Hey everyone, just wanted to query something. One day my RX*, it started puffing white smoke for a few minutes, then stopped. Since then, I’ve been cautious about its condition. I replaced the plugs, wires, and coil pack—all NGK parts.

I live in a remote area without access to a rotary compression tester, but I managed to use a standard compression tester, which showed 30 psi across all faces of the front rotor. Shortly after, I noticed the oil started draining much faster than usual, followed by hot start issues. After confirming that everything else was functioning properly, I decided it was time for a rebuild.

Yesterday, I pulled the engine myself, but now I’m unsure what to inspect in terms of seals. While I can follow instructions, I’m not confident in identifying whether a specific seal is damaged or needs replacement. I should be able to strip down the engine block on the weekend.

Any advice or pointers on what to look for during this process would be greatly appreciated!

 

replace every seal. the big concern will be the "hard" parts, housings, irons, rotors, e shaft

 

I am assuming for the hard parts its looking for warping , chipping , scratches and if I've spun a bearing?

 

Measure everything that is required. Mostly covered in the various old rotary rebuild videos from Mazdatrix and such and also mostly covered in the FSM. NONE of the youtube videos cover the hard work of measuring everything cause it is boring tedious work. Irons surprisingly wear out for example.

 

Oh well damn, guess I will watch those . Any advice on removing the eshaft bolt ? Ive tried holding the flywheel and using a 405ft-lb impact wrench counter-clockwise but the sucker is NOT loosening .

 

heat wrench and hit it with your purse

 

Does it matter which purse? LV or CK both work?

 

Well played! Give it right back.

 

But of course, is there any other way? I tried doing it for multiple cycles of heat and hitting it with my impact but it didnt work. I am probably going to offer the nearby construction site drinks and asking them to use a cheater bar to break it loose

 

IME, Oftentimes impacts are not the right tool for the job. On something like that, you need to apply torque and leverage and keep up the pressure until it cracks loose.

Or find a stronger impact.

 

(First post here, by the way. Hello world!)
I was in a similar situation a couple days ago, doing my first engine teardown, eshaft bolt was also stuck on there. I got a friend over and what ended up working was blowtorching it for 2-3 minutes, then a 24in breaker bar with both the jack handle and its extension, with both of us pushing down as hard as possible. Probably about 5 feet of leverage, and maybe 200-ish pounds of downwards force.
188-216 lb-ft according to the manual...
