timing cover area oil leak

[lesboy]

Hi folks

has anyone suffered Oil leaks from the round plastic inspection cover attached to timing cover on 2.2 diesel engine, as my previous posts I had major work done a while ago when this was removed, it initially leaked when fitter had not secured it properly this rectified and ok for a few weeks now slight leak evident in that area again it is a mickey mouse thing with a bayonet type twist fitting , not certain it is leaking from here but fitter has suggested getting a new one !!! I have looked everywhere but seems only available from Jaguar and costs about £32 inclusive of vat which seems a joke for something which I bet costs about 50pence to make, any ideas or has anyone got one cheaper.

thanks guys .

Les.
