This could be old tractor related, so I don't feel bad. I have a
Scag zero turn with a Kohler 7000 series engine. After a whopping
200 hrs the valve cover gaskets started to leak. There is an upgrade
kit, as this is a known issue, that is composite and uses O-rings vs
stamped steel and a gasket. I'm going to try some Permatex Ultra
Black RTV on them as the upgraded versions cost about 100 bucks all
told. I've read where I should tighten the screws loosely just
enough to make the gasket maker start to ooze out, then wait an hour
and torque them down, in this case 44-66 in/lbs. According to
Permatex's site it says to tighten them right down.<br>
<br>
<b>"Apply a continuous and even bead of silicone to one surface,
surrounding all bolt holes. Remove excess with knife at once.
Assemble parts immediately. Do not squeeze out silicone by over
tightening bolts. Re-torque will not be necessary."</b><b><br>
</b><br>
Says nothing about torquing them in the first place, just not to
over tighten, kind of ambiguous. Has anyone used this stuff, and if
so what method did you use? <br>
<br>
Thanks,<br>
