I have a 13 year old Bryant 350MAV gas furnace. The 2 halfs of the inducer housing are leaking water. Can these 2 half be pulled apart and resealed? If so what special type of silicone needs to be used if any?

Can be done. Remove the screws around the edge and work your way around the latch tabs until you have separated the halves. Clean out the old sealant as much as possible and use a good quality high-temperature sealant like RTV-162. Allow a couple hours for curing before putting the system back into operation. Make sure you use some of the same sealant on the tri-oval opening behind the inducer.

Do I need to pull the entire inducer housing off or can I just split the halfs while the inducer housing is still bolted to the collector box? Also do I really need to use Pam cooking spray as a releasing agent as the maintenance book says between the inducer housing and the collector box?

If you think you can do this without removing the whole assembly, then go ahead. If you encounter difficulty you can always take the other half off. PAM optional.

Thank you very much for the help. I will attempt this when we have a few warm days.

Do it very soon, if it leaks that nasty liquid onto the heater box or anything metal, it will rust it quickly and badly. We had dealer replace our heater box ($400ish) because it rusted a hole right through. Would hear a loud whoomp! When it ignited. I sealed the plastic inducer hsing with blue automotive rtv (another possibility is RTV162 mentioned above) and then built a plastic drip tray from a tupperware lid directly under the inducer housing with a tube draining into the crawlspace. 2 years and so far so good.

That system has a recall on the heat exchanger you may get lucky and get the work done for free with a new heat exchanger. Get model and serial number and call 1-866-517-2490. Good luck.
