Re: engine siezed during intake manifold swap??!?
17 hours is all it's gonna get...
what's the basis behind 24 anyway? why not 23 or 25? I'm guessing it's just because it's evenly the number of hours in a day... it's a clean thing to say to someone.. let it cure for 1 day.. but... I'm thinking 17 should be decent too... i'm sure nobody did a lab experiment that found that 24:00 was the perfect cure time for High Temp RTV...
If I'm wrong, somebody tell me.. but sometimes I think we take a lot of these guidlines a little bit too literally.....

"Silicone fully cures in 24 hours."
If you think you know better than the manufacturer be my guest dude.

Yeah, it sealed fine after 17 hrs. No intake oil leak anymore, no leaks of any kind besides from the coolant bypass tube that i punctured /w a screwdriver and replaced (no more leak from there either, haha).
Engine is running good! Aside from a few stupid mistakes that wasted my time, the intake mani/lifters wasn't really that bad a job, I think I could do it again in < 10 hrs. I'd almost rather do it again than plugs, because it was less stupid agrivation!

Interesting. Have any links that could explain that? Is the oxygen in the moisture that cures it?
In theory then, cranking the engine up while the rtv was not cured could prolong the process.

Here's a quote:
....from this source:
http://yarchive.net/electr/silicone_...osiveness.html
Single part silicone sealers generally contain a cross-linking catalyst (such as a tin compound) that is activated upon exposure to moisture in the air. These single-part sealers should not be expected to cure deeper than about a centimeter as the diffusion of moisture through the cured silicone, and the diffusion of the acetic acid or other compound out of the curing silicone is limited by the thickness. To demonstrate this, leave the cap off a tube of silicone sealer for a few days. The silicone around the neck of the tube will be hard, but the rest of the tube will be uncured.
