I am about to install a new Opti and wondered if you guys have any suggestions to make it more waterproof.
I have a '94Z converted to the '95 vented Opti, I don't want to open it and let all the Magic out, but I wondered if the factory seals were adequate, or should I try and seal the Opti some how (Silicone). What if anything do other people do?
In all the optis I have replaced and helped to replace, we have never gone in and added any seals or sealant to add in the waterproof area. I think the factory stuff is good enough.
One thing... Make sure you grease the opti seal on the front timing cover before putting the new opti into place. W/o that you run the possibility of ripping that seal and causing an oil leak. Chris can tell you how much that one sucks!!!
