Okay so im pretty sure my oil metering pump is leaking around where its connected to the engine does anyone have a picture of the back of the pump, i need to see if the O-ring is a typical shaped item (I have a whole kit of Orings) and can the rear gasket be resealed w/ slicone or is it a special type gasket? also do the lines usually need resealing w/ silicone around where they connect to the pump? I just want to get some info for when i remove it tomarrow and reseal it

thanks,
brendan

P.S. I know most of you guys will suggest Premix but i do want to keep it on the vehical.

 

The o-ring is a fairly small diameter for it's size. I got mine at Mazdatrix, cheap... Wouldn't recommend trying to silicone the gasket- there's lots of little orifices you might plug up when you bolt that sucker down. Took mine off & started premix 'bout 4 months ago, car must not have liked that, she's been breakin down every week now, seems like (different things)...

 

yeah belive me i would be more than happy to do that but i need to get this back on the road quicly. I have gasket paper that i can use and i can spread silicone on the finished product in a way that it won ooze into any orfice like that. anybody see a major problem with this?

 

I can get you a pic tomorrow if you will still need it. However, I can upload a pic of a fresh O-ring tonite. The o-ring, is not really an O-ring at all - its really an oval shape.

Also, keep in mind that the O-ring for an S4 and an S5 ARE different. Make sure you get the correct one. I would not recomend using sealent down there.

 

Yeah, i might just have to take the blow and wait for Mazdatrix to ship well thanks alot for deturring me away from doint this

 

Yeah the S4 Oval rings are smaller.

Since I was given a S5 oring I jusr reused the previous ring with some sealant on the external part of the ring to help make a better seal.

 

running premix sounds like a hassel,
but thats jsut my .02 lates Matt22

 

Well, There's 2 side to it.

Getting the damn OMP lines and OMP washers and stuff right is a bastard.

I just put the S4 Mech OMP on my S4 front housing S5 engine monster and I'm still trying to figure it all out.

I also broke one of the damn OMP lines so I am using one of my NA lines and they are prebent so it's not totally liking it. Those OMP lines are $25++ for each one.

If you can remember to drop a small bottle of premix in your car every tank of gas then it would be easier for the install portion. Also removes extra crap under the hood.
