Overheated motor rebuild.
 

so i ended up overheating my car when my radiator cracked and now coolant is sneaking into the oil. from what ive been reading most people that do this end up replacing the o-rings. mazdatrix sells a kit and just wanted to make sure i buy the correct one Cart Price Check Part:10-S60A-N3Z1

what else do you guys think i may need?

is it neccerssary to buy this too or can i go with out it?Cart Price Check Part:10-S50C-N3Z3

thanks in advance hope all is well with you guys :beer05:

Probably need all other engine related gasket.
Might as well replace the apex seals and stuffs since you are gonna rebuilt the motor anyway.
Good luck~

You need to spec everything and rebuild the engine. But since you don't seem to know much about rotaries you are better off just using this engine as a core and getting a reman from Mazda.

engine only has 50k on it really didnt wanna take it that far since im gonna do it myself. why do you think i need to rebuild the whole engine? have you done this before?

It's pretty obvious....even just replacing the seals, you need to remove the housing....yes, that means taking the motor apart, which means reassemble the motor....and that equal rebuild.
Your motor is gone, period.

when you take an engine apart theirs gaskets and seals that cannot be used again. besides replacing the o-rings what else is needed.

i asked you if you had done it before. why am i gonna spent $1000+ on things the engine doesnt need. i perfectly aware i have to take it apart and put it back together.

There are only 8 major parts to the entire engine. You will have to disassemble the engine entirely to change anything. You would be asking for lots of trouble if you were to reassemble it without replacing all of the little bits.

Even if you were to replace all the little stuff, you still probably need to have the irons lapped and possibly new housings as well due to the coolant eating away at the housings and/or housing warp.

This isn't a piston engine where you can replace one thing and get away with it.

or did you think i thought the o-rings were on the outside of the engine? lol come on now

According to this post:

...yes, you are wondering why you have to rebuild the whole engine. Disassembling the whole thing means rebuilding the whole thing. :scratchhe

i was asking if any parts end up going to shit when takin these engines apart so i can replace them. why replace anything that isnt broken. now thats just asking for trouble.

i use to be a honda guy back in the day. rebuild a d16y and turbocharged that little thing after blowing the head

This isn't a piston engine. If you think you can take your piston rebuilding knowledge and carry it over to a rotary, then well, have fun.

10,000 miles on your "rebuilt" engine will be a miracle. I just pray you don't foist it off onto someone as a a good engine.



PS: Asking for advice from people that know, and then rejecting that advice because you already know better isn't really going to get you far around here.

As pointed out to you earlier replacing anything internally means rebuild. Given that this engine only has a few parts, doing it correctly means replacing them all. Reading your posts however I say, buy what you think you need, slap it back together and let us know how that works out for you.

this is why i rather have it rebuild then just buy another one at a junkyard. how do i know the next one i buy isnt blown? or damaged? compression tests do tell you everyyhing.

If you are going to have it rebuilt, then you won't need to research the rebuild kits ahead of time because any reputable rebuilder will source that for you and charge you accordingly.

Hunting for rebuild kits implies that you are rebuilding it yourself, or you have a shady rebuilder.

be real man who has money to buy a new enigne from mazda lol come on now

See, you are just proving how much you don't know.

The cheapest rebuilt engine available will be a Mazda reman from a dealer. $2,001 (list price). But it's the cheapest for a reason, the quality is completely hit or miss and you could buy a DOA.

Paying a reputable rebuilder is going to cost you more. How much more depends on what needs to be replaced and anything else you add on, like porting work.


PS: You are telling that to the WRONG person...

A reman from Mazda is $2,000.00ish (as low as $1850.00, as high as $2400.00 depending on the dealer markup). It will cost you that at least to do it yourself and I doubt you have the tools or the ability to do it yourself and that is if your hard parts are reusable, which is doubtful considering you overheated it. If you need even one new housing that will cost you $700.00.

so now youre taking back your recommendation lol come on now

Um....no?


I have no idea what you are reading.

Now, I REALLY wanna know how your "rebuilt" engine runs.

you said buy a new one from mazda. then said theirs a 50 percent chance it might be a POS. come on now.

Not only did I not say it was "50 percent" (I didn't give a percentage actually), but we are saying that for the price, buying a reman from Mazda will have a better chance of getting a decent engine than rebuilding it yourself. Rebuilding it yourself will have a nearly zero chance of a decent engine, getting one from Mazda will be a better chance than that.

And those two choices will cost about the same, with the reman possibly being cheaper.

this means getting a good engine from mazda is like flipping a coin. thats what hit or miss means. come on now

Yes, that is exactly what we are telling you.

Rebuilding it yourself without replacing everything properly, relapping the irons, etc... is like calling heads and deliberately putting the coin on tails.


If you want to be sure of a good engine, go to a reputable rebuilder. There is no cheap way to rebuild these engines right. NONE. End of story.
