2007 Mazda CX-7 Touring 4dr SUV (2.3L 4cyl Turbo 6A)
On my 2007 cx7, Mazda warranty replaced vvt & timing chain that was grinding during start-up. While replacing, the mech found the intake cam way out of phase & called Mazda Canada tech line for approval to correct.
Mazda tech line asked for compression after vvt & timing chain replaced. Dealer Mech found #1 at 70/170; #2-40/100; #3-60/140; #4-30/80. Mazda Canada tech said this is ok and to send me home, happy that they replaced the timing chain. My Mazda Dealer told me they would recommend doing the required repairs but because I'm requesting warranty to cover it because it's a result of the timing chain. I called Mazda Canada & they told me to go back to my Service Manager to fix? Help!
