GSLSE Oil Filter Pedestal O-Rings
Quick question, I tried searching around but didn't find much relating to exactly the GSLSE and was curious if it differs from what I was reading about the beehive style oil filter pedestal gaskets.
My pedestal was leaking fairly bad, especially when cold, right at the machined surface that mates. I removed it thinking maybe the gasket was noticeably damaged or destroyed but they appear fine. They were hard to the touch, and didn't move very well/at all. They were not centered over the holes either. When I re-assembled it after cleaning, it leaked much worse. My question is twofold. 1. If I remove/destroy them can I simply use regular properly sized rubber gaskets to replace them or do I need to buy them from Mazda? 2. If I go to the store right now and get some RTV, take it back apart, and then make my own gasket, is that something that would work? Would I need to isolate the two ports from each other? Thanks guys, Gary |
You need new o-rings, dont just use rtv. I have universal o-ring kits that I use for mine, but you can go to most hardware stores and find some to match up. I also rub a little rtv on mine when I reinstall them.
Oil Filters, Oil Caps and Sending Units 84-85 13B Rx7 Oil Gaskets & O-Rings and so on and so on. Every rx7/rotary store will carry them, they are pretty generic. You are gonna end up paying too much for them then having to pay shipping also. |
Thank you!
I got some RTV anyways, but I haven't done anything yet. Kinda glad too because getting to that nut on the firewall side is kind of a pain when everything is covered in oil. Is there any way you may know the dimensions of the o-rings you use from your kit? I think mostly outside diameter and thickness are the two most important dimensions. |
Just take your old ones in to the auto parts store with you. They can match them up at the counter.
As luck would have it, I have my old O-rings here in drawer at work. Let's see... 3/32 of an inch thick, 51/64th's OD (might be 3/4, mine is flattened), 9/16th's ID. And yeah, I put a little RTV on mine when I put it back together. No more leaks. Not from there anyway. |
I bought new Mazda O-Rings for my replacements, but only because I ordered like 20+ things from Atkins for my engine project. They weren't too expensive and I know they're the right fit. I'm gonna have to disassemble and rub some Blue RTV on there now to make sure she doesn't leak now - thanks for the info guys!

I got it *mostly* fixed with new generic o-rings, but I can still see that it is going to leak very, very slowly. I went to Mazda and bought two new OE rings.
Amazing how hard it is to find an air filter for these cars! lol Time to go buy a K&N! |
I installed a pedestal with stock o-rings today and NO RTV! What are you guys thinking?

Doesn't hurt... I installed mine dry the first time, then took the pedestal off for another reason, and thought I saw a bit of oil from the o-ring, so when I reinstalled it I added the RTV. Still had some oil, but I now know that it is from between the iron and housing, not the o-rings. Sigh... And, yeah! Why is it so hard to find an air filter these things? It's just a rectangle, you'd think it would be shared with SOMETHING else out there. |
