FC3S Murray's never ending build.

[FC3S Murray]

Which apex seals where used? The chatter marks look pretty bad.

Standard 2mm Mazda???

The irons and the ports, the intermediate ports looks good.... as for the cutting tool hits...... I would take a fresh side seal, or the back of a used one and move it over in every single direction and see if it catches. If it doesn't, which I doubt it will becuase the engine has been run, I wouldn't worry tooooooooo much about them. Is it ideal? No. Liveable? Yes.

I am still a little reluctant if I want to use this intermediate iron. I do not want to fork out that much cash for lapping on the front and intermediate(new rear on is good just needs port). I don't know, my last motor I took apart had even a bigger lip in it and it had 105 compression all around. I would most likely find a ported intermediate that is within spec...themn I won't have to invest the time into waiting on the lapping and cleaing the coolant jackets.

Remember my goal is August. With Family and work that is flying.

Side seals - I would replace those along with the springs. The 86-95 seals are all the same. The S6 springs are stiffer though, or so I have been told. Makes sense as they are a different part number. & be careful clearancing them. The difference between good and no good is .1MM and I set all mine to between .05-.08mm. My tip would be to buy 14 or 15 just in case. I broke one grinding it

I planned on doing new side seals. Springs too. QUESTION, what apex seal springs do I go with when I use the RA Super Seals?

Judging my the rest of your car, the only thing that falls into this category is what you just pulled apart.

Thanks man. I hope this goes well.

BTW good luck with the dyno session tomorrow. I wish for only lots of HP and very few problems. I will shoot you a line if I have any ques's.

I haven't slept in 40 hours so I'm a little loopy but they look like the old style of aviation seals.

They were associated with chatter marks, HOWEVER, so are other things. I found out today actually that something to really look into would be the correct counterweights/rotor weights used.

Yeah I hear ya on the cash and the timeframe but remember (generally) Rushing takes longer and cheap costs more in the long run.

Rotary Aviation Race Springs. I believe they are $72/set

Take your time and I'm sure it will... as for the dyno, we didn't even get passed the pre-dyno compression test Details in my thread so as not to jack yours. Shoot me a line if you have some questions and you also have a PM.
