Unhappy UH OH, bad news with OMP ????

When i rebuilt my motor about 2 years ago, the person who helped me never said anything about having my Oil metering pump working with my Wolf engine management. Suffice to say, the 89' OMP (which is electric) has been disconnected ever since!!!

So has ANY oil been going through the oil injectors?? I wonder because i dont know if they pump works at low volume when disconnected or if it completely shuts off oil injector function.

My car always runs at 88 degrees C because of my huge radiator, but the oil temps have always been high (200-210 in the pan on a cool day going down the highway). Do you think this may be attributed to my OMP issue??? I was considering going premix and taking the whole thing off, but i just wonder what might of happened in that time. Its so frustrating when you ask someone a question and they say "its ok, dont worry" when in actuallity it may not be true .

Any ideas ????

It's certainly not *good*, and probably shortened the life of the engine a fair deal, best bet now would to be either swap over to mechanical (pain in the ***) or remove it, block it off, and go premix. Also, did you get your oil cooler flushed ever? If you get mad and want to throw the omp, you can always throw it my way.

Premix now.
Hope your apex seals ane not too badly worn.
A compression check will tell.

Pull the bottom rad cover & clean out all the debris that collects in front & behind the oil cooler.
And of course put the bottom cover back on.

What more do you need to know? The apex seals get lubricant from the OMP lines. No oil there, no lubricant, worn seals. It's not necessarily catastrophic, but you need to start running premix ASAP.

I guess what i was wondering is if the OMP sent any oil at all when disconnected. Maybe it sends only 10% or something when electronically disconnected instead of 100% of what should be sent when electronically connected. Or does it completely shut off all oil flow entirely?

Thank you for your advice though, im going to go premix now regardless and hope not too much damage occured. By the way, my oil cooler is clean and free of debris. I use the belly pan and have foam around the cooler to make sure air is forced into it, but still it gets hot. Maybe the premix will help. Also thinking about going to synthetic oil now that OMP doenst do anything...

uh if the OMP is disconnected I would say no oil got there. If it was mecanical and the little arm was off then maybe a bit would still flow but I doubt it with the electic one.

It stays where it was when you last shut down with it working - 0%.

Excellent!
You can buy a lot of mix oil with what you get from selling your good used OMP & lines

Hmm, thats a good point! Both the lines and the OMP are in great condition. Its insane to me that the OMP is 1100 new. Ill definitely sell it then if someone is interested.

Perfect, just the answer i was looking for. Thank you

So the pump wasn't connected to anything? Just the harness dangling around?

Are you sure the factory computer didn't remain to work it?

It would be something if the installer of that EMS did think about that?

Two years of driving around without a working OMP? I'm surprised your car is still running.

Is your ECU throwing any codes - without the OMP connected you should be seeing codes and be in limp home mode.

Nope, i have a standalone ECU. Im not too happy about the fact that the person that put it in DIDNT THINK ABOUT THE OMP. Sigh, just my luck i guess. Ill do a compression check when i get my turbo back and see whats up. Hopefully it will be ok and i can just go along with premix and such. If its low, ill just pull the motor and redo the seals before anything breaks, its MUCH cheaper that way...

You hit the nail on the head. Just sitting there with wires zip tied back underneith. Partly my fault for not questioning it, but then again i assumed that was taken into consideration with the EMS and all. Live and learn i guess.........

I took it out tonight along with the lines and the "injectors". They obviously werent used very much , so they are for sale if anyone wants them. Ill get digital pics up this weekend

According to Rotary Performance in Graland, TX, the S5 pump still works at about 20% when disconnected. They told me the suction of the engine still pulls a little oil through the lines. I don't know if that is true, but it's a nice thought.

Are the oil lines clear enough to see through? If you see oil in them, chances are good that some got to the apex seals. Without something pushing/pulling the oil through, gravity will pull the oil down and clear the lines after a while.

so the question remains...

do you have to go standalone to get rid of the OMP in an S5 car?

Yes. Nobody to date has created a 'simulator' of the OMP to be able to remove it.

Well at least it was zip tied

Well, there isn't a damn thing you can do about it now. Just drive it like not a damn thing happened.

Possible legal action against the installer?

The installer will just say "I presumed you would premix!"

Well, i dont think they would say that because they never even mentioned premix until a month ago and only because they though its better since doesnt use dirty crankcase oil, NOT because my OMP doesnt work. Obviously they still dont know about this, but i will bring it to their attention.

I would assume that only my apex seals (not necessarily springs) would need to be replaced along with a new gasket kit. Is this true if i found low compression? Ive never "worn out" a motor, they have all broken from detonation and such. Id be happy if the installer of the wolf just gave me new apex seals and a gasket kit and ill rebuild the motor myself, but thats probably asking alot Sigh....... this is why i do all my own work now if possible, no one to blame but myself if something goes wrong. Then again, there is lots that i dont know, so i try and put trust in someone who is knowledgeable.

According to Rotary Performance in Graland, TX, the S5 pump still works at about 20% when disconnected. They told me the suction of the engine still pulls a little oil through the lines. I don't know if that is true, but it's a nice thought.
Thanks for the words of encouragement, it is nice to hope that they might be right. Unfortunately i think they are referring to the S4 mechanical pump. Ill still hope though!

You can always 'donate' your s5 omp to me, hehehe, my car's been out of order for the past 5 months becaues my omp is in limp mode hehe
If it was 2 years ago, i could afford to be nice like that, but now that im a broke *** from school, i cant do that. The lines, omp and "injectors" are on my tool cart and for sale if you would like to buy them. Your helping out a poor college student and keeping a nice 89 t2 on the road (just check out my avitar!)

Again, thanks for your responses...
