car seat check points

13 years ago I got a caution for possession of cannabis, will this show on a CRB check?

I have been asked to help out with coaching at my sons rugby club but I am worried that the caution will show up and I wont be able to help out. Should I inform the club of the caution and risk my reputation with the club and not get to help out or should I say nothing and hope that the Crb check does not show the caution.
I was 19 years old at the time and I was doing illegal taxi driving when the police stopped me and the person in the back of the car ran off leaving a small amount of cannabis on the back seat of the car. I owned up to the taxi driving and the police said if I said the dope was mine I would only get a caution but if I said it wasnt mine they would do me for the illegal taxi driving and I would be done for no insurance etc and have to go to court and I would get upto a £2000 fine and points. I said the dope was mine and got the caution.

any caution from that long ago is not on your record now.

People will say that it is, but I can assure you that it is not, I had a caution for possession of cannabis, and I had a enhanced CRB check done (Enhanced CRB is done if you are applying to work with children etc) and even I was suprised that it had not shown up, i enquired about it, and the police said that ALL cautions are wiped within Five years
