I just bought a timing chain with zero degree, 4 ret, 4 adv. I set the crank sprocket at zero deg. I was told the cam(xe-256h) was retard 4 degrees from the manufacturer ? Now i'm confuse where to set the crank sprocket ? 4 advance ?
Set the crankshaft sprocket at 0 degree. Factory crankshaft sprocket is only one place you can set and is 4 deg retard for emission thing. Aftermarket timing chain set can be adjust 4 ret, 0(straight up) or 4 adv.
Ok, i understand your point grclarck351. Look,in my first post, why i want to set up 4 adv. Where is best to set it on crank to have max hp and torque ? thanks
i'd install the timing set at 0 and check the cam position with a degree wheel to verify that it's where Comp says. short of that, just install it at 0
