Rover 25 K16 Timing belt
(Background- Bought a Rover 25 1.4, which recently had new headgasket done by previous owner however, the original timing belt was refitted which is 13 years old and 53k (Silly and half of a job I know!)
I have started the task of replacing the timing belt myself and I am having trouble getting everything lined up.
It would appear that which ever 1diot put the belt back on, has timed everything up from the crankshaft being set using using the TDC line on the lower casing (Last of the multiple lines) rather than 90BTDC at the 12 o clock position on the engine.
I think this because I can only get the inlet and exhaust sprockets to line up correctly when the crankshaft cog is lined up with TDC and when alined with 90BTDC, the inlet and exhaust sprockets are out by a mile.
The engine has been running fine with no misfires just a slight judder when the engine is cold and the engine seemed quite flat with no urgency....
My question is..... If I align the bottom crankshaft cog to the 90BTDC mark on the engine, providing that this doesnt move, is it then safe to turn the inlet and exhaust sprockets freely and get them aligned to --Ex o In- -Ex o In--
