In the process of doing the timing belt. Also cleaned throttle body and ordered Cam and Crank seals. Looking thru videos they are behind the pulleys. Do i just remove the pulleys and the seal will be behind them or are they inside the camshaft? That may be a bit to much for me to undertake, so can i leave them be? I do have 188k on the engine and i read they should be replaced on the second timing belt service. I also read i need to remove the spark plugs before turning the pulleys with the new belt?
