Hi, does anyone know how to tell the difference between the intake and exhaust camshafts? I might have, possibly, accidentally mixed up which cam went where as I was cleaning the head on my 850 turbo
Thanks for your time!!

 

When the cams are timed, the exhaust valve on #1 is going to open sooner than the intake on #1.

 

Look on the end of the cams. Not the sprocket side but the rotor/cam position switch side. There will be a distinct 'E' or 'I' on them. Last letter.


Exhaust




Intake

 

If you have your head apart, and you'd like to get a little more low end torque and faster launch, you should consider installing a set of NA cams. They will give you more low end torque and add about 11 HP to your car.

 

...and those pictured are N/A cams.

 

Thanks you guys, been cleaning the head and just checked back. I felt like I was up a creek but now I am back on track!! Thanks again..
