Cam timing

[fohengr]

I am in the process of changing the cam chains and tensioners on my 95 3.2 i bought the car as is with a loud knock in the top end found a bad rear tensioner and the front one was worn pretty bad as well the guy i got it from made an attempt at the repair with no success the cam gears and chains were removed and the cams rotated and then just put back how can i be sure that all of the cams are in time when I install the new parts and how do I get it all right. Thanks Keith

Do you have a Helms manual by any chance? There is a special tool that you slip over the hex part of the camshafts that keep the two cams (intake and exhaust) lined up while you get the cams put back down in the cam towers.

Once the intake is timed to the exhaust on each bank separately, then you tie the two banks to the crank with the belt at the front of the motor.

Autozone has the procedure on their web site. It looks like it's identical to the procedure in my Ford shop manual.

Tom, how necessary is that tool for positioning the cams? Where can you find it?

Milt, It's not an absolute must, it just makes it easier. The cams, when timed properly are on the rising or trailing edges of some of the lobes, so they don't want to stay put, they want to rotate off the lobes. That tool comes in the Rotunda kit.

You could use two crescent wrenches on the hex shafts and somehow clamp them together. I did that on a Toyota once.
