Just pulled my cam tower and replaced the seals on the front and gasket in the back. Now I'm ready to re-install. Should I use any kind of gasket sealer or just put it on dry?

I would coat both sides on that rear cork gasket thats what we do .

I did lightly coat both sides of the small cork gasket on the back end with grease per Clarke's Garage instructions. Now I'm talking about the main gasket under the cam tower. Clarke's Garage doesn't mention whether or not to use anything on that gasket.

I always cote everything gasket\oring like with Molykote Dow Corning Silicone 55 to eliminate any chance for seals to be damaged when installed. This is personal preference and not needed .

I used Hylomar-M, seems to do the trick. I also re torqued the housing after 500 miles or so. I've had the cam housing off 3 times since I've owned the car, the first time I didn't use anything and there was always oil residue on the side of the head where the oil passage is. Second and third time I used Hylomar-M and rechecked the torque, it's been bone dry for two years now.

There's no need to put sealer on the gasket. Let the gasket do the job it's designed to do. Gasket sealant just makes a mess and it's difficult to clean the surfaces next time around.

If there's a gasket in place there's no need for sealant!

If you haven't already, replace the cam tower bolts! Part # 900 067 214 01, you'll need 15 of them.

If they have already been re-used in the past, they are likely stretched from being cranked down against valve spring pressure more than once, and won't provide the necessary clamping force. This is the #1 cause of cam tower gasket leaks (I work on Porsches for a living).

If you don't believe me, read this excellent article on the subject:

Otherwise I agree with with Michael Mount, clean and dry should be OK. Maybe a light coat of Elring Curil T, but no silicone or other messy sealants like so many people use on everything!

Too late - it's already back on. Gasket went on dry. I did not use new cam housing bolts. Pretty sure this is the first time the housing has been off the car.

I guess I could still order new bolts and replace them one at a time.

Hope it doesn't leak.

If that's the case, you might be OK. You should re-torque the bolts after a few heat cycles, however.

Stay safe and stay dry, my parents live in the Woodlands, and you guys have been getting drenched lately, and Houston has been awful! Hopefully you guys get out of that and send some of the rain our way!
