timing 911 need help asap
So I got my timing set from snap on today everything was goin fine until I went to get tdc using the timing pin but the timing pin was missing not existant I searched everywhere under the pump and by the powersterring pump the retainer is ther but the deal you push in is gone. My question is is how do you find tdc without it I have the whole front of my truck apart cus I'm doin the kdp and the drive cover gasket since I had a leak. Can someone who's done there own timing give me a call and tell me what I need to do. My number is 5302827522 I have to get this done tonight
Thanks
Dave

actually in your description when the exhaust valve just starts to move your at BDC and the piston is getting ready to come up on the engines exhaust stroke... AFTER the exhaust valve starts to come up roll the truck over slowly; right before the exhaust valve closes the intake rocker will start to open; this is when that cylinder is on over lap. a small ammount of charge air is allowed to creep into the cylinder prior to full lift and exhaust valve closure to evacuate the cylinder. at this time the companion cylinder will be on TDC compression stroke. cyl 1 being cyl 6's "companion"

I would roll the motor untill both the intake and exhaust valves are loose. that means your on the compression stroke for that cylender. pull the #1 injector and use a screwdriver to find when the piston comes all the way up. roll the motor slowly till the piston just begins to fall and mark the damper, roll the motor the other way till the piston just begins to fall again and mark the damper. in the middle of the marks is TDC for cylender #1.
I did this to my buddys truck and my own, he checked his after with a dial indicator on the piston and found we were dead on with the screwdriver.
