Cam follower rattle.

Would it be fair to say that as the temperature drops cam followers (1990 Mk1 car) rattle on start up more regularly - I stripped and cleaned these in the summer and changed the oil and apart from leaving the car for several days the followers only rattled on the odd occasion but since the temp` has dropped they do it virtually every time for a few seconds on start up.

Is this normal?

And why have I got a littlle man and lady next to my username?


 I had exactly the same problem, to the extent that the rattle lasted about 10 secs.  Cured by replacing the oil with fully synthetic Mobil1  0W40, currently on offer in Halford’s.  Expensive but well worth it.
