A couple advisories about using RTV that I have picked up over the years.=
=C2=A0=20
Not all RTV sealants are the same.=C2=A0 Some are oil resistant and others =
are not.=C2=A0 "Automotive" RTV may not be oil resistant and are intended f=
or sealing windshields and such.=C2=A0 Check the manufacturer's website.=C2=
=A0 Ultra Black, I believe, is oil resistant.=C2=A0 None, as far as I know,=
are gasoline resistant.
When=C2=A0 using RTV sealants, apply an even bead and assemble the parts lo=
osely and let the sealant partially set before tightening.=C2=A0 This will =
reduce the tendency for the sealant to ooze out strings and dingleberries w=
hich can clog the oil passages in the engine causing all manner of expensiv=
e problems.
When using RTV in the absence of a gasket lay a piece of thread or string a=
long the joint to prevent metal-to-metal contact ensuring that there is a l=
ayer of sealant at all points along the joint.
As for me, I prefer to use Formagasket #2 on one side to stick the gasket (=
more or less) permanently to one part and Hylomar non hardening to allow fo=
r easy removal/resintallation.=C2=A0 Until Joe Alexander produces a silicon=
e sump gasket I will continue to do so.=C2=A0 ;-)
