if the OMP on a s4 tii fails, how can I quickly block it off TEMPORARILY (as in long enough to dump some oil in and get home) with nothing but a socket set?

Project84

you don't need to block it off if it fails. It just won't send oil to the oil injectors. What symptoms is your engine having?

powrdby13B

it's receiving too much oil by a long shot... as in smoking like a bitch

Project84

Don't think you can block it off without a block-off plate. If you remove it and don't cover the hole, it will leak on the ground.

how do you know it's the mop?

powrdby13B

it's a theory I have LoL... but if i block it off magically, I figure there's no possible way too much oil can get into the engine (when cars smoke... tends to mean they are burning oil...), plus I'll premix, got almost a full tank of gas.
In that case, where do you guys find OMP block off plates? Not driving it for a couple days is okay i guess, got other cars to drive... I just made my own for my NA...

Project84

Yeah, could be a bad oil seal on the rotor. I know thats not what you want to hear....

If its a turbo, the oil could be coming from the turbocharger.

Have you ever considered removing the four banjo bolts and installing *normal* bolts in their place? Just a thought. Never done that myself. Seems an easy solution.

powrdby13B

hadn't considered that... Oh well, not a big deal
Still, where can i get a fsckin block off plate for the omp? Don't have the tools to make one here...

http://www.2751engineering.com/2751parts.html the best place you can possibly get them. Just ordered mine on monday and by tuesday they where shipped. Your welcome

powrdby13B

sounds overly sneaky to me, hailers
Do turbos have the same size bolts on the omp as NA's (s4 all the way)?

powrdby13B

thanks, hondahater!
That's awesome...
We're done here now LoL

Project84

Replace the bolts on the pump itself or the ones on the engine side? If you replace the engine side, its not going to prevent the pump from spiling oil on the ground. If you replace the bolts on the pump side, you'll still need to block off the ones on the engine side to prevent a vacuum leak.

powrdby13B

owned.... maybe we're not done :-P

if the pump fails then it should starve the engine for oil not supply too much, if the vacuum hose comes off of the injectors then it can cause too much oil to be injected but under boost it would starve again because of the positive pressure in the intake chamber and cause oil to be sent out the vacuum hose connector if the valve has failed.

you can simply put bolts where the injectors used to sit, that is what i did with mine and it seems to be holding up just fine. you can make your own block off plate by getting some thick aluminum bar plate at a hardware store and cutting it with a dremel and drilling the locating holes and sealing it to the cover with silicone. simple solution is to put regular bolts in the OMP where the banjo bolts were to block the OMP oil flow, i pulled mine off completely because it was having sealing problems.

but to tell the truth, i don't think the OMP system is your problem.

powrdby13B

mmm what do you think is wrong then? It started doing this while i was driving, as in fine one second, effed the next...

RotaryEvolution

the PCV system could have a problem and overpressurizing and blowing the oil into the intake, the cold side oil seal on the turbo could be effed or lastly the oil seal o-rings in the engine cracked and are leaking internally.

could possibly be the oil injectors but that is the last thing i would suspect.

HAILERS

The banjo bolts that feed the oil to the injectors are the bolts I'm talking about. If they are NOT banjo bolts.......and the fitting on the end of the four lines is still attached with the bolts......what is there to leak?



Glad you brought up the *vacuum*leak. For people who remove the oil injectors and put a bolt in place of them, you've just lost part of your bypass air for idle when you dumped the oil injectors Spider and capped that source of filtered air from the area prior to the throttle plates. Congrats.

powrdby13B

you mean the turbo could be leaking into the exhaust? that would suck... But with no power stroke, it would be a darker smoke wouldn't it? This is white, like it's burning oil...

RotaryEvolution

hmm, way i see it is the vacuum pulls the diaphragms on the injectors closed to block oil flow when vacuum is high, the vacuum goes nowhere so how can it be lost? my engine idles smooth as glass, no rich or lean conditions.

HAILERS

****the vacuum hose comes off of the injectors then it can cause too much oil to ****

No. Thats not a Vacuum line. That is a source of filtered air that comes from infront of the throttle plates. If they fall off, the only result will be the air that is being sucked into the rotors on the intake stroke....won't be filtered air.

There's a free download of the fsm on the web. URL is on this site.

LOL yeah, it's the big hose on the front of the TB...

thanks Hailers, i know it well. dunno if you are trying to be a jackass or what...


the air is bypassed and taken in during the intake cycle, this amount of vacuum is miniscule and can be compensated for easily if it even needs to be. blocking off the ports completely will mean no unfiltered air will enter the engine.

powrdby13B

so hailers do you think it's PCV or something like that or some OMP related problem? Can't work on the car right here right now so i'm trying to get all plausable problems taken care of so i can just fix it...
