I just found I had to have my userid and password entered to view that link and assuming the same's true for anyone else, here's the "meat" of the article -
| Federal Mogul wrote: | Fel-Pro Introduces Solution to Intake Manifold Gasket Leaks on Millions of Vehicles
SOUTHFIELD, Mich., Oct 14, 2004
Available through Fel-Pro suppliers across North America, the brand's latest
gasket innovation ensures a lasting seal on millions of domestic engines that
rely on extended-life coolant and were factory-equipped with rigid nylon and
molded rubber-type intake manifold gaskets. A broad range of domestic engines
may be susceptible to these sealing issues. Immediate coverage of the new
Fel-Pro solution is offered for General Motors 5.0L and 5.7L engines
manufactured from 1996 through 2002. Additional coverage -- for select Ford
(3.8L, 4.0L and 4.2L) and G.M. (3.1L, 3.4L and 4.3L) applications -- will be
introduced in early 2005.
"It appears that on some engines, the use of conventional plastic-and-rubber
gaskets in combination with the more aggressive 'OAT' (Organic Acid Technology)
engine coolants has caused a significant number of sealing-related issues for
consumers and automotive service providers," said Fel-Pro Chief Engineer Jerry
Rosenquist. "Our team has spent the past two years developing and testing a
variety of gasket technologies that can survive in this very difficult operating
environment.
"Our new PermaDryPlus gasket is absolutely the best answer for millions of
engines exhibiting sealing problems induced by aggressive coolant chemistries
and engine-specific dynamic issues."
The new Fel-Pro PermaDryPlus gasket features a high-strength aluminized steel
carrier that is edge molded and encapsulated with a proprietary fluoroelastomer
(FKM) material. In addition, the new gasket features three separate sealing
beads around coolant ports to ensure a long-lasting seal under any situation.
A key element of the Fel-Pro design, the new FKM material was specifically
formulated by Federal-Mogul chemists to resist OAT coolants. "We ran our final
dyno test for 612 hours and the gasket looked so good it was difficult to
distinguish it from an untested part," Rosenquist said.
"The steel provides the strength needed to resist cracking and crushing, and the
FKM provides exceptional fluid sealing under all conditions. This design solves
the primary leakage issue everyone knows about as well as other concerns typical
of engines that have entered the repair cycle.
"The consumer and service provider recognize the problem by the coolant spots
that are left on the ground. Unfortunately, retorquing the manifold bolts simply
causes additional damage to the carrier, making the leakage much worse,"
Rosenquist added. Coolant ultimately can leak into the engine oil, causing
significant damage to internal components, he said.
Fel-Pro engineers tested several gasket technologies before identifying the new
encapsulated design as the best solution, according to Rosenquist. "Our ultimate
design is the right choice by any measure - strength, fluid sealability,
corrosion resistance, affordability, and ease of installation."
The new PermaDryPlus gasket was subjected to thousands of hours of dynamometer
testing before being approved for production. Among the tests was a deep thermal
cycle evaluation in which the engine was heated to 240 degrees F, then "shocked"
with 0 degrees F coolant in an attempt to induce gasket failure.
"This gasket came through with flying colors - it's absolutely awesome,"
Rosenquist said.
Other key design features of the new Fel-Pro PermaDryPlus design are stainless
steel load limiters and integral locator pins molded into the FKM material.
This new technology is now available as part of a complete Fel-Pro Manifold
Installation Set (Fel-Pro P/N MS 98000T) for G.M. 5.0L and 5.7L V8 truck engines
manufactured from 1996 through 2002. This time-saving new set contains all of
the premium technologies needed to complete an intake manifold gasket repair,
including PermaDryPlus lower manifold gaskets, upper manifold gaskets and an
advanced PermaDry(R) valve cover gasket.

problem-solving designs, contact your Fel-Pro supplier, visit

Very interesting.I just bought a 1994 Ford Ranger with a 4 liter engine.The lady that owned it before me has a pile of reciepts for work done over the last 3 years and i've noticed on the invoices they've stated that they have removed and cleaned the intake and throttle body twice in three years.Could that be why?

Seems like a, as they say, "definite possibility". 'twould depend on what type of antifreeze was used.
I have no idea when Ford started using the new "OAT" stuff.
