If you had sent it to me for rebuild like you were supposed to, you would've gotten the same parts back and thus your plate would have been already installed for you. :spank:

just a quick question,
would a worn apex seals be the cause of rough idle?

Yes, apex seals, side seals, carbon build up making seals sticky, vacuum leak, bad motor mounts, etc etc.

I wouldn't know unless I take apart the engine

Well you can check for vacuum leaks....

Nothing is wrong with your approach but I agree with Rotary Resurrection on this topic: There are things that are critical to be torqued with an instrument and there are things that a veteran builder can do with his hands (Just not critical, combined with feel and experience). The non mechanically inclined should not be touching anything on their own engine.

I'm sure you do excellent work though.

Paul.

All of this is absolutely true! One more note (Sorry for thread jacking), people think they need to torque to the upper end of a range. This is not the case at all. Tighter does not equal better.

I shall go back where I belong now :).

Note some more revisions I edited in.

RX8 Complete engine teardown to bare short block how to
 

Hi mate great read do you have the pdf file to this please

Can someone tell me what the part is that sits in the block in front of the dipstick that is soaked in oil

New here .I really liked the whole thing. It helps me understand my 8 and the way you presented it is out standing. Thank you. I will be looking at your photos a lot .

Why not both of them lol.

Lots of pictures...
 

Just took my engine apart and put it back together using these instructions. Spot-on for the order to do stuff.

Only addition I would make is to take lots of pictures of your own engine while taking it apart. The pictures RR has above are great to identify parts, but I ended up backtracking several times to get hoses routed properly on reassembly. My own pictures were much better for figuring out whether Hose A went above or below Part B.

And has been mentioned many times, make sure to label the end of every hose and connector, or you will be guessing!

I attached a drawing from Mazda on where the various gaskets go. Most are pretty obvious.

As a side note, I listened closely to RR's "I don't know how everyone breaks their OMP", and ended up breaking mine anyway. Happened when I was cleaning it before putting it back on. I was paying so much attention to being careful of the long oil lines attached to it that I ended up dropping the pump body right on the position sensor and broke the electrical connector off. Doh! :shocking:

Does anyone know when you buy a reman engine from the Mazda dealership, will that engine come with the pressed in removable coolant/oil pipes that's in the iron already installed on it or will you have to re-use the old one? Also will a new engine come with new studs on it or no?


Pic for reference of what I mean, the small straight pipe that I believe is the dipstick tube?, the angled one, and the black odd shaped one

It seems that this engine from mazmart has the pipes and studs already installed but what about a dealership paid engine?

I got one from the dealer recently. Came with the coolant pipes and studs in it.

Almost done with the re-assembly for an s2. Some slight differences around the OMPs - the order is a bit different. Was not too bad to figure out, more that I was paranoid of remembering how to put it back together, but those and the harness went back without much issue. Re-routing the TB coolant hoses was a pain though. I took pics of most things and it was very necessary 8 weeks on... but no pics of the TB coolant hose routing and they go right through the middle of everything. I have it figured out now, just took a few redo's.

So, I'll echo what others have said - take a pic of eveything you remove, including the routing. Makes it so much easier to piece back together. Also, a piece of cardboard to poke all the bolts into, with a note by each to list the bolts and pieces in the order you took them off is very useful, along with labelled bags for the nuts.

Have to say, MASSIVE thanks for the DIY. Hopefully I'll have the engine back in by this time tomorrow :)

Hi. Thanks to DIY like this and the other on how to remove the engine, I have been able to remove and tear down my engine. Now I'm ready to begin put everything back in place, and a doubt arises.


Does it make any difference which of the three rotor corners of the rotor is used to orientate the rotor? I can't find guidelines regarding this. To clear up, I took care to identify front/rear rotors and which face goes toward front and toward rear. Also from the videos I have take a look and the Mazda Engine Workshop manual, I'm clear the rotors are installed one with one corner pointing to one direction and the other to the opposite (usually down and up), but not sure if it can be any rotor corner. Does it make any difference? The rotors are the original one so there are no marks other than the codes for the rotor and the side seals. Only there is a tab in each rotor on the side opposed to where it has the gear. Does this tab means something?


I searched here, checked various reference videos and the workshop manual, but can't clarify the issue.

That was really a great write up on so many levels, thank you for posting it:).

RR I just used this guide to strip the engine I took out last weekend with your other guide - thanks buddy, it's been a big help

I'm sorry, I didn't know where to ask this, and I do not have permission to start my own thread so I figured I'd ask on the thread I followed to tear down my engine.

I have rebuilt the engine, but still can't seem to figure out where one hose goes on the engine. It can sort of be a mess if you didn't label right because you didn't expect to be rebuilding an engine for a year. Anyway, this is the part that i can't figure out the location.

Looks like the hard line for the LIM, your missing another section of hose.

Travis

OMG i now remember seeing that other piece of hose and not thinking anything of it. Thanks so much!

What happened to all the pictures in this thread?!

They were all hot-linked rather than uploaded onto the forum. Now the links are dead. Unfortunately it’s an all too common Internet forum mistake.
