Hey guys,

I am trying to replace my cam shaft synchronizer and I need
Cylinder 1 at tdc. I borrowed a friends compression meter as told by
The manual but I can't get any pressure reads when I crank by hand.
My passenger side is propped up and removed the tire and the tdc is marked
on the pulley, and I alined it with the block marker. But I am not sure
if it Is tdc for 1 or 5. He also told me to drop a pencil in there and watch
For movement. I dont think he realizes that the ohv the plugs go in on the
Side and not the top like his ohc.

So with out compression in my meter, how can I tell if 1 is at tdc?

If you pop the cam position sensor off the syncronizer, the trigger should line up with the big slot in the syncro - like so:


Actually, it should line up better, but if the trigger is on the other side, you're 180 off.

Yeah,

I finished about an hour ago. I just ended up asking a neighbor to put his finger on the line to the meter while I cranked it over. Trying to find tdc on
a v6 is two person job. I started off with putting a pencil in there to watch
the height change and after snapping it, I decided I needed extra help


so far its running but its only been 14 miles, so i'll see if I done it right in a bit

You are likely OK. It doesnt take very long for the PCM to set a CMP code if the CMP signal is out of phase with the CKP signal.
