There is a rumor on the internet saying that people are using a d16a6/d16z6 oil pump in there d16a1's and DOHC ZC.
People swear they are using them! There not!

I tried a d16a6 Oil pump(same part number as d16z6)
First you have to grind down the part of the oil pump that is in the way of the T belt washer
then that slides on no problem.
All the bolt holes line up perfect.

Once you finish puttin the oil pan/pick up/T belt/covers/valve cover/ wires/ upper cover/turbo oil lines.......
You find out that the passage is a little bit off and there is oil spraying all out the back of the pump from where it doesnt seal!

the only oil pump that will wor is a 89 integra oil pump, I will know this tommorow after the new $250 oil pump shows up from vancover and I try to throw it back in tommorow night.

 

let me know how that turns out because i need a new oil pump for my dohc zc too...was your pump going bad as you were driving it.. i think mine is bcuz its been making a knocking noise and then all the sudden my oil light will turn on and my oil pressure will drop

 

gey

 

89 intergra ls
1.6 dohc is the oil pump that fits and works perfect

 

sweet!!! did you order a oem one or did you get a better pump?

 

there is no aftermarket pump listed as far as I could find.

I talked to my machine shop that builds engines all day and he told me that that oil pump can supply 5 times more oil then is needed.

I got the oem pump

215+tax's

 

were did you end up geting your pump..at your local parts store or some were online

 

I got 187k miles on my d16a1... Do I NEED a new oil pump?

 

I ordered it from acura local, pump sent in from vancover.

For the most part your oil pump will last as long as your engine will.

If u spin some bearings or that then its a good idea to change it because the tiny scratche's in the housing can cause u to lose preasure once the oil is hot and thin.

I would replace your oil pump with any build, y save 200 on a oil pump when you have 2,000 iin internals

 

i just found out i spun a bearing i pulled of my oil pan to get to my oil pump and i found a nice surprise of good looking oil shavings so now i got to get a new set of bearing but im trying to find the best ones i can find...but the only brand i can find are acl or king
