Im thinking about getting the Osiris tune done, since i am done with all bolt on mods.....theres just 1 problem.....OC. I usually have to put in like 1-2 qts every few weeks to keep the oil level maintained. My question is, how effective will the tune be with this problem? Will i be seeing very minimal gains? Is it safe?

I have a 5at g35

 

I don't see the "tune" having any issues on anything. You have a oil burner motor. As long as there's oil in the motor your fine. Problem is with a tune you are prob more likely to rev the motor more. If oil levels aren't maintained you could run into starved motor issues.


But to answer you actual question you asked. No I see any additional issues coming from a tune besides the obvious.

 

Compared to a motor with no OC, how will the gains look like on an OC motor? Im assuming the tuner will have to deal with detonation and have problems with the timing which will result in very small gains. Correct me if im wrong....

 

Call me crazy but why would you want to further strain an already ill-functioning motor?

 

impossible to tell. Everything engine is different on a dyno and every dyno is different.

2 perfectly healthy motors could produce 2 completely different gains with the same addons.

More than likely it will produce "similar" gains to what a normal motor will unless the oil consumption is due to the rings not sealing properly therefore your cylinder compression is lower than a normal engine (which would reduce power).

i vote spend the money on fixing the issue and no the tune. It's eventually going to have a serious failure and destroy some bad things.

 

good point. I had a compression test done not too long ago and the compression came back normal in all cylinders. I can probably have another compression test done before the tune to make sure everything is ok i guess.

Honestly, if i had the funds right now to drop a new motor or build it, i would do that in a heartbeat.

 

Why tune an oil burner? It like putting makeup on a pig.

 

If you don't have the funds to replace a dying motor why would you risk any more harm on it? Oil in the combustion chamber kills power btw.

 

There is a reasonable chance that you just have a clogged valve cover drain and/or a malfunctioning PCV valve and are pulling excessive amounts of oil through the plenum. Look up the catch can threads - install a DIY one, and see if you capture a lot of oil. If you do, you can try to change one or both of those parts (a new pass side valve cover comes with a new PCV valve, but you can get a new PCV valve for $15).

 

When i was trying to get the engine replaced under warranty, the dealer replaced the valve covers to see if that would fix the problem, but it didnt.

 

quit milling about and just do it already Raj!!! LOL

With the uprev tuned throttle and fuel map massaged, you're certain to 'feel' a good difference in normal driving -- that's the biggest part of uprev even more than just gains, but the only possible downside is peak numbers less than you hoped.

My only suggestion is install a good catch can and pop open and clean the oil out of the plenum before strapping it on the dyno.
