I, too, learned the hard way that it's better to risk a little oil weepage and use most of the 308 camcover gasket dry if you can (or maybe only use dressing on the camcover side which is easier to scrape). Of course, if you've got a known trouble spot in the flat areas, using a little dressing there on the cyl. head side wouldn't be a sin IMO.
Found this on the Loctite website for one of their RTV products:

that indicates you might want to wait at least 6~12 hours to get a fairly robust (.5 ~ 1 mm) skin on the thicker sections. If you're also using RTV on the lip seal ODs, I'd at least let it cure overnight to minimize the risk of spin-out -- JMOs. |

Hi all,
Does anyone have any recommendations on how long to allow the RTV stuff (Three Bond 1211 in particular) to cure? I plan to finish up my cam belt job this evening and will be dying to fire it right up as soon as I finish torquing the valve covers.
How long should I wait?
In the past I've been putting the RTV only at the points where the gasket meets o-rings and at the other end of the cams where they meet distributor bases and cam end caps (this is a 308QV btw). Does anyone "highly" recommend also coating the gasket? I've never had a problem NOT coating the gasket, and it sure makes prep of the surface easier NEXT time around if there is nothing on those gaskets....
Thanks,
-matt |
