[Syty] Valve-Cover Gaskets...?

[DOlivares]

Haste makes WASTE!

That's why I'm trying to get as much homework done now... before I start in with wrenches & stuff.  Next time, as a veteran, I'll be able to do it in my sleep!

    Not to be critical, Dave, but RTV is a GASKET-SUBSTITUTE, 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 never 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....

  I know it wasn't the right application, I had used only dabs in 6 places.  The RTV didn't stick to the metal valve covers anyways, and I didn't reuse those gaskets. 

  It was a time of desperation, I had already slice two of my fingers trying to put the valve cover while trying to hold the gasket in place & it hot as hell, with sweat dripping in my eyes.  The valve covers had been leaking, I was doing this at night in my garage and I was getting ready to make a 500 mile each way trip to a meet the next day, so I had to start trying something, I ned the valve cover on that night.  On the trip, one of the covers still leaked and I ended up redoing it and using those binding clips.
