<p>I suspect the reason so many sealants are successful is that it's
not really required. I personally use Gaskacinch on that surface,
used to use it on head gaskets too before I switched to Cometic
head gaskets.</p>

red, High-Tack spray-on sealant with a copper gasket when I
put together my first and last and only TR engine build, which
is now apart for a refresh after 19 race weekends and a total
of 5,500 miles. I sprayed both sides of the gasket, let it
tack up and set them in place. I haven't pulled the liners.
I thought I'd just replace the rings and bearings, check and
polish the crank and refresh the valves and seats and put it
back together.</span> </div>

Marcel has made a good point that it's possible no sealant is
necessary if all conditions are otherwise excellent. The
sealant is just added insurance.</span> </div>

<div> It seems that about all sealants are performing well on
the Fo8 gaskets, maybe because there is no need for it? So,
most products won't do any harm, but be aware of anaerobic
gasket makers : these can cure very fast, forming an elastic
layer of some thou thickness : the Fo8 gaskets won't leak,
but the cylinderhead gasket will. </div>

<div> Folks
<div class="ydp2984ea6cyiv8272376385"> Looking
for some background information and
recommendations on the preferred Fo8 gasket
sealing compound that seems to have worked
for each of you in your various engine
re-builds. And any comments / observations
you choose to share either on or off list.
The motor I am building has a 89 mm piston
and liner kit from BFE along with Corrello
rods / bolts and a Crower dummy main crank
connected at the front with a ATI Super
Damper and at the rear to a Fidanza Alloy
Flywheel with diaphragm clutch, an HVDA
conversion with alloy drive shaft to a
Quaife 4.11:1 diff. and alloy back cover.
Stainless Steel valves with 0.050 oversize
intake thru Mang. Bronze guides. H/S roller
rockers on alloy pedestals. BPNW 270
duration cam. The TR4A head has had 0.040
removed mostly to true things up and remove
prior imperfections. The head chambers have
been mildly worked to smooth any sharp edges
and even things out with a resulting chamber
volume of 60.5cc each. I am planning on
installing Gasket Works 0.022 copper gasket
with their 0.005 “O” compression rings on
the head side of the gasket that will be
sprayed with a copper coating on each side.
Gasket Works sent a set of Fo8 individual
gaskets that has allowed me to obtain a
liner protrusion of 0.0025 to 0.003. Am
aiming at a compression ratio of around 9.75
to 1+/- . Looking forward to as many
responses as possible to assist in trying to
get this critical step as close to right as
I can. </div>
