they look fine to me... How many miles are on them? Also, is there any pitting that you can (to beat a dead horse) catch a fingernail in?

What rebuild kit parts did you choose to go with?

good work, dude.

felixwankel88

33K???? 133K Maybe....... BUt they look useable... just take a scotch brite to those areas with a bit of carbon on them,,, wanna get that residue off.

felixwankel88

now i was told the housings has 33K but they prob dont

RETed

Any weird grooves?
There looks like some weird grooving right above the exhaust port, but photos can be deceiving...

I'd call them an 8 - 9 out of 10.
Those are some really nice housings.
33k sounds about right.
NA, right?
They can't have more than 50k miles on them.
86 - 88 NA, right?

i just went and felt the exhaust port area and they feel smooth, and yes they are 86-88 housings...

felixwankel88

o yeah they are na too

Those are some of the cleanest Zenki NA housings I've ever seen.
Where did you find this motor???

That milky white surface is the surface coating that Mazda puts on brand new housings.
Really worn housings get all shiny.
The milky white coating surface is actually better!

I wouldn't worry about the chatter marks.
It looks like the engine wasn't even broken in yet!

DOH! I buffed mine till they were shiny!!
Good thing I didnt use them in a rebiuld

felixwankel88

well i got the engine in a parts car, that was overheated and the coolenet seals melted... i waz told it was rebuilt with new housing.. ive been told two stories about the engine in the car ive herd 9k miles and ive herd 33k miles... well they should make good compression rite??

BGH

Be sure to lay the housings down and
put a straight edge across the housings
to check for ANY warpage.

Yes, those are about 9/10 housings...just the beginnings of chrome flaking. Those are perfect for any rebuild. You usually don't have housings in near that condition available.

so if you scotch brite them untill they are shiny will it just cause slighty faster apex seal wear? or can you get them recoated in anyway? sorry to jack the thred

I wouldnt tamper with the rotorhousing surface at all.

Tofuball

Wow, those rotor coatings cost less then a brand new rotor housing.

I wonder . . .

sorry 4 the highjack too!

i also want to rebuild my engine!

i have know 168.000 km on the engine, she runs fine, but i don't want do risk a broken apex and a scratched housing!
so i want to do a rebuild on it in the next time... you think the housings will be ok? (enough oil everytime, never overheated, never pushed cold etc.)

iTrader: (4)

Thats how my housings looked! I have 15K now since the rebuild. I would definitely use it.

Tofuball

Does anyone have experience with those coatings? Are they for race use only (IE: they flake off after a while, or reduce apex seal life, or something else?)

RETed

Who recommended to do that?
Just get rid of all the dark crud deposits using a strong cleaner and don't be scratching the surfaces up!

well this is how much carbon came off after 3 mins of orange cleaner and a paper towel
