mine is out and i need to change it, i've never done it before. Just wondering if there is a write up for it. I also don't know where it is. Thanx in advance

 

If you already took it off, you'll know how to put it back on. It's as simple as a handful of bolts and trying very hard not to break the plastic lines.

 

i never took it out.....i dont even know where its located

 

s4 or s5? if its an s4 it will have 2 bolts that will need to be removed in order to remove the omp from the engine block. 3 bolts if its an s5.

check out this page and look at the pics of the s4 and s5 omp block off plates. it will give you an idea of which bolts im talking about.

now, the omp is located on the passenger side of the front of the engine. youll see some plastic tubing leading down to the omp.

 

if its out, why not just remove it... install a block off plate and the plugs and start pre-mixing?

 

its an S5, and i thought i'd replace it cuz my engine starts to shut down after a while until i turn it off and back on. Don't know anythig about premixing

 

i see it, thanks for the help

 

This sounds like limp mode. On S5s, you can't just remove the OMP without modifying or replacing the ECU with an aftermarket EMS. Blocking off / premixing wouldn't be a great option for you, since you would still have to have the pump plugged in and tied off to the side somewhere.

The pump itself bolts onto the passenger-side of the front cover. It will have an electrical plug from the harness & four plastic lines that run up to oil injectors on the top of the engine. These lines are held onto the pump by four 10mm banjo bolts. Now, depending on what the state of your engine is, you may have to remove the intake manifold & reinstall the oil injectors and reconnect the plastic lines to them as well. If the injectors and lines are still in place, your job will be much easier.

This is a picture of the oil system for an S5 turbo:http://www.rx7turbo.com/documents/89...oildiagram.pdf. You can find more diagrams in the factory service manual (FSM).

The OMP is # 3 and the oil injectors are # 6. The layout is nearly identical on an S5 NA, if that is what you have.

 

mine went out a few months ago because i put a S4 water pump jacket on which had clearance issues hitting the s5 omp, which in turn killed it over time.. so i went with a Rtek 1.5 ecu chip which removes the OMP instructions from the ecu , and put block off plates.

I now premix, it aint fun at all.. but its a ECU upgrade

There are 3 10mm bolts that hold the OMP on, and 4 clear oil lines that lead to the rotor housings. you should be able to just get a used OMP on ebay or something, and swap the OMP itself without having to replace the lines. Swapping it shouldnt be hard at all, you could do it during your lunch break. Its just a lil time consuming if you still ahve the radiator fan and shouding in the way. I have electric fan so i have alot of room to access and replace things like this.
