the engine has and the RPM's. This is also true for the PCV system as it is relieving any pressure on the crank case so we want the engine sealed up as that makes more power and is more efficient.

Thanks guys.

Tome, I had thought of an oil catch system. How is yours set up?

Vinnie, I've been looking some writeups that tmoss did a few years ago, found some relevant info about TFI modules that may benefit you.

More specifically, the so-called push start versions were all gray, and ran till 1992, after that, they were called the CCD style.

Any gray one should work, regardless of the transmission.

Quote
The early TFI system, which Ford calls the "Push Start" TFI system, uses a gray TFI module and were used through the 1991 model year. Originally, the module was mounted on the distributor. In the late '80s, Ford began to relocate it away from the distributor on some vehicles to provide better protection from the effects of engine heat, but system operation remained the same. It uses a Hall effect pickup (stator) in the distributor, which generates a battery voltage, 50% duty cycle square wave, called the PIP signal, to the EEC-IV PCM and the TFI module. The PCM processes this signal and sends out another battery voltage, 50% duty cycle square wave, called the SPOUT signal, to the TFI module. As long as the TFI module is receiving a SPOUT signal, it will fire the coil at the rising edge of that signal (except during engine cranking, when SPOUT is ignored) and the vehicle will run with the amount of timing advance commanded by the computer.

Let me know if you need more info to this particular bit..and I'll copy it all here.

FWIW, I've used a 2,3 TFI in my '88 Sport after the HO swap, and there were no issues whatsoever. I've also used a TFI from a 5.0/AOD Mark 7 on a 1988 Mustang GT and the owner of that car is STILL driving it. I do ALL his mechanic work, so I know it's still the same one I put in 7 years ago.
