I am putting the heads back on a buddy's truck. When setting up the cam timing, the colored link of both chains should be at the same spot on the crank pulley, right? All the pictures I can find show the pass side chain mark. Nothing about the driverside chain. Anyone do both chains before. I've only done the pass side until now. My question is the link on both the front and rear sprocket at the crank should be in a line, colored link in front each other.

Good day,

All the modular motors are the same regardless of the size. Ford made it easy to set the timing on these motors as compared to the very complicated 4.0L SOHC V6. The crank should be at TDC. The key on the crank should be in the 10 to 11 o'clock position when looking at the front of the motor. The timing mark on the crank gear is at the exact 6 o'clock position for both chains. The easiest way to mark the chains (if they aren't already marked) is grab one link with your fingers and hold the chain in the air. The other mark is the opposite link at the other end of the chain... Put that link on the crank timing tooth and put the other link on the cam pulley timing mark, while keeping the chain on the right (stationary) guide rail taught. Install the tensioner arm after the chain is installed... Be aware the cam gear may want to turn if you have the roller followers installed while doing this... I recommend you ALWAYS take the rollers out until you are positive the timing is set up correctly to avoid valve damage... They can be pulled and installed with everything assembled!! All you need is a big screwdriver to pop them in and out of their spot... You can do this for both SOHC and DOHC modular motors... This also eliminates the need for special cam holding tools...

Okay, book is long enough...

Good luck and let us know the status...

Cheers!!

Thanks for the help. Just needed to know that both are at the six o'clock position at the crank. I did buy the crank holding tool. We needed to spin the engine over with the heads off. I do have the tool to take the rocker arms out too. I could see the darker links ok. I spun it over this morning and all ok. It had been a long day and my eyes were getting the best of me. 5am after working 60 hours this week and staying up late on friday getting it apart. Much appreciated for the input. I did put a head on a 4.0 SOHC once, never again. Come on engineers!
