I run an F Prepared bodied 79 Limited. I added an oil baffle to my 13b (84 I think), last year. I asked the guys at Mazda whether to use 1 gasket or 2 (above and below baffle). I got different answers. The pan bolts are really too short for 2. Tried it without starting the car. Then took it apart again and removed one gasket. Leaked a fair amount but I managed to "get by". What have others done? It's getting time to finish preseason projects.Thanks

 

jus use the right stuff man

 

try calling or e-mailing Racing Beat or Mazdatrix for suggestions. i remember the Racing Beat catalog suggested using two gaskets, but i don't recall any mention of the bolt being an issue.

i suppose another solution would be to take a bolt down to your local hardware store and get some that will provide the torque and length that you require.

 

With the baffle use two gaskets, silocone & longer screws. I found screws that were just a tad longer. But not to much longer & bottom out & brake them.

 

Just like the previous post use 2 gaskets and run a bead of high temp rtv silicone, the red stuff, and I like using studs instead of bolts. You can get the stud kit from Moroso they are relatively inexpensive and you can tighten down on them alot more than you could a bolt.

 

**** the red stuff, use the right stuff

 

Specifically "Right Stuff" silicone sealer. This "stuff" is way better than your typical generic tube of RTV. It comes in a caulk-type tube and comes with its own little caulking gun. It's impervious to oil to the point where you don't have to wait for it to set up, you can put it into service right away. (You still want to get the sealing surfaces very, very clean with brake cleaner or lacquer thinner first)

I never use a gasket on the oil pan. If you think about it, the oil pan is not only easily distorted, being made from thin, 26 year old sheetmetal, but also it is trying to seal against six discrete surfaces, and even though Mazda did a fairly good job of keeping everything close, it's still never going to be perfect.

 

You got a part number for the stud kit that will fit the RX-7?

 

Thanks all,
I had called Mazda, that's where I got different answers. Use 2 gaskets, use one and silicone, use only silicone. It was frustrating. I tried at my local Ace hardware, but was unable to find screws the correct length for double gaskets. I used a Permatex silicone sealer and cleaned all surfaces with brake cleaner. Peejay, is the "Right Stuff" carried at one of the chain parts stores?

Part number is Oil Pan Stud Kit No 38366

RexRyder "**** the red stuff, use the right stuff" instead of cursing me out why don't you tell me what the "right stuff" is I am always open to suggestion and willing to try things if they do work better. I'm just giving suggestions out of my experience and I have never had problems with a leaking oil pan with the method I use.

 

I believe we get it from NAPA.

Thanks, I'll check at NAPA for the stuff. Thanks to all for suggestions. Now have to make time to pull it apart again.

 

just go to kragen

 

they also sell "the right stuff" at O' Reillys and Advance Auto Parts.

 

Following the suggestions of several helpful folks, I used The Right Stuff. It sealed the pan as needed. It sets fast, so have to move quickly. I also used it to seal the rear end. No leaks.
Thanks for all the good suggestions.
