The lines that carry oil from the pump to the cooler have busted on me. I must have driven a good 4-6 miles with no oil and didnt know it. Car is still running though. I wont start it now that its home. I was just wondering if i can premix and still drive it. Id prefer to do this as itd save me a lot on towing, but its not worth the risk of possibly causing more enginge damage. my tank is like 3/4 full i could get enough fuel to fill it and premix with that. Would that be safe?

 

absolutely not. that oil is mainly for the eccentric shaft bearings not the OMP system, if the engine still runs feel lucky and don't press your luck but it still may have been damaged but you won't know until you fix it and drive it.

replace the lines before driving it again.

 

would you happen to know what size braides line I would need to replace the old stock ones?

 

-10 is the commonly used line, but it's not as simple as just buying them (unless you buy a set of prefab lines from Mazdatrix or Racing Beat). See the topic in the Archives regarding stainless oil cooler lines.

 

Oh my god.... Did anyone else read this? Or did I miss-read? You are asking if it would be "OK" to drive without oil lubricating the internals of your engine as long as you put some premix in to help lubricate the seals?

I am dumbfounded.. Seriously How did the lines break in the first place.. They are like triple braided... I can understand seepage but a full on break?

 

They tend to rub where they go by the radiator mount.

 

premix because of a broken oil line...?? really.. how dumb can people get. premixing is for when removing the OMP. not the oil lines.

 

Hey, not everyone is as mechanically inclined as you oh masters of the wrench. At least he asked. I can see how the OMP and the oil cooler systems could be confusing to someone who doesnt know the cars so well.

 

+1. Don't bite his head off, fellas.

Original Poster: The oil cooler lines basically take oil from the motor, put it through a radiator-type deally, but instead of keeping air flowing across it to cool the stuff that cools your motor, this thing has air going across it to cool your engine oil. If one of the lines is leaking, or exploded, then the oil won't be getting back into your motor, once it exits the hose.

Bottom line.... GET YOUR LINES REPLACED! Racingbeat and Mazdatrix both sell stainless steel braided lines.

If you ran that bad boy out of oil while running, you've no doubt chewed up the bearings inside. Go ahead and plan on needing an engine unless you are a miracle worker.

The main oil system works just like any other car...if you run out of oil, you grenade the motor.

The secondary oil injection system, the oil metering system, is rotary specific, and lubricates the apex seals and rotor housings only. The engine can do without this for short periods of time with no real affect. IF you eliminate the stock system, you run the premix to take over.

The 2 systems use oil from the same place, but that's where the similarities end.

 

 

IF you start it up and it seems to knock like a piston engine and have an odd exhaust note, you've definitely damaged the internals. Just fyi.

 

i dont recall a knock or anything strange at all. but i havent started it. i can probably get lines before i have to move it. (in ny you have alternate side parking everywhere. your car cant sit for more than a day or two usually) I'm really worried now. This motor was built last week. And for the same reason. but last time i drove for a while and didnt know it had busted. Of course I got a new set of oil lines last time. I wasnt expecting this at all

 

corksport had lines for like 60 bucks cheaper than anyone else. and they're sold out. everyone elses is like 200 bucks. thats a bit expensive for some lines, but the stock ones obviously arent holding up

 

You need to fix your oil pressure gauge as well, as if it was working, you should have seen it after the first mile.

But like the above replies, I would suspect that the bearings are toast or near toast. If the motor was just rebuilt, pull it now and replace the bearings (and other damaged parts) before everything has set up and you will need to buy more than a seal set.

Running without oil in a rotary is like a piston engine running without oil in the crank shaft. The MOP only provides oil to the seals, not to any bearings or bearing surfaces.

 

FWIW I've seen them EXPLODE onthe track in an TII--->FB car we built...the pics are of just how far and wide that baby pissed out.

RB oil cooler line - $196US
Complimentary under bonnet rust-proofing - priceless

 

One time I slapped a motor in a car to see if it ran, THe lines had been cut, so I just clamped them together... I got it running and tore off down the road, about the time I shifted to 2nd gear all this oil splashed up on the windshield and I shut her down... That was pretty funny....

 

They are under pressure so they tend to just pop open i think. When mine broke i started up the car and it ran like **** and oil pressure was low so i turned it off and checked the oil. It was way low so i added some oil just to have it dump immediately onto the ground. That was one of the few times that my GXL has broke down beyond driveability in many years of daily driving. Had to wait till i got both new ones from mazdatrix to drive it but no damage that i could tell. Replacing those things was a pain too, so replace them both while your at it even if the other looks fine.

 

oil...

 

my lines where great until I descided to race for the first time and bam that bitch blew so bad while I was on my way home I could see oil pouring out of the back of the car. They break believe me Get ss ones. If you don't you will always be fighting this battle.

 

So I got the lines replaced last week. changed the oil and checked it out to see if i could see any copper or metal of any kind. I didnt see anything. The car is running fine also. I'm hoping that all is well but i'm gonna be lookin for another motor either way. I dont like having my car sitting when it goes boom. I'd much rather have an engine sitting that i can throw in
