I have a 2005 Mazda6 that I bought for my daughters first car. It has 180,000 miles on it. When I got it it leaked oil very bad out of the cam seal where it exits the back of the head for the water pump pulley. I have replaced that seal and the valve cover seals and VVT Solenoid seals. When I did the plugs and valve cover seals, I noticed a significant amount of oil in the intake runners. I replaced the PCV valve hoping that was the cause of the oil but the car still misses a lot when you drive it. I am getting ready to take it apart again to try to solve the miss it has and was wondering if I should replace the coils. I figure if they are the originals they have well outlived their lifespan. I am also going to check for oil in the intake runners and probably change the PCV valve again.
Has anyone had similar issues with their car? Any issues with the coils? Or, any suggestions on what to do to solve the bad miss it has right now?
Thanks!
Jeff
