I cracked my actual oil pump when I was messing with my BSE install, I got impatient and am paying the price. I can't find a single vendor anywhere that sells just the pump. They all sell it only with the frontcase as well and are 150+ for one. My front case is fine, but I do need that pump. I have searched high and low to no avail, is there anyone that sells just the pump housing? I'm really at a loss on this...
 
The actual oil pump is just two gears and a back cover. They usually sell it as a unit because the front case and back covers are the most likely to wear.

Did you actually mic the front case to check for clearances and runout, or are you just assuming it's ok after a visual inspection?

To be honest, I visually inspected. I assumed there's something to measure, but my haynes manual doesn't give any actual specs to measure to. Plus nothing aout it has changed, so I figured it should be okay.

Are you implying I should just buy the case and move on with life? Even if that's what I should/will do, still DOES anyone even sell just the back cover? At this point I'm interested just to know that haha.
 
try ebay then, people usually sell used oil pumps. granted you are still buying the whole thing but substantially cheaper and you could just pull off what you need.

that and its in used condition. otherwise they only come in assemblies.

well... that i knew of until the post below:ohdamn:

Here are the gears. I'm just giving you the whole list.

JNZ Tuning has them too.



Do you mean the bulge that is on the back of the case, you need that part? If so, I would contact Stangmurdera or Garymitsu to see if they could pull that off a spare case they have.
 
Personally, I would just buy a new set. What's $150 compared to the price of a build/rebuild?

While I'm certainly not arguing, and I've seen your name around enough to know not to argue with you, honest question, how would only having a new pump housing be more dangerous than when I took my housing off to change balance shaft stuff? Is there some kind of special mating that has to take place between each front case and pump that I'm unaware of? I really don't see why replacing the pump housing alone (provided I could even get one, which it seems I can't), would be risky at all. Any insight?

LOL

Argue away... I learn something new about these things every 10 minutes. :)

It depends on how many miles are on it. If it's fairly new, it shouldn't matter. But if it has some mileage on it, then yes...the cover and gears will wear as a set.

The only real way to know is to mic it.

Fair enough, it's not remotely new and has clocked near 150k and that's a good point. Considering how hard it's turning out to be to find just the cover, I think I'll get a whole new assembly and move on with my build.

Thanks very much good sir.
 
The "Oil Pump" on these cars consists of the front cover, the cover on the rear of the front cover, and the gears. You don't have an "Oil Pump" without the front cover itself.

The front and rear covers are machined together for the tolerance you need between the two (and between the covers and the gears when assembled). Thus, you won't find a "New Rear Cover" for sale by itself. You do *NOT* want to just toss a new rear cover on from another front case/oil pump assembly and expect it to work.

As Paul is hinting at, and others will surely chime in with, you're rolling loaded dice (in this case--against you) going with anything but the OEM pump.

The beck/arnley and oem hyundai pumps are actually real good quality, i have ran nothing but those 2 for years.
 
Yeah, I'd definitely replace it for a new build then. :)



Paul... the Topline pump assemblies are right around that: EXTREME PSI : Topline Oil Pump Assembly

(I see what you did there though. ;))

That's exactly what I was referencing. You think the topline would be fine? I don't have huge power goals, and I am on about as tight a budget as it gets. Any reason to take nothing less than OEM here?
 
I've used the Topline pump with no issues, but it's probably hit and miss. OEM would be better of course, due to tighter quality control. You just have to weigh the extra cost against your budget and the risk of a pump failure.

With that said, I've never heard of a Topline pump having a hard failure (that I can recall anyway). Not that it hasn't happened, but I've never heard of it personally. I doubt it would be any more likely than any other pump failing, other than an OEM one. I think a more likely issue would be failure due to deleted balance shafts and using the wrong stubby shaft.

I'm with everyone else on this, replace it and move on. The oil pump shaft spins freely inside of its housing. This wears down and without checking the actual tolerences on it I would, without a shadow of a doubt, REPLACE IT. It is almost if not the most critical part of your engine and its longevity.

Be smart :p

Yeah man, I'll be doing that after hearing all these guys. Definitely what I'm doing. Just got another paycheck and ordering it now.

Thanks everyone for the help, I really appreciate it. Need this car running before snow's on the ground so I can get off my motorcycle LOL.
