You can cap the nipple..... with a cap. You'll need to find one that fits, there is no mazda part # for it that I'm aware of.

 

HI

Thank you for answering, is it possible that oil came out on this pipe?

Filipe Azevedo

 

What is that nipple for? I've never seen it before.

 

Crankcase ventilation.

 

Yes, because it is connected to the crankcase.

 

Yes, some. As for a cap, take an appropriate length of water hose that fits tight on the nipple (about 3/8ths inch I would guess), place a tight fitting bolt in one end, clamp it and clamp the other end on the nipple. Kind of ghetto, but they are reliable caps.

 

Oh, that one. Thanks.

 

Make sure you degrease everything after fixing the leaks. Oil will destroy rubber components with time.

 

Hi

Call Ray at Mazda Malloy, he told that that nipple doesn`t do anything, also he said that Mazda has a cap for it , almost 3.00 USD i guess this cap will do the job, right?

What i will do its

1 - Fits a lower intercooler hose
2 - Change the O-rings in filler neck and pedestal
3 - Bolt the banjo oil lines - if necessary
4 - Put a Cap on that nipple

I hope this will fix the leak, that is becoming boring

Thanks for all the help, it will take some time because i will be waiting for parts unless someone has a used, but good condition lower intercooler hose to sell and send me.

Thanks

Filipe

Thanks

 

Filipe, we may have an extra one laying around the shop. I'll be there soon and look around..... if I find one I'll send it to you for free, just pay the shipping

 

If it didn't do anything, you wouldn't need a cap for it. The FD has a different means to vent the crankcase which is why it's not needed. It is used on earlier RX-7's.

I don't know what automotive shops you have in Portugal. In the USA, most auto stores have a HELP! section which has little rubber caps, electrical fuses and other small bits that generally break or fall off cars. You can usually find rubber caps of all sizes in that section for very cheap.

 

That is just great. Please tell me somethig when you have it and i have Pay Pal.

Thank You again


I understand now, if it is a normal small rubber cap, i can found it here.

I like my country off course, but sometimes i wish i was born in USA, because auto parts are everywhere and prices are even better them here.

And i must say that if you go to a Mazda Dealer in Portugal you will see what vendors will say about this car.

"Its a "unknown" car", sold about 6 cars back in 1993, only 2 Euro spec (and i have one) the others are USA and Canada Spec.

Mazda dealers said that they never open a rotary engine, even the last Rx8, they also will say that parts are rare and not available" and if it wasn`t good enought, expensive as well....
I have here an example, i was searching a Mazda Dealer over here and ask just for information how much cost a brand new rotary engine for a 1993 FD Rx7.

I made the same question to Ray at Mazda Malloy and he told me near 3900 USD with core.
In Portugal it will cost 7750,00€ with or w/o core plus 20% VAT, wich means it will cost at total with tax fees - 9300,00€ or 12555 USD at todays exchange rate (more or less)

I wish for example we had a Ray here and your prices as well

Thank you guys for all the help

Honestly

Before you fix leaks that don't exist, spray down the pedestal and banjo bolt with degreaser (brake cleaner, etc). Then run the engine and see if they are actually the things leaking. No need to make unnecessary work for yourself.

 

Hi

While iam waiting for the lower intercooler hose to come, i search on forum for another "oil leaks" and i found this thread

https://www.rx7club.com/showthread.p...light=oil+leak

Is there a possibility that i might have some bad or mixed vaccum hoses?

Iam asking, that because today i call the previous onwers and he told me that a few months ago he worked on the rats nest, he also said that it was dificukt to see them and he said the it should be ok.
so i would like you to help me on these questions / doubts

1 - If somes vaccum hoses are exchaged/ or in a wrong a position, is a possility to happen problems like mine?

2 - What i understand about the nipple in the intermediate housing, it is for engine breath, correct? but oil can not go out throught that?

3 - Today only start car for a 15/20 minuts and i found that behind the air box, was caming a exaust smell in that place.
I couldn`t find anything or see where it was caming, but can it be from the down pipe (after market), that might have a leak?

5 - I stopped he car and an strange sound was caming from thre

6 - What is / do the OMP and where it is located - oil metering pump?

7 - What is UIM, dont know what that means / what that do / where is located

For some of view this is normal, but for me this is my first rotary, and i want to understand it to make it reliable and enjoy it.

Thanks

Filipe Azevedo

 

"For some of view this is normal, but for me this is my first rotary, and i want to understand it to make it reliable and enjoy it."

You might want to reference the FAQ at the top of the 3rd Gen section re UIM , OMP, and other useful general information. OMP is the oil metering pump. It is located on the lower right side of the block just behind the main crank pulley. It feeds oil into the combustion chambers via oil injectors. You may also want to check the vacuum hose maps which are all over the forum to see that your hoses are routed properly.

 

So, did you fix your leaks?



I've had a leak from the area around the filler neck for a several years, and I'm 99.9% sure that my oil filler neck o-ring(s) need replacing. I think I removed or loosened it when I was trying to remove the spark plug wires from the coil packs and that made the leak even worse.

My question, if you don't mind; Are there 1 or 2 o-rings for the filler neck? I haven't looked at the neck closely for a while, so I forget exactly what it looks like.

Oh, thanks for doing all of my homework, gang!

 

Oil filler neck has 1 o-ring. The oil filter pedestal has 2 small o-rings. TBH, I haven't use an o-ring on the oil filler neck in years. I just use a bead of RTV.

 

Hi


I found today the nipple between the rotors was the cause of the leak and nothing else. Put a cap on it and will drive it as soon as time change for better days.

Thanks all for helping, i think that will end my problem, but if not i wil be here again to ask you some help

Thanks

Filipe

 

Thanks, Mahjik!!

 

Let's hope that did it! I'll have to take a look at that on mine too.

 

Hi

Sorry the delay.

I put a cap on it - Mazda part number 2306-10-481.

It resolve my problem. I also glue it and put a clamp to secure it on place and that`s it. Fixed!!

Thanks for the help
