I am working on my buddys 2000 contour with 4 banger. A week ago the timing belt broke. 120k on it!! He took into a shop and they replaced the belt, but not the tensioner, After they got it up and going they put it on there diag. equipment and said that #4 cylinder had a bent valve and was showing unburned gases exiting the cylinder.Car is drivable and runs ok, just a touch rough.
Hebrought it to me to check out. I run a compression test and all 4 cylinders show from 155 up to 167 psi ( bythe way, #4 had the second highest reading) . So I dont believe any valves are bent. So I thought I would double check the cam timing. I machined a tool at work to align the cams. Pulled the valve cover and sure enough. They were not even.
I proceed to bring #1 to tdc and pull the belt off the cams, then SNAP! the exhast cam has the variable timing on it I did not know about. (the haynes book never even mentioned it.)
My Question to you folks is How do I put everything back in proper time with the spring loaded exhaust cam?
Thanks
