i have low compression on one of my rotors as well... im having the engine taken out and the apex seals looked at and possibly replaced.

The engine needs a rebuild. If there are 2 chambers with low compression, then its a bad apex seal. If its only 1 chamber with bac compression, its a bad side seal. either way it needs a rebuild. Thats the only way to replace the bad seal.

it just got rebuilt and ported right before i got it. how mch is this gonna cost if i have someone doit.

nobody knows how much it would be to get the apex seals replaced

if it was just rebuilt and ported then a rebuild would consist of apex seals. Bad compression on one or both doesnt point out what the problem is. How low is compression: how did you test, was it cold or hot.
