installing sprocket/timing chain

[hf240z]

hi everyone,

i replace my 240z(72) motor with a 280z motor from an 83. it was very powerful motor compare to my dying 240 motor. i use it for 1 day, and unluckily i burst a water hose(old) and the motor overheated. head gasket is broken. i replace it (my first time). everything went smoothly except when i am about to install the sprocket and timing chain. it just wont reach the cam. i lift the sprocket with the cherry picker it wont go, i use a crowbar to left it , nothing move, i turned the crank to check if i have a kink down the crank, nothing , it turns ok.

if you have done this before, or have an idea how i can install it without opening the whole front, please let me know.

thank you so much,

Unfortunately you've dropped the chain and the tensioner has popped out.

Your only solution is to remove the timing cover.

See the thread under this for more info, Why did I bend a valve etc?
