New rebuild flooding and wont start without MMO
Been battling my rebuild in my FD. Stock port. It floods really easy. The only way to start it is to pour in some MMO, it fires right up and I can idle it for 20 mins or so, then i shut it off. If i try and start it again it sometimes will start, or will kinda putt along as long as the starter is engaged. If it doesnt start I can pour in some more MMO and it can idle again. I dont have a compression tester but these symptoms seem like I have low compression. If i remove my sparkplugs the chugs seem to sound fine while cranking. Coolant system seems to be sealed tight, not loosing any coolant, nor is the system getting presureized. I am however burning off a shitload of MMO. I think my intake and exhaust are coated in that **** at this point and burning it off is pissing the **** out of my neighbors. Anyone know what I can do to get this thing working right?

fart on a friends head!!!
this is very odd. . . hope im not too much of a jerk, but is there any oil in it? if it isnt sealing and is relying on mmo to do that job then maybe theres no oil in it. other than that. . . maybe check the map sensors connection (vaccum/plug). is it getting fuel? if not, check all connections. check for leaks. . . check for proper function. . . this is all weird.

when i rebuilt my engine i had very similar problems,,,when you get it idling take it for a little drive,,,the compression is low (i noticed every little bit of driving i did the compression got much better than just idling),,, the problem for me went away as the compression got better,,

yes oil is in the car and i have pressure. Sensor checks ok, vacuum ok. fuel ok, everything is ok.
I got home today, jumped in the 7 and started it up, it was hard to start but it got going, i got it to an idle.... my GF started bitching because the smoke was filling up the house. I suppose i should have told her to close the windows, my bad. So i decided to roll around the block. HOLY SMOKE SCREEN. Anyone who was outside was yelling out "YOUR CAR IS ON FIRE!!!!!" and other drivers just stopped in their tracks wondering wtf was going on. I drove it around regardless of the attention i got, brought it up to operating temperature and shut it off before someone decides to call 911. I think im going to tow this thing to bum **** egypt and let all this crap burn off.

haha newbs
what did you expect was going to happen putting all of that oil in there??
It's going to take a long time for it to burn off. It sounds like you've got weak compression or excess fuel getting in there. Turn it on at night and let it idle for 30 minutes if it's not loud (which I'm sure it is)
Your neighbors are going to hate you, it's the price you have to pay since you fucked with and modded it...im sure it would have been fine stock

Hate to say it, but it sounds like a coolant seal got pinched during the assembly. A buddy of mine had the exact same problem. The outter ring on the bottom came out of the groove during assembly. It was dumping coolant into the oil pan and also burning some off to create the spy hunter smoke screen.
It shouldn't take that long (i.e. driving around) to burn off some MMO in the chamber, so you must be buring something else.

SurgeMonster: im asking for help, not judgement. Hard to tell tone of voice over text but you come off like an ***. I've built a honda 4 banger, and several 500hp honda v6's, just never a rotary. We all start somewhere.
I would normally agree with you there but there is no water in the oil, no oil in the coolant, the cooling system isnt puking itself silly from a bad inner ring, the smoke doesnt smell sweet, only MMO toxic like, and I made damn sure that the seals didn't pinch durring assembly, i had someone slowly lower the housings while I personally watched. Then I made sure they pressed down correctly durring the torque sequence. I know very well the symtoms of a blown o ring or warped housings as that is why i tore it down in the first place.

I disagree with mahjik on this one
I think it's quite possible that the oil didn't burn off yet
It also sounds to me that you are dumping too much fuel and it's a combo of the oil burning up and the fuel. I think the best thing to do at this point is continue to drive it around for about an hour with light throttle maybe taking it to 4k max no boost. I've had it take 30 minutes to burn off oil and get the car to run right after it was flooded. After it starts to run better check the primary injectors for leakage and then proceed to put in NEW plugs and see what happens. go for some non platinums first until you completely solve the problem because they most likely won't last long any way
I guess we all do have to start somewhere you are right
The info on your hondas doesn't really help the situation this is a totally different car...a sports car...and with a totally different engine platform.

thanks for your input. I know the hondas arent relevent to this problem, but I'm only saying I am not new to ripping engines apart. looks like ill take it out late tonight and drive back roads or something. I know some industrial streets nearby.

another thing to check is the fuel pressure regulator. I had the same problem when I put mine in. thried everything and 4 months later replaced the FPR and it was perfect. the FPR failed causing it to leak through the vac line and into the LIM then into the chambers. It also made the car have 50+ psi of fuel pressure.

well, found out the smoke is actually oil. I dont know if my turbos have been damaged or if the side seals are fucked. I installed the side seals to the T from the RA video. Can the omp dump that kind of oil? Id say ive lost a quart every half hour.

i sure as hell hope not, i used tons of lube while installing them and didnt see immediate problems. And if it means anything I used RA seals. I'm going to pull the turbo away from the engine an see if it still smokes.

I found out it was oil because there was oil starting to drip out of the exhaust pipe. Wouldn't this amount of oil make the plugs wet with oil if it was the oil seals? Although there is no oil on the charge side of the turbo, im wondering if the exhaust side got screwed somehow, i had the turbos half way dissasembled when making non-seq mods.

took off the turbos, fired her up and she smoked like a chinese laundromat. Turned it off, disconnected the omp lines and extended the feed lines into a cup and the smoke was even worse the second time, prolly pooling up inside the housings. Oil filler neck also smokes.
Servay says bad ******* oil seal. Gonna have a friend tell me which port that **** is blowing from durring the weekend, then tear it apart. Im going to be a ******* expert at this.

well looks like the side seal rings got stuck somehow. But thats not whats pissing me off as I have found problems far worse. Apparently the corner seals or something scratched the **** out of my side housings, plus the chrome on my rotor housings look faded, i dont know if that is from abrasion or if it was from all the oil. Either way I have a boat anchor and I dont have any money to replace it.

Sorry to hear that, but unfortunately it can be painful and costly to learn how to rebuild motors starting with your own. I hope my rebuild goes ok but I do know there are far to many things I could have done wrong to have it all go right the first time.
