it will be next week before they can get one to me.

mazda comp should be able to overnight you one.

Glad to know it wasn't me! I had this plus the NPT issue. (Well, my NPT just leaked and was kind of cross threaded in there without sealant) It happened a couple years back. I have a suspicion that this has been on going and people haven't really spoken up about it because this is one of those "parts that should work for everyone" but I could be wrong.

just pulled mine apart to look at it. Looks like the seal has been leaking.

I just noticed the Mazda front seal I purchased from MazdaComp has made in Vietnam on the sticker while every other seal has made in Japan on it. Hopefully no difference in quality.

I have a bunch of idle time and about 30 miles on my fresh build with the stage 2, 1 shim pump and the not-so-good seal that came in it. No leaks so far!!

Here she is, waiting for me to put the gtx3071 on after break in

gl. mine didn't leak until I started driving hard. Hope yours is leak free.

Mine has started to leak a little this is less than 5k on the engine since the rebuild.

Will pull at some point and change over to OEM.

Annoying tbh.

Mine leaked at about 200 miles. And by leak I mean made a fat pool of oil on my belly pan. Swapped to oem and never had problems

Hello All,

We did end up switching over to OEM seals. I'm not sure what has happened with the seals we were using, its the same seals we've been using for 15 years without issues. I have sent a request for information from the manufacturer, but they haven't replied.

All pumps we have going out now have new OEM seals, and we will furnish OEM seals if you have an issue.

Thanks!
Travis

lovin' the customer support.

+1. Swapping the main seal sucked, but thanks for taking care of future customers.

Also maybe just an extra twist of that NPT plug before they get bagged up. :D

I have the Boundary pump as well, however I bought mine from 949 back in 2015....really not looking forward to tearing into the front of the motor just to see if I'm leaking oil too. Motor still has under 1500 miles since the rebuild, hasn't seen boost at all. Hmm.

I'm running a BE pump I got in the past year as well. No leaks yet. Fingers crossed.

Pretty positive I jinxed myself by coming to this thread as I have now recently developed an oil leak that seems to be coming from the spot where the pump would be. Haven't been able to confirm but the pool of oil is right beneath the front of the block. There is also coolant leaking, but that is from a rubber cap that has cracked on the old coolant feed to the stock MSM turbohttps://cimg8.ibsrv.net/gimg/www.mia...2e7ac98ce9.jpg

Had the same issues witha BE pump the seal was the same as here and lasted 1k before it leaked big time. Plus the plug leaked at start up as no sealant had been applied,

Replaced with OEM seal just no fun pulling a ATI damper off with the engine in place. Given the cost of the pump a couple of $$ fitiing a good seal makes more sense along with a bit of attention to detail.

So if your planning on fitting a BE pump I'd pull the seal and trash it.

I purchased one of these pumps about a year ago. I have only driven the car about 10,000 miles, but in that time the engine would leak excessively. A 6" spot in a few hours time and i had to keep oil in the car to add about every other drive. I assumed it was from an ID-10T error, but had little time to get in and fix it.

About 2 weeks ago i finally got brave enough to pull the engine apart, and i confirmed it was the front man seal on my boundary pump. I could move it with my fingers. It was replaced with an OEM seal and no further leaks.

The leak caused all of the rubber on the timing cover to swell and that led to rubbing and deformation of the covers. My once freshly cleaned engine is a sloppy mess, though i have cleaned much of it.
In short would I buy a Boundary pump again? HELL YES! :bigtu:

Yeah it sucked to have a leak, but I have owned 2 Miatas now, my dad has 4 still. We work n them all the time and the fact is; Seals fail and oil leaks happen. Id rather deal with a bad seal than pick metal bits of OEM pump from my failed motor wishing there was a better way.

It is great to hear that Boundary has seen this response and responded well to it. Great customer service.

He just said he would start using OE seals. I bet it was a problem with his supplier.

Need any help? Where in SA do you live? I am nearish to sea world.

True story, they're still great pumps.

I'm near the Forum. I'm pulling the car to Kotzur Racing tomorrow, as we have to weld up that old coolant line to the turbo and finish my IC piping anyways. I appreciate the offer though! I'm sure something else will pop up later on, so I'll shoot you a message if and when
