parad1mg Posted September 13, 2014 Share Posted September 13, 2014 So I finally had some free time to do my timing belt service and it was all smooth sailing till i had to remove the belt after removing the second smooth idler on the bottom end. I had both sides clamped down with the "bolt" method and a vice grip lightly holding the drivers side cams. As soon as i carefully removed the belt from the crankshaft gear and the idler right next to it, the drivers side cams decided to fling all of the things holding them in place and freely rotate. Good thing is that there's no damage whatsoever on the cams. Right now i still have the belt hanging loose on the remaining tensioner and passenger side cams. They are still lined up as well as the crankshaft. Can anybody give me an idea how to line them all up again? Link to comment Share on other sites More sharing options...
parad1mg Posted September 14, 2014 Author Share Posted September 14, 2014 As far as I can tell from the stuff found from googling this subject, I just rotate the top cam clockwise back to align the marks and the lower cam counter clockwise back to align with the top and side marks. Is that really all i need to do at this point? Link to comment Share on other sites More sharing options...
parad1mg Posted September 14, 2014 Author Share Posted September 14, 2014 re-watched meaty's videos and just followed that aligning the belt marks with the timing marks on the sprockets. Somebody correct me if that's not the right way to do it. Link to comment Share on other sites More sharing options...
Max Capacity Posted September 14, 2014 Share Posted September 14, 2014 I'm thinking CCW, just back it up. It's been a long time since I did mine. Those cams are under load because the pitons are midway in the cylinders.

parad1mg Posted September 15, 2014 Author Share Posted September 15, 2014 i rotated the upper cam CW and backed it a bit CCW when I was trying to align the belt marks. Same deal with the lower cam but CCW and backed it CW. After getting the 4 cams, crank and T-belt marks all lined up, I gave the crank shaft two rotations by hand and the timing marks all lined up perfectly. I rotated the crank several times by hand and the timing marks always line up after the second rotation. Does this mean I'm good to go? It was relatively easy to turn the crank over with the exception of the feel of the force of the valve springs at some point during the rotation.

Max Capacity Posted September 15, 2014 Share Posted September 15, 2014 Yes, you should be good. You can start it up, without the covers and drive belts just to be safe. I'd make sure there was coolant, if you want start it before the covers are on. Coolant so you don't get any sensors throwing a code. Bolt the crank pulley on. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
