Well,
As the title states, I am starting my teardown and rebuild of my 86 N/A Sport. This will be engine only at first, possibly electrical upgrades as needed. (I have to use her as a DD for about a year so no go fast mods at this time) I am tearing the motor down because it burns coolant. (busted seal possibly bad housing....) Although it runs and drives fine now, I do not wish to destroy a good engine. There is just no excuse for doing something like that! I am sure I will run into a few snags and snafu ordeals along the way so, check back often

PICTURES to follow in a few hours.

Thanks and wish me luck....
(First rotary rebuild but, been working on engines for over 10 years now...)

Cool. Keep us updated with pics! Don't forget the pics!

 

good luck, remember to pray to the rotary gods before you begin

 

Have fun! What part of Dallas do you live in?

 

OOPS! Forgot the pics! Sorry fellas! I'll get em up tonight! (at work now)...

Live real close to the DFW airport. (like, i see the planes fly over.. LOL)
I'll get the pics up asap!
STATUS:
Hood removed
MAF / Air filter box removed.
Radiator removed.
Battery removed (I will be needing a new battery tray ... got angry at mine and ripped it out, thats ok tho, I'll make a new one...)
-I got angry because the bolts all had been stripped by previous owner...

91k on the chassis and motor, all origional.
Interior gutted (no carpet, no trim, nada, just 2 seats and a dash with door panels)

removing wiring harness and such tonight, will be inspecting the entire engine bay harness for any brittle wires or cracked insulation around the wires etc and replacing anything as needed.

Again sorry about the pics! But I promise ill have them up here tonight!
Oh yeah, already sent up a prayer to the rotary gods in the form of:
Burning some gas on the ground and chanting:
Please don't let me F$*k this up!!!

clean looking car! let me be the first to say the obvious: get a shroud around your radiator fan!
cheers & goodluck

 

When i got the car the previous owner removed the fan shroud...
I just took the fan and fan clutch off and installed an E-Fan

its out now because.... I'm doing my rebuild but yep got the fan covered

 

Got the UIM off and apart and ewwwww... Coolant gunk on the back of the throttle body, inside the UIM (only a light film of it)... How nasty! I will be putting up the pics of that tonight (check back after 6pm C.S.T.) then I will be moving forward to complete removal of the wiring harness and air pump / exhaust.

Thanks for watching, and it's slow going but better to be slow and right, then fast and sloppy...

Do it once, Do it right, then if ya need some more excitement in your life yank yer girls bikini and use it for a polish rag...

BTW, since this is my first teardown, anyone know where to get replacement connectors for the wiring harness? If not there is an Aviation connector supply company here in town that I know the owner of that could fabricate the connectors, but, i'm sure ill have to buy bulk so don't really want to do that but if i have to ill probably sell my spares

Ok, so....
Here's what I've got done since last time
Wiring harness removed (engine bay)
All pulleys removed
air pump removed
water pump and housing removed
vac lines and fuel lines removed
etc.

Good News:
So far hardparts that I have removed look fine for re-use....

BAD News:
Most of the connectors on my wiring harness are so damn brittle they are breaking when removed...

All my fuel lines (soft lines... rubber) were so old and decayed and cracking, that I am suprised the previous owner hadn't burned this car to the ground... OMG it was nasty....

Injectors look a bit shakey, so I will send them out for cleaning / testing OR, maybe buy some new ones...

Lastly, on the lower fuel rail (closest to center of block on the top...) the contraption on the end of it looks warped???
(yes pics to follow im sorry...) I don't know what it is called but im searching for a picture of it now...


Thanks and yes I know, im slow with the pics but more coming....

Yeppers, I'm a slow bastard. Keep bouncing between the 88 vert and my 86 sport so lol, I got my hands full Got the engine out of the 86 Sport with this unusual method...
Stand in the engine bay, have buddy outside car in front, both grab motor, lift, set on truck tailgate...
hahaah, redneck as hell but lol, not very much space to work with in my garage at the house, which is why i took it to my shop. (no not my AUTO shop, actually, its got 2 unfinished airplanes in it... my pops obsession...)
Pics include, tranny, motor from all sides, etc. etc...
Starting the actual block teardown tomorrow after work so, more pics to follow tomorrow

enjoy and all comments graciously accepted!!!

 

=)

 

More bad news:
Apparently one of the transmission bolt holes (in the rear end iron) has been broken off, so I will be needing a new rear end piece.
(Terms are a bit off right now as I am quite seething mad at my idiot boss for being a dick... yes I am on lunch break...)

Will be starting the actual teardown of the block tonight and will have some more pics tomorrow, thanks for looking and please, if anyone sees something amiss... please point it out as I'm going

WOOT!

 

Ok, well here is what I did tonight, yeah, I know I am slow. =) pics
Questions!!!!!
Picture 1 is WHERE i pulled whats in picture 2 OUT OF.. Any ideas???
The rest is pics of the teardown as it is coming along over the next week (I work fulltime until 7pm so I don't have that much time in the evenings)
...
Thanks for the input in advance!!!!

P.S. Look at those heat spots on the flywheel!!!! OOoof!

Pulled the clutch off and looked at the disc... its stamped with "Exedy" =)
added bonus (I Had no clue what was in this car when i bought it)

 

Here ya go. Eat yer heart out....

 

What exactly is this odd sleeve thing here??? (1st pic) Thanks in advance....
Oh yeah, WTF size is that monster bolt on the flywheel/???? (Mine is damaged, apparently from someone trying to or possibly had done work to the motor before i got it.... )

THANKS!

 

EWWWW... look at all the nasty carbon on this!?!? *Pukes*

 

So those are pieces of your pilot bearing. the pilot bearing is in the end of the eccentric shaft where the input shaft of the tranny goes. idk how they break or why, but I've had one come out like that on me. My mechanic that changed my clutch told me that it came out in several pieces. Chances are there might be pieces in there "welded" to the inside of the eccentric shaft, I had this happen when I went to change my tranny. So best of luck to you thats the best input I can offer.

 

yeah, i figured pilot bearing since it was making that weird whine/vibration noise when out of gear etc. etc.

Thanks for the reply... Anyone know if those heatspots are bad enough to force me to get the flywheel resurfaced??
Thanks!

 

Umm, that's your 5/6th port sleeve. How familiar are you with how they operate? They are somewhat important.

 

I am not very informed on how these sleeves operate. What exactly is the point of the sleeves??? you can look in the fsm all you want, it just wont tell you why its there and what it does.... Please take the time to explain how the sleeves work and why they are important. Yes this is my first rotary rebuild. Diesel mechanic here so yeah, this is a bit of a new field to venture off into. i have faith... and LOTS of patience...

thanks!

 

The flywheel nut is 54MM, or 2-1/8". You can find the socket at sears, it's kind of pricey though.

"When i got the car the previous owner removed the fan shroud..."

Probably why you are burning coolant now. Who knows how long he had it off, but in the southern weather it probably overheated because of this (after prolonged use).

 

Thanks for the responses and input! headed to sears here in a bit to get that $30.00 socket that i need to get this damned nut off the back ... ugh... 2-1/8" ... what a monster! oh well. I will rip it apart and get back to you guys tonight with of course.. MORE pics! =) Thanks for the help and keep ya eyes peeled, who knows what else we will find when I get her apart....
