Oil Pump/Front Case

[WNNAFLY]

I was wondering if anyone has a picture of an OEM Mitsu Oil Pump, or knows of a OEM only marking on it. I recently bought a 6-bolt that the oil pump was recently replaced but if it’s not OEM I am getting rid of it. The only marking on it is a D.O.H stamp.

Also does anyone know if the Hyundai 4G63 Oil Pumps are the same as an Mitsu Oil Pump? I heard they were and they are significantly cheaper.

I found this OiL pump which is made by AISIN in Japan which is supposibly OEM for Mitsubishi? Has any else heard of this and can confirm they are OEM.

Any help would be appreciated.

Thanks

The lower right corner of the crank seal. Does it look like somebody took a die grinder to it? If so then its a OEM unit that has been remanufactured.

The early Hyundai covers will work. Up to 1994.

P.S. Its not a Hyundai 4G63 its a Hyundai G4CP.

Upto 95 on the Elantras and later (97-98) on the Sonata's with the 2.0L 4g63.

You say the Hyundai covers will work but are they the same at the mistu pumps? I know NISSIN makes OEM mitsu parts, do they make Hyundai parts?

"DO NOT" try to use a 96-98 Hyundai G4CP front cover on a 1st gen.. That cover is specific to Hyundai for those years only.

Yes, the early Hyundai G4CP covers are Mitsu. and they will fit the early DSM's.

Here are the only pics I have of my OEM front cover.

Not sure if this was clear or not but those "Hyundai covers" are indeed Mitsubishi covers. Those earlier Hyundai cars had Mitsubishi motors. Therefore, those Mitsu motors have Mitsu. covers. On the Elantras with the L4/16, you can use the covers till the year 1995, they were 6-bolts. The later Sonatas had the 7-bolt 4g63 till 98'. From 1996+, HMC started using their own Korean made Beta-series motors for the Elantra so their covers are unusable for your application.

Thanks a lot guys, the pictures of the oil pump and the explination of the Hyundai pumps are exactly what I was looking for.

Are the Hyundai pumps that much cheaper then the Mitsu pumps?

 

[WNNAFLY]

Are these Elantras 2 liter or 1.6 liter motors? I just phoned a Hyundai Dealership and he said there are no 2 liter motors in the Elantras pre 95 only 1.6s or 2.2 liter motors.

I got a price on the 96 2L but that is the wrong unit acording to your post.

No Elantras came with a 2.0L Mitsu engine. Only 1.6L and 1.8L DOHC in the GLS models. Either case will work in your car.

Ask for a case from a 94-95 GLS Elantra. That has the 1.8L and it's a DOHC not like the DSM 1.8L SOHC. It's very similar to the DSM 2.0L 4G63 other than displacement (1836cc), it has a smaller bore if I recall. It's actually a 4G67.

 

[WNNAFLY]

Thanks again man for the info.

I called but believe it or not the Hyundai pump was more then the Mitsu pump. Oh well I guess I will bite the bullet and go to Mitsu.

I just got the same pump from the same ebayer. It looks like it's remanufactured since the aluminum is stained in spots, there's scratches and dings, and the marking's ground off to the lower right of the main steal. It looks useable. I'm not sure what it means when they "remanufacture" oil pumps???

Winnafly, you've decided not to use this pump?

Here are the pics of mine:

The emblem on the back seems to say JIC ??

What was the guys signature on ebay? Was it "lilac88880". Because there is a couple of different guys on there.

I don't know what to do, I priced an OEM pump and they are double the cost of ebay ones.

I too am not sure what the "Remanufacture" means with the pump. As far as I understand the gears ware out and so do does the case where the gears are rideing, so I guess they would replace the gears and maybe add more material to the houseing then machine it back down. Both ebay guys say the pumps are brand new JDM pumps...but I do see the oil stains on your pump.

I have just been searching the boards and have read post's about "After market or reman" pumps failing so thats why I have been hesitant to get one of those.

 

[steel_3d]

Yeah lilac8880. I'm gonna call him on it.

 

[Suparata]

That is a TopLine front cover. It is a new unit not a reman one.
As long as you make sure the gears are de-burred if needed, you will be fine. That's of course if you do the assembly correctly. This post might help you.
De-burring should be done on any gears no matter who the manufacturer is.

 

[steel_3d]

Yeah I was gonna do all that.

So what gives it away as a topline pump? I haven't been home yet to compare it with my old one.

Also, why is mine stained and nicked/scratched on the gasket surfaces if it's new?

It's definitely advertised as "New, AISIN, made as OE equipment for mitsu".

 

[WNNAFLY]

Steel_3d

Did you call the ebay guy yet? What did he say to you? He told me they are not remanufactured but are brand new?

I don't think it is a Top Line pump as I have seen one and they look different.

I just got the same pump from the same ebayer. It looks like it's remanufactured since the aluminum is stained in spots, there's scratches and dings, and the marking's ground off to the lower right of the main steal. It looks useable.

thats definately not an oem manufactured one, why? look at the casting of the pump, its almost purely cast, look at the pictures posted above off the one thats attached to the engine already, you see a nice machined surface on it, this one was just machined where bolts needed to go or where it needed to be machined, the factore or O.E. ones are machined all over the place with a nice finish. Dont be a cheapass on the oil pump, get a topline one if anything, they come with a warantee because some have been know to be defective (the factory made a bad batch at one point) or go oem which is aroudn 250$, try mentor mitsubishi, they give 25% off parts, hell http://trademotion.com/partlocator/...8&make=24&model=Eclipse&year=1991&catalogid=1 its 175$ with the discount

 

[steel_3d]

I mailed him, told him this is a remanufactured pump.

He said no, it's new, if I don't like it I should send it back.

I said how can a new pump have stains on the casting and nicks and scratches on the gasket surfaces? Waiting for his reply.


itsme4g63, shit man, that's just the case, the gears are another 60 bucks. With shipping, that'll come to 175 + 60 + 10 = 245. But you're right, it's starting to look more attractive.

 

[clipise]

just go with jackson auto machine. $175 for cover, gears, and all gaskets u cant go wrong. i bought 2 for both of my engines

 

[steel_3d]

Actually the one one jam's site seems to look the same, although it's a small pic. I think I'm even seeing the same JIC emblem on the back cover.

Here's some comparison shots of the one I got with the stocker (stocker's on the bottom):

<img src="http://i2.tinypic.com/xm3go3.jpg" width=800>

<img src="http://i1.tinypic.com/xm3hhs.jpg" width=800>

<img src="http://i3.tinypic.com/xm3hpt.jpg" width=800>

The casting on the front and back of the stocker is way smoother. I don't think it's machined it just seems to be cast differently.

The markings on the back cover are nonexistent.

The marking on the front is DOH instead of DOHC 7 plus milling marks.

The stocker has straight cut gears, the other one helical.


Can ANYONE confirm what pump this is?

I've looked at three new sources:
Karking calls it Hyundai
JAM calls it "made in Japan by mitsubishi's manufacturer"
SBR has the same pic calling it Topline.

I'm comparing certain features of the casting, and they all look like the ebay pump, not like the stocker.

Here's another style I found, which is the same casting as all the other ebay pumps, but has no markings on the front: http://cgi.ebay.com/ebaymotors/ECLI...Z6778QQitemZ8059830259QQrdZ1QQsspagenameZWD1V

 

[steel_3d]

This Topline is the same casting: <a href="http://www.extremepsi.com/store/customer/product.php?productid=18472&cat=889&page=1">extremepsi</a>

 

[ITSME4G63]

Yeah it seems that the casting does look better on the oem one. I believe a 1g 6 bolt pump has straight cut gears while the 7 bolt pumps got helical, but I may be wrong.

[WNNAFLY]

So it looks like this is the OEM Hyundai pump that these ebay guys are selling..

It almost looks like there is only two castings of pumps out there that everyone uses....the OEM mitsu Pump and the Hyundai pump....Even Top line seems to use the Hyundai pump.

I wonder why a bunch of guys had problems with the Top Line pumps....some people swear by them and others say they are junk.

Steel 3D.....are you going to send yours back and get another one?
