is there a way to restore compression? my 87 rx7 lost compression in the rear rotor so ow it's just sitting.

 

87 na... 87 Turbo? Did it have compression and suddenly lost it, or has the engine been sitting, not running for awhile? If it had been running and lost it suddenly, then you are in for a rebuild.

More details on the situation!

 

its a n/a and it lost compression after driving it for a couple months after buying it

 

How do you know it has lost compression, ie how are you testing the compression? What numbers are you getting for compression?

 

if you are 100% sure it lost compression and you have tested with a compression checker, then you know what you must do.

unplug the rear injectors, and drive it like that. might get you able to drive it around. some people have driven to California and back from the east coast on a blown rotor and not known it.

the damage wont continue to happen. once its been done, its been done, so no more can happen.

or just rebuild the thing

 

rebuild the motor is the answer

Time for a rebuild!
