whats wrong with my car?
yesterday, when i was driving to the ferry, i pushed my clutch in and my car died, didn't idle... but that was really the only time that happened, its idling steady now... but the real issue is... yesterday after i got back from seattle, go to start the car up after it had been sitting for about 6 or 7 hours, and it smokes for about a minute and a half... blue smoke... so i'm like wtf... so i drive home, on the drive home, its not smoking during normal cruising, but it is smoking in the upper rpms(ie above 4000)... so i get it home, leave it overnight... go out there and start it this morning, it does the blue smoke thing for about 10 seconds this time, i only started it to clear out the gas(started it with fuel pump off) so i could ghetto test my compression(three strong wooshes per rotor, and none sound off ie corner seal or side seal(i was concerned about those cause i noticed a weird pattering sound in my exhaust note)... so i put my plugs back in, get it started, drive around... when it got warmed up, there was no more oil at the upper rpm... when i got back in the driveway, i gave it a little bit of revvin, and no oil... what could have caused this in the first place? i'm completely confused now... i don't know what to think... i'm gonna keep watching it tho, keep watching oil consumption, right now its hardly consuming any oil, about the standard amount for what OMP uses... its at the full line on the dipstick... any ideas tho?

I could offer some thoughts on this. For starters, it's not your fault, so get a warranty replacement or rebuild. Most likely a rebuild since you spent so much time on your side plates. I doubt the ports were large enough to cut into the oil seal track because if they were, it would have been evident right from the beginning with excessive oil smoke which would disipate into a steady light smoke any time it's running (some race cars do this with huge ports).
On a video somewhere, it shows somebody installing an oil o-ring with a feeler guage. He said to not push on it too hard because the edge could cut into the o-ring. I've never used anything like that to install o-rings and never will. If Atkins does it, maybe one of thme got cut. A teardown will show what the problem is.
I also reuse my oil seals. The wear mark is around 1mm wide, which is pretty much right at the edge of spec, if not over. I've had no smoke problems at all though.
One thing that is possible is an oil seal spring or two may have been installed incorrectly and is only now letting you know. Again, a teardown will show what the problem is. Good luck.

i'm pulling the motor today, called dan to let him know i'm getting the motor to him tomorrow, he's gonna pull it apart in front of me... i think it should be warrantee... we're gonna replace the bearings too, cause the motor has had a funny squeek from the start, so i don't want to have issues in the future... wish me luck today, bout to go pick up the engine hoist we'll be using... and the wear mark if i'm not mistaken is 1.5mm isn't it? i'm pretty sure thats what rob at pineapple told me, based on his mazda factory spec book thinger... i'm hoping its covered under warrantee, i've tried to do everything right with this motor, i think dan will probly be pretty fair with me

yup, motors out in the back of the truck, i turned the flywheel, and a very nice amount of oil came out of the rear rotor's exhaust port... i really hope this is covered under warrantee, i haven't done anything wrong with this motor

i think while its out i'm gonna get the bearings replaced with some race bearings... and an aluminum FC water pump... and possibly an underdrive pulley(its great having a good paying job, compared to when i first got the motor built and had no job lol)

Ah, so you've narrowed it down to the rear rotor. Maybe the spec is 1.5. Either way, my white truck's were really close to spec when I checked it with the FSM.
One thing that occured to me is perhaps one of the oil seals may have cracked, which doesn't happen very often unless they were abused. They can crack at the thinnest point where the little machined indentation is to hold the edge of the oil seal springs. That'd be great if that's all the problem is. A simple replacement and you're on your way.

I figured it out. The magic number I was looking for was 40 lbs. If I could just reduce the front end by that much, it would weigh basically the same as when it had my REPU's 13B in it. It just so happens that a group size 24 battery weighs about 41.5 lbs, and there is still one of these sitting in the engine bay! If I relocate it to the back, the front end should handle like it did with the 13B in it. I could certainly feel a weight difference with my floor jack. The rear end is like super-light compared to the front; which feels like my REPU as far as effort required to push down on the handle to lift the car. I think I'll need some heavier springs up front.
I plan to break the rear end before upgrading the engine's power. As for your V8 project, better you than me.

Sorry to hear of your loss man. But if they tried to pin this on you, why on earth would you want to give them anything? Take what you can that's useable and give it to someone that cares (like me 
).... I wouldn't give them spit. But that's just me....
Good luck with the darkside.
