Wow, I can't believe someone actually went thru the trouble of removing the lines from the OMP and shooting them full of decarb (assuming that was decarb).
Hope you don't spring a leak now! Those banjo joints are very temperamental.
RE: OMP map -- I cranked mine up about 30% across the board. With the 4AT there was no consideration (apparently) taken into account for its 7500 RPM redline. I rescaled the tables to more appropriately match its operation

I did go through that trouble, because I wasn't consuming oil like I should.
Here we are almost a year later and they still do not leak, and I consume 1qt per 1k miles, just like my old FCs, just like I wanted. Nothing wrong with getting a little creative and saving cash (or a lot of cash since I probably saved my engine from a early death).

ok so 2 days later update:
checked the oil level today before leaving work and saw that i burned through almost a quarter on the dip stick since sunday. roughly 120km.
so it looks like were back to normal. just going to keep a very close eye on it and hopefully the lines wont clog again. i also hope that i didnt ruin any internals either.
im thinking of adding some seafoam to the oil a few km before the next oil change to run through the system

. Worked fine on all my Fcs. I change plugs yearly and do not have a cat.

Can someone give me some tips on how to put the OMP back together ? I Pulled mine apart and now realize I should have taken more care and attention with it

Cleaned my OMP lines today from top of the engine bay by removing battery plus battery tray.
Seems to be much easier as by removing the passengers wheel and access from the underside of the car, since handling of the lines and the cleaner from top is clearly visible with sufficient available space.
This first method is in detail showed in the UK-forum as per topic:
RX8 Owners Club ? View topic - Cleaning OMP Lines in situ
The access to the OMP lines is really perfect from top.
My 2005 231 hp had 25.600 miles on the odometer and I wanted to be sure that the OMP lines were free.
Immediately I saw that the lines were rather clean and actually a cleaning seemed to be overdone.
Nevertheless since the battery plus tray were removed at that point I cleaned the detached lines by soaking them in injection nozzle cleaner (so called "Petrol Injection Cleaner") since we have hardly seafoam available in continental Europe.
The bolts were easy to unscrew and turned out to be without any debris
With the engine running at 3.500 rpm each line in turn perfectly slurped the cleaner out of a small container filled each time with 3 oz cleaner.
The operation was started with approx. 2 gallon gasoline left in my tank (reserve warning light in operation); I added synth. 2-stroke oil up to a mixture of 1:50 to eliminate the lack of OMP injection during the time that after the cleaning the lines will be completely filled by the OMP. (No problems with starting the engine with 1:50)
After attaching each line I noticed that the lines were starting to be filled by the OMP (incl. some small bubbles streaming) relatively quickly; however cpl. filling will take some time and therefore the 1:50 premix.
(By the way, I regularly premix since new with approx 1 oz per gallon.)

I want to thank you for starting this post in 2011, I became more or less aware for the first time about the importance of free-flowing OMP-lines.
Your report and pictures how you did it were very helpful and was a starting point for me to do the same. Later on I did read the UK DIY-report about this and choose for the latter because of some easier access.
Once again, thank you very much by taking the trouble (and critics/comments) to share your experience on this forum.
For your information: I use a 2mm restrictor in the OMP vac. line some time already.
After cleaning the OMP oil lines I also sprayed the OMP vac. line (restrictor temporarely removed) with WD-40 (advised by a German expert) as I did already once before in order to clean the 4 way splitter/injectors.
However when I did this the first time, removing the free flowing OMP vac. line immediately resulted in a high whistling sound..........this time after 20.000 mls with the oil restrictor it did not whistle, even since I just before cleaned the OMP-oillines/injectors.
However after 15-30 sec. injecting the WD-40 the screaming whistle came back as before. I can not find any reason for the initial lack of whistle except that evt. due to the higher OMP oilconsumption with the 2 mm restrictor may be somewhere in the "vacuumline-splitterblock" there was a stagnation etc?
Nevertheless the higher 4-stroke OMP oil consumption with 2 mm restrictor works perfectly (more oil consumption as desired); further I noticed that by complete blocking of the vac. line the oil consumption increases once again considerable (to much imo.)
After my latest "whistle-experience" I plan to monitor and evt. spray with WD-40 the OMP vac. line more frequently.
(for you information, I always premix with a ratio of little more than 1 oz per gallon)
Best regards, Ruud
