Thread: Need help of timing setting on a 2007 Range Rover Sports SC v4.2

To mechanic who has experience of L320 camshaft timing setting,

Hi, I'm a new fish of this forum, from Canada. I'm dealing with overheating of my 2007 Range Rover Sports SuperCharge V8 4.2. I tried replacing coolant radiator, coolant reservoir, waterpump, thermostat, main hoses, but nothing better. After running 20mins, it will overheat. High Temp and Coolant low warning like evil. I decided to check and replace the head gasket finally. When I opened the front cover, I am confused very much about the camshaft position. Special tool has been inserted from the crank position sensor hole to lock the timing, but the current "correct timing" is like the pic I posted below. Only the intake camshaft has the flat surface up, and I can't see the exhausted camshaft flat at all. So I can't install the special tool on it to lock the camshaft. In another word, I am confused how to put this timing back by the special tool acrossing on the camshaft cap #0 and #5 if I remove the camshaft rod. Both sides are the same situation on LH and RH. Anybody know if this is correct? And how could I install them back if I remove the cam rod? SOS!!!

[edit] sorry got mixed up with SCV6 and SCV8, though possibly they are the same engine, the v8 just not having the last 2 cylinders blanked...

Thank you. I got it. Just turned the crankshaft one more round, then the two flat surface were shown up because crankshaft two round equal camshaft one round for most all 4-stroke engines.
