Ok guys.. As I said, I would be checking the E cams in my motor.
Quick facts: 2.4 Tpistons, .010 taken off the OE spec heads, using .25 base Gasket, E cams. The bottom end has not been touched or opened by me.
So, I was told the valve overlap on these is 3-3.3 mm or .118- .130 in
and to set them to the 3.3 for maximum performance.
I was able to dial the driver side one to Exactly .130 and the pas to .126 after turning the motor over Several times. I was very pleased!Now for checking the Clearance. Its my understanding as mentioned that 1mm on the Intake and 1.5 on the Exhaust would be "plenty of clearance"
I could, with NO problems whatsover, set the Intake to .75 and Exhaust to 1.25 and it Worked SMOOTH as Silk.
I next turned the Intake to the recommended 1mm and exhaust to 1.5 bumped the crank and everything worked . SO, I proceeded to Turn the motor over and Did NOT seem to have any problems or binding.
I turned the motor over several times in a smooth manner. The only thing I heard at a specific point while turning was a Slight "tick" sound.. after examining it closely It appeared to be when a Valve would be Touching Back at its Seat on the Head. To me it appeard to be ok.
SO, I proceeded on, looking for an Interference issue which seemed to be when I turned the Intake Between 1.125 and 1.25 and Exhaust to 1.625 and 1.75.. Basically just shy of 1.25 and 1.75.
I did this procedure by first only turning the Intakes, then backing them off.. Then turning in the Exhaust and checking . and lastly Turning them All in Equal distances in a step procedure paying Close attention to any Sounds/ Binding and these were my results.
What are your Expert opinions on this? Will It be enough Clearance Once the Engine warms up and the Cylinders expand and with all other factors considered. ...
If needed I could Re-calibrate the Cams to the Lower side of the spectrum at the 3mm or .118 which would allow for a little more clearance.
