Possible New Renesis Engine Failure Theory?
#428
Interesting Rudolph. In that case it would justify my slow 4 stroke oil consumption. I had oil change on 6/2, then I premixed 1 oz per gallon when I had autocross on 6/5, and after that I returned to 1/2 oz per gallon. I checked dipstick on 6/9 and I think I might have read the wrong side of dipstick lol so I thought the level is 3mm below full but it might have been 3mm before the 'top' of the wrong side of dipstick. I then took a long distance highway drive ~400 miles and when I returned the oil level is 3mm below full (this time I'm sure). Yesterday I waited an hour after the engine shut off before I checked the dipstick and it's in the same spot. Then I posted here. Then I thought maybe the oil level increases with time so today I checked again and it's at around 8mm below full.
So if 1. I misread the dipstick the first time 2. The oil consumption on highway is really low 3. oil level on dipstick increases with time after the engine is shut off and 4. premix got into the 4 stroke, then it is still burning oil. I have been driving the car a little soft lately because the weather maybe that will contribute as well. Anyway I will change the injector when I get a chance but I guess it can wait a little longer. (moving to a place with garage now. )
Quite a lot of assumption and quite a lot of rambling. Sorry guys. :P

before replacing your OMP injectors I would try to run some seafoam trough them. That might do the trick..use the OMP line from the throttle body boot:

is picture I posted not clear enough? there is slight vacuum on that line so you can suck in seafoam with it and it should clean the omp injectors..I think doing it is a good preventive maintenance to ensure fully operational OMP nozzles.
from my other thread:
"okay so i tried the OP's idea out and heres my results. I took the vacuum line from the intake accordion that leads to the OMP nozzles. i noticed it had some suction to it but NOT like normal engine idle vacuum from behind the throttle plate. but with my thumb over it it definetly had some kind of suction to it. SO i poured about one tablespoon in it and went to the back of the car and smelled the seafoam being burned so i went and poured about an ounce of seafoam into the vacuum line. the engine started to stumble very slightly so i put my thumb over the tube again and let it build negative pressure and then released my thumb to let the seafoam continue thru the nozzles. Results oil consumtion wise is that my oil level dropped more than normal. BUT by normal that was MY car which has had low oil consumption so now i have stopped premixing and just let it be. as for idle it idles a little higher than 800 now. prior was steady at 775-800ish now its solid above 800-875ish. sorry no compresion tester here."

Sorry buddy, but have you ever had one of these injectors in your hands? If it fails the vacuum test it fails the vacuum test it is because the internal seals have failed. Putting seafoam in them is not likely going to help fix them and sure as hell will not prevent them from dieing. Not to mention there is no real vacuum there. And even if you poured seafoam down in there I doubt it would have enough pressure to make it all the way through the injector. But I have them laying around, I will do an experiment just for you.
Go back and read pages 1-2 of this thread.

what if they are not working properly due to the oil/crud/carbon deposits..either way it will not hurt him to try it before replacing parts. running seafoam trough the OMP nozzles will clean them and their respective lines. it is simple and easy to do..all it takes is a can of seafoam and some time. I would do it 3 times couple days apart by using the 1/3 of the bottle each time since these deposits can be stubborn and it might take more then one try to dissolve them.

You need to take a good look at the system man, you are missing some info. Even if you can get the seafoam to the injectors (highly doubtful) there is no way for the seafoam to get into the omp lines. Not mention the plastic vacuum block that all the OMP vacuum lines feed off of is also prone to getting brittle and I am not sure how well it would take to having seafoam sitting in it.

Whatever man, you are just not getting it. You have never taken this stuff apart so maybe that is why you don't see it.

The oil nozles have a ball and seat type valve in them....
I had good luck cleaning them in an ultrasonic bath and then carefully blowing them out with compressed air
You have to be careful with the air though..you can easily stick the valve open with too much air pressure. If they don't hold vac...try carefully blowing air in them to loosen the ball and you can be good to go. I had 6 of 8 fail the vac test....and the cleaning got them all working properly. I then used some high temp silicone to lubricate the ball valve So far they seem good to go

it is clear that seafoam was getting into combustion chamber trough the OMP nozzles, hence they can be cleaned with it..

It might help...but it won't clean them out completely. It can't access the area the oil feed comes from....the only real way to clean is the ultrasonic bath...like they clean fuel injectors

I am going to try it myself. my point is: if you clean OMP whenever you seafoam your car (which should be at least once a year) that will prevent OMP clogging in the first place..just like with everything else prevention is the way to go!

Hey 9k,
In your first post you recommend replacing the omp oil lines, with what?
Did you use the same OEM lines purchased from the dealer or did you use something else?
(admittedly I've not spent the time to read this entire thread)
I've got my OMP table cranked and my oil consumption (or lack there of) is has me ... well ... lets just say I'm keeping an eye on it. (I am heavily premixing atm)
I've been to onlinemazdaparts.com and mazmart.com and can't find the oil injectors.
Where do you get these things or are they called something else in the parts world?
Thanks .... I'm playing my lazy card today (I had one saved up)
