when I removed the head, I made sure not to remove the chain of its wheel. so I would position the camshaft on the same position again and dont hussle into the timing settings.

I installed the head, then turned the camshaft to fit the position of the chain wheel. bolted everything together and turned it on...

I turned it on and a fast and loud ticking was heared. engine wouldnt start too. fast is like the speed of the engine when it's running idles 4 ticks / second.

would the camshaft take 2 positions one is totaly off synch. or is the the oil pump jamed since there was water in the oil and car was off for more than 24 hours.

please advice..... thanks
