lost of compression
 

so i took my 04 mazda to go get fixed and showed up as a misfire on cylinder 1... fixed the check engine light but whenever i accelerated the light would come back my mechanic says that there isnt enough compression in my engine and also that water was leaking into the engine.. PLZ HELP ME what can it be is it the rotor or the housing???

If it's low compression then it needs a rebuild, no matter what it is.

hmm how much am i looking to spend
