Boundary pumps, what seal do they come with, pics inside
#43
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.

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!

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 turbo

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!
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.

True story, they're still great pumps.
