hello i have a cx7 2.3 turbo and ran into the same problem with the vvt
actuator. installed it no problem but now i have no spark? how did you ever
figure this out?
I have 2.3 in my Mazda 6, broke some valves, never found out the cause, got
the head shaved and new valves put in, put everything back together and
broke more valves then damaged piston heads a little, the head is chipped
now so I scrapped that. Tensioner was 8 teeth out so i bought new one and a
chain, now just have to buy another head and try again with new stuff!
ill pay you to help me with mine haha
