Using Toyota Form-In-Place Gasket Maker on Timing Cover--Set Time??

I just put the timing cover back on my truck and I'm a bit worried about the gasket maker I used (Toyota part #

$21 00295-00103 Formed-in-Place Oil Pan Gasket - 3 oz. Tube

00295-00103). The FSM says that that if you don't get the cover on in 3 minutes to scrape it off and reapply. Then, you have 15 minutes to get the water pump on, or you have to pull the timing cover and reapply the sealant. This is for an older version of the sealant, but supposedly the set time is still 5 minutes for the one I used.

I had trouble aligning the oil pump and finding the water pump bolts. It probably took closer to 8-10 minutes to get the cover on and 20 to get the water pump on. Should I be worried? It looks OK from the outside of the engine, but when I realized that coolant could potentially leak onto the timing chain and into the oil I started getting a little nervous.

Is it really as big of a deal as the FSM makes it sound? Should I pull off the cover again and reapply the sealant?

 

Whelp, I used a valve stem and an old radiator cap to pressure test the system. It held 15psi for half an hour, so I'm going to call it good.
