Oh, to be clear, I haven't done this before, on any vehiculre... so if you see something wrong, or, well anything. I am planning on getting an new crank pulley anyway, this one is cracked and welded by the PO, trying to find one at the wrecking yard first, I'm on a budget and this is looking expensive already. I'm going step by step and doing my best to get everything along the way. trying to decide what all to replace as well as preventative maintenance as I'm in there. timing belt looks like its in good shape, no idea if the water-pump was done at the same time, going to check the pulleys at the same time, not sure if I should dig deeper when I am doing this. ie pull the cam shafts, lap the valves ect. I know I had a knocking sound so I suspect one of the hydraulic lash adjusters may be bad. Should I replace the valve stem seals while im in here? no evidence it's needed but, you see where im going with this I hope.
