Yea sure, but what happens if you just start romping the motor right off the bat. Those seals wont set the same as they would with a proper break in, right? your the RX-7
also should I port or not
Seeing as I am good buddies with the current owner of PFS and the guy who most likely built your engine I have some insight here. First off they have no reservations about getting a car on the dyno to tune them as soon as an engine they have built gets installed back in the car over at PFS.They really do not make a large emphasis on breaking in the engine. I think mostly because in all honesty ( and this is my opinion here) people make it out to be more important than it really is. I am not saying that you should not go easy on a motor that is fresh if that so suits you. However if you don't it most certainly would not be a definitive cause to a loss in comression. I think it would actually be extremely rare for something like that to happen.
The seals will seat in about the first five minutes of the engine running. That is generally about as broke in as it needs to be.
Aside from that I would would not make any assumptions as to what is wrong with the engine until you take it apart and have a look.

My car is maintained perfectly, everything done exactly how the manual states, oil changed 2k miles, spark plugs 5k miles. If you don't have something to say pertaining to the subject at hand, stfu. Go back to gen d if you want to talk sh*t.
Im trying to help you figure out what the problem really is so it doesnt hapen to your new engine also. Do you know how to read plugs? Thats usually a good indicator of how the engine was running.
I dont think a stock engine with 10k miles is just gonna drop its seals for any small reason.

It's called a rotary engine unfortunatly.
theyre not THAT unreliable. seriously. a brand new rebuilt motor dropping an apex seal at 10k? unless you were beating the **** out of it or some system failed and caused something bad internally, then it should be fine. I mean unless you just have horrible luck or something, or faulty internals.

The motor comp tested fine when I bought it. I don't be the car at all, Amp even told me that I don't drive it hard enough
I mean im sure its that motor, but you never know i guess. I'll post in this thread what happened when Ihor has the motor apart
oh kev kev im not sure if it is a apex seal or not, but it does have lowww compression on the front rotor. Funny thing is, the front rotors spark plugs are caked with soot, it was running really really rich at normal driving levels at least. The rear rotors plugs were brown/tan with no residue. Go figure, maybe I have an injector prob, but the new motor will be running new injectors.

no I haven't, nor have I tired the water cleaning or c foam. should I even bother? I guess its possible it could be from carbon build up, that would explain the terrible plugs. Should i even try new plugs too?

I know you said that you did compression test it, but it just seems odd that you would loose one face for no appearent reason. What happened that made you decided to compression test the engine?

car sounds different and drives differently not under boost, also the vac and idle randomly drops to being really low, like 12 g vacc and 700 idle, then goes back to normal 1000 idle and 18 gram vac. any electrical load makes the engine bog like crazy
