I bought the o-rings and took the beehive off of the block and while I was cleaning it up I found that oil keeps seeping out from between the beehive and the aluminum adapter it's bolted to.
So my manual says not to separate these two parts and my question is why not? what will it hurt if I do? I can't find any pictures of these two parts apart, is it a gasket or more o-rings? Any help would be great as I want to put it back together asap. Thanks!

Most will advise you to toss the beehive in the garbage and install the oil cooler from an earlier 1st gen or from a 2nd gen. I would agree with this advice.

since i've never used the bee hive cooler i can't be for sure but i'd say there's O rings there too. something could also be cracked.

So nobody has ever taken the beehive apart???? Now I have mine off and your advice is to throw it away???? Thanks

I've never had an issue with the performance of the beehive, but a lot of people do tend to look down on them.

To answer your question, yes there are o-rings in there. Many people have taken them apart, and none of us can figure out why the manual says not to.

Good luck...

Beehives are pretty good if you lack the room for an air oil cooler.

Remove three 14mm nuts. Two o-rings exactly the same as the other two at the base of the pedestal. Very easy to service outside the vehicle.

I don't touch the banjo bolt at the backside of the beehive. It sucks when people do because it leaks from then on if the crush washers aren't changed. There's no need to mess with it as they don't leak if left alone.

Thanks, I wonder why my book says not to take it apart? It would possibly been easier to remove if I would have taken it apart that way, but thanks it don't leak any where now!!

One thing to consider is that Mazda only used the beehive for a few years on the 1st gen RX-7. It was done to save money. Before and after, all Mazda rotarys had a proper oil to air cooler. It is easy to retrofit the better cooler.

Thanks for this. My 84 GS leaks quite a bit from the beehive cooler. The Chilton's manual doesn't mention the oil cooler disassembly. The Haynes manual covers it weakly. I also wondered why the book says "NEVER LOOSEN" the three bolts.

elbee7

I don't know why the manual reads like that but if you want to fix the leak you will have to remove those three bolts and replace the set of o-rings inside, they are identical to the others. No big deal!

i see oil dripping from what i think is this thing? could someone tell me about it and what could cause this leak ?

Kentetsu

This is the thread that talks about your issue. The thing in your photo is called the Beehive...

JRTODD2

okay thank you , im new to the site.. im just trying to fix this problem. what would fix the leak ? and how costly is it ?

Tall George

You could reseal the beehive unit with new o-rings, retrofit a later air to oil cooler, or install a new beehive. Cost is dependent on your approach to fix. I would start by fixing the unit you have with new o-rings.

JRTODD2

Could you give me the model number for the o rings ? and will a auto parts store by me carry them? like o reilly's or auto zone ?

and also, my rx7 is just past 200,00 miles , any problems i should be looking for ?
