  • Cam Flats To TDC Question

    On a '95 3.4 Litre, when the front cam flats are up, and the dampener notch is at the arrow, is the #1 cylinder always at TDC where needed to tighten the front cam sprockets?
    We've got the front bank cam sprockets tightened, but when going 1 more revolution to tighten the rear cam sprockets,we went past TDC. Now I don't know for sure where we are at.
    We've brought the front cam to the flats up position with the TDC notch at the arrow. Do we need to just go one more revolution to get the rear camflats up and then be able to tighten the rear cam sprockets?
    TIA,

    If you go past the mark, you have to turn the crank 360 degrees, and then another 35x to get to where you need to be. Sounds like what you are saying to me. Number 4 (middle front bank) will be at TDC when the front cam flats are face up.

      What does "35x" mean?
      So, with the front cam flats face up, 1 crank revolution makes the rear cam flats face up?
      If so, the front bank sprockets get tightened first, then the rear, right?
      Sorry for all these questions. It's just that I want to get it right.

        35x would be somewhere between 350 and 359 degrees. Since he said the number 4 piston will be at TDC, that will be where you need to rotate to. You don't want to go a full 360 degrees since you already went slightly past where you needed to be, hence the 350-ish rotation.

          Yeah, I didn't wanna say another 360 degrees cause that would put you back to where you were. Might have been easier to understand though:P

            Oh, Sappy meant degrees. I did not even think of that. Excellent.
            Thanks guys.
            I'll hopefully have the engine ready to run today.
            I ended up going with the stock flats up cam timing for now. I'll wait and buy the timing tool when it's ready and reset the timing later. Right now I have to get the car back on the road.
            BTW, In order to be as precise as possible to align the dampener TDC notch to the arrow, I placed a piece of grey duct tape on the engine cover arrow area. I then laid a small straight nail on/into the notch, holding the nail flat on the dampener and in the notch, I slid the nail point into the duct tape to make a small hole that is easy to see.
            It was then easy to use a mirror to view the alignment of notch to "hole" as though looking from the front of the engine (not above).
