Front cover RTV questions
I was considering installing the front cover on my 20b with no gasket in order to get more crush on the front iron -> front cover o-rings.
I found this thread:
https://www.rx7club.com/3rd-generati...et-rtv-940406/
which described many reasons not to do it, however I don't need to retain a working OMP. Unfortunately, this doesn't have a procedure for actually doing it using RTV and any other mods or considerations.
Does anyone have a procedure for installing using RTV only that they would like to share?
Also, I seem to recall people cutting a thin circle gasket about the size of the front cover passage to act as a backup for the nylon ring when installing without the original gasket. Can anyone confirm doing this or give some specs on what they've used?
Thanks

I fitted my front cover using both a gasket and RTV. I was told that way I should be able to remove the cover and be able to reuse the gasket as it would stick and break as easily.
I coated the mating surface with RTV and waited 2 min before putting the gasket on, I then added RTV onto the gasket and waited 5 min before putting the front cover on and bolting it down.
No leaks yet.

I absolutely would use a metal front cover gasket..... you're asking for trouble using just RTV. Not an area I'd want to screw around with potential leaks for obvious reasons

Or just use the RX-8 metal gasket. It is reuseable, it will not leak, and if oil pressure does manage to spread the front cover away a little, the gasket isn't going to disappear like an O-ring will, so you never lose oil pressure, keeping your engine alive.
I have had an O-ring disappear when using just an O-ring and RTV. I found the O-ring in the oil filter pedestal. Unfortunately it was too late and all of the engine bearings were trash - engine made a max of about 20psi pressure.
I'm super cheap, and I spend the $11 or $16 or whatever it is for the part. Cheap insurance!

IF you use The Right Stuff it would work Great. I use it to seal my oil pans and never have any leaks. Even with a motor making 500+ hp and still no leaks
I have used the mazda factory paper one using copper gasket spray on both sides installing when tacky. Ive dont this for the past 8 years with no issues on any motor.
The newer gasket is a cleaner install for sure
