Hey OOT, dont forget to install that header when you put the new engine in. Port it too. You can do it, I have faith man.

Edit: Angie says she would be willing to donate a dollar to help out your cause.

That sucks, do you have another car to drive to work?

OnlyOnThurs

ill defeintly put in the new header wit hthe new engine. Oh and tell angie thanks...any thing helps LOL!

yeah we got another car....still sucks though...i used the 7 to go to work as my daily commuter. Juts gotta get it fixed now.

OnlyOnThurs

thanks for the heads up....i didn't even think about this. It has not felt the same the past 2 months. Sometimes it felt like it was starving for fuel when i was on the highway (between 60 and 80). And yes i definitely do NOT want that to happen again lol

Damn Cello, that sucks. I've got a 12a you can steal the housing off off if you need them, hell you can have the whole thing if you need irons too. It's blown, no compression on the rear IIRC.

I got a rebuilt and street ported 12A engine with 0 miles. I used a atkins master overhaul kit and racing beat streetable porting templates. Also got a header similar to racing beat but not a crappy pace header. I lube and turn the engine over every few days to a week to keep things moving. Will sell both together for $650 without shipping included. I just lubed the engine again today and the compression is pretty freaking solid for a engine that isn't even broken in yet.

Kind of sounds like what my first engine did, except mine started burning oil like crazy, and then lost compression on the front rotor. After the first dud of a replacement engine (which I got ripped off) and ended up not using, I went to Pettit racing and built one from parts. I still have a whole 12A worth of parts sitting around if you need anything. I have a set of Atkins corner seals/rx8 springs and a new set of viton oil control rings somewhere. I think I have new oil seal springs somewhere as well, let me know if you want them. Most of the hard bits (housings, and irons) are trash because someone couldn't port for ****, and it had RA seals in it which I don't trust.

Time to bridgeport that bitch.

Thank you guys for all the things you are helping me out with. I will let you guys know if i end up needing any of the stuff you have offered. And to FELIXISGOD29x ...that is an amazing price for that 12a!! but man shipping to texas is gonna be a bitch......

Sorry it turned out this way, pal... Good luck with the rebuild.

May she come back better, stronger, faster...

I would try a SeaFoam treatment or ATF to be sure it is not just a seal sticking due to carbon. For ten bucks it is worth a shot.
Good Luck

Just remember she'll come back better than ever.

Any reason for the death? How many miles do you have on it? From what I know it is odd for an N/A rotary to just go out like that. You sure you didn't overheat it? Was your metering pump functionary?

DivinDriver

Nothing on the front = at least two seals with issues (stuck or bad).

If only one seal was shot, you'd get at least one compression face still pumping.

OnlyOnThurs

the engine had 159k on it.....original 12A. No it did not over heat. From what i can remember yes the OMP was working properly. Like i said the past month or two it has felt like it was kinda starving for fuel at highway speeds only...it did not have the usual kick like it use too. And nothing like a clogged up fuel filter...this felt different. Someone mentioned it may have been running lean...how the hell do i check for that ?


And about the seafoam ..... i did sea foam her about 2 weeks ago before i filled her up. Down the gas tank not the carb.

Vashner

Buy rusty.. she's only $500 and in San Antonio. I just put a new ad in classified.

OnlyOnThurs

only 56k on the motor?!?!? really! any leaks on the 12A at all? Runs good?

Just no interest in my motor. Thats fine, she will sell someday. - Nick

OnlyOnThurs

reading this again reminded me of a bonehead move i did recently. If the 12A did infact blow because it ran lean then then it is my fault then. Some time back (3 months approx) i was running into an issue with the car idling very low (100 -200 rpm) and i went to go turn the idle screw to bump um the idling well..i turned the wrong screw.....i was moving the air/mixture screw way too much before i realized wtf i did. Now i don't know much about carbs so i tried to correct my mistake but i really did not know what i ended up setting it back at. I finally did find the idle screw and i adjusted my idle after the fact. Could this have been possibly the reason why i blew out the motor? If it is then what an expensive mistake Hope someone can chime in

air/fuel mix screw only affects idle, like 0-1200 (maybe) RPMs. Wouldnt cause a lean condition in your cruising speeds of 3K range RPMs.

If it ate bearings or plates, be sure to ultrasonically clean the oil cooler at a minimum. Or replace it.

thanks for the heads up on this.

Shipping wouldnt be that much, your really not going to find a new motor for that price anywhere!

I wish I was still down there to help you friend o friend

OnlyOnThurs

THanks mang. And about Felix's motor that is extremely cheap.....i almost have the cash for it,.......so if he still has it and i got the cash ready i will buy it. Street ported and a brand new rebuild...**** you can;t go wrong with that price.
