<DIV><FONT face="Palatino Linotype" color=#000080 size=4>I'll wait for your
hands-on tests. Assuming you're using stock heads with stock guides, my
guess is that the naked Intake Valve will only drop to the top groove before it
is stopped by the TDC piston-- and certainly no more than have the tip disappear
into the guide by 1/8th-inch. I could live with that... could pull it out
with a decent magnet, especially with the guide all oiled-up and badly
worn.</FONT></DIV>

<DIV><FONT face="Palatino Linotype" color=#000080 size=4>Not to be critical,
Dave, but RTV is a GASKET-<EM>SUBSTITUTE</EM>, not a
gasket-sealer/adhesive. Depending on one's plans for eventual or repeated
disassembly of a gasketed part, he should use something on the spectrum from
Hylomar to "Gorilla Snot" 3M Weatherstrip Adhesive.... Using RTV for a
closed-groove gasket would generate a lot of cure-gas and weaken the contact
points where the original "set" took place as the vapor tried to escape.
I'd <EM>never</EM> use RTV-silicone for that application; besides, the curing
and subsequent re-heating outgases tend to foul, coat, and prematurely disable
oxygen sensors! Just a thought....</FONT></DIV>

<DIV><BR></DIV>>So lemme tell ya what I want... what I really, really want,
what I<BR>really, really, really... [Stop<BR>> it!] wanna know from your
experience or research:<BR><BR>>If I had each respective piston at TDC and
happened to DROP A VALVE (again, no<BR>>pressurized cylinder and assuming
the old valve-stem O-ring had<BR>rotted or tore off so that<BR>>nothing
could stop the valve from falling all the way through a badly<BR>worn guide)
INTO THE >CHAMBER, HOW FAR WOULD THE INTAKE FALL THROUGH<BR>THE
GUIDE? Would the >tip disappear completely into the
valve-guide<BR>before the valve came to rest at the top of >the
piston?<BR><BR>>Ditto... HOW MUCH FARTHER WOULD THE EXHAUST VALVE
DROP? (This is<BR>strictly >theoretical since I'm only planning to
replace the<BR>'guide-boss seals on the intakes and will >likely leave the
exhaust<BR>O-rings alone. They're easy to test for leakage fully
assembled<BR>>anyway... just a few drops of penetrating-oil on the
keepers. And,<BR>remember, I'm in a hurry >on this job! Still,
ya never know....)<BR><BR>>That old VALVE-COVER GASKET THANG....<BR><BR>I
have my motor out my truck and with the heads already removed, later<BR>this
week I will take some picture of the valve cover clips and I will<BR>test out
dropping the valve. I think it will complete disappear, but<BR>I am not
100% sure.<BR><BR>>Why not use sealer or gasket adhesive on the recessed
surfaces of the<BR>covers? When I >spoke of my Trans Am covers and
those recessed orange<BR>gaskets, they were really >permanently installed
and I never had to<BR>worry about 'em "falling out" or even getting
>loose. It was<BR>beautiful-- better than I used to set up my
Fel-Pros or Mitchells on<BR>my old >chrome covers for '60s engines! I
don't get that stuff about<BR>binder clips at all... hope >you're not just
trying to spook me. Know<BR>where I could get a PICTURE of the inside of
>one of these covers?<BR><BR>I actually did try to use some RTV blue, but
it didn't adhere (I<BR>didn't use a ton of it though) Maybe I didn't get
enough of the oil<BR>residue off the inside of the valve cover groove.
My TPI Corvette had<BR>rubber gaskets and they stay perfectly fine in the
valve covers. I<BR>actually tried 3 set of gaskets to see which ones
worked in my Sy's<BR>OEM valve covers. My orignal OEM, the new one I had
used but had 1000<BR>miles on them and a brand new set, they were all to loose
to manuever<BR>through the motion of putting the valve covers
on.<BR></BLOCKQUOTE></BODY></HTML>
