Ha - JR beat me to it while I was (slowly) typing ....

I seem to remember a couple of threads from Raby suggesting that the lifters can fill up with gunk (which can't escape due to no oil exit arrangement) and they don't respond well to detergent flushes. I'm pretty certain that he modifies standard lifters in his rebuilt engines - what the mods are he wont say....
Are you sure its lifters? why would cold(er) weather make any difference, especially of you are using the correct 0W40 or 5W40 oil grade?
Could it be the dreaded bore wear "tapping" noise that affects the bigger capacity M96 engines on cylinders 5 & 6 - what is you oil consumption like?
I'd try new synthetic oil and see if the noise reduces.
