car ticking noise

i have a mitsubbishi l300 express 1983. it has a gh sigma engine in it.
i am having a rhythmic ticking noise coming form the engine bay. it speeds up when i rev.
i recently did some work on the car. changed the:radiator, water pump, fan clutch and blades, radiator hoses, thermostat, flushed cooling system and changed the oil to a 20w 50. i picked a higher grade because i have an older vehicle and in australia so it is hot.
i have tried changing the v belt, trying it without the fan and clutch incase it was inbalanced and tried it on gas incase there was problems with the petrol system but no results.
any help appreciated.

I know many areas of AU are catching world attention for a heat wave. The oil you used is thicker or heavier viscosity not higher quality alone. Hot enough it shouldn't matter but you still shouldn't need to change the viscosity but it might consume more so keep track of it.
Did the noise begin with this work and oil change? If so go back and see what went wrong or what happened. Oil might not be moving properly so go back to a more realistic rating for the vehicle if that's when the noise began.
It's plenty old enough for about anything to cause a noise but probably valve train parts and or adjustment if adjustable. This car is totally unfamiliar to me in the US but it might have adjustable lifters and some good old stuff will cover the ticking and still run well for a good while if adjustable.
Setting those must be done properly or you can burn valves. No easy info for me to know specs if that's the case at all,

i used a higher viscosity because i thought it would help with the older engine. could thee thicker oil mean its not getting in everywhere causing the ticking?
yes, the noise was not there befor, it happened once the work was complete. i don't imagine the cooling system work would cause the sound. the engine doesnt have timing belts or anything, only a v belt working on the water pump, crankshaft and alternator. could the crank shaft have gone faulty?
i know its difficult for people to know exactly whats wrong without physically seeing and hearing it but a list of possibilities can help me through a process of ilimination.
thanks for your help,,

Can you record the noise and upload to a video hosting site and then paste the link in here?

I asked if this just happened with that viscosity of oil. If that's when it began get that oil out for what it calls for as it just might not get to the right places.
Valve train parts can tick and most lower end problem are a dull knock.
General: Oil gets pumped to the most important bearings first with a metered leak down and drips on less sensitive items on its return to the oil pan. If sludged engine the higher heat may have dislodged fudge to the wrong area(s) starving something(s) of oil. Guesses but get the correct oil in it. I know it's hot but an engine does run hot by thermostat tons higher than any recorded air temp on earth. If cooling system can't keep it stable that's its own problem which isn't good either,
