Is the tick present when you first start up the engine? If so, does it gradually go away after it runs for a couple of minutes?
The difference in 5w-20 and 5w-30 oil weight is negligible if the outside air temperature is above freezing. Now, if you are running a thicker Xw-40 or Xw-50 weight oil, that could definitely cause the engine to tick like crazy when you first start it up...

its actually the opposite it seems to be it is not there when i first fire it then it starts slow then gradually becomes a constant noise it is spinning at the camshaft speed fore sure not to mention i have rebuilt the complete lower end of this motor. thats why i was thinking as the oil thins when it is warm a lash adjuster(lifter) is collapsing under thinner oil conditions??
but its surely pissing me off i got the car last friday with a blown motor and have been working my ass off to get it straight but it seems one thing after another. i have changed all lash adjusters and rockers or cam follwers and going to try this!
