causes of no compression

what are the possible causes for an engine to have no compression on one (in this case its the front) rotor? im looking for least costly repair first. hahaha

Multiple blown apex seals. At best a rebuild is needed, then you have to worry about what the seals did to the housings when they flew around in there.

Sure theres a slight possiblity that theyre just stuck and can be unstuck with the water or another trick but I highly doubt that'll cause absolute zero compression.

stuck or broken apex seals, a blown coolant seal would not cause no compression.
