    depends on your compressor, bendix the repair kit is about 15 bucks and 10 minutes to fix if it is the unloaders

    If you have an ISX you must replace the compressor cylinder head. What engine do you have? Do you know your engine serial number?

    Yep, if the unloaders are leaking, you will need to replace just the head of the compressor. The unloaders are not serviceable separately.
