Everytime i start my car recently from cold i can here the tappets are bone dry and then after 2 seconds of running they stop being noisy. Is this right for a series 2 RST. I know that they are quite an old car now but its only started happening in the last few weeks, that ive noticed.

I know that the oil level is ok and that it will take a little time for it to be pumped up from the sump. I just wanna know if it could be a regular thing with the RST and if its doing any damage. Car drives fine once left ticking over for a bit and no oil light appears.

Any Advice????? Thanks in advance
