When I first got the car in about 2001 and 170k on the clock it used to regularly have trouble with the hydraulic valve sticking in the cold and that's why I changed to fully synth lube oil which cured the problem. I'm not convinced though that the various brands of fully synth lube available all work as well in this respect.
Thanks

While mineral ATF will work Garth, it takes a lot longer. Whichever one you use (you could just go and buy a litre of ATF-U), once it's in there, leave it to do its work for quite a while. On my Jeep that had noisy tappets, (and usually only ran on 4 out of 6 pots), it took about 1000 miles to free them up properly.
It's possible that because you're using synthetic oil in the engine that the mineral ATF will work a bit quicker. However i've not tried that so i can't be sure.

Good luck with it and hopefully it saves you a stripdown job.
