Just received 2 housings on eBay. Filed a claim on eBay because packaging was complete **** and they were damaged (dented) in shipping. However, do you think these housings are reusable? They are dented on the edges of the housings.

 

you can actually see a lot of those small nicks in the pictures of the sold listing.. so it was just another careless seller. hopefully you got a chunk knocked off the asking price.

Oem Mazda rx-7 Rotor Housings rx7 13b engine rotary 93-95 turbo Fd3s 13b-REW | eBay


they could be used if none of the dings have a burr sticking in where the apex seal would grab it. so run a straight edge over the whole surface and see if it catches anything.

 

They are reusable , like he said ^

 

Got them for $468 USD shipped ($355 USD + shipping), straight edge will definitely catch some dings. I don't feel too comfortable buffing the dings, should I take them to a machine shop to have the dings buffed?

Should I insist on a full refund? That's my question. I wonder if I can use them in my engine. Bought some great apex seals and great everything, I don't really want to cut corners here.

Thanks for your advices!

 

Thanks for your opinion, I hope they are.

 

But I mean , dude just get your money back , the guy shipped like **** , it's his fault.
Nor you or your engine should suffer from it.

 

But if I bought 2 housings, that is because I wanted 2 housings. If there won't be any issue buffing the dents then I'll do it. Sure thing I want a refund, but if you guys tell me it is reusable, I can arrange a partial refund with him, instead of a full one.

 

for combustion surfaces get a thick straight edge and lay it over the chrome surface where the ding is and tap the straight edge with a hammer(narrow edge over the burr, perhaps something to protect the straight edge or use something sacrificial for this) until the burr goes away. if it protrudes into the coolant seal side after that then you can easily knock it off with a block sander. something like a stainless steel ruler usually would suffice.

the other method to fix them is with rotor housing resurfacing. i wouldn't recommend using a dremel.



dont know why you keep saying they were damaged in shipping, they clearly weren't. the seller just has never admitted to selling them like you actually pictured them. ie, stop protecting the seller beyond the obvious shotty packaging job they did on top of it all. how they managed to keep a 100% score is beyond me. i see why, because they only have 1 feedback score as a seller! amazes me how poorly some people treat these parts, considering they are not cheap.

 

Thanks but you know what's worth a straight edge, I don't wanna break it doing so (and that would happen for sure). Rotor housing resurfacing would also be pretty expensive.

Maybe you are right, that they were already damaged. However, the poor packing didn't help for sure. The picture showed how it was when I opened the box. I was expecting some damage when I saw the studs outside of the box so that's why I took as many pictures as I could. Oh well...

 

wow cant believe they shipped them out to you like that its easy to see and say its the seller fault for not packing them right but the marks/nicks/dents etc they have on them look like they were there already i dont think the damage they have were made by the shipping they would of had a bigeer damage then what they have, but they do look usable still

 

That's one of the worst packing jobs I have ever seen. Good luck getting something back from the seller and also on repairing the housings.

 

A few random thoughts:

Buying engine parts on ebay isn't too smart, and this is evidence of that.

You get what you pay for, for $175 per rotor housing you're basically getting someone else's junk.

I'd be pretty pissed paying over $100 for shipping and they arrive like that.

I would not use those in an FD build at all, but that's just me. If you want a shitty engine, make sure to use shitty parts

 

I couldn't believe there was one random towel there in that loose box. Maybe he knew something because he asked me to leave feedback just after he sent the item.




That's the problem, I bought expensive apex seals and expensive tools to make sure everything is within specs. I'm not cutting corners on this project, I want this engine to work perfectly. I never had any problem buying parts on eBay, for 11 years.

 

I agree on the shipping. That's inexcusable. How hard is it to toss in some padding of some kind and tape the box up properly?

Also, let's not forget the guy described them as in "OK condition". He nailed it. They're not pretty, but we've all seen uglier. He did overlook those burrs in his pics though.

Rotary Evolution definitely knows what he's talking about. If he says they're usable, I'd clean them up, try the straight edge trick and bolt 'em together.

 

When I'm sending stuff that is valuable and can be damaged, double-boxing is what I do. Parts inside the inner box with padding, and then padding between the 2 boxes.

A shipper has to try pretty hard to screw that up.

 

well, not necessarily. i sell my parts on ebay because it's still cheaper than trying to sell them here with a vendorship. it's rare i get any complaints even with how picky some people can be.

by your judgement Rich, can i come and pick up all your scrap parts? i'll build some engines for personal projects with them.

though i'm certainly not defending this ebay seller, he should have shown the damage in the pictures. being that these parts are not something you can just clean up and toss into an engine without some additional repairs involved.


OP, i didn't say a straight edge was the only tool necessary. a sacrificial metal ruler can also be used, or a metal bar about 6mm wide or so that is flat faced. you won't damage the chrome, just trying to tap lightly the ding below the wear surface. the tiny imperfections left won't affect the compression by any discernable amount and those housings look to be pretty decent still. however some of the FD builders are a bit **** about some things.

 

I wouldn't use those housings. This is one of the areas you do not want to skimp on. Not only do they look like they were damaged in shipping, they also look like they were mishandled and the one appears to have a gouge from a previous failure. I would return them.

 

2nd and 1st gen guys will re use almost anything.
3rd gen guys buy all new everything.
C'est la vie.

For what it's worth. I've seen much worse housing re-used.

Back in the day, 1st-gens never blew up - they just wore out to the point that there was so little compression they wouldn't start. But if you got it started, it still ran great. That usually was well beyond 150K miles.

 

Update: got a full refund from eBay this morning. Not sure if the seller wants them back (he would have to pay for shipping).

Thanks guys!

 

that's pretty surprising, unless the lazy turd didn't even bother to fight the claim. not like he should have, because he had to have known about the damage and tried to be ignorant about it.

 

And I also ordered 2 rotors on eBay. Received them yesterday. One of them is damaged, unrepairable. So I opened a case on eBay, again, just like the housings.

It is not the same seller.

 

Bro, you gotta start asking reputable vendors for parts. It's not like they're hard to find.

 

Or I could simply go to the dealership? Yeah sure. They are not hard to find.
