Rear Rotor is gone. Teardown

well it happened tonight about 11pm and I am alittle said but I didnt waste anytime.

here is the wankel now in the garage at 1:30am






upper intake is off and harness is off. I will be pulling the motor out tomorrow after draining the oil and coolant. So I will be rebuilding and Porting it out myself.
wish me some luck. I have to pull out a loan as well sorta broke.

111,000 mile and ran like a champ. RIP original motor.

Ah, this is where the advenure begins. With the low mileage, if the the rear housing and rotor aren't torn up, most of the hard parts should be reuseable. Post pics of them when you have the engine torn down. Good luck.

the lower intake is off. as well as the header and one apex seal went out. the rotor looks to have some damage on it and I can feel some scoring on the rear housing. getting the hoist tomorrow, guess today, and will have it on an engine stand. I willbe asking for alot of help from you rotor heads who have rebuilt engines.

there is a small voice inside my head that keeps telling me you get a 13bt, v3 megasquirt, and FMIC. I will figure out what to do by the conditions of housings.

Since good SE housings and rotors are getting harder to find, picking up a rebuildable FC engine may be your best choice in the long run. Selling off the good SE irons and housings will help offset your rebuild costs.

Yea, since you're pulling the motor anyways just do what you need to do to prep it and throw a 13b Tii in it.

hey, if the apex seal side pieces (little triangular corners of the apex seals) are the same as those in a 12A, and you aren't going to reuse them, please let me know because i need them for my gokart engine. Turns out it can use 12A seals, i just need these end pieces. PM me if you have some, thanks alot, and sorry to thread jack a bit lol

Those angle bars work great, I use mine everytime. The're a must when doing the engine and tranny together.

Hmmm I haven't used one of them when pulling my engine and trans together. I just lift the engine from the front and allow the front of the engine to come out of the engine bay at a heavy angle. Tranmission follows, then with a helper you can move them through the air and reangle them to put them on the ground, bench, engine stand or whatever.

Not saying that my method is the best, but it's just an alternative.

Also is that a snap-on dead blow style hammer I see? Excellent choice of tools, I have a 24 oz. ball peen one and I love it, expensive but worth it.

dude that mileage on his ORIGINAL motor is good, in my opinion. i have riden with eric and that motor was never babied, he pushed that thing to the max.


he was just sitting at a light and it died, when he cranked it back up he heard a loud ting and then only one rotor was firing. just dumb luck i guess.

Well I didnt push it to the max all the time, gotta get good gas milage somehow. usually shifted at 3000 rpm. I maintianed it well. changed the oil before 3000 miles. I think the timming was too advanced at idle because I was getting misfire at low rpm. I Cant sure because i never got a timming light on it. I didnt put alot of miles on it since i got it at 95,000 almost 2 years ago.

Anyways alot of the parts will be forsale soon. Upper/Lower intakes, fuel rail, water pump, air control solenoids (rats nest). everything is in good working order and organized.

I didn't mean Arockrx7 didn't take care of the car, but I think stock 12As should last much longer than that. Now I see he got it when it had 95k on it already, so who knows what its history is. Negligent previous owner, overheated, sat around for years, etc.

Dude. Just looking at the pics. That thing was running way lean before she popped. If you look in the front exhaust port, see how white it is in there. So, you going to keep the FI, or say screw it and go carbed? Keep us posted on how things go.

yeah sam your right. it does look very lean. I wish I had the chance to put a 5 gas analizer on it. Now I know better. I am researching the megasquirt II v3 and think I hope to set that up soon.

ill post up the forsale thread here. I have a bunch of perfectly good parts that I plan on cleaning and including the mounting hardware and all. keep a look out.

So..........you getting a S4 or S5? Either or, I think you'll be happy if you decide to go turbo! You still planning on doing a rack and pinion? That thing is going to be one sick puppy!

well if you help me out mocking up a mustang II or some other type of rack and pinion steering box then you can have dibs on the powersteering box. I am talking to a guy with a S4 but he isnt quick on the replies to the PMs. I want to have a motor next month.

I picked up a Taurus electric fan today for $15 at the "Pull-A-Part."
