Welcome to the forum and the MX3 community.
Have you tried contacting your local Mazda parts dealer? They should be able to identify the bolt size.
Secondly it might be worth a look on the online manual at mx3.com, there might be a bolt size chart somewhere in there.
Found gas tank on e-bay for super cheap. Decided to make this a practice project. When spring comes Ill try to fix the rust and replace needed parts by myself. If I don't manage then I'll just scrap it.
If someone else needs it, should be the right part:
Im based in Kent and i 2 MX3 1.8 V6.
I currently drive one as a daily car and have had no problems with it however the other was my daily car until i had the same problem as yourself, smoke from the exhaust.
Make sure that you have diagnosed the correct fault (Valve stem seals) as i thought that was the fault that i had on mine.
It turns out that i had a bent piston rod on cylinder 1
The first thing that i would do is to do a compression test
There is a lot of work involved in doing the stem seals as you will need to remove the heads from the engine to be able to get to them.
I would also recommend looking at the valve stem guides and the valves plus valve seats while you have it all apart.
While you are looking into this amount of work you should be able to find a workshop manual online that you can download or you can get a Chilton manual from the bay of e.
The Chilton is ok as a guide however the workshop manual will provide more details.
With regards to the bumper i would possibly say that the bay of e would be a good starting place for a replacement however you would also have the option to change the bumper for a different look should you wish to.
The central locking system could be something simple like a fuse or the bar on the door lock has a broken clip however it could also be the central locking system itself or even worst it could be a wiring fault which can takes weeks/months to go through if you don't know where you are looking.
The sunroof is an easy one to do, open the sunroof and remove to liner inside.
You will then get access to the nuts that hold it onto the frame, remove these and it will just come off so that you can repair/re-paint it.
I don't come on here that often however if i do see you post when im on here i will do my best to help you out.
@ccag2762 Not sure how to view the pictures as they do not seem to appear, also your comment on how much you got offered just show £ sign but no price.
these cars are very misunderstood as most folk do not know they exist & when they see one they assume it to be more modern - not realising how rare they are now.
Check out the project pages to see what people have been up to!
There are so few of these out there now, many are off the road, like mine.. for now :)
As Ricco mentioned probestore does stock some items but a few people have had mixed results from them, I think this is in part due to the reduced availability of parts for our cars.
I've had pretty good success from my local Mazda dealer, and not all of the parts from them are over priced lol
Welcome to the forums
Must admit it does sit a bit high could do with lowering a tad,only thing is it had new shocks discs n pads for last mot couple months back just before I bought it,be a shame to change um when there brand new,l shall be keeping it for near future so it's something I can consider,ya just think with that engine it would have great potential of been able to be tuned up a bit
Hey everyone, just got my Mx-3 back on the road, absolutely love the thing!
I have another one sat in my garden gathering dust, simply because its an Auto so its my spare parts car. If any one is in need of anything that i'm able to remove let me know!
There hasn't been a club meet for a while and I'm not sure how much interest one would generate now because the forum has become somewhat quite over the last year. I am also a member of club323 and they have regular meets so they would be worth a try and some of the people on that forum know alot about mx3's
