Twistedrx7 Posted December 15, 2008 Report Share Posted December 15, 2008 So about a year ago in november my car ended up on the chopping block since the engine decided to die on me. After a compression check the front bounced at 95 on all three faces. The rear however was 80 0 0. I ended up buying another engine and put that into my car. Well, i finally got some time to take it apart and found more damage than what i thought. I had thought maybe i just fractured a seal since i could see the each entire apex still on there through the exhaust http://i27.photobucket.com/albums/c168/twistedrx7/CIMG2946.jpg To my surprise this is what i came across. This is the Rear housing. http://i27.photobucket.com/albums/c168/twistedrx7/CIMG2949.jpg http://i27.photobucket.com/albums/c168/twistedrx7/CIMG2950.jpg The Rear Rotor http://i27.photobucket.com/albums/c168/twistedrx7/CIMG2951.jpg http://i27.photobucket.com/albums/c168/twistedrx7/CIMG2953.jpg http://i27.photobucket.com/albums/c168/twistedrx7/CIMG2955.jpg The Apex seal that did all this damage http://i27.photobucket.com/albums/c168/twistedrx7/CIMG2956.jpg Quote Link to comment Share on other sites More sharing options...

Crossle Posted December 15, 2008 Report Share Posted December 15, 2008 Cool pictures, I find it interesting. Apparently not everyone feels the same..... Educate me a little..... Is there a whole machining process to fix that? Or do you just have to get new rotors and housings? If that was the case is it better just buy a whole new motor? I guess this is a stupid question to those who know a lot about these motors, but I'm curious. Quote Link to comment Share on other sites More sharing options...

Twistedrx7 Posted December 15, 2008 Author Report Share Posted December 15, 2008 This is my old engine i have another small bridge port in the car right now. You cannot just throw in a set of rotors at all, they need to be the same weight rotors. Rotor housings need to within spec, or just buy a new one. It all depends if the intermediate housing are alright and the end housing if the engine is better to scrap to sell parts or rebuild. It is not too hard to find good used parts.

Twistedrx7 Posted December 15, 2008 Author Report Share Posted December 15, 2008 The engine only had about 24,000 miles on it. Quote Link to comment Share on other sites More sharing options...

500HP RX-7 Posted December 15, 2008 Report Share Posted December 15, 2008 That is normal apex seal damage from the shitty Mazda seals. Switch to Aviation seals and you will never have that problem again. Quote Link to comment Share on other sites More sharing options...
Scotty2Hotty Posted December 15, 2008 Report Share Posted December 15, 2008 You didn't buy the cooler ranch doritos. That's the problem. Quote Link to comment Share on other sites More sharing options...
Smokey Posted December 15, 2008 Report Share Posted December 15, 2008 sucks. Did you ever figure out what caused the failure? I'd say the housing and rotors are nice paperweights now. Quote Link to comment Share on other sites More sharing options...
Lustalbert Posted December 15, 2008 Report Share Posted December 15, 2008 It has been a while since i have seen a rotaty owner take a good beating on here for thier facination with the alien technology. So that is what happens when the tasty powder coating comes off. Quote Link to comment Share on other sites More sharing options...

Twistedrx7 Posted December 16, 2008 Author Report Share Posted December 16, 2008 Nope any scratches that are deep like that are not able to be saved. A new housing is about 600 bucks and used for about 2 -400 Quote Link to comment Share on other sites More sharing options...
